Split Case Pump (other Centrifugal Pumps) Bearing Temperature Standard
Considering the ambient temperature of 40°C, the maximum operating temperature of the motor cannot exceed 120/130°C. The maximum bearing temperature is 95°C. Relevant standard requirements are as follows. 1. GB3215-82 4.4.1 ...
Common Causes of Split Case Pump Vibration
During the operation of split case pumps, unacceptable vibrations are not desired, as vibrations not only waste resources and energy, but also generate unnecessary noise, and even damage the pump, which can lead to serious accidents and damage. Common vib...
Precautions for Shutting-down & Switching Split Case Pump
Shutdown of the Split Case Pump 1. Slowly close the discharge valve until the flow reaches the minimum flow. 2. Cut off the power supply, stop the pump, and close the outlet valve. 3. When there is a minimum flow bypass pip...
Precautions for Starting Split Case Pump
