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.

运行数据：出口直径：DN=80～800mm流量：50～11600m3/h(额定点)扬程：H＝7.6～200m(额定点)许用工作压力：≤2.5MPa许用试验压力：≤3.75MPa介质：清水或物理化学性质类似于清水的其它液体(固体颗粒≤80mg/L)。温度：≤105°C水力经优化设计三水力模型，不仅使泵具有优异的水力性能，并且没有轴向力(理论上)这一困扰水泵特别是大型水泵运行的难题。泵体、泵盖、叶轮经精密铸造，过流表面光滑提高了泵的抗汽蚀性能和效率。密封根据输送介质或用户要求采用填料密封或机械密封，不受转向限制。对于填料密封，有足够的空间用于更换填料。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.

产品概述：S、SA系列双吸中开泵，主要供输送温度不高于105°C的清水或理化性质类似于水的液体。适用于自来水厂、泵站、电站、空调循环用水、采暖用热水循环、工业供水系统、消防系统、船舶、炼油工业(一般性液体)等输送液体的场合。

产品特点：

1、内置式密封润滑结构：泵内置式密封润滑结构，密封循环水对泵密封系统的润滑、冲洗更为直接、有效。  

2、外形美观：直线型的外观并在泵盖上附加强筋，内置式密封润滑结构使泵整体结构浑然一体，灵活的结构设计使泵更加精美大方。  

3、率：采用CFD计算流体动力学，分析计算出泵内压力分布和速度分布关系、优化泵的流道设计，确保泵有的水力形线，提高了泵的效率。泵体采用双流道设计，以减小径向力。泵体、泵盖、叶轮等过流部采用树脂砂板模造型，保证了外观及流道尺寸以及泵的水力效率。S、SA系列双吸中开泵效率比一般双吸泵高3～5％。  

4、平衡精度高：转子部件动平衡精度为G1。0级。  

5、轴：轴短且刚性好，增加轴径，以延长轴承和机械密封的使用寿命。轴为全封结构，确保了不与介质接触，不锈蚀，使用寿命长。  

6、双蜗壳：高扬程泵采用双蜗壳结构，减轻了径向力。

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.

工作条件：

1．许用工作压力为2.5MPa；即泵入口压力+泵扬程≤2.5MPa。根据泵壳承受的压力，泵体和泵盖材质采用灰口铸铁(1.6MPa)、球墨铸铁(2.0MPa)、铸钢(2.5MPa)。在订货时敬请注明泵的承压情况或材质。
