Under the conditions of Shanxi fan calibration samples given sample based on fan performance parameters to select fan model. In the choice of Shanxi fan, you should try to avoid using the fan to work in parallel or in series. When Yuncheng joint working jiaocheng saving ventilator fan, shall - Diego fans choose to work in parallel or series of the same model specifications; When used in series, the first stage to the second stage of wind turbine should ask certain pipeline linking . Request to have the muffler ventilation system fan, you should first consider the low-noise fan, such as high efficiency impeller peripheral speed -M, and make it work at maximum efficiency point; we will take appropriate measures in the text of water cooling fan silencer such as the installation of special equipment muffler. Cross-flow fan cross flow fan is multi-blade impeller centrifugal fan to the front with a small high pressure. Gas enters from the side of the outer edge of the impeller rotor mine ventilator stone floor, and then the other side is discharged through the impeller, the role of gas twice by the force of the blade in the impeller. Under the same performance conditions, 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.
