Reasonable use of air compressor

Gas production and gas management should be implemented for air compressor stations, and gas flow meters should be installed in the relevant gas-using posts, and the gas volume and gas consumption should be counted on time, and index assessment should be formulated. Reasonable use of compressed air to reduce gas supply energy consumption can be considered from the following four aspects:

(1) The whole gas pressure. At present, many factories have the problem that the exhaust pressure of the unit is not compatible with the production process. The exhaust pressure is often higher than the actual required pressure and should be adjusted. Tests show that: when the compressor is fully loaded, the discharge power of the compressor is reduced by 0.1MPa, and the input power of the motor can be reduced by 5-8%.

(2) Change continuous air supply to intermittent air supply. Some companies do not match the gas supply and gas supply time. The compressor runs continuously and the gas is used intermittently. The compressor is often idling or emptying, wasting electricity. In this case, the compressor can be shut down regularly according to the gas demand, or a larger air storage tank can be installed.

(3) Arrange the operation of the compressor reasonably. In the case of several compressors working in parallel, an economic operation chart of the compressor station should be produced in order to minimize the power consumption. Through testing or statistics, the power consumption characteristics of the compressors when running alone or in parallel should be specified. The most economical compressor combination should be operated for the longest time, and the compressor with the lowest efficiency is only used to adjust the load. According to different gas pressures, different combinations of exhaust pressures are used to maximize the efficiency of the equipment.

(4) Increase the load factor of the compressor. Due to the mismatch between the rated exhaust volume of the selected compressor and the gas consumption, resulting in a low motor load rate, you can consider using a speed control device for adjustment.
