產(chǎn)品簡介
S SH型雙吸清水離心泵的吸入口與吐出口均在水泵軸心線下方，水平方向與軸線成垂直位置、泵殼中開，檢修時(shí)無需拆卸進(jìn)水，排出管路及電動(dòng)機(jī)(或其他原動(dòng)機(jī))從聯(lián)軸器向泵的方向看去，水泵均為逆時(shí)針方向旋轉(zhuǎn)。如根據(jù)用戶特殊訂貨需要也可改為順時(shí)針旋轉(zhuǎn)。本型泵的主要另件有：泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。除軸的材料為碳素鋼外，其馀多為鑄鐵制成。泵體與泵蓋構(gòu)成葉輪的工作室，在進(jìn)出水法蘭上制有安裝真空表和壓力表的管螺孔，進(jìn)出水法蘭的下吝降制有放水的管螺孔。葉輪經(jīng)過靜平衡校驗(yàn)，用軸套和兩側(cè)的軸套螺母固定，其軸向位置可以通過軸套螺母進(jìn)行調(diào)整，葉輪的軸向力利用其葉片的對(duì)稱布置達(dá)到平衡，可能還有一些剩馀軸向力則同軸端的軸承承受。泵軸由兩個(gè)單列向心球軸承支承，軸承裝在泵體兩端的軸承體內(nèi)，用黃油潤滑，雙吸密封環(huán)用以減少水泵壓水室的水漏回吸水室。水泵通過聯(lián)軸器由電動(dòng)機(jī)直接傳動(dòng)．軸封為軟填料密封，為了冷卻潤滑密封腔和防止空氣漏入泵內(nèi)，在填料之間有水封環(huán)，水泵工作時(shí)少量高壓水通過水封管流入填料腔起水封作用

SH型雙吸中開泵和S型雙吸中開泵對(duì)照表入下：
SH型泵及S型泵統(tǒng)稱為雙吸泵，其工作性能及配用電機(jī)大體相同。需要說明的是泵的旋轉(zhuǎn)方向不同，從電機(jī)端看SH型泵為逆時(shí)針旋轉(zhuǎn)，而S型泵則順時(shí)針。
