High-temperature gear pump routine maintenance First, high temperature gear pump should pay attention to cleaning, heating, cooling, starting and stopping pumps should be strictly in accordance with the provisions of the operation to avoid unnecessary losses. Second, pay attention to keep the pump inlet pressure stability, it has a stable volumetric efficiency, in favor of the pump itself. Third, the inlet pressure of the packing shaft seal pump, packing pressure should be maintained at a pressure higher than the outside 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. Fourth, we should always check the temperature of the heat medium jacket, the main body and front and back cover of the heat medium temperature to be consistent. Fifth, every time the output increases, the current output, speed, out, inlet pressure, current value recorded, and before and after the data to be compared, careful analysis, in order to detect anomalies as soon as possible, in a timely manner.
