Recently, Roots blower With its excellent intelligence, it is very popular in the market. More and more people want to buy Roots blowers, but many buyers do not know how to use it. So how should we operate the Roots blower? The definition of high-pressure Roots blower is under the design condition. The blower with air pressure of 30kPa~200KPa or compression ratio of e=1.3~3 belongs to the category of high-pressure Roots blower. At present, the air ring vacuum pump is generally classified as high-pressure Roots blower in the industry. High pressure Roots blower, also called high pressure blower, is different from general centrifugal blower fan. The selection of high pressure Roots blower is very complicated because it is widely used.
Generally speaking, the following two steps should be followed: 1. It is necessary to determine what function of high-pressure Roots blower is used on site, whether it is suction or blowing, and find out the corresponding pressure flow curve of high-pressure Roots blower; If you misread the curve, sometimes the selected products cannot be used;
2. According to the calculated pressure and flow, find the working curve above the working point that meets the pressure and flow at the same time on the curve chart; Then select the high-pressure fan model according to the working curve; As long as it is a different work site, its demand for pressure and flow is different. Therefore, to obtain relatively accurate data, it is necessary to carry out relevant calculations.
