Do you know what a car wash pump is and how it works? Stay with us to know it

Industrial car wash pumps are of piston type, in this type of pump, the suction and pumping of water is done by the reciprocating movement of the piston in the cylinder, which due to the positive displacement movement they have the ability to produce water with high pressure but low flow rate. In washing in the traditional way (for example, consider washing the yard with a hose), a very large volume of water comes out of the hose with low pressure, which does not have much effect on removing dirt, and most of the time we have to play the role of the nozzle with our finger and drain it. Let’s reduce the water but increase its pressure, which is done in high quality car wash pumps.

In simple words, the working method of high pressure car wash pump devices is such that first the water entering the pump is supplied by a water tank or city tap water with suitable pressure. The water is connected to the pump inlet by a normal hose, the pressure of the water entering the pump increases, and the high-pressure water is thrown out after passing through the pressure relief valve, and this increase in pressure reduces water consumption and also increases the quality of cleaning. It becomes pollution. The water coming out of the pump reaches the lance, which is also known as a gun or car wash gun, by a high pressure hose, and the water is sprayed on the pollution in the form of a broom or a paddle or a needle, depending on the type of nozzle.

As a work facilitator, the car wash lance can have different dimensions and models. In the cut-off or trigger type, the lance has a trigger like a gun, and to start working, it is necessary to press the trigger after turning on the device. As long as you don’t release the trigger, water will flow from the nozzle, but as soon as you release the trigger, the water will stop. However, this is not the case in Gan Sereh, that is, turning the water off and on is done by turning the device on and off. This can be facilitated by installing a switch near the lens.

The use of trigger guns is not recommended at all, especially for car wash environments that are washed several hours a day, because if used, it will damage the pump that has created a lot of pressure in the circuit and you have prevented the release of pressure with a trigger. It is serious.

There is another type of gun whose opening is angular or convex. This type of gun is used to wash places that are not easy to access, such as under the car. This type of gun is also known as underwasher lens. The standard lances used in car washes are one-meter long.

Most of the piston pumps are offered in two forms, workshop coupler and fabric coupler. In direct coupler or hollow shaft pumps, the pump and dynamo are connected directly and without intermediaries. In workshop coupling model, pump and dynamo are connected by a coupling.

In general, the factory coupling pump has higher efficiency, its energy loss is less, and its useful life is also longer compared to workshop coupling pumps, but workshop coupling pumps are more demanding due to their more reasonable price and availability. have.

This type of device, whether it is a workshop coupling or a factory coupling, is called a coupled carwash industrial pump.

These devices are offered on three types of chassis:

The first type of fixed chassis: this type of chassis is used in all car washes.

Second type: mobile chassis or wheel and handle which can be like a cart with 4 wheels or like a wagon with one wheel.

The third type: the chassis is covered. In this model, the pump and dynamo on the second type chassis are protected in a hinged metal enclosure called a cover to prevent shock or water damage. This type of chassis is very suitable for cleaning companies that offer mobile services.

What is common in car washes in the city is that for a 110-bar pump, a single-phase dynamo of 3 horses or 2.2 kilowatts, with an engine speed of 1450 rpm, and for a 207-bar pump, a three-phase dynamo of 7 horses or 5.5 kilowatts. With an engine speed of 1450 rpm, it is used on a fixed chassis that is protected in the installation room. Also, the car wash coupler pump, which is used in washing heavy cars, is 345 times and needs a 13 horsepower dynamo.

In general, piston pumps, which are also called high-pressure plunger pumps, are used in cases where high output pressure is needed, usually from 100 to 1000 bar.

Their main uses are in car washes to wash cars, chicken farms to clean waste and maintain humidity in poultry farms, foggers to cool the environment, in open spaces, greenhouses, and to clean all types of flooring and surfaces.

Now that you are generally familiar with the concept and function of the car wash pump, as an example of a high-use product, the Italy comet pump model LW3016S is introduced:

The practical pressure of this pump is 110 bar and its output flow rate is 11.2 liters per minute. The single pump LW alone weighs 4.8 kg and its power is 3 horsepower.

General Tools company offers the above pump with a 2.2 kW 1450 revolutions Motogen Tabriz dynamo on a fixed or mobile chassis, along with a gun, a nozzle and a wire pressure hose. The length of the hose can be customized, although for a 110 bar pump, the standard length is a maximum of 10 meters to prevent pressure drop.

This standard size is 20 meters for the 207 bar pump and up to 50 meters for the 345 bar pump.
