The motor directly drives the compressor, which makes the crankshaft rotate, and the connecting rod drives the piston to reciprocate, causing the volume change of the cylinder. Due to the change of the pressure in the cylinder, the air is allowed to enter the cylinder through the air filter (muffler) through the inlet valve. During the compression stroke, due to the reduction of the cylinder volume, the compressed air flows through the exhaust valve and enters the air reservoir through the exhaust pipe and one-way valve (check valve). When the exhaust pressure reaches the rated pressure of 0.7MPa, it is automatically stopped under the control of the pressure switch. When the pressure of the air tank drops to 0.5-0.6MPa, the pressure switch is automatically connected and started.
The air compressor is the core equipment of the pneumatic system and the main body of the electromechanical air source device. It is the device that converts the mechanical energy of the prime mover (usually the motor or the diesel engine) into the gas pressure energy, and it is the pressure generating device of compressed air.
There are many kinds of air compressors
1. According to the working principle, it can be divided into three categories: volume type, power type (speed type or turbine type) and thermal type compressors.
2. It can be divided into oil-free air compressor and oil lubricated air compressor according to lubrication mode.
3. According to performance, it can be divided into low noise, variable frequency, explosion-proof and other air compressors.
4. It can be divided into refrigerator compressor, air conditioning compressor, refrigeration compressor, oil field compressor, natural gas filling station compressor, rock drill, pneumatic tool, vehicle brake, door and window opening and closing, textile machinery, tire inflation, plastic machinery compressor, mining compressor, marine compressor, medical compressor, sandblasting and painting.
5. According to the type, it can be divided into fixed type, mobile type and closed type
Positive displacement compressor - a compressor that directly increases the gas pressure by changing the gas volume.
Piston air compressor
Piston air compressor
Piston compressor is a positive displacement compressor. Its compression element is a piston, which performs reciprocating motion in the cylinder.
Rotary compressor is a positive displacement compressor, and compression is realized by forced movement of rotating elements.
Sliding vane compressor is a rotary variable volume compressor. Its axial sliding vane slides radially on the rotor eccentric with the cylinder block. The air trapped between the slides is compressed and discharged.
