Vacuum Pump
A vacuum pump is a mechanical device designed to create negative pressure and evacuate air or gas from a sealed environment. Typical suction capacity ranges from 50 to 1000 liters per minute, with achievable vacuum pressure from 0.1 to 0.001 bar. A 0.5 to 7.5 kilowatt electric motor or a small diesel engine powers rotor rotation. The rotor is made of hardened steel or aluminum alloy with wear-resistant coating. The cylinder and internal chamber are constructed from stainless steel or die-cast aluminum for durability and corrosion resistance.
Structurally, the vacuum pump includes a rotor or screw impeller, mechanical or graphite sealing system, and standard inlet and outlet connections. Special oil or grease lubricates and reduces internal friction. Device weight ranges from 30 to 500 kilograms and can be mounted on a steel base or wheeled chassis. Continuous operation is guaranteed in temperatures from 0 to 50°C, with compatibility for chemical, medical, and packaging industries.
