Energy is an important guarantee for China’s sustainable development and the foundation upon which humankind depends. With the gradual integration of the global economy, energy, and the environment, we are facing tremendous pressures from energy supply, energy environment, and energy security, as well as the challenges of continuously increasing and limiting the energy efficiency requirements of products. Energy-saving and environmental protection are the major development directions of compressors. .
With the increase in requirements for the use of the environment, energy consumption, and environmental protection, energy-saving refrigeration units are also one of their development trends. At present, the domestic series of screw refrigeration compressor COP value has been higher than the piston compressor, and has achieved 10% -100% range of stepless energy adjustment and internal volume ratio adjustable, which is also conducive to energy saving.
According to reports, screw-type refrigerating compressors use a pair of screws with a helical tooth slot placed in the body to rotate and engage with the inner wall of the machine body and the inner walls of the suction and exhaust end seats, resulting in changes in the volume between the teeth. In order to complete the gas suction, compression and discharge process.
In recent years, with the continuous improvement of tooth shape and other structures, performance has greatly improved. In addition, the screw compressor has no clearance volume, high efficiency, and no wearing parts such as suction and exhaust valve devices. Therefore, the screw-type refrigeration compressor has become an advanced refrigeration compressor. In particular, the oil-injected screw compressor has become one of the main types of refrigeration compressors and has been widely used.
With the development of refrigeration compressor manufacturing, screw refrigeration compressors have replaced piston compressors. Screw refrigeration compressors are characterized by their small size, light weight, and easy maintenance. These features will accelerate the market share of spiral refrigeration compressors.
The screw-type refrigeration compressor industry is a technology-intensive industry. The production process is relatively complicated, the processing accuracy is high, and the product and technology update are more difficult. The sustainable development of the company requires both a certain R&D strength and a technical reserve, and it also requires a certain practice. Accumulated experience.
At present, domestic screw compressor manufacturers improve their technical content and performance quality through technology introduction, technical cooperation or independent research and development. However, compared with international advanced level, their products are still in terms of profile, noise, and oil separation efficiency. There is a certain gap.
