螺杆式空压机的原理是一对平行面齿合的內外电机转子在汽缸旋转，使电机转子唇间的气体持续造成规律性的容积转变。气体沿电机转子中心线从吸进侧面輸出侧运输，完成螺杆式式空压机的呼吸、缩小和排气管的整个过程。
The principle of a screw air compressor is that a pair of parallel toothed inner and outer motor rotors rotate in the cylinder, causing the gas between the rotor lips of the motor to continuously cause a regular volume change. The gas is transported along the centerline of the motor rotor from the suction side to the output side, completing the entire process of breathing, shrinking, and exhaust pipe of the screw type air compressor.
因为空气压缩机在超负荷下长期性运行的概率，客户只有依据型号选择时的大要求明确电机容积，造成 空气压缩机系统软件的裕量大。传统式的空压机选用星三角降血压启动，但在直流启动时仍能做到额定电压的2-3倍，危害电网的平稳。大部分空压机全是持续运行的，由于一般空压机电机自身不可以依据工作压力要求的转变完成降速，使电机的功率与当场具体工作压力要求相符合，造成 空供气量钟头满载运行，造成输出功率消耗。据调查，空气压缩机占大中型机械设备（离心风机、泵、加热炉等）耗电量的近15%。空压机的节能项目具备关键实际意义。
Due to the probability of long-term operation of the air compressor under overload, customers only have to specify the motor volume based on the large requirements when selecting the model, resulting in a large margin of software for the air compressor system. The traditional air compressor uses a star delta to lower blood pressure for start-up, but it can still achieve 2-3 times the rated voltage during DC start-up, which poses a threat to the stability of the power grid. Most air compressors operate continuously, and due to the fact that the motor of the general air compressor cannot complete the speed reduction according to the change in working pressure requirements, the power of the motor matches the specific working pressure requirements on the spot, resulting in the air supply hour running at full load, resulting in output power consumption. According to the survey, air compressors account for nearly 15% of the electricity consumption of large and medium-sized mechanical equipment (such as centrifugal fans, pumps, heating furnaces, etc.). The energy-saving project of air compressors has key practical significance.
螺杆式式空气压缩机的运行关键由产品成本、维护保养成本费和电力能源成本费组成。电力能源成本费约占总经营成本的2/3。根据30%的电力能源成本费和直流变频起动后对机器设备的危害，也将降低检修量，进而大大的运行成本费。直流变频自动控制系统具备的工作压力控制力。根据将空压机的气压輸出与客户用风系统软件所需排风量相符合，能够 使管道网系统软件工作压力维持稳定，合理地提升气路品质。软启动器具备软起动作用，可降低启动对制冷压缩机及机械零部件的冲击性，提升可靠性指标，增加制冷压缩机使用期。另外，降低空压机起动对电网的危害。
The key to the operation of screw air compressors is composed of product costs, maintenance costs, and electricity and energy costs. The cost of electricity and energy accounts for approximately two-thirds of the total operating costs. According to the 30% electricity energy cost and the harm to machine equipment caused by DC variable frequency starting, the maintenance volume will also be reduced, resulting in a significant increase in operating costs. The DC variable frequency automatic control system has the ability to control the working pressure. By matching the air pressure output of the air compressor with the required exhaust air volume of the customer's air system software, the working pressure of the pipeline network system software can be maintained stable, and the quality of the air circuit can be reasonably improved. The soft starter has a soft starting function, which can reduce the impact of starting on the refrigeration compressor and mechanical components, improve reliability indicators, and increase the service life of the refrigeration compressor. In addition, reduce the harm of starting the air compressor to the power grid.
伴随着螺杆式式空气压缩机在工业生产、矿产业、诊疗业乃农牧业中的运用愈来愈多，尤其是在工业生产行业，空气压缩机的用电量居首，绝大部分的空气压缩机全是由电机驱动器，历经过滤装置过虑后，它进到制冷压缩机空气压缩，空气压缩被油气分离器輸出。要是空气压缩机处在运行状态，电机以额定值转速比运行，空气压缩机的輸出气体总流量根泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线据旁通阀的开启度开展调整。
With the increasing use of screw type air compressors in industrial production, mining, diagnosis and treatment industries, as well as agriculture and animal husbandry, especially in the industrial production industry, the power consumption of air compressors is the highest. The vast majority of air compressors are driven by motors. After filtration and filtration, they enter the refrigeration compressor for air compression, which is output by the oil gas separator. If the air compressor is in operation and the motor is running at the rated speed ratio, the total output gas flow rate of the air compressor is adjusted based on the opening degree of the bypass valve.
