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, the use of grease-lubricated flow bearings, after 1500 hours of operation, should be replaced with grease, the amount of oil can not be too much or too little, because too much or too little grease will cause bearing heat, the amount of fuel is generally in the The volume of the bearing chamber is preferably 1/2 to 2/3.
3. For bearings lubricated with lubricating oil, the amount of oil should be added to the specified position.
4, the container of lubricating oil or grease should be clean, should be sealed properly, there should be no dust, iron filings and other debris, so as not to damage the bearing 5, the motor bearing generally uses sodium-based grease, the characteristic of this grease is It can withstand high temperatures (125 ° C), but it is easy to dissolve in water, so it can not be used for lubrication of water pump bearings.
