What to do in case of pump trip? How to handle it? 1. The control room should immediately switch the pump outlet control valve to manual mode and close it to the minimum position. At the same time, balance the liquid levels in each tower in a timely manner, and inform the main controller to reduce the load as appropriate. 2. Promptly inform the personnel on site to start the pump or the backup pump, and notify the electrical workshop to conduct an immediate inspection and take action. 3. After the pump starts, the control room should slowly open the control valve in order to adjust the operating conditions as quickly as possible. 4. If the pump fails to start properly, contact the control room promptly to initiate shutdown procedures, and also contact the electrical workshop immediately to restore normal operation as soon as possible.

Taking the tripping of the circulating water pump as an example: 1) Close the operation switch of the auxiliary pump and pull the operation switch of the pump that has tripped. 2) Disconnect the interlock switch. 3) Quickly check whether the pump that has tripped is running in reverse; if so, close the outlet valve immediately. 4) Check the operation status of the auxiliary pump. 5) If the auxiliary pump does not start automatically, it should be started promptly. 6) If there is no auxiliary pump or the auxiliary pump trips again after starting, report to the shift supervisor and station manager immediately. 7) Contact the electrical staff to investigate the cause of the tripping.

1. Immediately check the standby pump and start it as soon as possible. 2. If the standby pump does not start properly, cut off the gas supply to prevent overpressure. 3. Inspect the pump that stopped operating as well as the standby pump; once they are in working order, start them again and reconnect the gas supply to establish solution circulation
