Subsequently, the compressed hot air is sent to the cooler 12 for cooling, and the cooled air enters the cyclone dust collector 15 for removing particulate matter, and finally outputs high-quality compressed air through the air outlet pipe.

[0065] Reference Figure 4 In addition, the system sets a return pipe 31 to return part of the purified air to the air intake part, and then passes through the second air filter 32 for secondary filtration before participating in the compression process again.

[0074] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 ,Detailed description of the working process,Introduction and preliminary filtration of air: At the beginning, the outside air enters the reciprocating air compressor through the air intake pipe 10. In this process, the first air filter 11 plays a key role, which filters out most of the dust and impurities in the air, ensures the quality of the introduced air, and thus provides a clean air foundation for the subsequent compression process.

[0075] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , air compression and power conversion: the power unit starts, the motor 40 drives the pulley 41 to rotate, and converts the rotational power of the motor 40 into the reciprocating motion of the piston unit 21. The piston unit 54 reciprocates in the cavity 17 in the body 16, compressing the air by reducing the volume of the cavity 17. This step is the core of the work of the reciprocating air compressor, which realizes the compression of the air and provides the power basis for the subsequent steps.

[0076] Reference Figure 4 , Air cooling and deep purification: The compressed air has a high temperature under high pressure. At this time, it is guided into the cooler 12 for cooling, which reduces the temperature and volume, making the air denser. Subsequently, the air passes through the cyclone dust collector 15, which uses the cyclone separation principle to remove finer particles, ensuring that the output compressed air is purer.

[0081] Convenient and safe operation:

[0082] Automatic filtering and cooling system: simplifies the operation process, and users do not need to perform complicated settings or adjustments.

[0083] Reference Figure 4 By setting the safety valve 30 and the check valve 32, the problems of system overpressure and air backflow are effectively prevented, ensuring the safety of equipment and operators.

[0084] Improved air quality;

[0085] Double filtration system: ensures that the air entering the reciprocating air compressor and the compressed air finally output are of high purity, meeting the high requirements for air quality in industrial and commercial use.

[0086] Extension of equipment life:

[0087] Reference Figure 4 , Optimized lubrication system: The configuration of the oil pump and the oil return pipe 31 ensures good lubrication of the internal components of the body 16, reduces wear and tear, and extends the service life of the equipment.

[0088] Through the above working process and the beneficial effects it brings, the reciprocating air compressor can not only efficiently provide high-quality compressed air, but also ensure the convenience and safety of operation, while reducing energy consumption and extending the life of the equipment.
