3寸柴油機水(shui)(shui)(shui)(shui)(shui)泵(beng)YT30DPH自吸(xi)泵(beng)吸(xi)不(bu)(bu)上(shang)水(shui)(shui)(shui)(shui)(shui)原因：或是底閥關閉不(bu)(bu)嚴(yan)(yan)灌(guan)引水(shui)(shui)(shui)(shui)(shui)不(bu)(bu)滿、真空(kong)泵(beng)填(tian)料嚴(yan)(yan)重漏(lou)氣(qi)，閘閥或拍門關閉不(bu)(bu)嚴(yan)(yan)。這種情況應首先檢(jian)查(cha)水(shui)(shui)(shui)(shui)(shui)泵(beng)的密(mi)封，檢(jian)查(cha)時應先拔(ba)下電(dian)(dian)(dian)源插(cha)頭，用手堵住吸(xi)水(shui)(shui)(shui)(shui)(shui)口，把水(shui)(shui)(shui)(shui)(shui)泵(beng)灌(guan)滿水(shui)(shui)(shui)(shui)(shui)，用嘴銜住出口使勁(jing)往里吹氣(qi)，觀察(cha)泵(beng)頭是否漏(lou)水(shui)(shui)(shui)(shui)(shui)，漏(lou)水(shui)(shui)(shui)(shui)(shui)之處也就是密(mi)封損壞之處。問(wen)題：機殼帶電(dian)(dian)(dian)。多數是水(shui)(shui)(shui)(shui)(shui)封損壞，水(shui)(shui)(shui)(shui)(shui)通過電(dian)(dian)(dian)機軸滲入電(dian)(dian)(dian)機內使電(dian)(dian)(dian)機絕緣性能惡(e)化(hua)所致，可采用更換(huan)水(shui)(shui)(shui)(shui)(shui)封、烘干電(dian)(dian)(dian)機等方法修復
3寸高揚程(cheng)柴(chai)油(you)機水(shui)(shui)(shui)泵YT30DPH管路(lu)漏水(shui)(shui)(shui)或(huo)漏氣。可能安裝時螺帽擰得不緊(jin)。若滲漏不嚴重,可在漏氣或(huo)漏水(shui)(shui)(shui)的(de)(de)地方涂抹水(shui)(shui)(shui)泥(ni),或(huo)涂用瀝青油(you)拌(ban)和的(de)(de)水(shui)(shui)(shui)泥(ni)漿。常見的(de)(de)故(gu)障部位有吸水(shui)(shui)(shui)口(kou)墊、出水(shui)(shui)(shui)口(kou)墊、葉(xie)輪(lun)蓋墊，維修(xiu)時應更換。若無滿水(shui)(shui)(shui)現象(xiang)，多是葉(xie)輪(lun)損壞、吸水(shui)(shui)(shui)室(shi)和出水(shui)(shui)(shui)室(shi)之間的(de)(de)擋(dang)水(shui)(shui)(shui)內隔(ge)蝕穿、泵頭擋(dang)水(shui)(shui)(shui)隔(ge)磨平、葉(xie)輪(lun)和泵殼的(de)(de)間隙增大等，應更換葉(xie)輪(lun)和泵殼。
