- How to prevent the fire pump cavitation? | ZJBetter
- 2020.08.14
- How to prevent the fire pump cavitation? First, from the perspective of prevention, we recommend to open the recirculation pipe when the feed water flow is reduced to a certain extent, so that a part of the feed water flow will return to the deaerator, then there will be enough water in the pump to pass the pump. carry away the heat generated by the friction, keep at a certain temperature from rising to vaporize the feed water.
