How to operate and switch the circulating argon pump in the air separation process flow
Thread Content
For example, there are currently two circulating argon pumps, one in use and one as a backup. How does one switch to the backup pump now? It will not affect normal operation either.
Start the standby pump: two people are assigned – one to open the outlet valve of the standby pump and the other to close the outlet valve of the pump that is currently in operation. The operator on site reports the flow rate in real time, and the two people adjust the speed of the valves accordingly to ensure a smooth transition between pumps. It is necessary to ensure that the pump that is in operation is completely shut off and that the outlet valve of the standby pump is fully open
There’s no flow~ There’s only the pressure at the outlet here~ Also, does this argon pump have backflow? Is the backup pump return fully open? Then turn it off slowly?
