Correct selection of air compressor improves the utilization rate of air compressor electricity. Air compressor is a special machine used to increase the pressure of gas to facilitate transportation and increase the pressure energy of gas, so as to meet the needs of production process or power equipment. When building a new compressor system or updating an old compressor, you must pay attention to choosing the right compressor model. You should choose an energy-saving advanced compressor, and its performance indicators must meet the use requirements. The principles of selection are as follows:
1. Understand the performance, scope of use, main parameters and required operating conditions of the compressor product to see if it can meet the requirements of the use conditions.
2. To ensure safe and reliable operation under the working conditions required by the production process, the selection should be based on the working conditions of regular operation, rather than the maximum working conditions.
3. The auxiliary equipment of the compressor, such as buffers, gas coolers, oil separators, etc., should be matched with the main machine and meet the use process requirements.
4. Consider the benefits of electricity saving, and the investment recovery period is:
Investment recovery period = p1-p0/p2 <?1/2-2/3 compressor life cycle
p1-the cost conversion value of purchasing energy-saving (new) compressor products;
p0-the cost conversion value of recycling old compressors after they are scrapped
p2-the annual electricity saving benefit conversion value
In manufacturing industries such as ceramics, glass, toys, clothing, machinery manufacturing, plastics and other industries, most companies need to use air compressors with a capacity of more than 10m3/min, and even need to operate multiple units in combination to meet production needs. Practice has proved that choosing and using compressors well will help users save electricity, reduce usage costs and increase benefits.
