On the localization process of the compressor case with the rapid development of air compressor industry, air compressor air compressor market concentration gradually increased, gradually formed a group of leading companies in the future with technology, energy-saving advantages of leading enterprises will continue to increase, these enterprises to continuously improve the competitiveness of industry consolidation. However, China's compressor industry has already made a breakthrough, but it still has to import key components, has become a stumbling block localization. Small scale, scattered distribution, low industrial concentration; the lack of high-end technology, the large proportion of low capacity; product homogeneity. Faced with these issues and the fierce market competition, enterprises should increase the strength of the air compressor, the implementation of structural adjustment and industrial upgrading; while enterprises should vigorously accelerate technology development, ongoing product innovation, enhance their market competitiveness. Related enterprises should speed up elimination of outdated industrial, high energy-consuming equipment, promote compressor equipment upgrade from low value to high value-added, leading to the further development opportunity for the compressor industry. Compressor Co., Ltd. Xianyang Qin Wei analysis: In recent years, Xianyang Qin Wei Compressor Co., Ltd., whether in technology, equipment, or in terms of personnel, have increased the intensity of Xianyang compressor innovation, further narrowing the gap with foreign countries. But at the same time, companies should continue to focus on innovative research and development, improve the product line, to lay the foundation for the realization of further localization of the compressor. Compressor Co., Ltd. Xianyang Qin Wei screw compressors with high reliability, easy operation and maintenance, the power balance is good, strong adaptability advantages Qin Wei air compressors, mining drilling equipment become the preferred source rock and slag wind, involving manufacturing difficulty (screw compressor rotor tooth surface is a curved space, the need to use a special tool for processing on expensive special equipment, its high pressure casting cylinder machining accuracy also have higher requirements) and market quantity (by rotor stiffness and bearing life and other constraints, determine the cause can not be made miniature), the localization rate is not high, the majority of domestic drilling equipment also matching the price is more expensive imported screw compressors. According to the conditions analysis and practical experience of the screw compressor, enables early detection of hidden faults and timely maintenance and avoid failures scrapped, a single device can save parts costs several hundred thousand dollars. Screw compressor works: 1. Intake Process: When the rotor rotates, the yin and yang of the rotor tooth groove space go to the inlet end of the wall opening, its largest space Cottle air compressor, then the rotor tooth groove space inlet connected, because tooth groove gas is completely discharged when the exhaust, the exhaust is completed, tooth groove in a vacuum, when the go to the air intake, i.e. outside air sucked into the yin and yang of the rotor axial The teeth of the trench. When the gas filled the tooth groove, the intake-side end face of the rotor to turn from the housing inlet, i.e. the gas enclosed in the tooth groove. 2. Compression Process: yin and yang of the rotor at the end of inspiration, the yin and yang of the rotor prongs will be closed with the cabinet, then the gas is no longer in the tooth trench drain. Its engaging surface gradually moves towards the discharge end. Tooth groove engaging surface and the space between the exhaust port gradually decreases, the gas is compressed teeth trench pressure increase. 3. Exhaust process: When the engagement end surface of the rotor and the casing to the air outlet, the compressed gas begins to discharge, until the engagement surface of the tooth tip and the tooth groove moved to the end face of the exhaust gas, then the male and female rotors engaging surface and cabinet exhaust port tooth groove space is 0, i.e., the exhaust process is completed, at the same time the length of the engagement surface of the tooth groove of the housing of the rotor between the air inlet and the longest, the intake process is carried out again . Cottle air compressor, air compressor, air compressor Qin Wei, first-class technology provided by Compressor Co., Ltd., Xianyang Qin Wei. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) strong, credible, Xianyang in Shaanxi compression, separation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Qin Wei Air and you hand into the brilliant, for a better future!
