Application of pressure sensor in air compressor safety management system

In the safety management system, the pressure sensor realizes the side airbag control. Air compressor safety management system is also a field where sensors are widely used. There are two solutions for controlling the side airbag of the air compressor: acceleration sensor and pressure sensor. Authoritative data shows that, compared with the acceleration sensor, the pressure sensor is nearly 3 times faster than the acceleration sensor in detecting the speed of side impact, and the probability of misoperation is smaller. It is worth mentioning that the miniaturized sensor uses micro-machining technology to integrate micron-level sensitive components, signal conditioners, and data processing devices on a chip. Because of its small size, low price, easy integration, etc., it can improve the accuracy of system testing. For example, the micro pressure sensor and the micro temperature sensor are integrated together, and the pressure and temperature can be measured at the same time. Temperature influence. At present, many miniature sensors are available, such as pressure sensors.

The intelligent sensor is equipped with a dedicated computer, and its rapid development has improved the safety performance of the air compressor to an unprecedented height. With the development of microelectronics technology and micro-machining technology, sensors are developing in the direction of miniaturization, multi-function, and intelligence. Industry experts are therefore optimistic about the development prospects of air compressor sensors in China. They believe that the increase in the number of air compressors and the increase in sensors used on each air compressor determines that the capacity of the Chinese sensor market will continue to increase, and the Chinese sensor market is entering a period of vigorous development.

Air compressors are essential equipment in various factories, road construction, mining and construction industries. They are mainly used to provide a steady stream of compressed air with a certain pressure, such as supplying air to pneumatic valves and to the process flow that requires certain pressure gas. Gas source. There are many types of air compressors, such as screw air compressors, piston air compressors, centrifugal air compressors, scroll air compressors, etc., and the market potential of screw air compressors The industry is widely used. The air compressor uses a loading-unloading valve in its control to control the air supply of the air compressor. Due to the working cycle of the air equipment or the difference in the production process, the air consumption fluctuates, and sometimes the air compressor is frequently loaded, Uninstall. After the air compressor is unloaded, it still runs at power frequency, which not only wastes electrical energy but also increases the mechanical wear of the equipment, and the loading is a sudden process, which will have a greater impact on the equipment and the power grid. Therefore, the frequency conversion transformation of the air compressor has the effects of improving the start and operation of the motor, reducing the mechanical wear of the equipment, and saving electric energy within a certain range.
