QY充油式潛水泵(beng) 深井泵(beng) 農田灌溉泵(beng)電(dian)動(dong)機為充油密封結構，內腔充滿絕(jue)緣(yuan)潤滑油。能保(bao)持電(dian)動(dong)機內腔油壓(ya)大于外部(bu)水壓(ya)，阻止機外水進入(ru)電(dian)動(dong)機內部(bu)。

油浸式潛水泵 農用(yong)灌溉泵噴淋泵 電動(dong)(dong)機(ji)為(wei)充(chong)(chong)油密封結構，內(nei)腔充(chong)(chong)滿(man)絕(jue)(jue)緣(yuan)潤滑(hua)油。軸伸端(duan)裝有機(ji)械密封，既能防止外部水分(fen)和(he)潮氣進入電動(dong)(dong)機(ji)內(nei)腔，又熊阻(zu)止機(ji)內(nei)絕(jue)(jue)緣(yuan)潤滑(hua)油的外泄。

QY型充(chong)(chong)油式(shi)潛水(shui)電(dian)(dian)泵為泵機(ji)合一的可移式(shi)淺水(shui)排灌設(she)備，它的特點是電(dian)(dian)機(ji)內(nei)(nei)部充(chong)(chong)滿機(ji)械油，使(shi)機(ji)械密封的工作條件改善(shan)，外(wai)界的水(shui)更不(bu)易進入電(dian)(dian)動(dong)機(ji)內(nei)(nei)部。
