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.
產(chǎn)品概述：S、SA系列雙吸中開泵，主要供輸送溫度不高于105°C的清水或理化性質(zhì)類似于水的液體。適用于自來水廠、泵站、電站、空調(diào)循環(huán)用水、采暖用熱水循環(huán)、工業(yè)供水系統(tǒng)、消防系統(tǒng)、船舶、煉油工業(yè)(一般性液體)等輸送液體的場合。
產(chǎn)品特點：
1、內(nèi)置式密封潤滑結(jié)構(gòu)：泵內(nèi)置式密封潤滑結(jié)構(gòu)，密封循環(huán)水對泵密封系統(tǒng)的潤滑、沖洗更為直接、有效。
2、外形美觀：直線型的外觀并在泵蓋上附加強筋，內(nèi)置式密封潤滑結(jié)構(gòu)使泵整體結(jié)構(gòu)渾然一體，靈活的結(jié)構(gòu)設(shè)計使泵更加精美大方。
3、率：采用CFD計算流體動力學(xué)，分析計算出泵內(nèi)壓力分布和速度分布關(guān)系、優(yōu)化泵的流道設(shè)計，確保泵有的水力形線，提高了泵的效率。泵體采用雙流道設(shè)計，以減小徑向力。泵體、泵蓋、葉輪等過流部采用樹脂砂板模造型，保證了外觀及流道尺寸以及泵的水力效率。S、SA系列雙吸中開泵效率比一般雙吸泵高3～5％。
4、平衡精度高：轉(zhuǎn)子部件動平衡精度為G1。0級。
5、軸：軸短且剛性好，增加軸徑，以延長軸承和機械密封的使用壽命。軸為全封結(jié)構(gòu)，確保了不與介質(zhì)接觸，不銹蝕，使用壽命長。
6、雙蝸殼：高揚程泵采用雙蝸殼結(jié)構(gòu)，減輕了徑向力。

Side can be started. Pump commissioning should meet the following requirements: The pump should be in the specified speed and operating range of operation, continuous commissioning time should not be less than 30min, the pump water supply should be normal, water temperature and water supply pressure should be in line with the requirements of the manufacturer; The temperature rise of the bearing should not be higher than 30 ℃, and the connection should be strict. 4 No leakage phenomenon, there should be no abnormal sound and vibration in operation, after the commissioning, should be released in the pump water, and then use water to rinse the pump clean. S series of open pumps can be basically supplied to factories, cities, power stations, water conservancy projects and so on can be used as drainage or feed pumps, but also for farmland irrigation. For the transport of water without solid particles or physical, chemical properties similar to water other liquids, the transmission of the medium temperature of 0℃~80℃, allowing the import pressure. In the water treatment industry, the S-series Open pump is an extremely important equipment. The Operation safety of the open pump in the S series directly affects the normal operation of the water treatment process.
工作條件：
1．許用工作壓力為2.5MPa；即泵入口壓力+泵揚程≤2.5MPa。根據(jù)泵殼承受的壓力，泵體和泵蓋材質(zhì)采用灰口鑄鐵(1.6MPa)、球墨鑄鐵(2.0MPa)、鑄鋼(2.5MPa)。在訂貨時敬請注明泵的承壓情況或材質(zhì)。
2．介質(zhì)：溫度≤105°C的清水或物理化學(xué)性質(zhì)類似清水的其它液體(固體顆?！?0mg/L)。 軸承1、采用油脂潤滑的封閉式滾動軸承，維護簡單，運行時間長；2、配備恒定油位的油杯，也可用稀油潤滑；
