High-temperature oil pump is a positive displacement pump, work rely on the main, driven gear intermeshing changes in the volume of work to transport the melt. Its structure and performance make it widely used in different industries and promotion, to withstand high temperatures, with good sealing performance at high temperatures, the pump industry is a major leap in technology. But in the actual operation of how to maintain the high temperature pump it? Here we do a few analysis: High temperature pump routine maintenance (l) pump disintegration and cleaning, heating, cooling, starting and stopping should be strictly in accordance with the provisions of the operation, in order to avoid undue losses. (2) Care should be taken to maintain the stability of the population pressure of the booster pump so that it has a stable volumetric efficiency in favor of the pump itself and the stability of the downstream spinning quality. (3) The population is negative pressure of the 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. (4) to check the temperature of the heat medium jacket, the main body and the front and back cover of the heat medium temperature to be consistent. (5) Every time the output increases, it is necessary to record the output, speed, output, inlet pressure and current value at the time, and compare the data before and after, and carefully analyze them so as to find the anomalies as soon as possible and deal with them in time.
