Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for vacuum pump sets, specifically a vacuum pump gas-water separation device. Background Technology

[0002] A vacuum pump gas-water separator is an auxiliary device installed at the front end of the vacuum pump inlet. Its core function is to efficiently separate, intercept, and remove liquid water, water mist, condensable vapor, and other impurity droplets carried in the gas extracted by the vacuum system from the gaseous working medium through physical methods. This prevents these harmful media from entering and damaging the vacuum pump. It is a key protective component that ensures the stable operation of the vacuum pump and extends its service life. The above-mentioned vacuum pump gas-water separator is an example.

[0003] Some vacuum pump gas-water separation devices use multi-stage adsorption filter elements to intercept and separate gas and water. However, the main body of the device generates noise when intercepting and separating gas and water. The above-mentioned vacuum pump gas-water separation devices have poor noise reduction effect, resulting in external noise generated when the vacuum pump gas-water separation device intercepts and separates gas and water. Therefore, a vacuum pump gas-water separation device is proposed to address the above problem. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum pump gas-water separation device to solve the problem that the vacuum pump gas-water separation device mentioned above has poor noise reduction effect, resulting in external noise generated when the vacuum pump gas-water separation device performs gas-water separation and interception.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vacuum pump gas-water separation device includes a tank shell, a tank core, and an automatic drainer. The tank core is disposed inside the upper part of the tank shell, and the automatic drainer is disposed at the bottom of the tank shell. A flange is fixedly connected to the outside of the automatic drainer. The tank shell includes a housing, a first asphalt damping plate, a first vibration-damping silicone layer, an annular disc, a first retaining ring, a second retaining ring, a silicone ring, a drain pipe, and an air inlet pipe.

The captured tiny droplets are initially dispersed on the fiber surface. As the process continues, more droplets are captured, and they gather and merge at the fiber intersections or surfaces, gradually forming larger droplets. Subsequently, under the action of gravity sedimentation, they drip and collect, settling in the [unclear - possibly a specific location or environment].
