Operation steps for bringing a condensate pump back into standby mode after maintenance is completed during turbine operation. ①The inspection and maintenance work is complete; the work order has been collected, and the safety measures have been removed ； ②Contact the electrical and thermal engineering staff to supply power to the motors and electric doors ； ③Slightly open the seal water valve ； ④Slightly open the vacuum release valve, and pay attention to monitoring changes in the unit’s vacuum level as well as ensuring that the operating pump runs steadily ； ⑤Slowly open the entrance door ； ⑥After checking that everything is normal, open the outlet door; make sure the pump does not rotate in reverse ； ⑦After a comprehensive inspection confirms normal operation, the interlock standby can be activated as needed.
(1) Check to confirm that the maintenance work on the condensate pump has been completed, that the work order has been collected, and that the maintenance site is clean with no debris； (2) Open the seal water valve of the maintenance pump ； (3) Open the cooling water valve of the maintenance pump ； (4) Slowly open the air extraction valve on the maintenance pump housing to check that a proper vacuum is established inside the pump ； (5) Open the inlet valve of the maintenance pump ； (6) Power on the pump motor for maintenance ； (7) Open the discharge valve of the maintenance pump ； (8) Insert the condensate pump interlock switch to restore the maintenance pump to standby mode.
