不可忽略對中開泵可靠性方面的要求，總之通過我們的努力要獲得一款效率高汽蝕性能好，運行可靠穩(wěn)定的好泵。中開泵主要適用于輸送不含固體顆粒的介質(zhì)。因此這種泵可以在石油，化工以及電力等行業(yè)進行應(yīng)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(guān)的行業(yè)中得到了廣泛的應(yīng)用。由于泵內(nèi)的各種損失泵的有效功率總是小于軸功率，故效率總是小于1的。目前國內(nèi)中開泵中多數(shù)型號的效率一般在70-80％左右，少數(shù)大流量型號的效率在90%左右。影響中開泵效率的主要原因在于泵內(nèi)存在的能量損失，這些損失主要是機械損失，水力損失和容積損失。機械損失主要是葉輪外表面與液體的磨擦損失（即圓盤摩擦損失）以及離心泵軸承。

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(zhuǎn)，按用戶要求，也可改為順時針旋轉(zhuǎn)。jdhuiquan4.13

In the event of a major failure, the entire water treatment process will be paralyzed, bringing great inconvenience to the people's lives and production. According to the current analysis of the operation of the pump in the S series, the common faults are: The impeller has been subjected to surface corrosion in the sewage for a long time, the early fatigue fracture of the blades, the wear of the pump body overflow parts, the bending of the pump shaft, the burnout of the motor and the bearing, etc. It is very important to study the operation Safety, through the research of this content, not only improve the safety of the pump, but also improve its service life. And in the process of water treatment work, the use of the system is often changed, if not in accordance with the needs to be met, will affect the normal operation of production, resulting in greater waste. In order to manage effectively, it is necessary to carry out remote monitoring and field control of production system, and in order to improve production efficiency and safety, it is also necessary to detect the key parts of the pump in the S series. Thus, the research of automatic control technology is an important technology development trend.

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)計出新型泵代替這兩個系列時為止。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
