The innovation and key technologies
Cleeson Industrial Park in Shanghai set up R & D centers and experimental center, to create the industry experienced professional R & D team continues to lead the development trend of the screw extruder technology to give new impetus to the world screw technology innovation, transformation and development drive to save energy.
1) The first generation of the new silent double helix host male and female rotor gear ratio of 5:6, up the tooth profile parameter equation of the arc, the arc envelope, cycloid, point, oval optimized combination of programs relative to the composition of the adjacent two sections of the tooth curve transition to impose slope of the tangent at the connection point to 0.02mm ~ 0.035mm high precision and uniform tooth profile space work space, and covering 1 to 84.2 cubic screw extruder.
2) the toothed adjacent two sections composed of tooth curve of a smooth transition at the connection point, the line of contact of the rotor is short, small leak triangular, large flow area, was streamlined, aerodynamic drag, low specific power, you can get a higher efficiency. Interdental area utilization factor, make full use of the volume of the rotor teeth, small aspect ratio, and enhance the rigidity of the rotor, streamlined design increases the flow area of the intake and exhaust openings, the greater trochanter low speed, lower noise, longer life.
3) the use of 45 high-quality carbon steel, quenched material has good microstructure and mechanical properties of the tooth surface hardness of HB200 ~ 240, good abrasion resistance. The spiral tooth surface efficient rotor precision grinding, milling semi-finishing yoke together generating method grinding engagement along the spiral public rotor and screw mother rotor pitch circle zero on contact with the high-pressure side space. Body using multi-axis machining centers batch processing, combined with top high-precision coordinate testing equipment, access to the most sophisticated smooth space meshing clearance.
4) The host is the best combination of imported bearings, high-precision cylindrical bearings paired penalty bearing positioning, effectively ensuring the rotor bearing lubrication during operation of high-precision positioning of the axial, radial; circulating oil lubrication, and through cycle oil movement away heat generated, high-strength load-bearing design able to withstand the load pressure of 17bar wider range of applications.
5) The type of compressor group unique design combined with advanced intelligent control system; the independent modular drive device, hot and cold room systems, air duct system, improve the a compression cooling efficiency; filtration and separation systems, high efficiency and precision of joint control adjust valve control, efficient operation; intelligent man-machine interface of the culture available on-line, remote monitoring, personalized programmable, and has a powerful fault diagnosis alarm and interlock protection, maintenance, operation more convenient and efficient use of atmospheric resources to achieve comfortable green product-oriented, and constantly save energy for sustainable production of power source.
6) diagnostic alarm and interlock protection, maintenance, operation more convenient and efficient use of atmospheric resources to achieve a comfortable green product-oriented, sustainable production of power sources continue to save energy.
7) unique within the oil duct design allows sprayed into the constant cooling lubricants play a role close to the ideal state isothermal compression, the effective compression ratio to ensure high efficiency.
8) Every head in strict accordance with the testing standards, undergo a rigorous resistance machine factory testing. The host of the series continue to design updates any special requirements or more detailed technical information, please contact our sales engineers.
Second, the main key technologies
Major R & D content of the project involved the design and development of the spiral host, host rotor profile design, rotor tooth profile design and processing, the whole filter separation system, hot and cold rooms, air duct system design. Has obtained high-precision space Helical Gears efficient conjugation generating method "(Patent No. ZL201010568544.X) invention patents," a high-precision spiral host rotor "(Patent No. ZL201020636601.9), a positive displacement spray oil twin-screw air compressors host "(Patent No. ZL201020636603.8), a spiral host rotor" (Patent No. ZL201020636598.0) and a twin-screw air compressor head (Patent No. ZL201020636606.1) utility model patents authorized.
On December 2, 2011, applications for invention patents spiral tooth profile, high-precision space efficient conjugation generating method, Patent No. ZL201010568544.X, on the the project host rotor helical profile design protection in 2012 October 3 authorized;
