Shashi air compressor maintenance of price / Shashi good air compressor which can Compressor Co., Ltd. Shanghai Yi Spec 24-hour sales hotline: 17,717,607,785 new generation of high efficiency screw rotor 1, independent research and development and production of the third generation of U Series host, using a new tooth that is the double helix host male and female rotor gear ratio of 5: 6, consisting tooth profile parameter equation for the arc, arc envelope, cycloid, ellipse optimal combination of solutions, two adjacent tooth curve segments tangent slope transition junction sentenced to obtain high accuracy 0.02mm-0.035mm and uniform tooth profile space work space. 2, adjacent teeth tooth curve smooth transition at the connection point, the rotor contact line short, leakage small triangle, flow area, was streamlined, low aerodynamic drag, low specific power, can obtain higher power two stages. Larger interdental area utilization coefficient, make full use of rotor teeth volume, long-necked smaller than enhance the rigidity of the rotor, streamlined design flow area increases the amount of intake and exhaust openings, large rotor low speed, lower noise and longer life. 3, using imported high-quality carbon steel, after quenching, the material has good microstructure and mechanical properties, high tooth surface hardness. Reach HB200-240, good abrasion resistance, helical rotor surface using efficient Japanese precision grinding and milling were semi-finishing, the high-pressure work well along the spiral rotor and female rotor pitch circle of the helical gear together with the zero-for-zero-touch side space conjugation generating method grinding. Body is made of multi-axis precision machining center batch processing, combined with top high-precision coordinate testing equipment, access to the most sophisticated smooth space backlash. 4, the host using the best combination of imported bearings, precision bearings matched four penalty cylindrical bearing position, effectively ensure the rotor during operation of the axial, radial high-precision positioning; bearing lubrication circulating oil lubrication, and by heat, high strength load bearing design cycle oil away movement, and able to withstand the load pressure 17bar wider range of applications. 5, the unique design allows the internal oil passage is injected into the cooling lubricants play a constant role. 6, according to the Chinese Academy of Science and Technology issued Chaxinbaogao show, the host products with independent intellectual property rights of high-efficiency energy saving can be achieved, a number of innovations, integrated technology has reached the international advanced level.
