  • Optimizing centrifugal pump operation ScienceDirect

    Centrifugal pump operation is more than switching the pump on and directing the discharge flow to the required delivery point. This holds true even when a control valve is installed in the discharge line for the purpose of flow or level control. A few very essential operating guidelines must be adhered to if early bearing or.

  • What Is the Purpose of a Flow Switch? . Sciencing

    Apr 25, 2017 . A flow switch is a device that monitors the flow of air, steam or liquid. It sends a "trip signal" to a different device in the system, such as a pump. The flow switch can indicate to the pump to shut off or to turn on. Some of the general uses are for pump protection, for cooling circuit protection and alarms for too.

    Perhaps the most common use of centrifugal switches is within single phase, split phase induction motors. Here, the switch is used to disconnect the starting winding of the motor once the motor approaches its normal operating speed. In this case, the centrifugal switch consists of weights mounted to the shaft of the motor.
