Machine by using the material classification can be divided into several, such as steel fan (general fan), FRP fan, plastic fan, fan aluminum, stainless steel, etc. 2. Fan Fan classified according to the direction of gas flow can be divided into centrifugal, axial flow, mixed flow (Francis) and cross-flow and other types. 3. The fan according to the flow direction of the airflow into the impeller into: axial fans, centrifugal fans and mixed flow (Francis) fan. 4. fan use is divided into the push-local fan (hereinafter referred to as the push-fan) and flameproof motors placed runner outside or in the flow path, explosion-proof electric motor placed in the sealed chamber withdrawable local fan (hereinafter referred to as the extraction fan). 5. A fan in the form of a pressurized can be divided into single-stage, two-stage or multi-stage pressure fan. Such as 4-72 is a single stage pressure blower is a multi-stage pressure fan 6. Fan divided according to purpose can be divided into: axial fan, Francis fan, blower, roof fans, air-conditioning fan and so on. 7. Press the fan can be divided into low pressure turbine Yellowstone blower pressure fan, high pressure air. D. Daily review of the case can drip drip glib deformities, such as drops glib dirty mobilize screws can be removed and cleaned. Atmosphere through filters examine whether the daily review of the atmosphere filters dirty. As dirty atmosphere removable filter, unscrew the butterfly screw mother, removed the lid, and cleaned filter sponge. (Unloading dirt filter careful not to fall into the fan inside the lead plane) to review the operation of the fan triangle with a period of time, the triangle zone will be expanded. Then the flow generator to the end face of the nut gripping blower, mobile generators, triangle back for position and then tighten the nut tight flow generator housing, and pay attention to the generator pulley breeze machine pulley to be in the same stereo on. At the same time reviewing the two screws at the top of the pulley can loose as loose Keep live. Daily review of safety valve sensitive situation, please clean up the swap as insensitive to guarantee reliable opening and closing. Daily review of whether the oil spill, breathable and repair of local Wuhu swf blower, as useless repairs please tell manufacturers. Daily clearing fan room, maintain a clean, good ventilation. From time to time to review the functioning of the turbine and generators, as found the tone, when a measure is not abnormal to timely downtime. Two, SWF series mixed flow fan characteristics??? Centrifugal fan can be made of the right-handed and left-handed two types. Elevation from the motor side, clockwise rotation of the impeller fan coil, called the right rotary blower, counter-clockwise rotation, called L Working Principle? centrifugal fan is based on the principle of potential energy is converted to kinetic energy, the use of high-speed rotation of the impeller the gas to accelerate and then decelerate, change the flow of the kinetic energy into potential energy (pressure). In the single-stage centrifugal blower fan in Huainan gxf gas from the axial into the impeller, changing the gas flow through a radial impeller, and then into the diffuser. In the diffuser, the gas flow direction changes cause deceleration that the deceleration effect the kinetic energy is converted into pressure energy. Pressure increased mainly in impeller, diffuser happens next in the process. In the multi-stage centrifugal fan, the reflux stream allows the impeller to the next, resulting in a higher pressure.
