Operating principle Rotary blower fan is biased against the inner cylinder rotor eccentric operation, and volume change blade rotor slots between the air intake, compression, spit. The blower pressure difference in operation automatically lubricated rotary fan to drip nozzle manufacturers, wholesale, inner cylinder was dropped to reduce friction and noise while maintaining the cylinder of gas is not reflux. Rotary fan their maintenance knowledge 1, must be hand use, personal service. 2, allowed sick to run. 3, periodically clear the dust inside, especially on the impeller dust, dirt and other impurities rotary fan Which is good, in order to prevent corrosion and imbalances. 4, repairs must be emphasized first stop off. 5, a thermometer and regularly check the sensitivity of the subject of oil. The main performance parameters of rotary blower with a flow, total pressure, power, speed and efficiency. (L) flow rate: the amount of fluid per unit time of the rotary conveyor is called flow fan. Common volumetric flow rate Q, said its unit is "resistant / s" or "m 3 / h". Strictly speaking rotary blower, rotary blower flow, especially rotary fan inlet volume flow. (2) Total pressure: energy per unit volume of gas in the rotary fan known as obtained full pressure or pressure to P expressed in units of Pa. (3) shaft power: prime mover power delivered to the rotary shaft on the fan, that is the input power, also known as shaft power, with p expressed in units of kw.
