• This rotor profile resolves the interference issue common in conventional involute rotors, resulting in more uniform rotor clearances and enhanced sealing performance between the rotors.
• Compared to the two-lobe rotor, the three-lobe rotor not only improves the area utilization rate by 8.5% but also boosts the meshing overlap by 12%, resulting in smoother meshing and more stable exhaust performance.
• The dynamic balancing characteristics of a three-lobed rotor are superior to those of a two-lobed rotor, with higher stiffness and strength, enabling it to handle significantly higher rotational speeds.
• The clearance between the three-lobed involute rotors is more uniform and fixed, resulting in improved sealing performance. This leads to significantly reduced pump leakage, allowing the pump to handle a much larger pressure differential across the inlet and outlet ports—and enabling higher backpressure as well.

Precision Machining
The forged billet is turned by a CNC lathe to remove most of the allowance, making the shape of the rotor closer to the design size, while leaving an appropriate machining allowance for the subsequent fine processing. The precision machining of the screw profile is carried out using a MAZAK precision machining center. Through precise programming and processing, the profile accuracy of the screw rotor is controlled within the design requirements.
Assembly
After the installation engineer checked the vacuum pump materials, they assembled the vacuum pump products in accordance with the drawing requirements and conducted pressure tests and usage debugging on the assembled vacuum pump products.
Quality inspection
After each processing step of the product is completed, the quality inspection team conducts quality checks based on the processing technology and product standards. Products that do not meet the standards need to be reworked or scrapped.
Shipment
After all processing procedures are successfully completed, the staff responsible for packaging and shipping will check each product against the shipping documents one by one. Once the information is accurate, they will contact the logistics to arrange for shipping.
Experience accumulation
Focused on vacuum systems for 16 years, with deep industry experience and highly specialized manufacturing expertise.
