As the basic product of industrial modernization, screw air compressor is indispensable for modern industrial manufacturing. The energy consumption of air compressor is very huge, so it is necessary to save energy of air compressor. Energy saving and emission reduction have become the general trend, and sustainable development is also developing continuously. Energy saving is nothing more than reducing energy consumption as much as possible and producing products with the same quantity and quality as the original ones. The air compressor has been an electric tiger for so long, so it's time to do energy-saving transformation. Having said that, what aspects should the energy-saving transformation of the air compressor start with?
1.Variable frequency speed control
The application of variable frequency speed regulation in variable frequency air compressor can greatly improve the energy-saving performance of the air compressor. Adjust the rotation speed of the air compressor according to the output signal of the flow sensor, so that the air compressor can accurately output the required return flow, realize high-precision flow regulation, and ensure that the air compressor can operate safely and efficiently.
2.Suction pressure adjustment
Selecting the appropriate suction pressure can effectively reduce the efficiency of the compressor. In general, the lower the suction pressure, the greater the energy consumption, especially the suction pressure of the first stage of the compressor. Therefore, the suction pressure of the compressor can be appropriately increased, and the high-efficiency cyclone inlet separator can be added in the first stage suction, so as to further eliminate the resistance of the intake pipe network and obtain a higher suction pressure while ensuring sufficient treatment gas volume.
3.The pressure drop between air compressor sections decreases
The pressure drop between air compressor sections is also an important reason for compressor power consumption. In order to reduce the pressure, drop between sections, an efficient heat exchanger can be used to replace the inter-stage cooler, reduce unnecessary pipeline equipment and elbows, improve the operating conditions and reduce the scaling degree of the cooler.
4. Pipeline layout optimization
In order to further reduce the pressure drop in the pipeline, the pipeline layout needs to be adjusted to improve the rationality of the pipeline layout. The pressure loss can be used to evaluate whether the layout is reasonable (the pressure difference between the inlet pressure and the outlet pressure is not more than 5%). In the pipeline, the equipment that can cause pressure loss mainly includes dryer, cooler, control valve, elbow, etc.
5. Daily maintenance
The daily use and maintenance of the air compressor also have a great impact on the energy-saving effect of the air compressor. In daily use, the air compressor equipment shall be used in a standardized manner, preventive maintenance measures shall be taken to reduce the failure rate of the air compressor and maintain the working performance of the air compressor
In a word, energy saving of air compressor is necessary. Energy saving technology of air compressor is to reduce the energy consumption when it works.
