How to maintain the pump bearings

Pump bearing maintenance methods: 1, motor bearings generally use sodium-based grease, this grease is characterized by high temperature (125 ℃), but easily soluble in water, it can not be used for pump bearing lubrication. 2, Sheng lubricating oil or grease containers to be clean, usually should be sealed, there should be no dust, iron filings and other debris, so as not to damage the bearings. 3, the use of grease lubrication of the flow of bearings, running 1500 hours, should be replaced by grease, filling the oil can not be too much or too little, because too much or too little grease can cause bearing fever, the amount of fuel generally in the Bearing chamber volume of 1/2 ~ 2/3 is appropriate. 4, for the use of lubricated bearings, oil should be added to the specified location. 5, newly put into use the pump, usually after 100 hours of operation to be replaced grease (oil), after every 500 hours of operation to replace 1.
