Extrusion pump fault repair matters most noteworthy
Extrusion pump fault repair as follows:
(l) extrusion pump failure disintegration maintenance and cleaning, heating and cooling, should be strictly in accordance with the start-stop operation, in order to avoid unnecessary losses.
(2) The increase in production every time, to the time of production, speed, the inlet pressure, record the current value and compare data before and after a careful analysis for early detection of abnormalities, timely manner.
(3) The population of the negative pressure pump seal packing, stuffing box should be kept at a pressure higher than the outside atmospheric pressure. Reduce back pressure, the pressure should be adjusted stuffing box, otherwise it would pump out of the intake air, causing the cast strip off the tape, the impact of pelletizing, resulting in releasing granulator.
(4) should pay attention to maintaining a stable population pressure booster pump, it has a stable volumetric efficiency, in order to help stabilize the operation of the pump itself and downstream spinning quality.
(5) out of the pump should always check the temperature of the heat medium jacket, body and front cover of the heat medium temperature should be consistent.
