The working conditions do not exceed the index, the load is not exceeded. Daily time is conducive to perception, look at the appearance, listen to the sound, touch the vibration, smell the taste, do a good job of cleaning the appearance of the work. When the pump is not in use for a long time, the pump should be taken apart. 2 Wipe the parts clean, oil to maintain good. The improvement of the stability of the medium-open pump group needs to be combined with the previous three aspects, so that the stability can be improved in an all-round way, and good results are obtained. When using the pump in the use of a lot of equipment, they are how to install can be very good with the operation of the open pump? Now mainly talk about the water ring vacuum pump supporting the installation. Because for the horizontal open pump to suck on the way of operation, pump domestic demand filled with media to operate, and fill the medium is through the operation of the vacuum pump, the quality of the vacuum pump by the vacuum pump manufacturers to decide, but for the vacuum pump has been bought back. 4 we can only and can only ensure that it works well in terms of installation and maintenance. Therefore, we need to follow the following points to maintain a good vacuum pump.

運行數據：出口直徑：DN=80～800mm流量：50～11600m3/h(額定點)揚程：H＝7.6～200m(額定點)許用工作壓力：≤2.5MPa許用試驗壓力：≤3.75MPa介質：清水或物理化學性質類似于清水的其它液體(固體顆粒≤80mg/L)。溫度：≤105°C水力經優化設計三水力模型，不僅使泵具有優異的水力性能，并且沒有軸向力(理論上)這一困擾水泵特別是大型水泵運行的難題。泵體、泵蓋、葉輪經精密鑄造，過流表面光滑提高了泵的抗汽蝕性能和效率。密封根據輸送介質或用戶要求采用填料密封或機械密封，不受轉向限制。對于填料密封，有足夠的空間用于更換填料。jdhuiquan4.13

When the open pump reaches full speed operation, it is necessary to carefully check: (1) Pay attention to the pump import and export pressure, with the export gate valve adjustment so that its pressure control in the specified range. (2) Whether the bearing is overheating, the ideal temperature for bearing operation is 40~60℃, and the temperature rise does not exceed 35 ℃. If the temperature is stable and does not rise again, it may be slightly above the above range, but more than 80 ℃ must not be allowed. If more than 80 ℃, the bearing body shall be fitted with cooling water. Filler leakage water is dripping appropriate (about 30 drops per minute). After the pump starts with a wrench to adjust the filler cover nut tightening to adjust the leakage amount, in order to meet the leakage requirements. (4) Keep track of the operation on a regular basis. Pipeline Installation Steps: (1) After the installation of the equipment, joints, discharge pipes and valves, do not use the pump as a pipe and valve support, require adequate attention to make the pipe and valve weight and excessive tightening force, etc. do not affect the pump body. Installation accessories should also be taken care to avoid allowing the pump to withstand any external force. To reduce head loss.

產品概述：S、SA系列雙吸中開泵，主要供輸送溫度不高于105°C的清水或理化性質類似于水的液體。適用于自來水廠、泵站、電站、空調循環用水、采暖用熱水循環、工業供水系統、消防系統、船舶、煉油工業(一般性液體)等輸送液體的場合。

產品特點：

1、內置式密封潤滑結構：泵內置式密封潤滑結構，密封循環水對泵密封系統的潤滑、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，內置式密封潤滑結構使泵整體結構渾然一體，靈活的結構設計使泵更加精美大方。  

3、率：采用CFD計算流體動力學，分析計算出泵內壓力分布和速度分布關系、優化泵的流道設計，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。軸為全封結構，確保了不與介質接觸，不銹蝕，使用壽命長。  

6、雙蝸殼：高揚程泵采用雙蝸殼結構，減輕了徑向力。

When installed during the anti-rust guarantee period of the pump, it is not disassembly and washing. Cleaning should be removed when abnormal or exceeding the anti-rust guarantee period, and should meet the following requirements: The disassembly order of parts and components should be in accordance with the requirements of manufacturers; parts and components should be free of rust, often cleaned and qualified, their mating surface should be coated with a thin layer of lubricating oil; Pump leveling and search should be carried out according to the installation instructions provided by the manufacturer. The steam separator shall be installed in accordance with the following requirements: The installation level deviation is not greater than 1/1000, the pipe connected with the pump should not be too long, the flange bonding surface should be tight, the water inlet hole of the soda separator should be connected with the external water supply pipe, and the pipeline should be kept open. Pump commissioning should meet the following requirements: The car should be flexible, no block, vacuum control valve should be adjusted to the appropriate opening, pump filler function of the cooling pipe should be smooth, should be injected into the pump body water, the car rinse clean.

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。根據泵殼承受的壓力，泵體和泵蓋材質采用灰口鑄鐵(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。
