The reason why the temperature of the self-priming pump bearing is too high is probably due to the insufficient lubricating oil of the external lubricating oil system or the addition of the wrong lubricating oil. For example, the ZW self-priming sewage pump product adopts the connection mode in the form of a coupling. Bearing lubricants need to be added to the bearing housing to lubricate the bearings.
The original self-priming pump factory is filled with solid lubricating butter, and some users add liquid oil without authorization to cause the bearing to heat up, and the liquid oil that is injected will leak out. Adding the wrong lubricant is also the reason why the self-priming pump bearing temperature is too high.
Another possibility is that the user does not install the pump shaft and the motor shaft in the reassembly process after replacing the coupling and disassembling the self-priming pump. It may also be caused by the user not purchasing the motor during the self-installation process. The solution to this type of self-priming pump bearing temperature is too high to correct the concentricity of the pump shaft and the motor shaft.
