Troubleshooting and inspection requirements for high voltage pump.

After each high-pressure pump is used, flush the hose and residual liquid in the nozzle with clean water, and clean the casing. After cleaning the power supply, put the power in a fixed place. If there is any damage or pressure, please mark "maintenance required" and inform the maintenance personnel before use. The maintenance worker is responsible for the maintenance of the high-pressure pump, check the operation of the high-pressure pump every day and make records. If the seal is damaged, the aging will cause air leakage and the pressure will not rise, it shall be replaced in time. The high-pressure pump motor shall be checked once every half a year. The main engine and main contactor switch shall be checked. Lubricant shall be added if necessary to ensure correct use and record.

In the operation of high pressure pump, the method to eliminate the problem is that the water gun does not spray water, the pressure is insufficient and the water gun shakes. Causes and Countermeasures: because of low water supply pressure or no water supply pressure, water inlet and nozzle are blocked, sand particles in water cause pressure of regulating valve too large, resulting in blocking of heating coil. The inlet filter has been damaged for a long time. Foreign matters enter the check valve, the pump body is frozen and ceramic plunger is frozen; the cleaner tank is free of water, open the hydraulic plunger oil pump switch, the pump seal is broken, and the bypass valve is blocked, which leads to the failure of automatic heating stop system. Heat up the coil.

The hand pump heating system will not fire or damage. The causes and Countermeasures: check the oil level of the oil tank, whether the diesel engine filter is blocked, whether the connection between the diesel pump and the motor is disconnected, whether the diesel pump is damaged, and check whether the solenoid valve is blocked or damaged. Confirm that the temperature switch is damaged and the nozzle is blocked. Check the high voltage cable package for damage. Whether the gap between fire plugs is too large, whether the spark is too weak, whether the fuel quality is unqualified, whether ash accumulation blocks the air circulation, whether the pressure switch is damaged, whether the air inlet matches, and whether the heating coil is damaged. High voltage plunger pump is widely used in high voltage, high flow and high flow rate occasions.
