Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Roots pumps have limitations in installation options, pumping capacity, and geometry of the suction and discharge flanges, which hinder their versatility and efficiency.
Innovation Solution
A redesigned housing for Roots pumps with 90° angled fastening elements, asymmetrical cooling ribs, and adaptable flange designs for ISO and DIN connections, allowing for versatile mounting, improved heat dissipation, and optimized energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard mounting configurations are used, then the pump structure is simple, but installation options are limited
Solution Approach 1:
The housing incorporates multiple mounting configurations (feet, flanges, brackets) that enable the pump to be installed in various orientations (horizontal, vertical, inclined) and positions, making a single housing design serve multiple installation purposes and reducing the need for separate mounting components
2Productivity
If symmetrical flange geometry is used, then manufacturing is simple, but pumping capacity is limited
Solution Approach 1:
The suction and discharge flanges are designed with asymmetric geometries optimized for their specific flow directions and pressure conditions, allowing larger opening areas and better flow patterns that increase pumping capacity, while remaining manufacturable using standard machining processes
3Area of stationary object
If vertical mounting is used, then space utilization is improved, but shearing forces act on mounting screws
Solution Approach 1:
The housing provides multiple mounting interfaces including side-mounted flanges and adjustable brackets that allow the pump to be securely mounted in vertical, horizontal, or inclined positions, enabling space-saving vertical installation while distributing mounting loads through appropriately oriented fastening surfaces

AI summary
The invention relates to a housing for a rotary lobe pump with an inlet flange and an outlet flange, - in which cooling fins are arranged on an outside of the housing, in which the number of cooling fins in the area with a higher internal pressure is greater than the number of cooling fins in the area with a lower internal pressure, - in which a cross-section of the inlet is larger than a cross-section of the outlet, - in which the flanges have a polygonal cross-section with at least two opposing sides arranged parallel to each other, or - in which the housing has fastening elements consisting of mounting surfaces and a connecting surface.
