There is no belt drive, which saves power loss and maintenance costs. The single-cylinder compression realizes the two-stage compression function of the ordinary belt conveyor, and has high energy efficiency. It is the first choice for large flow and high pressure in the environment without electricity. The utility model designs an air selection mechanism in conjunction with the air cylinder of the power air compressor, and adopts a valve plate valve structure matched with the air cylinder, which can automatically inhale and exhaust air through the angle of crankshaft rotation, regardless of whether it is forward rotation or reverse rotation. can achieve compression.
