High Speed Vacuum Pump with Gas Foils

Product Description

Core technology
Air Suspension Bearing
·Full dynamic pressure air suspension, without the need for an external air source, relies on the high-speed rotation of the rotor to form a compressed air film support between the shaft and the bearing foil, that is, to form an air film lubrication, resulting in low losses during high-speed rotation.
·The bearing structure is simple, reliable, with high load-bearing capacity and good dynamic characteristics, which can effectively suppress rotor vibration· After more than 50000 start stop tests, the surface coating has good durability and is a true semi permanent life bearing.
High speed permanent magnet motor
·The permanent magnet rotor structure has high efficiency in the full speed operation range, with a maximum efficiency of over 97%.
·Speed above 25000rpm.
·High frequency speed regulation, anti reverse start.
·The motor is coaxial air-cooled, without the need for an external cooling fan, making it simple and reliable.
Efficient centrifugal impeller
·Three element flow and rear bending design, precision machining with a five axis machining center, achieving a variable efficiency of over 92%.
·Using high-strength materials (7075 aluminum, titanium alloy, 630 stainless steel, etc.), with additional surface coatings for greater wear resistance and stability.
·Tested through 115% overspeed test.
Intelligent control of the whole machine
·PLC based whole machine control, touch screen interface, simple and easy-to-use interaction.
·Equipped with an internal venting device to ensure safe shutdown of the fan during no-load start-up and fault situations.
·Implement anti surge protection, accurately identify surge, and automatically shut down for protection before surge faults occur.
·Equipped with remote IoT functionality, it can achieve various controls such as remote and on-site, centralized and standalone.
