The most notable thing for fault repair of high pressure gear pump

The fault repair of the high pressure gear pump is as follows:

(l) Decomposition and cleaning of fault repair of high-pressure gear pump, lifting, cooling, starting and stopping should be strictly in accordance with the regulations to avoid undue losses.

(2) When each production increase, record the current output, speed, output, inlet pressure, and current value, and compare the data before and after, and analyze it carefully so that the abnormality can be detected as soon as possible and dealt with in time.

(3) Packing shaft seal pump with negative population pressure should keep the pressure at the stuffing box higher than the external atmospheric pressure. When the back pressure is reduced, the pressure of the stuffing box should be adjusted in time. Otherwise, the high-pressure gear pump will inhale the air, causing the strip to be broken, which will affect the pelletizing and cause the pelletizer to discharge.

(4) It should be noted that the pressure of the booster pump population is kept stable, so that it has a stable volumetric efficiency to facilitate the operation of the pump itself and the stability of the downstream spinning quality.

(5) Always check the temperature of the heat medium jacket of the high-pressure gear pump, and keep the temperature of the main body and the heat medium of the front and rear covers consistent.
