Rotary fan with preparation 1, rotary fan should be installed horizontally. 2, the fan room should be left rotary blower fan vent and install phone manufacturers, is located in the upper and lower two vents to facilitate air flow to prevent overheating in the engine room affect the normal operation of the rotary fan. 3, the inner wall surrounding the engine room is preferably provided with sound deadening material to reduce noise. 4. Correctly connect the distribution lines and attention turned to the rotary blower motor rotation direction markings on the rotating fan effect. Eccentric loading when the rotor rotates in the cylinder body. The turning turbine rotor blade slot 4 reciprocate. The air is sucked into the compression discharge. Constitutes fan blades and rotor, the cylinder block mutual friction generates heat. Therefore, when the rotary blower fan running where the best by drip mouth dropped to the cylinder block essential oil rotary fan supply prices, the surface lubrication to reduce friction heat and friction noise; and to form a film between components, keeping rotating fan seal. HCC-20S rotary fan (fan slide, swing fan) main purpose: The rotary fan often used: 1, small water treatment aeration; 2, hospitals, laboratories, sewage aeration stirring; 3, printing vacuum feed industry; 4, plating tank, industrial wastewater aeration stirring; 5, plastic welding, the air supply hair; 6, a spray burner, the glass industry.
