Rotary fan workflow is: 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, Harbin rotary fan, clever structure, performance excellence. Blowers all high-quality materials, compact structure, durable, high performance, long-term use of a small fault. 4, maintenance simple. Low speed, wear, long life. Rotary blower cast iron cast from the host, the metal ring 2 (or spring 8), host a shaft, a rotor, vane 4, an eccentric cylinder, pump cover 2 composition, where the fan rotation well, where fans metal ring, rotor vane pump cover and eccentric cylinder made of wear-resistant castings, rotary fan factory outlets, the host axis of 45 # steel manufacturing. rotary vane blower 4 is embedded in the aliquot inner rotor, rotary fan shaft fastened to the center of the rotor, with bearings at both ends of the shaft and connected to the front and rear pump cover mounted on an eccentric cylinder, then embedded in the rotor and the rotor vane and the inner wall of the cylinder 4 formed four volumes ranging from space, the rotary fan is running, pushing the metal ring or spring slide along the cylinder wall uniform motion, rotary blower block from the suction port, the suction port guide gas tank, exhaust port , vent gas guide groove formed a working process by Rotary fan: suction stroke, compression stroke, discharge stroke three-part rotation when rotary blower, rotary blower Which is good, so that four slide rotor slot. piece reciprocate, the air sucked into the compression discharge constitutes fan. Rotary fan Which is good, Harbin rotary fan, Zhucheng East Machinery Co., Ltd. by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd.
