Here we do further elaborated on some of the advantages of some of the problems of traditional energy-saving air compressor and air compressor Cottle: a serious power loss. The traditional loading and unloading compressor energy consumption in use: 1, energy-consuming loading after the pressure has reached the desired working pressure, the traditional control methods adopted at its pressure will continue to rise until the unloading pressure. Pressurized process, will occur more heat and noise, and then causing power loss. On the other hand, high-pressure gas before entering the pneumatic components, the pressure demand pressure through the valve, the same energy in the process. 2, unloading energy consumption when the pressure reaches unloaded, active open air compressor unloading valve, air compressor motor idling price, forming a large energy consumption. Power compressor unloading of about 30% to 50% at full load, showing the traditional air compressor has a significant saving space. Second, Cottle energy-efficient permanent magnet synchronous inverter compressor and an ordinary power frequency compressor contrast, we know that the air compressor through "specific power" (input power / displacement per minute) to determine whether the energy-saving , that is, the lower the displacement under the same input power is better than power. Traditional air compressor because the input power is relatively high and therefore use will consume more power, resulting in a lot of waste; and Cottle permanent magnet synchronous inverter compressor is significantly reduced through improved input power than the power Xianyang air compressor, for business users to save considerable electricity compressor, so as to further reduce manufacturing costs users. 2, compared to the magnetic field Cottle energy-efficient permanent magnet motor and induction motor is the basis for the motor to achieve electromechanical energy conversion, according to the motor way to establish a magnetic field can be divided into electrical excitation and permanent magnet motors. Compared with the electrical excitation motors, permanent magnet motors Cottle has the following advantages: 1) High efficiency: the abolition of the excitation system losses and improve the efficiency of 5-12%. High power factor, the big moment inertia ratio, the stator current and stator resistance loss is reduced, and the rotor parameters can be measured, controlled performance is good. Direct drive motor, no speed slip, no bearings and connecting transmission efficiency improved by more than 3%. . At present, energy-efficient permanent magnet motors have reached mainstream adoption of a national energy efficiency standards. 2) Low noise: rational design field, flux density distribution, broader and lower operating noise operating frequency range. 3 Cottle, maintenance costs 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 participate actively with other research units to work together to strengthen the depths with "research use", so in order to provide guidance for Scientific Research and the actual production, in order to verify the actual production for the university to provide research, promotion 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, to master the core technology the formation of marine power reciprocating compressor manufacturing capacity.
