Liquid feeding type screw compressor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed compressor arrangements, the high center of gravity due to large and heavy motor and compressor units leads to increased vibration and noise, while also requiring significant installation space.
Innovation Solution
A liquid feeding type screw compressor design where the motor is positioned above the compressor main body, and a gas-liquid separator is placed below, with an integrally molded casing that includes both components, enhancing rigidity and reducing the need for additional connecting elements, thus lowering the overall size and weight while improving vibration and sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the motor and compressor unit are arranged above the pressure container to reduce installation space, then the floor space is reduced, but the center of gravity becomes high causing increased vibration and noise
Solution Approach 1:
The patent merges the compressor main body casing and the pressure container into a single integrally molded casing structure. This integration allows the motor and compressor to be positioned above the pressure container while the unified casing provides enhanced structural rigidity and vibration absorption, thereby reducing noise and vibration despite the high center of gravity configuration.
Solution Approach 2:
The integrally molded casing is constructed as a composite structure combining the compressor main body casing and pressure container as one unit. This composite design improves overall structural rigidity and creates a more stable base that mitigates vibration and noise, even when heavy components are positioned overhead.
2Area of stationary object
If the motor and compressor unit are arranged above the pressure container, then the installation space is reduced, but the structural rigidity and stability are compromised
Solution Approach 1:
The compressor main body casing and pressure container are merged into a single integrally molded casing, creating a unified structural unit. This integration significantly enhances the overall rigidity and stability of the compressor system, providing a more stable base that can support the motor and compressor positioned above the pressure container.
3Ease of manufacture
If separate casings are used for the compressor main body and pressure container, then the ease of manufacture is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines the compressor main body casing and pressure container into a single integrally molded casing structure. This merger reduces the total number of separate components and assembly steps, thereby simplifying the overall device structure and reducing complexity despite maintaining manufacturing feasibility through integral molding techniques.

AI summary
There is provided a liquid feeding type screw compressor that can reduce size and weight and improve vibration insulation and sound insulation. A liquid feeding type screw compressor includes as components: a compressor main body; a motor driving the compressor main body; and a gas-liquid separator separating a liquid from a compressed air discharged from the compressor main body. The motor is arranged above the compressor main body. The gas-liquid separator is arranged below the compressor main body. A compressor main body casing constituting an inner cylindrical space forming a compression operation chamber together with the screw rotor and constituting the contour of the compressor main body and a casing constituting the contour of another component consist of an integrally molded single member.
