Double stage compression screw machine: double stage compression screw machine gradually replaced the piston compressor

At present, domestic manufacturers of two-stage compression screw machine through the introduction of technology, technical cooperation or independent research and development, improve the technical content and performance quality of the product, with the improvement of the requirements of the use of environment, energy consumption, environmental protection and other aspects, refrigeration unit energy saving is one of its development trends.

According to reports, the two-stage compression screw machine is placed in the body of two screw with spiral groove meshing rotation and with the inner wall of the body and suction, exhaust end seat with the inner wall, resulting in volume changes between teeth, so as to complete the gas inhalation, compression and discharge process.

In recent years, with the continuous improvement of the tooth shape and other structures, the performance has been greatly improved. In addition, the screw air compressor has no clearance volume, high efficiency, no suction, exhaust valve device and other wearing parts. Therefore, at present, screw air compressor has become an advanced air compressor, especially oil injection screw compressor has been one of the main types of air compressor, has been widely used.

With the development of air compressor manufacturing industry, two-stage compression screw machine has replaced the trend of piston compressor. Screw air compressor has the characteristics of small size, light weight and easy maintenance. These characteristics will accelerate the rise of market share of two-stage compression screw machine.

Two-stage compression screw machine industry is a technology-intensive industry, the production process is relatively complex, processing accuracy requirements are high, product and technology update is difficult, the sustainable development of enterprises need not only certain RESEARCH and development strength and technical reserves, but also need a certain amount of practical experience accumulation.
