> High efficiency three dimensional half open impeller: using the latest full three yuan flow channel design software, after the later CFD simulation flow field verification scheme, the vacuum pump efficiency is greatly improved.
> The high efficiency area is wide: using advanced pneumatic design technology, the high efficiency operation area of the impeller is widened more than 50%, so that the turbine runs efficiently under different working conditions, and the comprehensive energy consumption is low.
> The selection and processing of the impeller: the impeller is made of imported high strength stainless steel, which is made by the NC five axis machining center, which ensures the precision and strength of the impeller.
> Oil system design: the advanced finite element analysis software is used to analyze the overall stiffness of the oil station to ensure the reliability of the support. The oil system is equipped with an oil mist fan and the oil system operates under negative pressure, which effectively solves the problem of oil fumes and splashing of lubricating oil in gear boxes.
> Gearbox: the high speed shaft of the gear box adopts tilting pad bearing, with high stability. The gear processing reaches

> High efticiency three yuan dlosed impeller: the frst breakthrough in the industry of three yuan Ftosed impeller desion, processing difficulties, the three yuan closed impeller applied to multistage turbine products, the efficiency is more than two yuan impeller high 6-8%, the turbine energy consumption reduced by 6-8%.
> Integral steel base: main chassis and gear box adopt integral base design.Pre - assembly pre - assembly and pre assembly position are recorded on the base by the positioning pin in the 100% front of the factory, so as to ensure the installation accuracy of the site and shorten the site installation and commissioning period.
> Tilting bearing: use tilting tile instead of round tile. The tilting tile can swing freely with different speed, load and bearing temperature, forming multiple oil wedge around the axle neck, which has high stability. Bearing horizontal section, easy to repair. The stability is much higher than that of the round bearing. The whole machine runs stably and has low vibration. Balance plate: balance the thrust of the rotor with the pressure difference between the inlet and outlet of the turbine through the thrust plate, reduce the load of the thrust bearing, and improve the service life of the thrust bearing.
> Material: imported high strength stainless steel for impeller and heat treatment for many times during processing to ensure strength and corrosion resistance. The stainless steel bushing is used to prevent corrosion.
