串接式(shi)(shi)井(jing)用(yong)(yong)(yong)(yong)潜(qian)(qian)水(shui)泵(beng)(beng)(beng)电(dian)动(dong)(dong)机(ji)的(de)(de)(de)特(te)点的(de)(de)(de)功率(lv)一般要(yao)(yao)比(bi)单台井(jing)用(yong)(yong)(yong)(yong)潜(qian)(qian)水(shui)电(dian)动(dong)(dong)机(ji)的(de)(de)(de)功率(lv)提高很(hen)(hen)多,主要(yao)(yao)用(yong)(yong)(yong)(yong)来配高扬程(cheng)、大流量(liang)(liang)、大功率(lv)的(de)(de)(de)井(jing)用(yong)(yong)(yong)(yong)潜(qian)(qian)水(shui)泵(beng)(beng)(beng)使(shi)用(yong)(yong)(yong)(yong)。这(zhei)种(zhong)潜(qian)(qian)水(shui)泵(beng)(beng)(beng)由于扬程(cheng)很(hen)(hen)高、流量(liang)(liang)又很(hen)(hen)大,运行时产生的(de)(de)(de)轴向(xiang)推(tui)力很(hen)(hen)大,通常要(yao)(yao)比(bi)一般井(jing)用(yong)(yong)(yong)(yong)潜(qian)(qian)水(shui)泵(beng)(beng)(beng)的(de)(de)(de)轴向(xiang)推(tui)力提高50%~100%,有时甚至更高。因(yin)此,串接式(shi)(shi)井(jing)用(yong)(yong)(yong)(yong)潜(qian)(qian)水(shui)电(dian)动(dong)(dong)机(ji)的(de)(de)(de)止(zhi)推(tui)轴承(cheng)应能承(cheng)受(shou)很(hen)(hen)高的(de)(de)(de)轴向(xiang)力,要(yao)(yao)求长期(qi)运行时磨损(sun)量(liang)(liang)比(bi)较小,使(shi)用(yong)(yong)(yong)(yong)寿命比(bi)较长。串接式(shi)(shi)井(jing)用(yong)(yong)(yong)(yong)充(chong)(chong)水(shui)式(shi)(shi)潜(qian)(qian)水(shui)电(dian)动(dong)(dong)机(ji)的(de)(de)(de)水(shui)润滑止(zhi)推(tui)轴承(cheng)一般采用(yong)(yong)(yong)(yong)分块调心式(shi)(shi)结构,并在设计时考虑(lv)充(chong)(chong)分的(de)(de)(de)冷却,以尽量(liang)(liang)提高水(shui)润滑止(zhi)推(tui)轴承(cheng)的(de)(de)(de)承(cheng)载力,提高使(shi)用(yong)(yong)(yong)(yong)可靠性,延长使(shi)用(yong)(yong)(yong)(yong)寿命。
