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 820 years of work in the Fox special grease 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, and has a significant economic and environmental benefits, economic rationality is to make the device run an effective measure. 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 in the tank, 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, and tighten the bearing cap 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. Lubricants Caution: 1, different grades, grade lubricants prohibit mix. If you must mix, should do miscibility experiments. If you can not make use of the first week after the discovery of high temperature and check the oil filter found a foreign body special grease, replace the oil filter properly. Describes two oil reacts to greatly shorten the oil life. 2, must be exhausted when replacing the old oil. Prohibited the use of additional or filtration and reuse approach. Because although the color of the surface oil unchanged, but the additive consumption may have exceeded the limit. 3, if not more sludge (sludge from how much can be stopped after the injection hole to check with the wand and gas cylinder), into 2/3 of the new oil after running 15-60 minutes or even a couple of Liberating the net, and then filled New oil and running. If too much carbon sludge, oil barrel detachable special grease Fox WSP5000, with a special cleaning agent, even with the manual removal of sludge and carbon deposits, but the oil barrel cleaning the 后福斯 825 special grease, then add Jog sludge coke cleaning agent, so that the whole system is full of cleaning agents, soak 3-8 hours, let go of pollutants. After adding new oil washing operation from 100 to 200 hours, put the net to clean oil, and finally adding new oil and running. 4, when oil change while changing the oil bypass filters, oil filters, oil and gas separation fine filter, coarse filter filter elements, etc., check collection filter, air filter, check valve, temperature alarm, and so is intact .
