Compressed air system
The compressed air system refers to the compressed air which is compressed at atmospheric pressure and is transported to the pneumatic system at a higher pressure. It is composed of following equipment.
(1) Compressors. The air at atmospheric pressure is compressed and transmitted to the pneumatic system at a higher pressure. This transforms mechanical energy is into air pressure.
(2) The motor provides mechanical energy to the compressor, which transforms electrical energy into mechanical energy.
(3) Pressure switch which controls the pressure in the gas tank to control the motor is regulated to a maximum pressure. When this pressure is reached, the motor is stopped and another minimum pressure is regulated, and the pressure in the gas tank drops to this pressure and the motor is restarted.
(4) One-way valve. Let compressed air from the compressor into the gas tank. When the compressor closed, preventing the compressed air flow in the opposite direction.
(5) Sorage tanks can store compressed air. Its size is determined by the capacity of the compressor, the larger the volume of the gas tank.
(6) The pressure gauge shows the pressure in the gas tank.
(7) The automatic drainer does not require manual operation to drain all the water condensed in the gas storage tank.
(8) Safety valve. Compressed air can be discharged when the pressure inside the gas tank exceeds the allowable limit.
(9) Freeze-type air dryer. The compressed air cooled to a certain degree above zero, so that most of the moisture is in the air condensation. It eliminates the moisture in the rear system.
(10) Main pipe filter. In the main pipe, the main pipe filter must have the minimum pressure drop and oil mist separation capacity. It eliminates dust, water and oil in the pipeline.
