What happens when a fire pump is idle? Will it affect the normal operation of the fire pump? The answer is that fire pump idling in a very short time will not cause damage (within 1 minute), long time idling will affect the fire pump. The following is my introduction to why the fire pump will idle and the hazards of fire pump idling.

Why the fire pump will idle phenomenon? It is very simple, the liquid in the fire pump is not enough or no liquid, is the so-called idling, then just analyze the reasons why the liquid will be insufficient, there are mainly the following points.
1, the import medium of the fire pump is not sufficient or the inlet pressure is not enough
2, fire pump inlet pipe blockage
3, the air in the fire pump cavity is not exhausted
When the fire pump is idling, the liquid can not be transported out normally, which is equivalent to doing useless work, there is no big impact for the click, but for the pump, the impact is still relatively big, and the serious situation will probably directly damage the pump. Here we analyze the fire pump idling will cause what kind of impact.
Idling fire pump is easy to cavitation, damage to the pump body and overflow parts.
Idle fire pump parts do not get liquid lubrication, resulting in dry wear, thus rapid damage; parts heat up, no liquid cooling by the role of thermal expansion and contraction of those narrow gap position (such as sealing ring) is easy to bite.
Some fire pumps have idle induction system, when the fire pump idle immediately alarm and automatic shutdown to protect the safety of the unit.
Science and technology is the basis for the continuous development of enterprises, zjbetter continue to provide quality products and services to customers, we look forward to win-win cooperation with you!
