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 motor energy efficiency for each one percentage point increase, annual savings of more than 260 one hundred million kwh of electricity; 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. Screw compressors with high reliability, easy operation and maintenance, power, good balance, adaptability advantages, become the preferred source of wind on mine drilling rig equipment and slag, involving manufacturing difficulty (screw compressor rotor tooth surface is a curved space, the need to use a special tool for processing on expensive special equipment, its high pressure casting cylinder machining accuracy also have higher requirements) and market quantity (restricted rotor stiffness and bearing life and other aspects of the decision The reason can not be made miniature) of the localization rate is not high, the majority of domestic drilling equipment also matching the price is more expensive imported screw compressors. According to the conditions analysis and practical experience of the screw compressor, enables early detection of hidden faults and timely maintenance and avoid failures scrapped, a single device can save parts costs several hundred thousand dollars. Screw compressor works: 1. Intake Process: When the rotor rotates, the yin and yang of the rotor tooth groove space at the inlet end wall opening to go, its largest space, then the rotor tooth groove space communicates with the inlet, tooth groove because gas is completely discharged when the exhaust, the exhaust is completed, tooth groove in a vacuum, when the go to the air intake, outside gas inhalation i.e., axially into the yin and yang of the rotor tooth groove. When the gas filled the tooth groove, the rotor inlet side end face turned away from the air inlet compressor housing prices, he incurs the gas enclosed in the tooth groove. 2. Compression Process: yin and yang, breathing air compressor rotor at the end of the brand, its sharp teeth with the yin and yang of the rotor housing is closed at this time no gas in the tooth trench drain. Its engaging surface gradually moves towards the discharge end. Meshing tooth groove space between the surface and the exhaust port gradually becomes smaller compressor Qin Wei, tooth trench increase pressure gas is compressed. 3. Exhaust process: When the engagement end surface of the rotor and the casing to the air outlet, the compressed gas begins to discharge, until the engagement surface of the tooth tip and the tooth groove moved to the end face of the exhaust gas, then the male and female rotors engaging surface and cabinet exhaust port tooth groove space is 0, i.e., the exhaust process is completed, at the same time the length of the engagement surface of the tooth groove of the housing of the rotor between the air inlet and the longest, the intake process is carried out again . Screw air compressor, air compressor Cottle Qin Wei European markets synchronous technology (certified), the compressor is provided by Compressor Co., Ltd., Xianyang Qin Wei. Xianyang Qin Wei Compressor Co. (www.qwkyj.cn/) is Xianyang, compression, separation equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
