礦山，城市給排水，電站，農(nóng)田排灌及各種水利工程。S系列中開泵工作原理：1，許用工作壓力為，即泵入口壓力+泵揚(yáng)程≤。根據(jù)泵殼承受的zui大壓力，泵體和泵蓋材質(zhì)采用灰口鑄()。介質(zhì)：溫度≤105℃的清水或物理化學(xué)性質(zhì)類似清水的其它液體(固體顆粒80mg/L)。采用油脂潤滑的封閉式滾動軸承，維護(hù)簡單，運(yùn)行時(shí)間長。(2)，配備恒定油位的油杯，也可用稀油潤滑。(3)，中開泵選用進(jìn)口(SKF，NSK，NTN)高質(zhì)量軸承，運(yùn)行平穩(wěn)，澡音低，使用壽命長。結(jié)構(gòu)緊湊，穩(wěn)定性好。該型泵為泵殼中開結(jié)構(gòu)，進(jìn)出口均在泵體上，檢修時(shí)只需吊出泵蓋，轉(zhuǎn)子部件便可移出進(jìn)行檢修作業(yè)，而不需拆卸管路，十分方便。根據(jù)需要電動機(jī)(驅(qū)動機(jī))可以在左端也可在右端。

本系列泵是單級、雙吸、水平中開式離心泵，適用于汲送清水和無腐蝕性的液體。介質(zhì)溫度80℃。軸承體通人冷卻水后，可輸送130℃以下的熱水。改變密封環(huán)、軸套和葉輪的材質(zhì)，可以輸送含有泥沙的渾水。改變承壓零件的材質(zhì)，可以提高泵的進(jìn)口壓力.泵的軸封一般采用軟填料密封，如有特殊要求，也可改裝機(jī)械密封。從電機(jī)方向看泵，泵為逆時(shí)針旋轉(zhuǎn)，按用戶要求，也可改為順時(shí)針旋轉(zhuǎn)。jdhuiquan4.13

Thus the centrifugal force is generated, under the b of centrifugal force, the liquid is dumped along the Blade Runner to the impeller outlet, and the liquid is collected and fed into the discharge tube through the worm shell. The liquid obtains energy from the impeller, increasing the pressure energy and speed energy, and relies on this energy to transport the liquid to the place of work. When an impeller does not allow the liquid to obtain sufficient energy, multiple impellers can be used in series or in parallel to work on the fluid. At the same time that the liquid is dumped to the impeller outlet, a low pressure is bed at the center of the impeller Inlet, and the pressure difference is generated between the liquid in the suction tank and the center of the impeller, and the liquid in the suction tank is continuously operated into the impeller under the b of this pressure difference. In this way, the impeller in the rotation process, one side of the constant liquid, while constantly giving the liquid with a certain amount of energy, the liquid discharge, so that the centrifugal pump work continuously. The medium-open pump is mainly composed of pump body, pump cover, sealing ring and rotor parts. Rotor parts are mainly composed of shafts and impeller mounted on the shaft, impeller retaining sleeve.

根據(jù)水泵行業(yè)規(guī)定，Sh型與S型兩大系列中開泵并存，直至統(tǒng)一設(shè)計(jì)出新型泵代替這兩個(gè)系列時(shí)為止。本產(chǎn)品主要用于工廠、礦山、城市、電站給水農(nóng)用排澇灌溉、各種水利工程用泵和采暖空調(diào)系統(tǒng)等場合

[二]性能范圍：
流量Q112m3/h-6460m3/h,揚(yáng)程H9m-140m，允許進(jìn)口壓力≤0.3Mpa(用戶在訂貨時(shí)須標(biāo)明進(jìn)口壓力值)。
