Component-Replaceable Water Ring Vacuum Pump Head Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water ring vacuum pumps have integral head units, making it difficult to replace inner components without disassembly, leading to issues like gas and liquid leakage, increased operation time, and safety risks.
Innovation Solution
A prefabricated water ring vacuum pump design with a detachable bearing bracket and caps allows for the replacement of inner components like the guide bearing and mechanical seal without separating the head unit from the main body, using a bolt-fastened bearing bracket and seal fastening bolt to maintain airtight conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the head unit has an integral structure, then the structural strength and sealing are improved, but the ease of replacing inner components deteriorates
Solution Approach 1:
The head unit is divided into multiple detachable sections: a front casing, a rear casing, and an intermediate casing. The intermediate casing can be separated from the front and rear casings to provide access to inner components like the guide bearing and mechanical seal, while the front and rear casings remain connected to maintain structural integrity and sealing during operation.
2Ease of repair
If the head unit is disassembled to replace components, then the ease of replacing inner components is improved, but the operation time and risk of leakage increase
Solution Approach 1:
The intermediate casing is designed as a separate removable section that provides direct access to the guide bearing and mechanical seal. This allows maintenance personnel to replace these components without disassembling the entire head unit or separating the front and rear casings, significantly reducing operation time and minimizing the risk of gas or liquid leakage during maintenance.
Applied Scientific Principles

AI summary
Disclosed is a component-replaceable water ring vacuum pump in which inner components within a head unit may be disassembled and replaced without separation of the head unit from a main body, thus shortening an operation time and improving operation efficiency through prevention of leakage of an inner liquid during a replacement process. The water ring vacuum pump includes a main body provided with a shaft, a rotor rotated together with the shaft within the main body, a head unit coupled to both sides of the main body, a guide bearing provided within the head unit, and a mechanical seal configured to block inner gas. A bearing bracket to support the guide bearing is detachably fastened to one side of the head unit by a bolt, and an inner cap and an outer cap are assembled to the inner and outer surfaces of the bearing bracket by fixing bolts.
