In the current world a large number of people have cars for personal use. But given so many cars on the roads, not every one of their owners has a garage in use where they can store useful things for their iron horse. It is far from a secret that a car requires personal care, it is especially pleasant to drive a clean car. To wash the car, it is not necessary to constantly stand in line for washing, or to buy a washing machine. In order to save money and time, you can make a mini-sink with your own hands, it will fit in the trunk, and you can use it anywhere.
Materials and tools:
- Plastic canister with two necks
- hose from washing machine 2 m long
- Watering gun on the hose
- quick-detachable fitting
- Tubeless tire valve
- Rubber gasket
- Coupling
- Screwdriver and drills
- Rubber adhesive or sealant
- Automobile compressor
Step one. Mounting the air inlet.
Having collected all the materials and preparing the tools, you can get to work. First of all, the author removes the lid from one neck (responsible for draining). Picking up a drill with a thick drill, he makes a hole in the center of the lid.
Note: when the sink is ready, when using the canister, you will need to lay it on its side, with the fill hole down (so that the water comes out under pressure). Therefore, the cover of this outlet is left for the junction with the hose.
The valve for the wheels is pressed into the hole of the drilled cover. Now you need to let the sealant dry.
Step two. Water outlet installation.
In this step, it's time to prepare the second lid. It is removed, and the drill is taken up again, only now the pen drill is already used. A hole is made in the cover in size corresponding to the diameter of the coupling.
A coupling is inserted into the hole prepared in the cover.
For better fixing on the lid, the joint of the coupling, as in the previous step, is watered silicone sealant, after which this cover also needs to be dried.
Fastening is no longer needed, only a nut is needed, it is attached back side couplings. The connection is also secured with a sealant.
After drying all the connections, you can put the cover back in place.
Step three. Watering gun to hose connections.
The idea to use a hose from a washing machine came to the author for a reason, such a hose has the ability to withstand high water pressure. The cut off part of the hose is threaded into the union nut.
The hose section is fixed in a quick-detachable fitting using a special fastener.
The main fitting and its nut are twisted.
Now you can connect the fitting to the watering gun on the boom.
Step four. Connecting the hose to the canister.
In order to prevent air from escaping when water is supplied under pressure in the future, the author inserted a rubber gasket right size into the second hose nut.
The nut is screwed onto the quick-release fitting.
On this, the assembly of a homemade mini-sink is ready!
Step five. Washing test in operation.
Water is poured into the canister.
Washing high pressure DIY can be created from inexpensive parts. Such units are widely used. With the help of the device, you can wash the terrace of a house or cottage, wash a car and do many other operations that require the presence of high pressure water. Anyone who has the simplest tool skills can do a wash. By appearance homemade unit looks like a portable suitcase small size or polisher. Its body is made of silumin or plastic.
How does a car wash work?
An electric motor is installed inside the unit, the shaft of which is connected to a plunger inclined washer. The plunger during movement describe a reciprocating trajectory. On the upper and lower sections of this curve, the valves open alternately: suction and high pressure. Through these devices, water enters the hose, and then into the sprayer. What are the technical characteristics of such a sink?
For determining required power such a device, you need to know how often you plan to use it. With a high frequency of work with such a sink, its power should be increased - the performance of the device increases along with an increase in the pressure of the water jet. The efficiency of the entire device is 75-85% dependent on the flow rate of the liquid. It must be supplied to the unit required amount otherwise the washer may be damaged.
The temperature of the water used must be within the operating range applied in the pump device. Usually this indicator has a spread within 55 degrees. Creating such a sink does not take much time, saves money and finances. The advantages of creating such a homemade unit are as follows:
- There are no components of increased complexity in the device.
- It's simple to use.
- The efficiency of such a unit is on par with samples purchased on the construction market.
- Low probability of damage to any treated surface.
- Possibility if necessary self repair devices.
What does a homemade mini-sink consist of?
You can make a sink from such details as:
- High pressure pump.
- Electrical engine.
- A special coupling that connects the first two positions.
- Tank for water and detergents.
- Main frame.
- A pistol equipped with a nozzle.
- High pressure hoses.
- Various nozzles.
Such a unit works according to the following principle: after turning on the unit in water supply network water passes into the container, where it is pumped by the pump. Then it is fed to the hoses and through them is sent to a gun with a nozzle, through which any surface is cleaned, for example, the hood of a car.
What parts are needed to assemble such a device?
First you need to buy a pump. it main detail homemade units of this type. It should have a sufficiently high performance at a pressure of 0.1-0.2 kilobar. Special attention must be given to the material from which it is made. It is necessary to choose a model in which the head on the cylinder block is made of brass, and the pistons of the pump itself are made of high-strength steel or ceramics. The duration of the created sink depends on this.
The other main part of the unit is the electric motor. With an increase in its speed, the performance of the washing pump also increases. For similar devices electric motors with a power of 2-3 kW are best suited at a shaft speed of 1.5-2 thousand revolutions per minute. To ensure the reliability of starting the engine, it can be equipped with starting capacitors.
The coupling must be soft: if the pump or electric motor is jammed, it will play the role of a fuse.
The water tank can be selected from 5 to 22 liters. At the outlet of this vessel, it is desirable to put a filter. Usually this role is played by a fine mesh. It traps unwanted particles that enter the water and prevents them from entering the pump.
The frame is the base on which all elements of the sink are attached. Most often it is made from curved pipes. On it you can fix the emphasis and wheels, which will make it possible to move the sink. The frame has handles for carrying it around the work site.
For hoses, plastic and rubber sleeves with reinforcement inside are best suited. Their thickness is selected with an average diameter. All their connections in the unit must be tight and made of a material that is not afraid of corrosion.
A pistol with a nozzle must be chosen so that its trigger works smoothly, without jerking. Tips are bought ready-made. The sink can be equipped with several nozzles that will create the desired jet shape.
How to properly operate a homemade sink?
In order for the unit to work for a long time without breakdowns, it is necessary to follow the recommendations of the following nature:
- Before work, you should always check all connections and fasteners for reliability.
- If there is a filter device at the outlet of the water tank, then it must be cleaned every day after work from particles and dirt.
- It is not necessary to frequently use the washer in the maximum power mode, as this dramatically increases the load on the pump and can cause it to fail.
- To protect the sink from power surges, you can equip it with a battery.
- In the working position of the apparatus, the gun must always be in the operator's hand.
- It is better not to allow children to wash: this can lead to an accident.
- Water jets must not be directed at people or animals.
- This machine must not be used at temperatures below zero degrees Celsius.
If you need repairs, you can do it yourself. But this is the case if the design of the sink is known. Most often, wear occurs on the seal in the pump itself. This can lead to a sharp drop in its performance. In this case, it is necessary to disassemble the pumping device and replace all gaskets.
In some designs of such devices there is a pressure regulator. When its seals (rubber rings) are worn out, the water pressure decreases and the density of the liquid jet decreases.
To fix this problem, you just need to change the seals in the pressure regulator.
Technological process of device assembly
Tools needed for work: tape measure, electric drill, hacksaw, spanners, bolts, nuts, washers.
The main point in creating the structure is the grounding device. To make it, you need to use a flexible cable with three cores. It must be double insulated. Then it must be connected to a plug with a grounding terminal. After that, you can connect the device to the main ground loop.
Then proceed to the installation of the sink on the frame. The sequence of operations is as follows:
- Install an electric motor with a starting device. This is done using bolts inserted into the corresponding holes on the frame.
- Install the electrical cable.
- They put the pump and mount the coupling on the motor shaft.
- The nozzle gun is attached to one of the high pressure hoses that extends from the pump outlet.
- Attach the water tank to the frame. Make sure that all connections are tight.
- Finish the installation by installing all high pressure hoses.
Now comes the stage of checking the operation of the device. To do this, the sink must be connected to the main water supply using a hose, which should be 7-8 meters long. Open the faucet and draw water into the tank. After that, turn on the electric motor. The pump should pump water through the hoses to the gun. They press its trigger and see if the density of the outgoing liquid jet satisfies or not. If everything is in order, then you can use nozzles to get different types of jets for cleaning various surfaces. If the water does not come out in the volume that was supposed to be obtained, then you need to check all fasteners and seals and then repeat the check again.
It is possible to use a car wash for cleaning dirt from a car and other similar operations, provided that the operating rules are followed.
Homemade car wash correct work it can last a long time with it.
High pressure washer - convenient fixture, which allows you to easily wash the car, as well as other surfaces in everyday life. thanks to the strong pressure of water, such devices are able to clean even heavily soiled surfaces without the use of detergents.
Such devices are usually installed at car washes and cost a lot of money. The Karcher pressure washer deservedly gained popularity, but not everyone can buy it. Therefore, for use at home, you can make a car wash with your own hands. - a great alternative to professional ones, which you can assemble yourself from improvised means.
To make a Karcher pressure washer, you need to find suitable materials. You can use improvised items or purchase new ones in the store. So, to create a minisink you will need:
The principle of operation of the device
Will work on the principle of conventional car washes. The water in it is supplied through a rubberized hose under high pressure. Air is pumped into the water tank by a car pump, which creates excess pressure in the tank. Water under pressure is supplied to the outside and is supplied when the trigger of the watering gun is pressed. Thanks to the strong pressure of water, with the help of a car wash, you can clean any surface.
In this case, the pump is used exclusively for pumping air into the tank. Replace the constant use of the pump, you can install a pump that allows you to manually raise the pressure. Also, plunger pumps are an alternative to automobile pumps.
Plunger pumps - modern devices, which belong to the hydraulic dosing type devices. The plunger pump independently mixes water and detergents in selected proportions and delivers the mixture under high pressure. The disadvantage of installing such a pump is the excessive final weight of the car wash.
How to assemble a car wash with your own hands
Initially, you need to prepare a water tank. For this, using sharp knife in the lid of the canister, it is necessary to cut a hole, which in diameter will be narrower than the nipple. After that, through inside cover is threaded with a nipple.
Advice : If the hole is larger than required, the gaps must be additionally sealed.
Through the nipple in the lid, the pump will pump air into the tank, and water and detergents will also be filled.
Next, you need to prepare a system for connecting the canister to the watering gun. To do this, in the lower part of the canister, you need to cut a hole close in diameter to the coupling. The clutch is attached from the inside of the canister, you can start it with a piece of wire. After threading the hose connector, sealant must be applied around the circumference. A fitting is also attached to the coupling.
After the sealant has dried, you can begin to prepare the sink for work. To do this, plugging the fitting with your finger, you need to pour water into the canister. Also, any detergents can be added to the tank (specialized detergents for cars or household chemicals). The nipple must be connected to a car pump and gradually pump up the canister with air. During this action, you need to ensure that the canister does not inflate too much. If it was decided to install a plunger pump or pump, then they are attached to the fitting using connecting hoses.
After completing these steps, a rubber hose is connected to the fitting, at the end of which a watering gun must be attached.
Advice : You can check the correct assembly by pressing the trigger of the gun. If, as a result, a strong pressure of water began to flow from the gun, then the device was assembled correctly. If this does not happen, then the canister is leaking air and you need to check all connections again and, if necessary, treat them with sealant.
The cleanliness of the car must be monitored so that accumulated dirt containing aggressive chemical compounds, did not destroy paintwork and metal parts cars. In order not to waste time and money on visiting a car wash, you can design a pressure washer yourself.
1 How a pressure washer works - construction and other details
The advantage of high-pressure washing is that the car body, engine compartment and bottom can be washed from dirt with a directed water jet. Such devices are installed on professional car washes and cost big money. Great alternative device Karcher can become a homemade sink. The principle of operation of a pressure washer is the same as that of a conventional car wash.
First, air is pumped into the tank in which the water is located using a pump or pump. This creates excess pressure in the water tank. Water is supplied to the outside through a rubberized hose when the trigger of the watering gun is pressed. The pump is needed to pump air into the tank. You can use a car or plunger pump. The convenience of the plunger is that it belongs to the hydraulic devices of the metered type. According to the selected proportions, the plunger unit mixes water and detergents, and then delivers the mixture under high pressure.
A homemade pressure washer has several advantages:
- the parts necessary for assembly can be purchased in stores or adapted from improvised materials;
- assembled quickly and easily;
- easy to use at home;
- it is possible to increase functionality by installing additional equipment;
- the main plus is low cost compared to professional counterparts.
2 Selection of electrical components - motor, pump and gearbox
The main element of the sink is the engine, which will supply a jet of water. You will need a powerful pump that could create pressure up to 150 atmospheres with a capacity of 15 liters per minute. In normal operation, it should use 80-90% of its rated power. It is advisable to select a pump with a power supply of 220 or 380 V. It can be made from car compressor or refrigerator compressor. It will cost less, but the performance will be lower.
When choosing a unit that supplies water, you need to pay attention to the materials from which it is made. It should have a high strength ceramic or metal piston. To make the design more durable, the head should be made of brass or bronze alloys. For homemade car wash a small power motor is suitable - 200-200 watts. It is better to choose a single-phase motor: it is safer to connect it, and it is more economical.
The design of the car wash can include a gearbox and a condenser. The capacitor bank increases the number of revolutions, which will increase performance. Installing a gearbox in the form of a belt drive with one stage will make it possible to balance the load and speed between the pump and the motor. To connect the motor and pump, you must purchase a coupling that will ensure the safety of these components. It is better to buy a soft coupling, with which it will be possible to compensate for small deviations between the shafts.
3 Additional materials for homemade washing
A necessary element is a container for holding water, which will be used for washing. It should be from 5 to 30 liters in volume so that you do not have to fill it often. Can be used as a container plastic canister or bottle. It should be noted that there are no seams on its bottom. A fine mesh filter can be installed at the inlet or outlet of the tank, which will protect the pump from debris.
Hoses should be selected plastic or rubber with reinforcement, about 5 meters long and with an average diameter. Connections must be securely sealed. This is ensured with the help of clamps and sealant, which is applied at the joints. It is desirable that the design be collapsible and maintainable, so threaded connections should be used whenever possible.
Water is supplied through the gun by pressing the start key. When choosing a pistol, pay attention that the key works smoothly, without jerks. To facilitate the washing process and create a jet of water of a certain shape, you need to purchase various nozzles: rollers, brushes of different hardness, sprayers. All parts of the installation are mounted on a frame made of round and profile pipes. Wheels can be attached to the down tubes for easy transport. You should also provide stops for fixing the installation and handles for moving.
If you need to wash the car at a low temperature, you can make a foam generator with your own hands. Using such a device, you can evenly apply fine-grained foam from the washing solution to the car, which allows you to qualitatively wash the surface from dust and adhering dirt.
To obtain foam, water mixed with detergents, is sprayed with a stream of air that passes through the installed channels, and then mixed with a foaming tablet in a special unit. The flow is regulated by means of special plates.
4 Features of manufacturing and operation - assembly in 4 steps
Having prepared all the necessary components of the mini-sink, we combine them into a single design:
- First, we prepare a tank to connect the pump and fill in the washing liquid. In the lid of the prepared container, we make a hole for the nipple through which the pump will pump air and water with detergents will be poured. If there are gaps, they must be treated with sealant.
- Next, at the bottom of the tank, we prepare a hole for connecting a watering hose with a gun. We fasten the coupling from the inside and perform a thorough sealing.
- When the tank is ready, we fix the main installation to it with the help of soft connections. We seal all connections using a special sealant.
- From below we carry out a watering hose with a gun and check the performance of the car wash.
For safety reasons, the system must be grounded. To check, turn on the installation in the mains. In this case, you need to ensure that water does not get on the wires. If the assembly is done correctly, then after pressing the trigger, a powerful jet of water will begin to beat from the gun. If there is no pressure, then the seal is broken, you need to check all connections.
In order for the installation to serve you for a long time, you need to follow a number of rules during its operation:
- Before each use of the car wash, check the tightness of the connections.
- Do not use strong water pressure very often, as this puts a large load on the pump and leads to rapid wear.
- For effective work mini-sinks, it is desirable to use various nozzles.
- If filters are installed at the outlet of the tank, they must be cleaned of accumulated dirt and debris after using the unit.
- To protect against power surges, the installation should be equipped with a battery.
A device such as a pressure washer has received wide use in the modern economy. With its help, you can wash a car, a terrace, a house, etc. At the same time, it is quite possible to build a sink yourself, without having any special skills.
The pressure washer is presented in the form of a cleaning device with which you can clean different surfaces supplied with high pressure water.
Externally, the household mini-sink is a compact, small in size apparatus. The case is made of plastic or silumin (materials that are sufficiently resistant to mechanical stress).
Scope of use of the device: cleaning various surfaces(car body, furniture, asphalt, tiles and more).
The principle of operation of a pressure washer.
Inclined inside the device the puck is spinning under the action of an electric motor. The plungers located on the washer move along a forward-return trajectory. At the top and bottom of the trajectory, their movements are opened, respectively. suction valve and high pressure valve. He is responsible for supplying water through the hose to the sprayer, forming a set.
Device Specifications
- The power of the device is determined depending on the planned frequency of use of the sink: the more often we want to use the device, the more powerful the device we need. There is a direct relationship between the washing power and its productivity: an increase in power entails increase jet pressure.
- Water pressure and flow rates are one of the most important characteristics. The level of efficiency of the device depends on them by about 80%. Important: for fruitful work the correct amount of water must be supplied to the sink, determined on the basis of its specifications. For example, water consumption the machine is equal to 360 l / h, and the water supply is only able to supply 200 l / h, this can lead to a breakdown of the sink.
- No water temperature indicator cannot be exceeded, because the built-in pump is designed for a certain temperature. Usually the indicator varies within 50 degrees (for semi-professional and household devices).
Homemade mini-sink project
The proposed mini-wash project includes next set main elements:
- pump;
- electric motor;
- coupling for connecting the first two positions;
- container for water and detergents;
- frame;
- nozzle gun;
- high pressure hoses;
- nozzles.
The principle of operation of the manufactured sink is very simple. After plumbing connections water enters the container, where it is pumped using a pump.
We prepare material and tools
To make a mini-sink, you have to get the following components.
The pump is one of the main components of the sink. Device performance should be high enough(range of developed pressure: 100−200 bar). When choosing a pump for a mini-sink, you should pay attention to the material of its manufacture. It is desirable that the cylinder head be made of brass, pump pistons - made of ceramic or durable metal. The period of operation of such a pump will undoubtedly please you.
A pressure washer cannot be imagined without an electric motor. Obviously, with increasing engine speed pump performance increases, and hence the device as a whole. However, don't overdo it. The best option electric motor power - from 2 to 3 kW, rotational speed - 1500-2000 rpm. To provide reliable start motor, an additional capacitor bank can be used.
The coupling connects the pump to the motor. The so-called soft clutch - the most acceptable option. It plays the role of a fuse in case the pump or motor jams, and can also compensate for minor axial misalignment of the shafts.
The optimal volume of the water tank is from 4 to 20 liters. It is recommended to install a special filter (fine mesh) at the outlet of the tank, which can trap particles of dirt and debris, preventing them from entering the pump.
The frame is the basis for fastening the elements of the sink. traditional material its manufacture curved pipes. Often, wheels and an emphasis are attached to the frame so that the mini-sink can rely on them during operation. The handle on the frame will provide device movement by territory.
A rather serious function is performed by a pistol with a nozzle - forms a shape water jet. When you press the handle, liquid is supplied, this saves water. It is better to buy a tip ready-made, so as not to "puzzle" over the design of the shut-off valve.
The device is usually equipped with a nozzle (or several), which forms a jet that is most convenient for washing various surfaces. As a tool in the process of construction device you will need a knife, scissors, sealant.
Do-it-yourself mini-sink assembly technology
One of the most important nuances when assembling the sink is creation of grounding. For these purposes, use a flexible three-wire wire (double insulated) and a plug with a grounding terminal. At the same time, through the contour the socket is grounded.
The next step is to mount the sink on the frame, i.e., do the following in sequence:
- Installing electrical.
- We mount the gun with a nozzle.
- We carry out installation of a sleeve of a high pressure.
When equipping the water tank with a pump, make sure that all connections are durable and sealed. It is also very important that the device is mounted in accordance with the recommendations of the parts manufacturers.
Connecting a high pressure washer to the main water supply with a hose (acceptable sleeve length - at least seven meters).
Features of operation and repair
To prevent breakage and further repair of your mini-sink, you should listen to the following simple recommendations:
- do not allow children to play with the device;
- in the process of using the sink, hold the gun firmly in your hands;
- do not direct the jet of water at animals and people;
- do not use the device at temperatures below 0 °C.
If, nevertheless, your device needs repair, it can also be done by hand, provided that you know the design of the device.
So, what can break?
- The most common case is seal wear in the pumping mechanism, which leads to a significant decrease in its performance. In this case, the seals must be replaced.
- Rubber rings can also wear out. in the design of the regulator pressure (if installed). A "symptom" of such a problem may be a decrease in pressure and density of the jet.
Do-it-yourself high-pressure washing device will not take you much time, in addition, will save you money. Among other advantages of such a homemade device:
- lack of complex components of the device;
- ease of use;
- work efficiency comparable to purchased devices;
- very low probability of damage to the treated surface.
The benefits of a mini-sink in everyday life are undeniable. On condition competent use the device saves you time and money, providing you and your family with cleanliness and comfort.
