What is the function of the heating pump system for the water pump design?
Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.
As the feed water temperature is higher, in the case of non warm pump start, will make the pump body is subject to greater thermal impact; in addition, the flow components with the pump contact heating fast, not contact with water directly heating slowly. This expansion due to uneven speed, it will inevitably produce thermal stress, deformation of the pump body, sealing surface, the joint surface is lax and leaking phenomenon. Therefore, the warm water pump system is designed for the water pump.
As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"
