High-temperature gear pump routine maintenance

Routine maintenance of high temperature gear pump (â… ) high temperature gear pump disassembly and cleaning, heating, cooling, starting and stopping should be strictly in accordance with the provisions of the operation to avoid unnecessary losses. (II) Care should be taken to maintain the population pressure of the booster pump stable and to have a stable volumetric efficiency to facilitate the pump itself and the stability of the downstream spinning quality. (â…¢) The population of negative pressure packing shaft seal pump, packing should be kept at a pressure higher than the atmospheric pressure. When the back pressure is reduced, the pressure of the stuffing box should be adjusted in time, otherwise the pump will be sucked into the air and the belt will be broken. This will affect the pelletizing and cause the discharge of the pelletizer. (IV) To regularly check the temperature of the heat medium jacket, the main body and front and back cover of the heat medium temperature to be consistent. (V) Each time the output is increased, it is necessary to record the output, speed, output, inlet pressure and current value at that time, and compare the data before and after, and carefully analyze them so as to find the anomaly and handle it in time as soon as possible.
