High-pressure gear pump is cleaned with kerosene brush to keep the cleanliness of gear pump as far as possible.

Maintain the stability of inlet pressure of pressurized high-pressure gear pump, so that high-pressure gear pump has a stable volume efficiency, in order to facilitate the operation of high-pressure gear pump itself and mechanical stability.

Every time the output is increased, the output, speed, outlet, inlet pressure and current should be recorded, and the data should be compared and analyzed carefully so as to find abnormalities as soon as possible and deal with them in time.

It is necessary to change the oil to the prescribed oil level according to the season.

The temperature of the heat medium jacket should be checked regularly, and the temperature of the main body and the front and rear cover should be kept the same.

Common faults and Countermeasures of high temperature gear and high pressure gear pump:

Fault Phenomenon: Reasons for Failure of High Pressure Gear Pump Layout

1. Inhalation or discharge valves are closed.

2. The inlet is unexpected or the pressure is too low.

3. High viscosity, high pressure gear pump can not bite countermeasure.

3. Verify the direction of rotation, whether the valve is closed, check the valve and pressure gauge.

4. Check the liquid viscosity to see if the flow rate at low speed is proportional to the speed. If there is flow rate, the flow will be insufficient.

Fault Phenomenon: Reasons for Flow Insufficiency of High Pressure Gear Pump

1. The suction or discharge valves are closed, the inlet pressure is low, and the outlet pipeline is blocked.

2. Before pressing into the self-tightening oil seal, a layer of lubricant should be coated on the surface, paying attention to the orientation of the edge, and not reversing.

3. Packing box leakage, low speed countermeasures, confirm whether the valve is closed, check whether the valve is open.

4. Verify whether the discharge is normal.

5. Tightening, a large number of leaks affecting production, should stop operation, disassembly and inspection.

6. Check the actual speed of high-pressure gear pump shaft.
