Hydraulic Piston Pump Mobility With Pulsation-Reducing Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drywall installation systems face inefficiencies in transferring abrasive materials due to rigidly mounted pumps that require tilting and tilting over, leading to seal deterioration, high maintenance costs, and pulsation issues, especially when dealing with high-capacity reservoirs.
Innovation Solution
A remotely tethered hydraulically powered piston pump that allows physical manipulation between reservoirs, featuring a compressible pressure sleeve to reduce pulsation and a durable wearing sleeve for extended use, with a metering device for controlled flow, enabling independent operation and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pump is rigidly mounted to a frame structure, then the pump structure is stable and secure, but the pump cannot be physically manipulated or lifted independently
Solution Approach 1:
The pump is divided into two independent parts: a portable pump body that can be manually manipulated and a separate frame structure that remains stationary. The pump body includes a pump motor, piston, and discharge mechanism, while the frame provides structural support and houses the material reservoir. This segmentation allows the pump to be easily moved between reservoirs without moving the entire frame structure.
2Ease of operation
If the pump tilts and tilts over during manipulation, then the pump can be moved between reservoirs, but the seals deteriorate and maintenance costs increase
Solution Approach 1:
The pump body is designed with a low center of gravity and a stable base that prevents tilting during manipulation. The pump motor and piston assembly are securely mounted within the pump body housing, maintaining proper alignment and preventing excessive movement that would damage seals. This dynamic stability allows the pump to be easily moved while protecting the seals from deterioration.
3Productivity
If the pump operates with high-capacity reservoirs, then the material transfer capacity increases, but pulsation issues arise
Solution Approach 1:
The pump employs a double-acting piston mechanism that delivers continuous material flow without pulsation. During the upward stroke, the piston draws material into the pump chamber through an inlet valve. During the downward stroke, the piston forces material out through the discharge port. This continuous reciprocating action ensures steady material transfer from high-capacity reservoirs without the pulsation problems associated with single-acting pumps.
4Device complexity
If the pump motor is non-replaceable, then the pump structure is simpler, but maintenance costs increase
Solution Approach 1:
The pump motor is designed as a separate, replaceable component that can be easily removed and replaced without disassembling the entire pump body. The pump motor housing includes mounting features that allow quick attachment and detachment. This modular design simplifies maintenance by allowing technicians to replace worn motors without replacing the entire pump assembly, reducing maintenance costs while maintaining structural simplicity.

AI summary
A piston-driven pump apparatus configured to transfer liquid-based abrasive materials via a pressurized hydraulic medium which is capable of physical manipulation between remote material reservoirs. The apparatus exhibits a remotely tethered double-acting pump having independence from a fluidic supply source. The pump is configured to be removed from a first material reservoir and placed in communication with a second material reservoir by physical manipulation. The apparatus has a cylindrical sleeve assembly which has a wearing sleeve which may be removed and/or rotated to increase the operational time of the apparatus before an end-of-life replacement of the sleeve is required. The apparatus diminishes a pulsation effect of conventional double-acting piston pumps via a compressible pressure sleeve which is capable of deformation within a pump housing. A metering device is present to control the external flow of abrasive material, providing back pressure against an internal compressible sleeve.
