The high temperature gear oil pump is suitable for conveying high temperature liquids without solid particles and fibers, non-corrosive, medium temperature up to 250 ° C, viscosity of 5-1500 cst. When the gear rotates, the melt enters the tooth groove of the two gears of the suction chamber. As the gear rotates, the melt is brought into the discharge chamber from both sides, and the gears are again meshed, so that the melt in the tooth groove is squeezed out. The chamber is pumped to the outlet pipe. As soon as the pump shaft rotates, the gear presses the melt toward the outlet side.
High temperature gear pump maintenance
(l) Disintegration and cleaning of the pump, rise and fall, start and stop should be strictly in accordance with the provisions to avoid undue losses.
(2) 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.
(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 pump will take in air, causing the strip to be broken, which will affect the pelletizing and cause the pelletizer to discharge.
(4) Always check the temperature of the heat medium jacket, and the temperature of the main body and the front and back covers should be the same.
(5) 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.
