In addition, the influence of the gas density on the performance of the compressor is not obvious, so that the universality of the machine is good. However, the piston compressor also has the obvious disadvantage that when the exhaust is discontinuous, the airflow pulsation is caused, and when the exhaust is serious, the airflow pulsation resonance is generated, so that the damage to a pipe network or parts can be caused. Lubricating oil is used in a common cylinder to lead gas to carry oil, and if the requirement on the quality of the gas is high, the task of purifying the compressed gas is heavy; when the lubricating oil is too little, the bearing is overheated to melt babbitt metal on the bearing bush, so that the bearing bush and the crank journal are engaged or the crankshaft is grooved to cause bending deformation of the crankshaft.

The reason for removing the oil in the low oil level and causing the overheating of the bearing is that a large area of friction is generated between the shaft and the bearing during the rotation because the surface of the rotating shaft is locally rough and the rotating shaft is not completely polished during the production. The traditional rotating shaft polishing is that the rotating shaft is directly polished by a manual work on the ground, but the rotating shaft is very heavy, so that the rotating shaft is very inconvenient to overturn and process, and finally the rotating shaft is not polished completely.
