Uses: Widely used in industrial and civil construction of ventilation and air conditioning systems. Particularly suitable for pressurized air supply pipe. SWF (A) [HLF] -Ⅰ type can replace the high-pressure axial fan SWF (A) [HLF] -Ⅱ double speed, a dual-purpose machine, SWF (A) [HLF] -Ⅲ type can replace high-pressure centrifugal fan ??? Structure and characteristics: The basic structure of the type of inlet and outlet on the same axis (ie axial structure), round shell as cones, leaves were ranged along the width of the flow shape. There are straight cylindrical type, drum-shaped and curved muffler plus three types of imports. The pneumatic Meridian acceleration principle, the fan has dual characteristics of centrifugal and axial flow, which both have large high pressure flow, and high efficiency, low noise and high efficiency zone broad advantages. Compact, light weight, easy installation, small footprint. Installation and Use: horizontal, vertical and ceiling can be installed. Ventilation, air and pipeline pressure can be used. Fan use, maintenance, maintenance 1, maintenance. A, should be carefully checked before installation whether the blades and chassis have damaged or deformed due to the transport, Shou pressure delivery outlet, or should be installed until after the repair; B, there is no reason to check the blade and duct connection screws loose touch shell, such as uneven blade duct clearance before installation should be adjusted; before C, fan start, pressure delivery outlet height from the ground, we should first check whether the internal fan and piping interfere with the rotation of the article; D, check the motor insulation performance is good, after turning on the power to check friction collision and abnormal vibration; E, in normal operation, in case the following conditions should immediately stop inspection: 1, the motor temperature exceeds 70 degrees Celsius; 2, motor Chang white smoke; 3, where a strong vibration or magnetic blocks have a greater voice. Pressure delivery outlet National Standard | Huainan pressure delivery outlet | Tianchang pressure delivery outlet provided by the Shandong Air Conditioning Equipment Co. GREAT fan.
