    The air compressor is used to increase the pressure for gas, transportation and improve the gas pressure, so as to meet the production process or power equipment needs a special machine. In such as ceramic, glass, toys, clothing, machinery manufacturing, plastics and other industries enterprises in manufacturing industry, most require the use of 10 meters above the 3/ air compressor, and even the need to run multiple, in order to meet the production. Practice has proved, select and fulfill the compressor will be reached for users to save electricity, reduce cost, increase benefit. By the testing data of air compressor system and the pipe network, to improve the compressor power utilization way, mainly in the following few:
1, the correct selection of compressor to create a new or old compressor compressor system update, must pay attention to the choice of the appropriate type of the compressor, the compressor should choose advanced energy-saving, and the performance indicators to meet the use requirements. Following the principle of selection: (1) operating performance, a clear understanding of the use of the main parameters of compressor products and requirements, to see whether it can meet the requirements of service conditions. (2) to ensure that the requirements of the production process under the condition of safe and reliable operation, the selection to the often running conditions selection basis, and should not be with the greatest condition is the basis for selection. (3) compressor supporting ancillary equipment, such as buffer, gas cooler, oil separator, etc., should be matched with the host machine, and meet the requirement of. (4) to consider the energy saving, investment recovery period: payback period =p1-p0/p220 V Q mm. The general air does not exceed 8-10 M / s.. In addition, to reduce the gas leakage loss. The compressor at all levels inside and outside the formation of pressure difference, may leak through the valve, piston ring, packing is not tight, resulting in loss of exhaust, resulting in increased power consumption.
3, strengthen gas management, rational use of compressed air to the air compressor station to implement gas production and gas management, the installation of gas meter gas post, timely statistics of gas, gas consumption, and formulate the evaluation index. The rational use of compressed air supply, reduce energy consumption, can be considered from the following four aspects: (1) the whole pressure. At present, many factories exist in the turbine exhaust pressure and the production process does not adapt to the problem, often exhaust pressure is higher than the actual pressure required should be adjusted. The test showed that the compressor full load, the exhaust pressure 0.1MPa lower motor input power can be reduced by 5-8%. (2) the continuous gas supply to intermittent supply. Some enterprises supply and gas compressor is not consistent, continuous operation and the process of intermittent gas compressor is often idle or emptying, the waste of power. In this case the compressor according to the need to open the gas stop timing, or set up large gas tank. (3) arrange reasonable operation of the compressor. In the work of a number of compressors under the condition, should produce compressor station economic operation chart, so that the power consumption of the minimum. By testing the statistical characteristics of the compressor power consumption or run alone or parallel operation, should provide the most economical combination of the compressor to work for the longest time, while the lowest efficiency just as the load regulation for compressor. According to the gas pressure, the exhaust pressure of different combination, make the best use of it to improve the operation efficiency of the equipment. (4) increase the load rate of the compressor. Because the compressor rated exhaust volume selected with gas do not match, resulting in low load rate of the motor speed control device, can be used to adjust.
