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 air compressor manufacturers, 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 compressor manufacturers to improve the efficiency of 5-12%. High power factor, torque inertia ratio large well-known manufacturer of air compressors, the stator current and stator resistance loss is reduced screw air compressor manufacturer, 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, reduce maintenance costs, also known as worm compressor single screw compressor, meshing pair consists of a single screw compressor 6 screws and two 11 tooth star wheel composition. Worm while meshing with the two-wheel balancing force even if the worm, and also allows the displacement doubling the volume of the air compressor is small, weighs only 9 cubic meters (9m3 / min) per minute worm only piston compressor 1/6. The balance of power so that the worm worm compressor has a number of advantages: high performance and high efficiency air compressor equipment - screw air compressors with high capacity compression assembly cylindrical rotor speed is low and optimum fuel injection, to achieve high efficiency and high reliability. Until 2012, the manufacturers design ensures the system temperature and air temperature is very low. To ensure that all parts are the best cooling effect and maximum service life. Drive concept compressor equipment - screw air compressor through the efficient use of the transmission system to suit the optimum speed drive compressor components. During normal operation without any maintenance. With a maintenance-free, highly reliable and high efficiency advantages.
