In recent years, China's rapid development of industrialization, industrial overall quality improved significantly, significantly enhance the international status. However, the process of industrialization over the pursuit of speed, making China the world's manufacturing superpower at the same time, paid no small price. Resources and energy and environmental issues have become a major bottleneck restricting China's sustained and healthy development of the industry. Xianyang Qin Wei Compressor Co. deeply understand the motor is the largest electricity end-use equipment. At present, China's motor to maintain about 1.7 billion kilowatts, with a total power consumption of about 3 trillion kwh, accounting for 64% of the motor power of social total electricity consumption, 75% of industrial electricity. At the same time, China's motor system (motor and drag devices) operating efficiency of 10 to 20 percentage points lower than abroad. It is estimated that the air compressor rental, motor energy efficiency for each one percentage point increase, the annual electricity savings of more than 260 one hundred million kwh; if the motor system efficiency gains of 5 to 8 percent, the annual electricity savings equivalent to 2 to 3 Gorges Power Station generating capacity. Because the motor in the field of low-carbon energy particularity, developed countries will increase the energy efficiency of the motor as an important energy-saving measures. From 1997 the United States began to impose efficient motor, 2011 also impose ultra-efficient motors; the European Union in 2011 began to impose efficient motors. Through the efforts of national legislation, efficient motor systems research and development, marketing and other aspects of the application, developed in electricity efficiency function at a high level. Electrical potential energy efficiency improvements, covers a wide, comprehensive and strong. Hopes to improve the organization and implementation of motor energy efficiency program, one can further improve the energy conservation policy standards, strengthening mechanisms and modes of innovation. On the other hand can promote motor manufacturing industry to upgrade and advance manufacturing power strategies to achieve green manufacturing. Meanwhile, the system sum up experience, but also for the subsequent organization and implementation of industrial boilers, combustion engine energy efficiency enhancement program to provide better reference. For screw compressor design: 1. rational design of the intake and exhaust pipes, dhl reduce pressure loss and leakage inside the tubes; 2. frequency control to achieve capacity adjustment, compared with the normal dhl intake throttle type, frequency Compressor energy savings of up to 30% to 40%; 3. Using direct-coupled motor, reducing mechanical transmission losses, while using dhl efficient permanent magnet synchronous motor. 4. The use of microcomputer control, reduce the magnitude of the load and unload dhl, to ensure the lowest gas equipment dhl pressure conditions, reduce exhaust pressure dhl setting; 5. Multi-unit control air compressor, air based on actual use dhl the amount is automatically selected necessary number of units dhl dhl air compressor machine price, thus avoiding unnecessary waste of dhl dhl huge multiple machines at the same time due to the operation. For screw compressors, its shortcomings are the following three points: 1. The high cost: screw compressor rotor tooth surface is a curved space, the need to use a special tool for processing on expensive special equipment. In addition, the screw compressor cylinder machining accuracy also have higher requirements. 2. Not suitable for high pressure applications: Due to the limitations of the rotor and the bearing stiffness and other aspects of life, can only be applied to the screw air compressor and low pressure range, the exhaust pressure is generally not more than 3.0Mpa. 3. Can not be made miniature: screw compressors rely clearance seal gas volume flow is greater than the current general only 0.2m3 / min, screw compressor that has the superior performance.
