Silk LGCY Two-stage Compressed Diesel Movable Screw Air Compressor

At present, Silk screw air compressor product energy efficiency level has been in the world's leading level. In addition to advanced profile technology, we also have global invention patents to ensure lower fuel consumption. If you compare our products with similar foreign products, you will soon find that the fuel savings of our products are very obvious. The advancement of technology is self-evident, and the reliability has already been proved by hundreds of units in service.

Design Characteristics of Screw Rotor Profile:

1. It fully realizes "Convex-Convex" engagement to assist in the formation of hydrodynamic lubrication film, to reduce horizontal leakage passing the contact zone, and to improve efficiency of the compressor; improve rotor processing and testing property.

2. It adopts the design thought of "large rotor, large bearing and low speed method", thus its revolving speed is 30-50% lower than that of other brands to reduce noise, vibration, and exhaust temperature, improve rotor rigidity, increase service life, and reduce sensibility to sundries and oil carbide.

3. Its power range is 4~355KW, where 18.5~250KW applies to the compressor without direct-coupled gearbox, 200KW and 250KW apply to the compressor with Level 4 direct-coupled motor and the speed is as low as 1480 rmp.

4. It fully conforms to and exceeds requirements in GB19153-2003 Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation of Capacity Air Compressors.

We also have drilling rig, jack hammer, drill rod and other related products.

    Silk Road is a state-level large scale enterprise in China, which has been listed among the five industries of Zhejiang Provincial government, the 958 Technology Catching-up Plan and the key enterprises by Zhejiang provincial government. The group is the civilized enterprise of provincial level and contract abiding and trustworthy enterprise of state level.
Currently, Silk Road has 18 subordinate companies with over 4100 employees. It covers an area of over 430,000 m2 with the total building complex area over 230,000 m2 and the total assets of the group amounts to over 1.5 billion.
"Silk Road" trademark, together with its logo, is the first company awarded with "Chinese renowned trademark" in the same trade and Silk Road air compressor is among the first exempted by Chinese government.
By the year of 2008, the total sales revenue of the group is 2.03 billion RMB, with 173 million RMB of profit, and USD10.69 million worth of export goods. Silk Road has been honored with "Special Quzhou Mayoral Award" for the past consecutive eight years.
Silk Road has a sophisticated national-wide retail network supported by the high-quality customer service system. The nine major series of Silk Road product spread from rock drilling unit, screw air compressor to excavator, crawler drill etc, and altogether 18 categories with over 800 individual products.
By far, Silk Road is the largest rock drill manufacturer in the world, and the largest air compressor manufacturer in China. Exports are shipped to over 20 different nations and regions such as United States, Germany, Japan, South Korea, Russia, African and Latin American countries.
Silk Road owns the best fine processing equipment over 1000 units. It has formed the machinery processing system with advanced technology, top-rate equipments and structure integrity.
In recent years, Silk Roadsticks to the talent-employment standard of Capable, Tough and Reliable and upholds the enterprise spirit of Flexible, Efficient, and Confident. Focusing on technology and industry innovation and centering product and market restructuring, the group have already planned a "4211" development strategy.
In 2005, cooperating with Xi'an Jiaotong University compressor research institute and interlinking with the state 863 project, the group successfully developed a high-tech product: screw air compressor's core part : screw rotors . It marks the end of relying on import this unit from overseas only in China. The success has made Silk Road the first in the industry which owns the intellectual property, core technique and competitive advantage among large-scale equipment manufacturers in China. In 2006, Silk Road was awarded with a second-class outstanding technique invention award by Chinese government for this technology.
Upon the success, we are currently trying to list one of our subordinate company: Silk Road to the share market. Also, we are hoping to develop Silk Road into a large-scale and diversified manufacturer with its own patent core technique and core competitiveness. We are striving to rejuvenate our national industry and develop as the pillar of Chinese air compressor industry in a yearning for greater contribution to China's harmonious society construction and national equipment manufacturing industry development.
