1) The pump that is newly put into use must be replaced with grease (oil) after 100 hours of operation, and then replaced once every 500 hours.
2) Lubricating grease-lubricated flow bearings should be replaced after 1500 hours of operation. The amount of oil to be filled should not be too much or too little, because too much or too little grease will cause the bearing to heat up. 1/2~2/3 of the bearing chamber volume is suitable.
3) For bearings lubricated with lubricating oil, the amount of oil should be added to the specified position.
4) The container containing lubricating oil or grease should be clean and should be sealed properly. There should be no dust, iron filings and other debris to avoid damage to the bearing.
5) Motor bearings generally use sodium-based grease, which is characterized by high temperature resistance (125 ° C), but is easily soluble in water, so it can not be used for lubrication of water pump bearings.
