Recently, the Ministry of Industry and Information Technology "Marine power reciprocating compressor developed" project start will be held in Wuhan. Leaders from the Hubei Provincial Science Technology and Industry for National Defense and the Ministry of Sinopec Group Company, as well as representatives of petroleum machinery company, Sinopec Offshore Oil Engineering Co., Ltd., Huazhong University of Science and six participants participate in research units. This marks the official launch of the project. Development of marine power reciprocating compressors for air compressor company Xianyang Qin Wei is also a good news. It is reported that, "Marine power reciprocating compressor developed" project was on November 28, 2014 Ministry of Industry and Information Technology, Ministry of Finance documents approved, the project led by the Petroleum Machinery Company, the development cycle for January 2015 2017 12 months. Its contents include: marine power reciprocating compressor technology research and overall design; anti-corrosion material selection unit research and technology; Vice equilibrium at high speed movement and fatigue life analysis of key parts; high pressure cylinder and sealing technology research ; pulsating flow piping system analysis techniques; marine power reciprocating compressor noise damping technology research; compressed gas efficient cooling technology research; Marine Technology Research compressor intelligent control. As project lead unit, petroleum machinery company will actively participate in research units, together with other air compressors, strengthening depths with "research use", so as to provide guidance to the actual production of university research to the actual production of university research to provide validate and promote the close combination of theory and practice, and promote the effective implementation of the project implementation plan, and strive in key technology research marine power reciprocating compressor design, manufacturing, testing and other testing and installation, in accordance with the highest standards of strict national research project is completed, master the core technology of air compressor brand, the formation of marine power reciprocating compressor manufacturing capacity. Promote the development of science and technology of the times more machinery instead of labor, the rise and prosperity of the compressor industry has also led to a lot of the development of industry, oil-free screw air compressor models as one, in today's very epidemic. Whatever the model user must pay attention to the displacement of purchase options, often displacement parameters to be greater than the actual displacement, it is going to be influenced by other factors. Then factor oil-free screw compressor displacement, what does? Factors actual oil-free screw compressor displacement: 1, temperature. Ambient temperature affects the amount of intake air, in the same volume of air compressor parts, the higher the temperature, the lower air density, the less displacement; the lower the contrary Xianyang compressor temperature, the greater the displacement. 2 speed. Is proportional between oil-free screw compressor speed and displacement, and factors affecting the speed of the main grid voltage and frequency. 3, the leak. Between the compressor rotor and the rotor housing when the rotation is not in contact, there will be a gap in the middle, resulting in leakage. 4 loss. Compressed gas delivered to devices, there will be a period of piping, pipe bend over, pipe length, will want a certain amount of compressed air loss. 5, the cooling effect. Air compression process, the temperature will rise, expansion and contraction principle of the cooling effect is poor, reducing the displacement. Of course, the factors affecting the actual oil-free screw compressor displacement is far more than that, to remind the user when sorting machine, take this into account, to avoid displacement during the subsequent lack of use, and keep up with the production of situation. Air compressor repair, air compressor, air compressor Qin Wei, research the history of three decades of production 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!
