What are the differences between axial fan guide vanes and impellers? And what about the hydraulic vane adjustment?. How do you do it?.
The guide vane is divided into front leaves and guide blade and impeller on the front or rear, front leaves produced in the air in the rotating impeller inlet guide vane, the gas outlet of the impeller after rectification discharge, I see are generally the latter, impeller is mainly on the gas power, gas pressure and has a certain speed. You said that the hydraulic blade adjustment is adjusting the installation angle of the blade, the blast it seems only Shen
The blade of centrifugal pump impeller is generally backward curved blade. The blade has two kinds of cylindrical and twisted forms, and the twisted blade can reduce the load of the blade, and can improve the suction performance of the centrifugal pump and improve the anti cavitation ability, but the manufacture is difficult and the cost is higher.
Open impellerOnly blade and blade stiffener, impeller without front and rear cover (open impeller blade less than 2-5). Impeller efficiency is low, the application is less, mainly used for conveying high viscosity liquid, as well as slurry liquid.
Axial fan is the same direction as the axis of the wind (that is, the direction of the wind and the axis parallel), such as electric fans, air conditioners, fans, that is, axial flow fan.Also called the local fan axial fan is a fan used in industrial and mining enterprises, it is different from the general fan and its motor and fan blades are in a cylinder shape is in a cylinder shape, for local ventilation, convenient installation, ventilation effect, safety, can in the wind duct sent to the designated area.
