Features and performance of general-purpose volumetric air compressors
Air compressors are widely used in various fields and are an important part of modern production and life. General-volume air compressors refer to compressors that change their intake volume in order to realize compression in the compression chamber; they are composed of an electric motor, a compressor unit, a valve, and an oil system, and the working process includes the suction process, compression process, and exhaust air process.
The main performance parameters of general volume air compressor refer to air delivery and exhaust pressure, energy efficiency, compressed air cleanliness, and other indicators.
Air delivery is an important indicator of the performance of a general-volume air compressor. Air delivery is the amount of air discharged from the compressor unit at a certain exhaust pressure, expressed in units of m3/min or m3/h. The compressor discharge delivery of general-volume air compressors can be designed according to the actual situation. The exhaust pressure of the air compressor is normally between 0.4 MPa and 1.0 MPa, and the exhaust pressure required for some special occasions may exceed 1 MPa.
The energy efficiency of general-volume air compressors is an important indicator to assess their quality. The ideal energy efficiency of an air compressor should be as low as possible while achieving the required delivery, so as to save electricity costs in production. Generally, the efficiency of a general volume air compressor ranges from 0.7-0.9.
The cleanliness of compressed air is another important indicator to assess the quality of air compressors. The cleanliness of compressed air refers to the maximum allowable amount of dust particles in the compressed air. The dust content of compressed air varies depending on the application, but it is generally between 0.01-0.1mg/m3.
In addition to the above main performance parameters, the noise and vibration of the general-volume air compressor must also meet the requirements. The noise level of a compressor usually ranges from 50 to 80 dB(A). In addition, the vibration level should not exceed 3.2 mm/s.
In summary, these are the main features and performance of general-volume air compressors. By understanding the performance of the compressor, it is possible to select an appropriate compressor according to actual needs.
