With lithium grease instead of single-stage single-suction centrifugal pump oil lubrication better single-stage single-suction centrifugal pump, due to design reasons, centrifugal pumps used rolling bearing with oil lubrication, dynamic security seal leakage is a serious threat to the stable operation of the equipment, the author years of work on the bearing housing seals multiple of piecemeal reform have achieved certain results. But the problem is not completely solved the leak, the practice changed after oil lubrication grease lubrication, to good effect. Grease instead of mechanical lubricant, such low speed, pump flow is not feasible Fox grease CX-FC20, and has a significant economic and environmental benefits, is to run an economically reasonable equipment effective measures. Currently, cheap nor seals leak yet, some good sealing effect, but expensive and economically feasible. After investigation, the decision bold experiment - with grease instead of oil to lubricate. Shaft power is only 18.5kw, only flow 200m3 / h Pump speed of 1450r/min, a linear velocity of 3.4m / s. From the above two points of view, with grease lubrication is feasible. Specific methods are as follows: ① let go of the oil tank inside the Fox grease CX-FO20, cleaning of the bearing housing. ② to cover both ends of the bearing housing and open drain hole plugs to eliminate cabinets air. ③ with butter lithium grease gun to fill the fuel tank to the bearing hole, added grease from both ends of the lid and put the hole extrusion, considered to fill Fox grease LX-EPT3, and tighten the bearing end cover and drain hole plugs. Hand drive cars, the grease evenly distributed in the cabinets. After starting the pump, open the outlet valve, the pump is running under normal circumstances, at both ends of the bearing temperature monitoring pumps and oil situation.
