原因是水泵體(ti)內(nei)有(you)空(kong)氣(qi)(qi)或(huo)(huo)進水(shui)(shui)(shui)管(guan)(guan)(guan)積氣(qi)(qi)，或(huo)(huo)是(shi)(shi)底閥關閉不嚴(yan)灌(guan)引水(shui)(shui)(shui)不滿(man)、真空(kong)泵(beng)(beng)(beng)填料嚴(yan)重(zhong)(zhong)漏(lou)(lou)(lou)(lou)氣(qi)(qi)，閘閥或(huo)(huo)拍門(men)關閉不嚴(yan)。排除方法：先把水(shui)(shui)(shui)壓上來(lai)，再將泵(beng)(beng)(beng)體(ti)注滿(man)水(shui)(shui)(shui)，然后開(kai)機。同時檢查(cha)逆止閥是(shi)(shi)否(fou)嚴(yan)密，管(guan)(guan)(guan)路(lu)、接頭(tou)有(you)無(wu)漏(lou)(lou)(lou)(lou)氣(qi)(qi)現(xian)象(xiang)，如(ru)發現(xian)漏(lou)(lou)(lou)(lou)氣(qi)(qi)，拆(chai)卸后在(zai)接頭(tou)處(chu)涂(tu)上潤滑油(you)或(huo)(huo)調合漆(qi)，并擰緊(jin)螺絲。檢查(cha)水(shui)(shui)(shui)泵(beng)(beng)(beng)軸的(de)油(you)封(feng)環，如(ru)磨(mo)損嚴(yan)重(zhong)(zhong)應更換(huan)新件。管(guan)(guan)(guan)路(lu)漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)或(huo)(huo)漏(lou)(lou)(lou)(lou)氣(qi)(qi)。可(ke)能安裝時螺帽擰得(de)不緊(jin)。若(ruo)滲漏(lou)(lou)(lou)(lou)不嚴(yan)重(zhong)(zhong),可(ke)在(zai)漏(lou)(lou)(lou)(lou)氣(qi)(qi)或(huo)(huo)漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)的(de)地方涂(tu)抹水(shui)(shui)(shui)泥,或(huo)(huo)涂(tu)用瀝(li)青(qing)油(you)拌(ban)和(he)的(de)水(shui)(shui)(shui)泥漿。臨時性的(de)修理可(ke)涂(tu)些濕泥或(huo)(huo)軟(ruan)肥皂(zao)。若(ruo)在(zai)接頭(tou)處(chu)漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui),則可(ke)用扳手(shou)擰緊(jin)螺帽,如(ru)漏(lou)(lou)(lou)(lou)水(shui)(shui)(shui)嚴(yan)重(zhong)(zhong)則需要重(zhong)(zhong)新拆(chai)裝，更換(huan)有(you)裂紋的(de)管(guan)(guan)(guan)子；降低揚(yang)程，將水(shui)(shui)(shui)泵(beng)(beng)(beng)的(de)管(guan)(guan)(guan)口(kou)壓入水(shui)(shui)(shui)下(xia)0.5m。
