Vacuum pump is a large and wide range of products, with large output and low output value, but it is indeed an indispensable basic product that directly affects the performance and quality of vacuum equipment. Vacuum pump is a kind of pump which is common and commonly used in many pump products. It is a kind of device that improves, produces and maintains vacuum through mechanical, physical, chemical or physical chemical methods in a closed space. It is widely used in metallurgical, chemical, food, electronic coating and other industries. So 2BV water ring vacuum pump and centrifugal pump What are the differences?

Liquid Ring Vacuum Pump China

Centrifugal pump works by centrifugal movement of water caused by impeller rotation. Before starting, the pump shell and suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and water to rotate at high speed, water centrifugal movement occurs, which is thrown to the outer edge of the impeller and flows into the pump's pressure pipeline through the flow channel of the volute pump shell.Single Stage Liquid Ring Vacuum Pump And Double Stage Liquid Ring Vacuum Pump

Vacuum pump has simple structure, low manufacturing accuracy and easy processing. Compact structure, high speed pump, can be directly connected with the motor, without the need for deceleration device. Therefore, with a small structure size, we can get a large amount of exhaust gas and occupy a small area. Compressed gas is basically isothermal, that is, the temperature change of the compressed gas process is very small. Because there is no metal friction surface in the pump chamber, there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal. Inhalation uniformity, stable and reliable work, simple operation, easy maintenance.Roots vacuum pump Rotary Vane Vacuum Pumps

The centrifugal pump has a compact structure with a wide range of flow and head. It is suitable for mild corrosive liquids. Various control options have the advantages of uniform flow, stable operation and small vibration. No special base for shock absorption is required. Equipment installation, maintenance and repair costs are low.rotary vane vacuum pump

The above is about the difference between water-ring vacuum pump and centrifugal pump. Generally speaking, centrifugal pump pumps liquid without solid particles. Water-ring vacuum pump is a kind of coarse vacuum pump, which pumps no corrosive gas and water vapor. The two pumps have completely different uses.Water ring vacuum pump
