潜水电泵的构(gou)造QJ型(xing)(xing)潜(qian)水(shui)(shui)电(dian)(dian)(dian)(dian)泵主要由QJ型(xing)(xing)潜(qian)水(shui)(shui)泵和(he)YQS型(xing)(xing)潜(qian)水(shui)(shui)电(dian)(dian)(dian)(dian)机(ji)(ji)两部分(fen)组成。QJ型(xing)(xing)潜(qian)水(shui)(shui)电(dian)(dian)(dian)(dian)泵的泵体(ti)(ti)位于电(dian)(dian)(dian)(dian)动机(ji)(ji)上端，叶(ye)轮为(wei)离心式(shi)，轴承(cheng)用(yong)(yong)水(shui)(shui)润(run)滑橡胶轴承(cheng)，泵与电(dian)(dian)(dian)(dian)动机(ji)(ji)轴用(yong)(yong)联(lian)轴器刚性联(lian)接。在水(shui)(shui)泵上端设有(you)逆止(zhi)阀体(ti)(ti)，用(yong)(yong)来防止(zhi)水(shui)(shui)泵停运时(shi)，因水(shui)(shui)倒流引(yin)起(qi)(qi)潜(qian)水(shui)(shui)电(dian)(dian)(dian)(dian)泵反(fan)转。YQS型(xing)(xing)潜(qian)水(shui)(shui)电(dian)(dian)(dian)(dian)机(ji)(ji)定绕(rao)组采(cai)用(yong)(yong)聚乙(yi)烯绝缘尼龙护套(tao)电(dian)(dian)(dian)(dian)磁线(xian)。电(dian)(dian)(dian)(dian)机(ji)(ji)腔(qiang)内充满洁净的清(qing)水(shui)(shui)，用(yong)(yong)以冷却电(dian)(dian)(dian)(dian)机(ji)(ji)和(he)润(run)滑辆承(cheng)，电(dian)(dian)(dian)(dian)机(ji)(ji)内部的橡皮调压(ya)膜可以调整因电(dian)(dian)(dian)(dian)机(ji)(ji)温度(du)升高引(yin)起(qi)(qi)的机(ji)(ji)体(ti)(ti)内清(qing)水(shui)(shui)的胀缩压(ya)差，电(dian)(dian)(dian)(dian)机(ji)(ji)的上端轴上装(zhuang)有(you)由甩砂环和(he)二个反(fan)向安装(zhuang)的防砂器，防止(zhi)水(shui)(shui)中泥砂进(jin)入机(ji)(ji)体(ti)(ti)内部。

安装前(qian)的(de)准(zhun)备工作(zuo)由于电泵(beng)轴承采用水(shui)(shui)润滑(hua)材(cai)质，因此不可(ke)脱水(shui)(shui)运(yun)转(zhuan)(zhuan)。即使在(zai)起动电机的(de)短时间里也(ye)要避免(mian)(mian)干运(yun)转(zhuan)(zhuan)，以免(mian)(mian)损(sun)(sun)坏泵(beng)的(de)轴承。电机部分的(de)检(jian)查(cha)(cha)(cha)：电机在(zai)下(xia)井前(qian)，应检(jian)查(cha)(cha)(cha)其装配质量(liang)(liang)是(shi)否(fou)(fou)(fou)(fou)(fou)良好，紧固件有无(wu)松动现象(xiang)，电缆有无(wu)破损(sun)(sun)，电源(yuan)和电气装置是(shi)否(fou)(fou)(fou)(fou)(fou)可(ke)靠(kao)。电源(yuan)的(de)电压、频率是(shi)否(fou)(fou)(fou)(fou)(fou)和铭牌相符；检(jian)查(cha)(cha)(cha)电机轴的(de)转(zhuan)(zhuan)动是(shi)否(fou)(fou)(fou)(fou)(fou)灵活(huo)。以及运(yun)输(shu)途中有无(wu)损(sun)(sun)伤，泵(beng)轴转(zhuan)(zhuan)动是(shi)否(fou)(fou)(fou)(fou)(fou)灵活(huo)，轴向窄量(liang)(liang)是(shi)否(fou)(fou)(fou)(fou)(fou)达到要求，逆(ni)止(zhi)阀(fa)是(shi)否(fou)(fou)(fou)(fou)(fou)动作(zuo)。水(shui)(shui)泵(beng)放(fang)入水(shui)(shui)井前(qian)，须用洁净清水(shui)(shui)（不含沙）注满电机。
