Rotary fan with preparation 1, rotary fan should be installed horizontally. 2, the fan room should be left vent and install ventilation fans, vents to be set in the vertical air convection rotary blower two easy phone manufacturers, in order to prevent the room temperature is too high impact rotary fan running. 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. So the fan operation, the drip mouth dropped to the cylinder block necessary lubricants, lubricating surface to reduce friction heat and friction noise; and part is formed between the layer of film fans to keep rotating seal. Rotary fan inlet air damper adjustment rotary fan inlet damper on the fan to start with pressure generated when the belt pressure to prevent impact, be sure to open before starting the manual or electric vent valve; To prevent burn off oil and gear and bearing swivel fan prices, then slowly move when checking whether the flexible rotary fan coil fan supply price, you need to move the disc by hand, if the disk is moving flexible press the start button, the fan needs to reach full capacity; should regularly check whether the oil tank to the oil level line already close the vent valve, avoid overloading run run. Close to stop using rotary fans, in order to extend the life of the fan, open the vent valve first, then press the disconnect button rotary fan phone manufacturers _ _ Zhucheng East Han Machinery Co., Ltd.
