How to determine the mechanical diaphragm size size

Today, Xiaobian continue to introduce mechanical diaphragm pump, then we want to know is how to determine the size of mechanical diaphragm pump size. Some people will find it very hard. In fact, there are fixed steps. Just like formulating formulas, as long as we follow the steps, there should not be any problems. The specific methods are as follows: How to determine the size of the mechanical diaphragm pump Diaphragm selection and determination of mechanical diaphragm pump mainly based on the flow capacity of the valve Cv. In a variety of engineering instrument design and selection, the mechanical diaphragm pump Cv calculations, and mechanical diaphragm pump design specifications. Calculate the caliber from Cv to determine the valve, the general need to go through the following steps: 1, to determine the calculation of flow: According to the existing production capacity, equipment load and medium conditions, calculate the flow Qmax and Qmin. 2, before and after the valve to determine the pressure difference: According to the selected valve flow characteristics and system characteristics selected S (resistance coefficient), and then determine the pressure differential. 3, Calculate Cv: According to the adjusted medium to choose the appropriate formula and chart Cmax and Cmin. 4, choose Cv: According to Cmax, select the product standard series selected> Cmax and its closest level C. 5, the mechanical diaphragm pump opening checking: the general requirements of the maximum flow rate calculation when the opening â‰¯ 90%, the minimum flow calculation when the opening â‰® 10%. 6, mechanical diaphragm pump actually adjustable ratio checking: the general requirements of the actual adjustable ratio â‰® 10. 7, Seat diameter and nominal diameter to determine: After verification of appropriate, according to C to determine. The above is the mechanical diaphragm how to determine the size of the general steps, we understand? Here, Xiaobian particularly note the meaning of the following several symbols, max, min, respectively, on behalf of the largest, smallest, â‰¯, â‰® represent less than or equal to, greater than or equal to. Do not get rid of them mean. Further Reading: IFAT China Guangzhou exhibition industry leader in building water pump manufacturers ranking article belongs to Internet industry (Xiamen) Co., Ltd.

Short section is a kind of fittings commonly used in industrial pipeline connection. There are common thread nipples, which are divided into two heads, outer silk, single head outer silk, flat head and outer silk, and some short joints with flanges.

The short section is divided into tubing short section and casing short section. The flanging short section in the pipe fittings is popular with the flange. The flange is set in the flanges, then the tail and the steel pipe are welded. At this time, the flange can be moved. As long as the flange is connected to the flange at any time, the flange can be connected.
The tubing short section is a short tubing. Compared with the tubing, it is only of different lengths and the others are the same. The lengths are: 0.25m, 0.5m, 1M, 1.5m, etc., which are used to match the downhole string.
