What is the role of the water pump design of the warm pump system?
(2) Since the feed water temperature is high, it is started in the absence of a warm pump, and the pump body is subjected to a large thermal shock. In addition, the flow-through member in contact with the pump is heated and the portion not in direct contact with water
In this case start the pump, inevitably to appear vibration, friction and so on.
Will cause some of the internal movement gap disappeared, the coupling center damage.
The upper part of the expansion of the lower part of the expansion of less, there is "cat arch back."
(1) due to higher water supply temperature, before the start if not fully warm pump, the pump temperature, uneven, there is the phenomenon of hot under the cool.
