During the first 3-4 hours of high temperature heat-conducting oil pump in operation, turn off the oil pump after heating the equipment to the operating temperature, check the coaxiality of the pump shaft and the motor shaft coupling, and the deviation between the pump shaft and the motor shaft should be controlled within the allowable range The pump shaft should be light and flexible and rotate without vibration if it is turned by hand. If the hot oil pump fails to meet the above requirements, it should be adjusted again;

When the ball bearing on the impeller side is installed, the side of the high temperature heat transfer oil pump with the dust cover should be installed facing the impeller, and the heat transfer oil should be injected before driving. Type centrifugal pump, when the bearing is reinstalled, the side of the hot oil pump with the dust cover should also be installed facing the impeller side, and filled with grease during installation.

After 3000 hours of operation for each ball bearing, it must be removed and cleaned with diesel, and inspected for damage. If it is damaged, it must be replaced with a new bearing.
