Three energy-saving transformation methods for air compressors

With the continuous development and progress of society, energy conservation has become an increasingly topic of concern to people. All walks of life are taking active and effective energy-saving measures. Below, we will share with you the energy-saving transformation methods of air compressors.

　　 Solve air compressor leakage and gas usage

According to testing by authoritative organizations, only 10% of the electric energy consumed by the air compressor is converted into compressed air, and the remaining 90% is converted into heat energy. It can be seen that compressed air is ten times more expensive than electricity, but we often ignore it. at this point. In most factories, the sound of air leakage can be heard everywhere, but no one pays any attention. If we solve the leakage problem, a lot of energy will be saved. Therefore, when we hear air leakage, we must take appropriate measures in time. Measures.

There are also some factories that have big misunderstandings in the way of gas use. For example, in circuit board manufacturers, most electroplating lines use vibration to increase the plating capacity of small holes. Some manufacturers prefer to use gas vibration to achieve this purpose. As everyone knows, it consumes more than ten times more electricity than using electric vibration.

　　 Therefore, the energy saving of air compressors should avoid improper use of air while preventing air leakage in time.

　　 Air compressor energy saving transformation

　　 There are two main ways to transform air compressor energy saving:

　　1. Frequency conversion speed regulation method

　　Adopt frequency conversion speed regulation method to reduce the shaft power output of the air compressor motor. Before the transformation, when the pressure of the air compressor reaches the set pressure, it will automatically unload; after the transformation, the air compressor does not unload, but reduces the air output of the compressor by reducing the speed to maintain the required air network. The lowest pressure. There are two places to save energy:

　　(1) Reduce the power consumption caused by the sudden change of the compressor from the unloaded state to the loaded state.

　　(2) The motor's operating frequency is reduced below the power frequency, which reduces the output power of the motor shaft.

The above two methods have reduced the energy consumption of the air compressor during operation to varying degrees, but the air compressor generates such a large amount of heat during the work process to let it radiate into the air for a long time. It cannot be said that it is not a great regret that it has not received general attention from users within a period of time.

　　 2. Centralized control method

　　 Adopt centralized control method for multiple air compressors. The number of air compressors running is automatically controlled according to the gas consumption. Before the transformation, the number of air compressors turned on is fixed.

　　(1) If the air consumption is further reduced, the air compressor with good performance will automatically stop. In the case of (1), the air compressor consumes electric energy even when it is unloaded. After the transformation, the corresponding number of air compressors can be stopped, and the number of operating units is reduced, which undoubtedly saves electricity.

　　(2) When the air consumption is reduced to a certain amount, the air compressor reduces the air production by reducing the loading time.

　　 Waste heat recovery

　　 Air compressor waste heat recovery is a very environmentally friendly energy-saving method, and it is also a highly respected energy-saving method. Air compressor waste heat recovery is to transfer the high temperature oil of the air compressor to cold water through heat exchange and other technical treatments. The cold water is heated and flows into the heat preservation water bucket, so that the purpose of heat energy recovery can be achieved.

Because 73% of the heat energy of the air compressor is in the oil, and the technical treatment of the oil heat exchange, the result will be a continuous flow of hot water, that is, the air compressor can work at a constant temperature. It can also meet the hot water needed by the factory or life, killing two birds with one stone, and the hot water produced by the air compressor waste heat recovery technology does not require any additional costs, which in turn reduces the factory's investment in producing hot water.
