500S98B中開泵長(zhǎng)沙廠家直銷，（長(zhǎng)沙東方工業(yè)泵廠 13755154094 qq475946464 0731-85018184李經(jīng)理）質(zhì)優(yōu)價(jià)廉，運(yùn)行平穩(wěn)，安全可靠，服務(wù)一流！
500S98B型號(hào)意義及參數(shù)：
500---代表吸入口徑:500mm,S---代表單級(jí)雙吸離心泵，B---代表葉輪經(jīng)過兩次切割，98---代表設(shè)計(jì)揚(yáng)程：98m，實(shí)際揚(yáng)程：74m，實(shí)際流量：1746m3/h，效率：78%，汽蝕余量：4.0m，葉輪直徑：745mm，軸功率：452KW，轉(zhuǎn)速：980r/min,電機(jī)功率：560KW，電機(jī)型號(hào)：Y5002-6，進(jìn)口口徑：500mm，出口口徑：300mm，泵重：3800Kg,除電機(jī)外，可配套閘閥、止回閥、底閥、進(jìn)出口法蘭片、控制柜、軟接頭、變徑（大小頭）、流量計(jì)、卡箍等。
500S98B型中開泵系列單級(jí)雙吸中開式離心泵(S型雙吸離心泵)結(jié)構(gòu)：S(SM、SF、SY)型單級(jí)雙吸離心泵為臥式安裝，吸入口和吐出口均在泵軸中心線下方，與泵軸線垂直，檢修時(shí)不需拆卸進(jìn)、出水管路，拿開泵蓋即可取出轉(zhuǎn)子部件，泵主要由泵體、泵蓋、葉輪、密封環(huán)、軸套、軸承等零部件組成，泵體與泵蓋構(gòu)成葉輪工作室，葉輪軸向力通過葉片對(duì)稱布置平衡。
500S98B軸 承：泵兩端為滾動(dòng)軸承支撐轉(zhuǎn)子部件，用油脂潤(rùn)滑，入口直徑太于700mm采用稀油潤(rùn)滑。
500S98B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，水泵均為逆吋針方向旋轉(zhuǎn)。如根據(jù)用戶特殊訂貨需要也可改為順吋針旋轉(zhuǎn)。
500S98B的主要另件有：泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。除軸的材料為優(yōu)質(zhì)碳素鋼外，其余多為鑄鐵制成。
500S98B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)出水法蘭的下部制有放水的管螺孔。
500S98B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。
500S98B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(rùn)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(rùn)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)小量高壓水通過水封管流入填料腔起水封作用。
