Centrifugal pump cooled by circulating water
Thread Content
How do you start and stop a centrifugal pump cooled by circulating water?
Before starting the centrifugal pump, turn on the circulating water cooling first; turn it off after stopping the pump. Generally, circulating water cooling is kept in operation continuously.
The circulating water should be put into use first, and then the pump should be started. This circulating water is generally kept in operation; if your company has strict requirements, it should be activated when starting up and disconnected when shutting down
In the north, for indoor pumps, circulating water is used first before the pumps are activated； After stopping the pump, close the circulation water valve and open the vent valve ； For outdoor pumps, they are operated in the same way as indoor pumps during summer; in winter, to prevent freezing, the circulating water must be kept in use continuously.
Install a solenoid valve that turns on and off along with the pump.
It may seem luxurious on the surface, but it is energy-efficient. The electricity cost saved each year is enough to buy several of them.
Feed the circulating water first, and then start the pump. Insert it when in use, and remove it when not in use. They are usually kept on all the time. This is generally the case in our positions, but during winter, when anti-freezing measures are taken, the circulating water has to be disconnected from the pumps; all water stored in the system is drained to carry out anti-freezing treatment, and the connections are reestablished once the weather warms up. Hope this is useful to you, thank you!
