The start and stop of the boiler pre-pump usually corresponds to the start and stop of the boiler feed water pump. When the boiler is started, the pre-pump is started first, and the main pump is started after the feed water pressure reaches the set value. When the boiler is stopped, the main pump is stopped first, and then the pre-pump is stopped. This start and stop method can ensure that the pressure at the inlet of the feed water pump is within the appropriate range to avoid cavitation. |
