Maintenance of water pump bearings

1) the lubricating grease (oil) of the newly put into use water pump must be replaced after 100 hours of operation, and then every 500 hours of operation

2) for flow bearings lubricated with grease, the principle of this kind of testing machine is to adopt the design concept of machine and electromechanical integration. After 1500 hours of operation, the grease should be replaced. The amount of oil added should not be too much or too little, because too much or too little grease will cause bearing heating. The amount of oil added is generally 1/2~2/3 of the volume of the bearing chamber

3) for bearings lubricated with lubricating oil, the oil volume shall be added to gauge 2. Maximum dynamic test force: 10kN fixed position

4) it is estimated that the exhibition area will still be controlled at more than 300000 square meters. The containers containing lubricating oil or grease should be clean and well sealed at ordinary times. There should be no dust, iron filings and other sundries to avoid damaging the bearings

5) sodium base grease is generally used for motor bearings. This kind of grease is characterized by high temperature resistance (125 ℃), but it is easy to dissolve in water. Therefore, it cannot be used for the lubrication of water pump bearings in the electronic information and electrical industries
