Easy to understand, take you to understand the high pressure fan!
Release time:2016-01-22
Under the design conditions, fans with a wind pressure of 30kPa-200KPa or a compression ratio e = 1.3-3 belong to the category of high-pressure fans. At present, air ring vacuum pumps are generally classified as high-pressure fans in the industry. These proper nouns are listed in a row, but it's confusing. These complicated statements are not easy to understand, so let us explain some related knowledge about high-pressure fans with easy-to-understand words below Zibo Yinfeng Fan Co., Ltd.
When the impeller rotates, the vane causes the gas to move forward and outward due to the centrifugal force, thereby forming a series of spiral motions. The air between the blades of the impeller accelerates in a spiral shape and squeezes the gas outside the pump body (inhaled through the suction port) into the side groove. When it enters the side channel, the gas is compressed and then returns to the space between the blades Speed up rotation.
High pressure fan is also a type of fan, also called high pressure blower, which is different from general centrifugal high pressure blower. The working principle of the fan is basically the same as that of the turbine compressor, but because the gas flow rate is low and the pressure does not change much, it is generally not necessary to consider the change of the specific volume of the gas, that is, the gas is treated as an incompressible fluid. According to the direction of gas flow, it is divided into centrifugal, axial flow, diagonal flow (mixed flow) and cross flow types. Centrifugal fans are more common.
High pressure fans are widely used in filling machinery, hospital conveying systems, combustion deaerators, cigarette filter forming machines, atomizing dryers, etc. 9-19, 9-12, 9-09 ventilators produced by our company 9 -19 high pressure centrifugal fan ventilator is generally used in forging furnaces and high pressure forced ventilation, and can be widely used for conveying materials, air and non-corrosive and unnatural, non-sticky gas. It can also be designed, selected according to customer needs, ordered by samples, and designed and manufactured by other machinery.
Serving customers is the guideline and improving customer satisfaction is the goal. Our induced draft fans have been on the road.
