30、 Pump Maintenance 泵的维护保养 It is better for the plunger pump to work at 7080% of full horsepower, it can prolong the life of the pump. Before starting the pump, check the fluid level of power end lubricating box and fluid end packing lubricating box. Fulfill the oil if the oil is not enough and regula

31、te the oil pressure while the pump is running. Check the sealing performance of plungers. Add oil in time when the pump pauses. If the pumping fluid is turbid, it is suggested that after pumping job, the pump should pump clean water to clean the pump and discharge pipelines until the discharge water

32、 is clear. If the weather is very cold, the water stayed in the fluid end should be drain out. 柱塞泵在满功率7080%为宜，这样可以延长设备的使用寿命。 泵启动前应检查动力端润滑油箱油位及液力端盘根润滑油箱油位，油不够 时，及时加油，并在启动泵时调整其润滑油压；检查柱塞的密封度。泵停 机前，若泵送的介质混浊，建议工作结束之后，泵送清水以清洗泵及排出 管汇，直至水变清再停机；若天冷，应将泵头体内腔的积水排尽以防冻结。 Pump maintenances including: Daily mainten
