1, routine maintenance (l) pump disintegration and cleaning, heating, cooling, starting and stopping should be strictly in accordance with the provisions of the operation to avoid unnecessary 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 lead to 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 abnormalities as soon as possible and deal with them in time.
2, high temperature gear pump common faults and countermeasures are as follows:
(1) Failure phenomenon: the pump can not discharge Fault causes: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, no inlet or pressure is too low; d, viscosity is too high, the pump can not bite countermeasures: a , Confirm the direction of rotation; b, confirm whether the valve is closed; c, check the valve and pressure gauge; d, check the liquid viscosity, low-speed operation according to the speed ratio of the flow appears, if the flow, then the inflow.
(2) Symptom: insufficient pump flow Failure causes: a, suction or discharge valve is closed; b, the inlet pressure is low; c, the outlet pipe plugging; d, packing box leak; e, low speed Countermeasures: a, confirm whether the valve Closed; b, check the valve is open; c, to confirm the discharge volume is normal; d, tighten; a large number of leaks affect production, should stop running, demolition inspection;
