管道清水泵@房山管道清水泵@管道清水泵6寸口徑
At present, the solution is to regularly replace lubricating oil, wear parts and regular cleaning of the hydraulic cavity. Strict mid-open pump operating procedures. Pump start-up and parking should be strictly in accordance with the requirements of the operation. At the start, 0 output pump, when the pump outlet has a certain pressure, the voltage regulator can be filled with nitrogen. Avoid the diaphragm debation caused by nitrogen filling, prevent the diaphragm rupture, improve the pump output, to proceed slowly, when stopping the pump, should also slowly reduce the output of the pump. Focus on checking lubricant oil level, machine pump sound, outlet pressure, nitrogen buffer tank pressure and so on. Regular replacement of the pump body diaphragm, nitrogen buffer tank diaphragm, in order to effectively prevent the simultaneous damage of two pumps caused by the occurrence of catalyst suspension. The mechanical seal is also called the End seal, which produces the appropriate compb force on the contact surface of the rotating dynamic ring and static ring by the pressure of the spring and the sealing medium, so that the two ends are tightly fitted. The end side maintains a very thin layer of oil film, the media through the resistance is very large, to prevent liquid leakage.
本系列泵是單級(jí)、雙吸、水平中開(kāi)式離心泵，適用于汲送清水和無(wú)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

故效率總是小于1的。目前國(guó)內(nèi)中開(kāi)泵中多數(shù)型號(hào)的效率一般在70-80％左右，少數(shù)大流量型號(hào)的效率在90%左右。影響中開(kāi)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(jī)械損失，水力損失和容積損失。機(jī)械損失主要是葉輪外表面與液體的磨擦損失（即圓盤(pán)摩擦損失）以及離心泵軸承，軸封上的摩擦損失，水力損失主要是液體在泵內(nèi)運(yùn)動(dòng)速度和方向的變化引起的沖擊損失。中開(kāi)泵效率是指泵的有效功率和軸功率的比值旋渦損失等，液體與泵內(nèi)各流道壁面的磨擦損失以及液體運(yùn)動(dòng)的內(nèi)部磨擦損失，容積損失主要是泵內(nèi)高壓液體向低壓區(qū)泄露回流造成的損失，包括密封環(huán)泄漏損失，平衡機(jī)構(gòu)泄漏損失和級(jí)間泄漏損失。通過(guò)不同可以使中開(kāi)泵的效率和汽蝕性能得到很好的提升當(dāng)然在進(jìn)行效率和汽蝕性能改造的同時(shí)。
根據(jù)水泵行業(yè)規(guī)定，Sh型與S型兩大系列中開(kāi)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(chǎng)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)。
