The main performance parameters of rotary blower with a flow, total pressure, power, speed and efficiency. (1) Effective power: the total energy per unit time through a rotary fan gas obtained is called the effective power, in units of kw. (2) Efficiency: Rotary fan input power is delivered not all pass gas, which must be part of the energy loss, the gas is transported to obtain the actual power transfer than the original motive to the rotary shaft of the fan power to be small, they The ratio is called rotary fan efficiency. The higher efficiency of the rotary blower fan rotation where the cheapest gas is effectively part of the energy obtained from the rotating fan in the greater swing fan wholesale prices, the economy higher. Rotary fan with preparation 1, rotary fan should be installed horizontally. 2, the fan room should be left rotary fan vent and install ventilation fans, vents located in the upper and lower sections to facilitate air flow to prevent overheating inside the 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. So the fan operation, the drip mouth dropped to the cylinder block essential oil rotary blower use, the surface lubrication to reduce friction heat and friction noise; and to form a film between the parts to maintain the tightness of the rotary fan . Where is the cheapest rotary blower, rotary blower Nanning, Zhucheng East Machinery Co., Ltd. by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd. (www.dhlcfj.com) (www.dhlcfj.com) strong, credible, Shandong Weifang fan, ventilation equipment industry has accumulated a large number of loyal customers.
