What Is a Pressure Washer?

High pressure washer is a machine that uses high power plunger pump to produce high pressure water to wash the surface of the object. It can peel off dirt and wash away, and achieve the purpose of cleaning the surface of objects. Because the high-pressure water column is used to clean up the dirt, high-pressure cleaning is also one of the most scientific, economical and environmentally friendly cleaning methods in the world.

The impact of water is greater than the adhesion of dirt to the surface of the object. The high-pressure water will peel off the dirt and wash it away, reaching a cleaning device that cleans the surface of the object. Because the high-pressure water column is used to clean up the dirt, except for very stubborn oil stains, you need to add a little detergent, otherwise the foam produced by strong water pressure is enough to take away the general dirt ^.

It is inevitable that the washing machine will malfunction during use. When a problem occurs, you should carefully find the cause according to different symptoms.

1) The spray gun does not spray water

a) into

1. Cleaning and maintenance of various motor vehicles, engineering vehicles, engineering machinery and agricultural machinery supporting products, such as washing cars,

1.Depending on the amount used :

General high-pressure cleaners can be divided into home and professional use. If you use the washing machine for less than 50 hours a year, you only need to buy a household washing machine. The price is relatively cheap, the weight is light, the material is simple and heat-resistant. If the use time is more than 100 hours, it is necessary to consider a professional high-pressure cleaner, which has a large volume and uses a copper alloy pump head,

Routine maintenance-after each operation

1. Flush hoses and filters connected to the detergent to remove any detergent residue to help prevent corrosion.

2. Turn off the water supply system connected to the pressure washer.

3. Pull the trigger on the servo spray gun lever to press all the pressure in the hose

1. When operating a pressure washer: Always wear appropriate goggles, gloves and masks.

2. Always keep hands and feet away from the cleaning nozzle.

3. Always check all electrical connections.

4. Always check all liquids.

5. Check the hose frequently for cracks and leaks.

6 · When the spray gun is not in use, always set the setting trigger to the safety lock state.

7. Always use the lowest pressure possible to work, but this pressure should be sufficient to get the job done.

8 · Always release pressure from the washer before disconnecting the hose.

9. · Always drain the water from the hose after each use.

10 · Never point the spray gun at yourself or others.

11. · Never start the device until all hose connections have been locked in place.

12. · Never switch on the equipment until the supply water is switched on and appropriate water is passed through the spray gun shaft. Then attach the required cleaning nozzle to the spray gun shaft.

Note: Do not leave the high pressure washer unsupervised during operation. The pump will run in bypass mode every time you release the trigger. If a pump has been running in bypass mode for a long time, the excessive temperature of the circulating water in the pump will shorten the life of the pump and even damage the pump. Therefore, avoid running the device in bypass mode for a long time.

Market Analysis of High Pressure Washing Equipment

Analysis of market survey results found that high-pressure cleaners have broad market development potential in China. High-pressure cleaners in developed countries have been widely used in homes, so the market demand is very large, and it is still expanding. the trend of. However, the market analysis of the domestic market found that the domestic high-pressure washing machine market should still be in its infancy, the use of high-pressure washing is still very small, and it is limited to large and medium-sized enterprises. However, with the rapid development of the economy, especially the rapid development of the automotive industry and the popularity of automobiles, people have gradually improved the living environment and the quality of the living environment. The domestic high-pressure flushing equipment market has also rapidly increased. Market demand is also increasing rapidly.

The electric control cabinet is made of steel plate, which is waterproof, dustproof and has a certain strength. It can support and protect electrical switches, inverters, PLC and other components, and its surface is anti-corrosive.

The system is composed of circuit breakers, inverters, PLCs, sensors and intelligent instruments, plus the necessary connecting wires and accessories, which can meet the working conditions of the washing machine, are easy to operate and have superior performance.

The control of the washing machine is performed by a circuit breaker as a power switch, a control module composed of a frequency converter and a PLC, and the pressure and flow signals are converted to transmit and accelerate the deceleration of the frequency converter according to the needs of the work.

After the water pressure measurement data of the washing machine enters the control module, the output of the pump motor is automatically adjusted by the inverter according to the increase or decrease of the number of water guns working on site to meet the water pressure and flow required by the field work.

working principle:

Power switch: Close the air circuit breaker and connect the 380V / 50Hz power supply. The washing machine is ready to work.

Control module (PLC and inverter): Receive external signals in real time and automatically start according to the pressure change of the water gun and the pressure of the washing machine to achieve the water gun opening. The increase of the water gun automatically increases the output of the pump motor (or the decrease of the water gun reduces the output of the pump motor) After all water guns are closed, the machine will be delayed.

Pressure switch: Real-time monitoring of the differential pressure change in the tube and output the switching signal to the control module.

Pressure transmitter: monitor the pressure change of the washing machine in real time and convert it into a standard signal and output it to the control module.

High-pressure cleaners are generally divided into two types, which are divided into hot water and cold water, but the pressure of hot water high-pressure cleaners we commonly use is generally not higher than 250bar. Hot-water high-pressure cleaners are mainly used to clean difficult to wash Dirt and hot water high-pressure cleaners are heated by expanded tubes. When water passes through the expanded tubes, the pressure of the expanded tubes will be relatively large. If the bearing capacity of the expanded tubes does not increase, the pressure of the hot-water high-pressure cleaners will also increase. Does not increase. However, if the pressure of the expanded pipe is increased, the cost will also increase. Therefore, the working pressure of hot water pressure washer will be about 200 BAR. When high pressure is used, high pressure cold water washer is usually used to achieve the cleaning effect. When cleaning oil and various stubborn stains, Use hot water pressure washer or saturated steam washer.
