化工离心泵的安装技巧： 1.化工离心泵的安装技术关键在于确定化工离心泵安装高度(即吸程)。这个高度是指水源水面到化工离心泵叶轮中心线的垂直距离，它与允许吸上真空高度不能混为一谈，化工离心泵产品说明书或铭牌上标示的允许吸上真空高度是指化工离心泵进水口断面上的真空值，而且是在1标准大气压下、水温20摄氏度情况下，进行试验而测定得的。它并没有考虑吸水管道配套以后的水流状况。而化工离心泵安装高度应该是允许吸上真空高度扣除了吸水管道损失扬程以后，所剩下的那部分数值，它要克服实际地形吸水高度。化工离心泵安装高度不能超过计算值，否则，化工离心泵将会抽不上水来。 2.影响计算值的大小是吸水管道的阻力损失扬程，因此，宜采用最短的管路布置，并尽量少装弯头等配件，也可考虑适当配大一些口径的水管，以减管内流速。 3.应当指出，化工离心泵安装地点的高程和水温不同于试验条件时，如当地海拔300米以上或被抽水的水温超过20摄氏度，则计算值要进行修正。即不同海拔高程处的大气压力和高于20摄氏度水温时的饱和蒸汽压力。但是，水温为20摄氏度以下时，饱和蒸汽压力可忽略不计。 4.从管道安装技术上，吸水管道要求有严格的密封性，不能漏气、漏水，否则将会破坏化工离心泵进水口处的真空度，使化工离心泵出水量减少，严重时甚至抽不上水来。因此，要认真地做好管道的接口工作，保证管道连接的施工质量。

Chemical centrifugal pump installation tips: (1) chemical centrifugal pump installation key is to determine the chemical centrifugal pump mounting height (Suction). This height means the vertical distance of the centerline of the water surface to chemical centrifugal pump impeller, it is not be confused with the high vacuum allows the suction chemical centrifugal pump product manual or nameplate allows the vacuum suction on the height refers to the chemical centrifugal pump inlet section vacuum value, and is a standard atmospheric pressure, water temperature 20 ° C case, the test determination obtained. It does not take into account the flow of the suction pipe supporting. The chemical centrifugal pump mounting height should allow suction, high vacuum net loss of lift of the suction pipe, the rest part of the value, to overcome the actual terrain is highly absorbent. Chemical centrifugal pump mounting height can not exceed the calculated value, otherwise, chemical centrifugal pump will be pumping the Sheung Shui to (2) the size of the calculated values ​​is the head of the resistance loss of the suction pipe, therefore, should adopt the shortest piping layout and minimize the loaded elbow and other accessories can also be appropriately equipped with larger diameter pipe to less pipe flow rate. (3) It should be noted that the chemical centrifugal pump installation site elevation and the water temperature is different from the test conditions, such as local elevation of 300 meters above or pumping the water temperature exceeds 20 degrees Celsius, then the calculated values ​​to be amended. Elevation at atmospheric pressure and higher than 20 degrees Celsius water temperature, the saturated vapor pressure. However, the water temperature is below 20 ° C, the saturated vapor pressure can be negligible. From the pipeline installation technology, suction pipes require stringent tightness, can not leak, leaking, it will be the destruction of chemical centrifugal pump water inlet vacuum, chemical centrifugal pump out water to reduce, even when serious pumping Sheung Shui. Therefore, to carefully work out the interface of the pipeline, to ensure the quality of the construction of pipe connections.
