Shockproof Compact rotary Screw Air Compressor Computer Controlled 7.5KW

Remarkable Air end:Germany original-builing GHH-RAND air end adopts the third-generator dissymmetrical gear shape.The main rotor is five gears and the vice rotor is six gears.As the
differences between them is small,the loss of circumfluence is small which increases the cubage
efficiency by close to 20% and save the electric currency by about 25% comapared to normal
screw air compressor.The rotor is dissymmetrical shape ,supported by ball bearing and rod bead
bearing and operating at a low speed so it can lower the mairtanance cost and provide the air
end with a longer service life

Gas Intake valve:Controlledby computer ,the stable and dependable air inlet control valve
can make the air displacement and power consumption of the motor chang along with the air consumption,so as to save energy and electrity ,and reduce the operating cost

Oil and air separator:Screw-shaped design of oil and gas separator is easy to uninstall and
change. Separator core can
separate the left oil in the process of compressing air. After separating ,the left oil will be
about 12 ppm. this will increase the cleanness of the compressed air and lower the pollution
to the compressed air and lower the pollution to the compressed air and equipment

Cooling system:The designed super large cool area ensures it working normally at high
temperature and hot environment. Good heat transfer performance, little flow resistance
and low request for water quality. It is convenient to clean and need no special cleaning fluid

Motor: Famous brand motor with F class isolation and IP54 protecting class. It uses imported
SKF durable bearing and can be operated all day long

Temperature Controller Valve:Designed specially for the high environment temperature and
high air humidity, upon cold start up, thermal valve enables the system to reach the best working temperature as soon as possible, and maintains constant temperature and viscosity of lubricant
to prevent condensing of evaporated gas and emulsification of the lubricant, which prolongs the
service life of the lubricant, rotor of the main machine,bearing and other part

3. Description:
♦ Fully seal & double screw,dual shockproof,smooth operation,can be installed anywhere.
♦ With a exquistie shape and compact structure and cover a small area.
♦ Large displacement,stable pressure and high efficiency.
♦ Low exhause temperature (only 7 °C~10°C higher than the ambient temperature)
♦ Safe,liable,smooth operation,little noise and long maintenance cycle and using life.
♦ The intelligent control system completely satisfy the continuous cooperation without man work.
♦ Many screw air compressors operate together and start or shut down automatically
according to the air amount,and no man-work is needed.
♦ It is more energy saving for a single compressor can adjust air demand automatically according
to the users' air amount(frequency conversion type).
♦ The degree of tightness of the belt can be auto-matched with the flexible belt. Through adjusting the tensility, the loss of the pressure and efficiency
can be reduced to the lowest point and increase the time efficiency of pressing.
♦ Narrow belt has higher transmission power with efficency of about 98%.the structure can reduce
internal heat and prevent aging. It enjoy Longer service life and much lower stretch ability.

4. Specifications:

     Kaishan group 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, Kaishan group 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.
"Kaishan" trademark, together with its logo, is the first company awarded with "Chinese renowned trademark" in the same trade and Kaishan 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. Kaishan group has been honored with "Special Quzhou Mayoral Award" for the past consecutive eight years.
Kaishan group has a sophisticated national-wide retail network supported by the high-quality customer service system. The nine major series of Kaishan 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, Kaishan group 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.
Kaishan group 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, Kaishan group sticks 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 Kaishan group the first in the industry which owns the intellectual property, core technique and competitive advantage among large-scale equipment manufacturers in China. In 2006, Kaishan group 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: Zhejiang Kaishan General Machinery Co., Ltd to the share market. Also, we are hoping to develop Kaishan group 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.
