Oil-lubricated screw vacuum pumps

Oil-lubricated screw vacuum pumps represent a sophisticated vacuum system technology used in a wide range of industrial applications. These systems are designed to provide reliable and efficient vacuum generation using rotating screw spindles.

Oil lubrication plays a key role in the operation of the vacuum pumps - not only does it reduce friction and wear and tear, it also serves as a sealing medium and filter to trap contaminants. Combined with advanced control systems such as Variable Speed Drive (VSD), these vacuum pumps offer high efficiency and adaptability, thus meeting the requirements of specific applications while minimizing energy consumption.

In these vacuum systems, oil is not only used as a lubricant, it also helps to seal the gap between the spindle lobes and the wall, thus improving heat dissipation and helping in trapping contaminants. Innovative technology enables speed control. It can automatically adapt to changing vacuum requirements, while increasing energy efficiency and reducing the equipment wear and tear.

The principle of vacuum creation

The vacuum pump has two spindles installed in a parallel way - one is fixed and the other rotates. These spindles are mutually synchronized by the means of a gearbox, but they do not touch each other or the walls of the vacuum pump. As the spindles rotate, air molecules are trapped and moved between the spindle lobes and the chamber walls.

As the spindles rotate, air is drawn into the vacuum pump, trapped between the lobes and diverted to the output. This cycle reduces the number of air molecules in the vacuum chamber, creating a vacuum.
