Modular Pump System Detachable Unit Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pump systems require complex and cumbersome procedures for replacing and maintaining hydraulic pump bodies, as they are often connected to a supporting member like a vehicle frame, making operations less operable and risking accidental drop of parts.
Innovation Solution
A pump system design where the pump unit, including hydraulic pump bodies and a PTO unit, is detachably connected to a base unit, allowing for independent detachment without disconnecting the transmission mechanisms from the driving source, enabling efficient replacement and maintenance of hydraulic pump bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump case is connected to the supporting member or port block is connected to the pump case, then the pump unit can be securely mounted and transmit power effectively, but the hydraulic pump bodies become difficult to access for replacement and maintenance
Solution Approach 1:
The pump system is divided into distinct modular units: a base unit containing the PTO unit and input shaft, and a pump unit containing the hydraulic pump bodies and pump case. These units are detachably connected, allowing the pump unit to be separated from the base unit for maintenance while keeping the transmission mechanisms connected to the driving source.
Solution Approach 2:
The pump unit is designed to be extractable from the base unit through a detachable connection. This allows the hydraulic pump bodies to be accessed and maintained by simply detaching the pump unit from the base unit, without needing to disconnect the transmission mechanisms from the driving source or PTO unit.
2Ease of repair
If the pump unit is entirely separated from the supporting member or port block is separated from the pump case for maintenance, then the hydraulic pump bodies can be accessed, but the transmission mechanisms must be disconnected from the driving source or PTO unit
Solution Approach 1:
The pump system is segmented into a base unit and a pump unit that are detachably connected. This segmentation allows maintenance personnel to access the hydraulic pump bodies by simply detaching the pump unit from the base unit, without needing to disconnect the transmission mechanisms from the driving source or PTO unit, thereby reducing disassembly complexity.
Solution Approach 2:
The pump unit is designed as an extractable module from the base unit. This extraction capability enables maintenance of the hydraulic pump bodies through a simple detachment operation, avoiding the complex disassembly required to disconnect transmission mechanisms from the driving source or PTO unit.
3Ease of repair
If the port block is separated from the pump case with the pump case connected to the supporting member, then the hydraulic pump bodies can be accessed, but the parts may drop out against a user's will
Solution Approach 1:
The pump unit is segmented as a complete modular assembly that includes the pump case, port block, and hydraulic pump bodies. This segmentation ensures that when the pump unit is detached from the base unit for maintenance, all internal components remain contained within the pump unit, preventing parts from dropping out during the maintenance process.
Solution Approach 2:
The pump unit is extracted as a complete module from the base unit. This modular extraction design maintains the integrity of the pump unit's internal structure, ensuring that the hydraulic pump bodies and other components remain securely contained within the pump unit during maintenance operations, eliminating the risk of parts falling.
