Description

technical field [0001] The invention relates to an air compressor, in particular to an air compressor energy efficiency test method and a test system based on the big data of the Internet of Things. Background technique [0002] Air compressor (English: air compressor, referred to as air compressor) is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generating device for compressing air. . As one of the main industrial products, the air compressor is an indispensable equipment in every factory. [0003] There are many types of air compressors, which can be divided into positive displacement compressors, reciprocating compressors, and centrifugal compressors according to their working principles. Among them, the working principle of the positive displacement compressor is to compress the volume of the gas, so that the density of the gas molecu...

Problems solved by technology

[0004] Screw air compressors have become the mainstream of the market. At present, the industry is constantly eliminating air compressors with poor energy efficiency. In order to improve the energy efficiency level of air compressors, improve the energy-saving efficiency of air compressors, and monitor the energy efficiency of air The air compressor test needs to manually go through huge test equipment, complicated test process, and complicated test calculations to complete the energy efficiency test of an air compressor. Due to too many restrictive conditions, it is impossible to achieve fast and accurate testing. The market demand for compressors continues to increase, and the original test methods cannot meet the test requirements of air compressors, and various performances of air compressors are related to different working conditions, so it is necessary to test the different working conditions of air compressors to obtain a comprehensive Energy efficiency level, in order to quickly and automatically measure the energy efficiency level of the air compressor under different working conditions, therefore, this test and test system was invented to realize the automatic, fast and accurate detection of the energy efficiency level of the air compressor

[0005] The traditional variable frequency air compressor energy efficiency test needs to manually adjust the air compressor outlet pressure, and wait for the pipeline pressure to stabilize before measuring the data. Depending on the experience of the personnel, the opening of the valve, and the size of the model, it often takes at least half an hour. It is necessary to adjust and stabilize the test pressure, and the test pressure is prone to data fluctuations due to environmental influences, which requires constant adjustment by testers, which takes a long time and complicated operations
