Tank-Mounted Hydraulic Pump Modules for Low-Loss Fluid Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic pump systems in working vehicles are inefficient due to energy losses in long piping and require complex maintenance, especially when driven by internal combustion engines, leading to unnecessary energy consumption and reduced efficiency.
Innovation Solution
A hydraulic pump system with self-contained pump modules mounted directly to a housing within a tank, reducing piping length and allowing for independent control of each pump module via electric motors, which can be easily installed, removed, and maintained, and are designed for compactness and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the hydraulic pump is provided separate from the tank with long piping connecting them, then the pump can be independently positioned, but energy losses increase along the piping length
Solution Approach 1:
The pump is merged with the tank by mounting the pump directly to the tank wall, eliminating the need for separate piping connections. This integration reduces energy losses along piping length while maintaining independent pump positioning capability through the mounting bracket assembly.
2Use of energy by moving object
If the hydraulic pump is driven by an internal combustion engine, then the pump operates whenever the engine runs, but unnecessary energy consumption occurs when hydraulic fluid flow is not required
Solution Approach 1:
The pump system transitions from static ICE-driven operation to dynamic electric motor control, where the pump operates only when hydraulic fluid flow is actually required. The electric motor can be controlled independently of the ICE, enabling on-demand operation that matches actual hydraulic system needs.
3Ease of repair
If the pump is mounted separately from the tank, then installation and maintenance require disconnecting multiple components, but this increases maintenance time and complexity
Solution Approach 1:
The pump assembly is segmented into a modular unit with the pump, mounting bracket, and drive mechanism as an integrated assembly that can be installed or removed as a single component from the tank, significantly reducing maintenance time and complexity compared to separate component connections.
