1, increase the heat preservation method for the high pressure washing car to prevent the high pressure pump, water pipes and waterways from freezing.
2. Empty the water in the pump of the temporarily unused high-pressure washing car, and empty the water in the water tank, water pipe and other waterway components. Tianjin high pressure pump drainage specific operation process is as follows: Close the high pressure inlet pipe (prevent water in the water tank from entering the high pressure pump) → remove the nozzle on the reel → start the high pressure pump (operating at idle speed) → Investigate the reel hose until no more water is coming out → Stop and close the high pressure pump → Open the three wire plugs under the hydraulic end of the high pressure pump (pump head), and push the slim rod about 15cm~20cm in length through the round hole of the device wire plug. Until there is a spring touch, there will be a little water out, repeated pushing several times until there is no more water out.
3. It is advocated that before stopping the use of the high pressure pump, non-corrosive antifreeze can be injected in the inlet direction, so that the pump head, high pressure pipe and other parts in contact with water are antifreeze to prevent freezing hazards.
4. When the high-pressure cleaning vehicle is not used, the high-pressure cleaning equipment is stored in the room at room temperature above 0 ° C to prevent freezing.
5. If ice is found in the water inlet pipe, the high pressure pump and the outlet pipe before using the high pressure cleaning vehicle, the high pressure pump shall not be started, nor shall it be frozen with boiling water, pouring, etc., to prevent the temperature difference from causing the equipment to crack, resulting in loss. It can be frozen with warm water, or the high-pressure cleaning equipment can be frozen at room temperature.
6, the water in the tank will show the state of ice water mixture (showing flocculent) when the external temperature drops to 0 ° C, at the moment the use of high pressure pump, ice water mixture will be attached to the filter network after the filter system of the water inlet pipe, resulting in a lack of water supply, Tianjin high pressure pump will show the phenomenon of hose fibrillation, need to be checked in advance to prevent the phenomenon of hose fibrillation.
7, the antifreeze and freezing of high pressure pipe can refer to the antifreeze and freezing method of high pressure cleaning pump.
8, the high pressure cleaning pump and accessories can be started after freezing, when stopping the use of the need to refer to the above anti-freezing measures.
9, high pressure cleaning equipment icing, will damage the seal in the high pressure pump to reduce the sealing function.
10, after the high pressure cleaning equipment is frozen, if the equipment is forcibly started, it will lead to the deformation and damage of the operating components such as the spring and valve cover in the hydraulic end of the high pressure pump, and then the phenomenon of rubber hose flutter. Severe will lead to high pressure pump power end cracking and other severe consequences.
