Abstract

The invention discloses a liquid ring roots vacuum unit, which is characterized by comprising a roots pump and a liquid ring pump, wherein the bottom end of the roots pump is provided with an air inlet, a filtering device is arranged in the air inlet, a rotor and a shaft I are arranged in the pump cavity of the roots pump, the middle part of the rotor is provided with the shaft I, the bottom of the roots pump is provided with a vent port I, the roots pump is connected with the liquid ring pump, a control device is arranged between the roots pump and the liquid ring pump, a liquid ring, a shaft II and an impeller are arranged inside the liquid ring pump, the shaft II drives the impeller and the liquid ring to rotate, and the top end of the liquid ring pump is provided with a vent port II. The liquid ring roots vacuum unit has the advantages that the roots pump is combined with the liquid ring pump, so that high efficiency and energy conservation can be realized, the structure is compact, the vacuum degree is high, and the discharge capacity is large; and by setting a charcoal filter layer, the absorbed air is more clean, the liquid ring roots vacuum unit is applicable to the vacuum drying, petroleum chemical industry, metallurgy and chemical fiber industry, and the application range is wide.

Description

Technical field [0001] The invention relates to a vacuum pump, in particular to a liquid ring roots vacuum unit. Background technique [0002] Roots vacuum pumps are widely used in smelting and degassing, rolling, chemical, food, medicine and other industries in vacuum metallurgy. They are widely used. Traditional roots vacuum pumps will have some problems in the working process. The vacuum degree is low. A single roots vacuum pump has a small displacement and is not suitable for the requirements of enterprises. [0003] Therefore, in order to solve the above problems, a new technical solution is provided to meet the demand. Summary of the invention [0004] The purpose of the present invention is to provide a liquid ring roots vacuum unit. [0005] The technical scheme adopted by the present invention is: [0006] The liquid ring roots vacuum unit includes a roots pump and a liquid ring pump. The bottom of the roots pump is provided with an air inlet, the air inlet is provided with ...
