The advantages of the piston air compressor are simple structure, long service life, and easy realization of large capacity and high voltage output. The disadvantage is that the vibration is large, the noise is large, and because the exhaust gas is intermittent, the output is pulsed, and a gas tank is required.
Piston air compressors come in a variety of configurations. According to the configuration of the cylinder, there are several types of vertical, horizontal, angle, symmetrical balance and opposite. According to the compression level, it can be divided into three types: single-stage, double-stage and multi-stage. According to the setting method, it can be divided into two types: mobile and fixed. According to the control mode, it can be divided into two types: unloading type and pressure switch type. The unloading control method means that when the pressure in the air tank reaches the set value, the air compressor does not stop running and opens the safety valve to perform the uncompressed operation. This idling state is called unloading operation. The pressure switch type control mode means that when the pressure in the gas tank reaches the set value, the air compressor automatically stops running.
1. Adjustment of pressure: When the pressure adjustment screw 1 is clockwise, the pressure is increased. Otherwise, the pressure is reduced, but the pressure difference is constant.
2, the adjustment of the pressure level: the pressure adjustment screw 2 clockwise, the action pressure rises, otherwise, the action pressure is reduced, but the pressure difference does not change.
3. When the air compressor is running to the set pressure, the saturation and deflation valve will discharge the gas inside the steel pipe. This is normal and not leaking.
4, 1-2 adjustment screws are related to each other.
5. Adjust the pressure and cut off the exhaust pressure of the compressor.
