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.

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。

S Series Open Pump is a large number of general-purpose machinery and equipment, it is widely used in petroleum, chemical, power bllurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, in the national economy occupies an important b. For this reason, the cavitation problem of the open pump in the S series refers to the pressure of the open pump at the entrance of the P1 equal to or less than the saturated vapor pressure PV of the liquid at the same temperature, the liquid vaporization, the bubble under high pressure, rapid condensation or rupture to produce a very high pressure, highly frequent impact, the pump body strong vibration and noise, And significant reduction in efficiency. Then, in the S series, the pump must reduce the cavitation allowance of the pump itself in order to prevent cavitation. There are several specific bs. Reduce the suction height or increase the height of the inversion, reduce the loss, for this reason, we can try to increase the pipe diameter, minimize the length of the pipeline, elbow and accessories, etc., the cavitation will increase during the operation of the medium open pump, so it is necessary to prevent the water from running under large flow for a long time.

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。

2．介质：温度≤105°C的清水或物理化学性质类似清水的其它液体(固体颗粒≤80mg/L)。 轴承1、采用油脂润滑的封闭式滚动轴承，维护简单，运行时间长；2、配备恒定油位的油杯，也可用稀油润滑；

3、选用进口(SKF、NSK、NTN)高质量轴承，运行平稳，噪音低，使用寿命长。 结构 结构紧凑、稳定性好。
