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，如果不維護的話(huà)，也達不到更高的效率，所以在使用離心泵的過(guò)程中我們要注意一些基本的要求。下面為你介紹離心泵停止運轉后的要求。

　　1、離心泵停止運轉后應關(guān)閉泵的入口閥門(mén)，待泵冷卻后再依次關(guān)閉附屬系統的閥門(mén)。

　　2、高溫泵停車(chē)應按設備技術(shù)文件的規定執行，停車(chē)后應每偏20一30min盤(pán)車(chē)半圈直到泵體溫度降至50℃為止。

　　3、低溫泵停車(chē)時(shí)，當無(wú)特殊要求時(shí)，泵內應經(jīng)常充滿(mǎn)液體;吸入閥和排出閥應保持常開(kāi)狀態(tài);采用雙端面機械密封的低溫泵，液位控制器和泵密封腔內的密封液應保持泵的灌漿壓力。

　　4、輸送易結晶，易凝固，易沉淀等介質(zhì)的離心泵，停泵后應防止堵塞，并及時(shí)用清水或其他介質(zhì)沖洗泵和管道。

　　5、排出泵內積存的液體，防止銹蝕和凍裂。

　　離心泵可廣泛用于電力、冶金、煤炭、建材等行業(yè)輸送含有固體顆粒的漿體。
