    分析：在(zai)區分自吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)和增壓(ya)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)之前，必須要(yao)對自吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)和增壓(ya)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)定義重(zhong)復一(yi)下。所謂自吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)就是(shi)(shi)指第一(yi)次(ci)灌水后(hou)(hou)，以(yi)(yi)后(hou)(hou)再使用就無需再次(ci)灌水即可(ke)啟動運行(xing)，自吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)是(shi)(shi)否(fou)自吸(xi)(xi)(xi)要(yao)看停機后(hou)(hou)葉輪是(shi)(shi)否(fou)浸入水中，自吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)就是(shi)(shi)因為有獨特的(de)(de)(de)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)腔結構而可(ke)以(yi)(yi)保(bao)證(zheng)每(mei)次(ci)停機后(hou)(hou)葉輪都可(ke)以(yi)(yi)浸入水中才保(bao)證(zheng)了其自吸(xi)(xi)(xi);增壓(ya)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)是(shi)(shi)泛指能對管(guan)路的(de)(de)(de)液體進行(xing)提供額外壓(ya)力的(de)(de)(de)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)統稱，并不指某(mou)一(yi)種類型(xing)的(de)(de)(de)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)，增壓(ya)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)可(ke)以(yi)(yi)是(shi)(shi)管(guan)道泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)、離心泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)、污水泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)、自吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)、多級泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)等(deng)類型(xing)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)。如果(guo)要(yao)讓非自吸(xi)(xi)(xi)式的(de)(de)(de)增壓(ya)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)達到自吸(xi)(xi)(xi)效果(guo)(泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)位于水池(chi)上方)，可(ke)以(yi)(yi)在(zai)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)吸(xi)(xi)(xi)入口加裝底閥即可(ke)。
