Rotary blower works against the inner cylinder rotating fan rotor rotates eccentrically biased, and the volume change of the blade rotor slots between the air intake, compression and discharge using differential pressure blower automatically lubricant to the operation drip nozzle inner cylinder was dropped to reduce friction and noise, while maintaining the cylinder of gas is not refluxed. four vane rotary fan embedded in the aliquot rotor, fastened to the rotor shaft center of the fan, fitted at both ends of the shaft front and rear bearing cover pump connection mounted on an eccentric cylinder, this time with four rotor embedded in the rotor vane and the cylinder formed four volumes ranging from space, Hangzhou rotary blower, rotary blower running, rotary blower where good, metal ring or spring push slide along the cylinder wall uniform motion, rotary blower airflow channel has the cylinder intake port, the intake port gas guide groove, vent, vent air guide trough. Overall, the rotary fan workflow is: intake stroke, compression stroke, discharge stroke three parts when the fan is rotated, so that the four vane rotor slot reciprocate, the air sucked into the compression discharge. it is also known as the fan rotary vane blower fan workflow: intake stroke, compression stroke, exhaust stroke of three parts. When the fan is rotated, so that the four vane rotor slot reciprocate, the air sucked into the compression discharge. Rotary fan characteristics 1, anti load changes, air flow and stability. 2, with the air chamber, smooth diffuser. All models with air chambers, to prevent air pulsation, smooth diffuser. 3, material well, rotating fans Which is good, clever structure, performance excellence. Blowers all high-quality materials, compact structure, rotary fan factory outlets, durable, high performance, long-term use of a small fault. 4, maintenance simple. Low speed, wear, long life. Rotary fan factory outlets, Hangzhou rotating fan, Zhucheng East Machinery Co., Ltd. by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd.
