Street Washer Truck is a necessary tool for sanitation workers to clean the road. Washing the road manually is a waste of manpower and time, and the cleaning effect may not be ideal. In order to improve operational efficiency and reduce labor costs, Street Washer Truck  sanitation cleaning equipment was born.

Working principle of Street Washer Truck is first stored in a tank, the water through the pipe connected to the high pressure pump, with the engine power to the high pressure pump, the higher the engine speed, the pressure is higher, at this time will be ordinary water into high pressure low velocity of water, again through the high pressure pipe will give high pressure spray nozzle, high pressure low velocity water Because the aperture of the high-pressure nozzle is much smaller than the diameter of the high-pressure tube, the high-pressure nozzle will instantly turn the water with high pressure and low velocity into the jet water with low pressure and high velocity. The smaller the aperture of the nozzle, the farther the range of the water with low pressure and high velocity will be, and the greater the impact force will be.

The following problems should be paid attention to when the Street Washer Truck is operating:

I. High pressure cleaning operation

1. After the cleaning car runs to the operation area, the vehicle stops, the transmission is in neutral position, the hand brake is pulled up, and the warning sound is turned on.

2. When using the manual spray gun, stop the operation, turn on the water pump switch, and connect the quick connector of the spray gun. The operator first opens the switch of the spray gun, and then rotates the switch of the water pump to the "working" position, and the spray gun starts to work.

3. When you stop working, loosen the spray gun switch first, and then turn off the water pump switch. When a spray gun is needed to wash the car, in order to reduce the water pressure, the rotational speed of the secondary engine can be appropriately reduced.

4. Notes for the hydraulic system: check whether there is oil leakage and oil leakage at the sealing place and joint before operation, otherwise replace the sealing ring; Check the filter in the tank for filth every six months.
