Ultra-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 The dirt and hot water pressure washer are heated by the expansion tube. When the water passes through the expansion tube, the pressure of the expansion tube will be relatively large. If the bearing capacity of the expansion tube does not increase, the pressure of the hot water pressure washer It will 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 pressure sprayer or saturated steam washer.
Electronic control system
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 work requirements, and used as a fault alarm.
After the pressure washers measurement data of the washing machine enters the control module, according to the increase or decrease of the number of water guns working on site, the output of the pump motor is automatically adjusted by the inverter 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.
