Medical vacuum system

The negative pressure suction system is composed of central suction station, pipeline, valve and terminal equipment. The vacuum suction machine room is an independent operation room. The negative pressure source of the central suction system is that the vacuum unit of the central suction machine roo...

Model 2020 is now mass produced - quality is improved again (single-stage rotary vane vacuum pump)

From March 2020, our company officially put into the new pump body material, improve performance.     ...

How Roots Vacuum Pump works

The Roots vacuum pump is a vacuum pump without internal compression. Usually, the compression ratio is very low, so the high and medium vacuum pumps need the foreline pump. A vacuum pump that realizes pumping by moving a gas by a pressing action of a pair of leaf-shaped rotors in a pump chamb...

How to use Single-Stage Rotary-Vane Vacuum Pump

1. Before use, carefully read the product instruction manual and check the shipping quality after unpacking. Collect spare parts and technical documents and remove the exhaust guards. Install, wire and test steering as required. 2. In order to prevent oil injection due to oil return and...

How does the water ring vacuum pump work

Before starting, the water ring vacuum pump body is filled with an appropriate amount of water as the working fluid. When the impeller rotates the brick, the water is thrown around by the impeller. Due to the centrifugal force, the water is pumped to the wall of the pump body to form a closed...

Structural features of the Roots vacuum pump

(1) A large pumping speed over a wide pressure range; (2) The rotor has good geometric symmetry, so the vibration is small and the operation is stable. There is a gap between the rotor and between the rotor and the casing, no lubrication, and the friction loss is small, which can greatl...

Vacuum unit working principle

The working principle of the vacuum unit: a vacuum pump that pumps the gas by moving the gas in a synchronous and reverse rotation of a pair of leaf-shaped rotors in the pump chamber. The Roots vacuum unit is a mechanical vacuum pump with a pair of synchronous high-speed rotating sole-shaped ...

Vertical oil-free vacuum pump Features

(1) The power consumption is small, and the energy saving effect is obvious; (2) Small footprint and low working noise; (3) The cylinder adopts forced water cooling, and the cooling effect is good; (4) Adopting a sealing structure to reduce the occurrence of phenomena such a...

Water ring vacuum pump selection

Pump type determination The type of pump is mainly determined by the amount of air, vacuum or exhaust pressure required for the job. When the pump is working, you need to pay attention to the following two aspects: 1. As far as possible, operate in the high efficiency zone, ...
