Technological innovation in the air compressor industry in recent years
Air compressors are one of the key industries in the general machinery industry. China's air compressors started in the late 1950s and were developed after the founding of New China. It has undergone the initial digestion and absorption of the former Soviet Union products, the independent development in the 1960s and 1970s, and the large-scale introduction of international advanced technologies in the 1980s and 1990s.
In recent years, with the continuous decline of the domestic economic structural transformation economy and the oversupply of the domestic market, the air compressor industry has experienced a decline, both in terms of the number of orders and profit margins.
In order to cope with the huge challenges brought by market competition, domestic air compressor manufacturers have also accelerated the speed of product upgrades and increased technological innovation. The main technological innovations have the following:
1. Host high-efficiency technology: Analyze the operating efficiency of the air compressor through online measurement methods, replace the original low-efficiency host with an efficient host, and combine the local supercharging technology and high-efficiency grading technology to optimize the efficiency of the host.
2. Efficient grading and conveying technology: According to the pressure demand of users, the pressure level of the conveying pipe network is reasonably planned. Efficient grading of compressed air is achieved by laying pipe networks of different pressure levels. For every 1 kg of pipe network pressure, the system energy efficiency is increased by 3-8%.
3. Air compressor frequency optimization control technology: Through the frequency conversion speed regulation means to adjust the gas production of the air compressor, so that the gas production and gas consumption are highly matched, and the unloading rate of the air compressor is minimized.
4. Air compressor intelligent joint control technology: through the configuration of sophisticated sensing technology and platform data analysis technology, online collection of compressed air flow, temperature, dew point and other data, and through the algorithm optimization and joint control technology to achieve air compressor The group's energy-saving optimization runs.
5. Compressed air post-treatment energy-saving technology: the dryer is regenerated by the heat of the air compressor itself, and at the same time, the special design makes the regeneration process consume no compressed gas and realize the energy saving of the drying process.
6. Air compressor waste heat recovery technology: The high-efficiency heat exchanger is used to recover a large amount of heat energy generated during the operation of the air compressor, which is directly applied to the production or domestic heat of the enterprise and reduces the cost of the enterprise.
In the fierce competition of the air compressor market, many manufacturers felt the crisis and saw business opportunities. Only by continuously improving product performance, accelerating the pace of technological innovation, taking the advanced and differentiated routes, is the only way for air compressor manufacturers and many agents.
