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, 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, 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, a maintenance costs, energy-consuming loading Houketeer reach the desired working pressure in the pressure screw 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 Qin Wei compressors, 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 compressor 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. 3, the frequency of the main motor launch in spite of the impact of current large selection of decompression start, but still high starting current large air compressor cost, the impact on the grid, easy to form a grid instability and affect the operation of other electrical equipment safety. 4, the pressure instability, low degree of automation of traditional compressor bottom degree of automation, the output pressure of conditioning is to rely on the loading and unloading valves, control valve manipulation to complete, conditioning slow shake, low accuracy, the output pressure instability. 5, a large amount of air compressor equipment maintenance Frequency launch current, up to 5-8 times the rated current, the operation mode determines the loading and unloading valve must repeat the action, parts easy to aging, the frequency at high speed, bearing wear and maintenance of large equipment . 6, noisy-frequency high-speed operation continues beyond the rated working pressure of the pressure required, repeated loading, unloading, directly resulting in the power frequency operation.
