How to solve the problem of heat conduction oil pump vibration: 1, the pump shaft and motor are not the same. Solution: Adjust the pump and motor center axis. 2, motor bearing damage. The solution: the pump and motor separation, respectively, try to determine the pump vibration or motor vibration, if the motor vibration, it may be motor bearing damage, replacement can be. 3, thermal oil pump bearing damage. The solution: the bearing seat is provided with two ball bearings, by the heat pump oil pump impeller side of the ball bearing with the heat transfer oil lubrication, by the coupling side of a ball bearing is lubricated with high temperature grease: each Ball bearings running 3000 hours, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the new bearing. 4, there is air in the pipeline. Solution: adjust the installation location of the pipeline. Remove the air from the pipeline.
