Injected screw compressor air compressor to become the new mainstream of development, with superior performance and reliable air compressor parts, it runs small vibration, low noise, high efficiency, no wearing parts. Between yin and yang between the rotor and the rotor and the precise fit between the body shell gas recirculation reduces leakage and improve efficiency; intermeshing rotors only, no cylinder reciprocating motion, reducing the vibration source and noise source; bring a unique lubrication many advantages: (1) by virtue of the pressure difference generated itself continuously injected into the compression chamber and bearing lubricants, simplify complex mechanical structure. Role (2) can be injected into the oil in the oil film between the rotor, the device has a lubricating and cooling, deputy rotor can be directly driven by the main rotor, without the help of high-precision timing gears. (3) is injected into the lubricating oil may increase the effect of air-tight. To improve the volumetric efficiency of the air compressor air compressor Cottle, from the energy point of view, there are energy efficient oil-free compressor will definitely higher than the oil-free air compressor. (4) oil can reduce the noise generated due to high frequency compression. (5) air compressor during use, the oil mist and thoroughly mixed with the high temperature compressed gas, the lubricating oil at high cycle speed, repeatedly heated and cooled while the air moisture and corrosive gases more accelerated oxidative deterioration of oil. Thus multiple use of synthetic lubricants, which not only can absorb a large amount of heat of compression, and the exhaust gas temperature is not too high, not because of different thermal expansion coefficients of friction generated between the rotor and the casing. (6) of compressed air and gas will cause many problems of use, precision filter even after treatment can not be completely oil-free state, although there are higher energy efficiency compressor oil Xianyang compressor, but , precision will generate additional purchase, replacement costs, and some of the pressure loss. 1: servo motor servo motor widely used in various control systems, the input voltage signal can be converted to mechanical output of the motor shaft, the drag element is controlled, so as to achieve the control objectives. DC and AC servo motor points, the first servo motor is a general DC motor, under the control accuracy is not high, only the use of a general DC motor as the servo motor. Current DC servo motor Structurally compressor is a low-power DC motor armature control and use more excitation field control, but usually armature control. 2: stepper motor stepper motors are used in the manufacture of CNC machine tools, due to the stepper motor does not need A / D converter, a digital pulse signal can be directly converted into angular displacement, it has been considered the best CNC machine actuators . In addition to the CNC machine tool applications, stepper motors can also be used in other machines, such as an automatic feeder in the motor, as a general floppy drive motor can also be used in the printer and plotter. 3: torque motor torque motor with a low speed and high torque characteristics. Generally in the textile industry often use the AC motor torque, and it works the same structure and single-phase induction motor. 4: switched reluctance motor switched reluctance motor is a new variable speed motor, the structure is extremely simple and robust, low cost, high speed performance, the traditional control motor strong contender, with strong market potential.
