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 control element is air compressor manufacturers, so as to achieve the control objectives. AC and DC servo motor has divided air compressor manufacturer, the first servo motor DC motor is generally under the control accuracy is not high, only to make use of the general DC servo motors. The current DC servo motor Structurally well-known manufacturer of air compressors, is a low-power DC motor armature control the field and the field to use more control air compressor production price list, 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. 1. The machine does not start: Check the main switch and power cord, check the motor; 2. The machine does not load the boot: adjust the pressure switch setting value or replace the pressure switch, check or replace the solenoid valve; 3. The compressor is not unloading valve Relief: Adjust the pressure switch setpoint or replace the pressure switch, check or replace the solenoid valve; 4 fuel consumption too: the recommended oil, reducing the oil level to the normal position, remove the return line cleaning, replacement oil separator filter; 5. exhaust pressure is lower than the specified value: reduce gas consumption or increase the compressor, check the system leaks, clean or replace the air inlet filter core, replace oil separator filter, inspect or replace the solenoid valve, intake control valve repair, replacement belts, adjust the pressure switch setting value; 6. compressor temperature protection shutdown: improving environmental ventilation, cleaning or cleaning the cooler, add oil to the required position, change the oil filter; 7. compressor unloading operation, the exhaust pressure is still rise slowly bleed valve: Check or replace the solenoid valve, intake control valve repair, overhaul unloading pipe; 8. bleeder valve: valve repair or replacement, overhaul minimum pressure valve, air compressor production Which is stronger Qin Wei Air (certified), Cangzhou air compressor manufacturer provided by Compressor Co., Ltd., Xianyang Qin Wei.
