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.
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(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(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(yōu)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。

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.
