我國農村幅原廣闊，每年農村都需要大量的泵，一般來說農用泵占泵總產量一半以上。中開泵在建筑領域提供樓宇自動給排水，增壓鍋爐給水，疏竣，無負壓給水，暖通空調，消防設備及其它通用設備。電力領域提供灌溉，排水，引水工程，自來水工程，發電廠除灰，冷凝水，循環水，鍋爐供水等設備配套服務。臥式雙吸中開泵在環保領域中提供污水處理，綠化灌溉，引水，配水，土壤改良或排洪水等。中開泵主要適用于輸送不含固體顆粒的介質。因此這種泵可以在石油，化工以及電力等行業進行應用，比如說在石化中延遲焦化，火電廠中的中型鍋爐給水等。這種類型的泵在維護方面非常的方便，因此在相關的行業中得到了廣泛的應用。雙吸中開泵在水利。由于泵內的各種損失泵的有效功率總是小于軸功率。

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、軸套和葉輪的材質，可以輸送含有泥沙的渾水。改變承壓零件的材質，可以提高泵的進口壓力.泵的軸封一般采用軟填料密封，如有特殊要求，也可改裝機械密封。從電機方向看泵，泵為逆時針旋轉，按用戶要求，也可改為順時針旋轉。jdhuiquan4.13

If you spray oil outward, you should stop and check immediately. The purchase of mechanical seals at different prices has a significant impact on their quality. Take quality control measures mechanical seal before leaving the factory must do sealing performance test, and have a certificate. Mechanical seal after long-term operation, so that the dynamic ring and static ring wear, spring and shaft rust wear, sealant ring wear, aging, deformation, etc., can cause sealing leakage, must repair or replace new parts. The sealing surface of the dynamic ring and static ring shall not have cracks, corners, scratches, hemp points, flying edges and partial grinding, scratches, hemp points can not run through the entire sealing end surface. If the fixed static and dynamic ring is used, the height of the convex of the static and dynamic ring is not less than 3mm, and the height of a single convex is not less than lmm, so as not to affect the heat dissipation. 3 Dynamic ring After installation should be guaranteed to move flexibly on the shaft, the dynamic ring pressure on the spring should be able to bounce back freely, to maintain the vertical and parallel of the static and dynamic ring. Reasonable selection of medium-open pump, is to consider the pump unit and pumping station investment and operating costs, such as comprehensive technical and economic indicators.

根據水泵行業規定，Sh型與S型兩大系列中開泵并存，直至統一設計出新型泵代替這兩個系列時為止。本產品主要用于工廠、礦山、城市、電站給水農用排澇灌溉、各種水利工程用泵和采暖空調系統等場合
