Again good water pump, if do not maintain, also cannot achieve higher efficiency, so we should pay attention to in the process of using centrifugal pump of some basic requirements below for you to meet the requirements of the centrifugal pump stop running after 1 centrifugal pump should be shut down after stop the inlet valve of the pump, to pump again after cooling, in turn, close the subsidiary system of heat pump valve 2 parking should be governed by the provisions of the equipment technical documents, should be each partial 20 30 min after stop turning half a circle until the pump body temperature down to 50 3When the cryogenic pump stops, when there is no special requirement, the pump should always be filled with liquid;Suction valve and discharge valve should be kept normally open;Adopts double mechanical seal of pump in low temperature, liquid level controller and sealing liquid pump seal cavity should maintain pump grouting pressure conveying crystallizable 4, easy solidified, easily medium such as precipitation of centrifugal pump, after stopping the pump should prevent blockage, and rinse with water or other medium in time of pump and pipeline inside 5 discharge pump deposited liquid, prevent rust and frost crack centrifugal pump can be widely used in electric power, metallurgy building materials industry such as coal conveying slurry containing solid particles

再好的水泵，如果不维护的话，也达不到更高的效率，所以在使用离心泵的过程中我们要注意一些基本的要求。下面为你介绍离心泵停止运转后的要求。

　　1、离心泵停止运转后应关闭泵的入口阀门，待泵冷却后再依次关闭附属系统的阀门。

　　2、高温泵停车应按设备技术文件的规定执行，停车后应每偏20一30min盘车半圈直到泵体温度降至50℃为止。

　　3、低温泵停车时，当无特殊要求时，泵内应经常充满液体;吸入阀和排出阀应保持常开状态;采用双端面机械密封的低温泵，液位控制器和泵密封腔内的密封液应保持泵的灌浆压力。

　　4、输送易结晶，易凝固，易沉淀等介质的离心泵，停泵后应防止堵塞，并及时用清水或其他介质冲洗泵和管道。

　　5、排出泵内积存的液体，防止锈蚀和冻裂。

　　离心泵可广泛用于电力、冶金、煤炭、建材等行业输送含有固体颗粒的浆体。
