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 compressor, 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, compressor unloading valve active open, the motor idling, 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 greatly reduced by improving the specific power input power, for business users to save a considerable amount of electricity, 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 Qin Wei air compressor, air compressor price 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 1) arranged compressors and ancillary equipment shall meet the requirements of the manufacturer; (2) the compressor should be arranged in the vicinity of the device is pumped, the ancillary equipment should be close to the unit layout; (3 ) combustible gas compressor arrangement should meet the following requirements: 1 pitch) and fire equipment, non-explosion-proof electrical equipment should comply with national standards, "the explosion and fire hazard electrical installation design specifications" GB50028 and "fire protection design of petrochemical enterprises norms "GB50160 requirements; 2) should be open or semi-open layout arrangement. In cold or sandy areas can be arranged in the plant; 3) single drive power is equal to or greater than the CPI 150kw gas compressor plant, a building should not be shared with other A, B, C class room; above Xianyang compressor air compressor, shall arrange A, B, C liquid equipment, but personal use of high oil tank subject to this limit. (4) single compressor arrangement, when a high base, should be set according to the operating platform; when ancillary equipment more appropriate arrangement of two compressor prices, air compressor, air compressor Qin Wei, air compressor brand authority Limited by Wei Qin Xianyang compressor. 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!
