Twin screw pump maintenance and repair methods introduced
In the use of twin-screw pump, pay attention to routine maintenance and maintenance to ensure the life of the pump, in order to improve work efficiency. Xiao Bian to introduce the twin screw pump maintenance and care methods. Twin Screw Pump Twin Screw Pump Maintenance and Maintenance Method 1. Daily Maintenance and Maintenance 1.1 Check the oil level in the gear box (04) when the screw pump is stopped. If necessary, remove the filler plug (131) and fill it to the center of the oil gauge (106). 1.2 Listen to any abnormal noise and vibration. 1.3 Check pump for leaks during pump operation. Note: For mechanical seals, in the majority of cases, no leakage is observable from the seal drain due to vaporization, but sometimes small and consistent leaks are allowed. 2, weekly inspection and maintenance 2.1 For the pump has stopped working for more than a week, should open the inlet and outlet valves, connected to the motor power, move a few times the pump. 2.2 Check the inlet and outlet pipes on the valve can work properly. 3, quarterly maintenance and repair 3.1 Check all the nuts and compressors on the basis of the bolts are loose. 3.2 Installation regulations Gearbox oil is changed every March. Loosen the drain plug (130) of the gearbox (04) to release the gear oil. Tighten the drain plug, open the filler screw (131), fill with clean light oil, and clean the gearbox. After cleaning, open the drain plug, release the light oil, tighten the drain plug, inject the specified gear oil from the plug to the middle of the oil mark (106), and tighten the oil plug. 4, annual maintenance and inspection 4.1 check the coupling of the situation. 4.2 Check pump and motor nameplate values ​​for pump flow, pressure and power. If necessary, in the event of a significant drop in pressure and flow, the pump should be disassembled and replaced, and the damaged parts repaired. Of course, if the pump performance is still satisfactory, there is no need to dismantle the pump for repair. 5, twin-screw pump oil system manufacturers to replace the time 5.1 bearings to join once a month 3 # Universal lithium grease. 5.2 The new gear pump new 250 hours to replace Mobil 140 or Great Wall brand 150 vehicle gear oil; continuous operation every 1000 hours, replace the same car gear oil. 5.3 mechanical seal oil: to ensure that the oil level down in the center of the inspection hole, depending on the situation daily supplement, oil grade: ISO VG22-150VG28 (equivalent to 20 # oil), replaced once every six months.
