Question

Accepted Answer

Answering questions related to starting pump, two phase flow, control station work, ejector problem and troubleshooting, and vacuum in column.

To start a pump, ensure that the suction line is filled with liquid and open the discharge valve. Then, turn on the motor and gradually open the suction valve.
Two phase flow is when both liquid and gas are present in the pipe. This can cause issues with pump performance and require special considerations in design.
Control stations are used to monitor and control the operation of pumps and other equipment. They can include sensors, valves, and other components.
Ejector problems can include issues with clogging, low suction pressure, and poor performance. Troubleshooting may involve checking for blockages, adjusting operating parameters, or replacing components.
Vacuum is often used in distillation columns to lower the boiling point of the liquid being distilled and improve separation efficiency.
