Original Designs and Innovations
Features
· Advanced technology, adopting advanced the fifth generation of compound variable pitch screw technology.
· Environmental friendly, no-oil (oil free), no-water, non-pollution, clean vacuum.
· The gas pumped can be recycled, applying for oil and gas recovery, solvent recycling and special gas recycling.
· Energy-saving technology with variable pitch, reducing energy consumption by 30%.
· PTPE coating, enhanced chemical corrosion resistance greatly.
· Air-cooled structure, easy to operate.
· Operating pressures from atmospheric pressure to ultimate vacuum pressure.
· Saving manpower, longer maintenance intervals of up to ten thousand hours.
· Easy to clean, if the dirt enter pump chamber, it can be filled with the gas or cleaning agent to cleaning.
· Reliable sealing structure, use of a lip seal, mechanical seal and a gas seal structure, exhaust smooth, with good fluid-handling capabilities.
· Light weight, using new lightweight materials.
· Low voice and vibration, using high precision parts.
· Low temperature rise, due to we use the new materials, and heat faster.
· Shockproof prevent design, it can be placed on the ground directly.
Principle
Dry compound screw vacuum pump are consist of two paralleled screw rotors and pump body form multiple sealed space, rotor and rotor, rotor and pump body all keep minuscule clearance(no touch, no friction), with the reverse gears driving, gas keep continuously transfer from inlet hole to outlet hole. Due to two rotors and pump body have no friction each other, need not lubrication oil, can keep clean gas. Gas keep continuously transfer, short passageway, high efficiency, outlet hole position lower than screw rotors, strong drainage ability, easy to clean, no intermediate bulkhead(claw vacuum pump and rotors vacuum pump have intermediate bulkhead), better exhaust and drainage, easy to maintain.
