Shanxi mine ventilator fan circle can be divided according to their service: ① main fan: for the whole mine or mine a jump (district) ventilation fan. ② Auxiliary Shanxi fan: for mine ventilation air duct and some branch network, the emperor to help work the main fan, fan manufacturers to ensure that the branch of the required wind t auxiliary fan. ③ local Shanxi fan: for mine ventilation local sites, such as single head Tunneling of Shandong Factory ventilation, air pressure it generates all of its connections to overcome wind resistance reduction. Shanxi fan pressure based. Blower fan can be divided into low, medium and high pressure air blower. In the standard intake condition, the main fan size divided by its total pressure ① ② low pressure and medium pressure main fan Main Fan: 1000Pa cross-flow fan cross-flow fan is a small high-pressure centrifugal fan to the front with a multi-blade impeller . Gas enters the outer edge of the impeller rotor from one side, then the other side through the impeller exhaust ventilation Factory in Xinjiang, the gas in the impeller blades twice by force. Performance under the same conditions as Pax ventilation Factory, its small size, low speed. Compared with other types of low-speed fan, cross-flow fan has a higher efficiency. Its axial width can be arbitrarily selected, without affecting the state of the gas flow, the gas over the entire width of the rotor remains uniform flow. It is a long narrow outlet section, suitable for mounting or ventilation for cooling the flat-shaped in the various devices.
