The classification and principle of welding filter fan

Classification of welding dust catcher blower fan for welding filter, principle of action, pressure, production materials and the application scope is different, so the ventilator has many classification method. According to its in pipe network, the role of points, called the induced draft fan, in one of the suction blowing effect called a blower. According to its working principle, divided into centrifugal ventilator and axial flow fan and mixed flow fan. Mainly used in removing dust project application of the centrifugal fan. Fan pressure according to size, fan can be divided into low pressure ventilator ( p＜1000Pa) , medium pressure ventilator ( P is 1000 ~ 3000 pa) And the high pressure fan ( p＞3000Pa) Three, is most used in environmental engineering after two. According to the production materials, fan fan can be divided into steel, plastic fan, glass fiber reinforced plastic fan and stainless steel fan, etc. According to its application scope, the fan can be divided into dust exhausting fan, detoxification fan, boiler fan, exhaust fan and general fan, etc. Working principle of the ventilator welding welding filter filter fan is nuclear power flow into the air spinning machine total pressure ( Increased) The air is made of continuous flow driving mechanical energy conversion are realized by changing the fluid momentum air flows in the centrifugal fan. Impeller is installed inside the volute 4, when the impeller rotates, gas after 2 axial suction inlet, then gas about turning flows through the impeller blade of port 90. When gas through rotating impeller blade, due to the effect of blade gain energy, the gas pressure increase, the kinetic energy increases. And volute will round out the gas concentration, diversion, from the ventilator air outlet 6 7 discharge outlet diffuser. When the gas gain enough energy to overcome its resistance, it can send gas to higher ground or in the distance.
