Vacuum pump

Aqueous vacuum is a liquid ring pump, a positive displacement pump, commonly used as a vacuum pump, but can also be used as a gas compressor. The performance of a liquid ring pump is similar to that of a rotary pump, except that the edges are an integral part of the rotor and tighten a liquid rotation ring to create a compression environment. The rotor is the only moving part. Liquid ring pumps are usually designed by an induction motor.

Water vacuum pump Rotates an outlet impeller outside the center into a cylindrical cover, the liquid (usually water) enters the pump and covers the centrifugal force of a removable cylinder ring. . This liquid loop creates a closed space between the edges of the impeller that forms the compression chambers. The instability between the axis of rotation of the flywheel and the geometrical axis of the coating results in cyclic changes of the volume enclosed by the blades and rings.

Gas, often air, is drawn into the pump through the inlet valve at the end of the cylinder. The gas is trapped between the blades and the liquid rim. The volume reduction caused by rotation of the impeller compresses the gas accumulated at the end of the cylinder.

Liquid ring vacuum mappings, which are often used as liquid ring water, are used in the vacuum autoclave system and are known as the blue vacuum pump. Blue vacuum pumps are divided into two categories: two-stage blue vacuum pump and one-stage blue vacuum pump.

1-1. Two Stage Liquid Ring Vacuum Pump

The two-stage aqueous vacuum pump consists of two impellers and two cylinders that are interconnected through gates and increase the suction power of the vacuum pump.

2-1. Single Stage Liquid Ring Vacuum Pump

The one-stage aqueous vacuum pump consists of a impeller and a cylinder used in autoclave aqueous vacuum pumps with low-tolerance brass impeller.

1-2. Two stage oil rotary vane vacuum pump

Oily vacuum pumps used in autoclaves can reduce vacuum pressure by up to 10 * 3 millibars.
