Electromagnetic Pump Strainer Assembly Using Segmented Side Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small-sized electromagnetic pumps face difficulties in assembling strainers due to their compact size, which complicates the integration with other components.
Innovation Solution
The design incorporates a disk-shaped strainer member with extending side portions that fit over a tubular suction check valve, utilizing clips for secure alignment and a cover member to press the strainer surface uniformly, allowing for easier assembly and preventing slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electromagnetic pump is made small in size, then the compactness is improved, but the ease of assembly deteriorates due to difficulty in assembling the strainer
Solution Approach 1:
The strainer is divided into a disk-shaped portion and a side portion that extends from the outer peripheral edge. This segmentation allows the strainer to be assembled in a specific sequence (piston, urging member, suction check valve, and strainer member sequentially inserted) and provides alignment features that facilitate assembly even in small-sized pumps.
Solution Approach 2:
The side portion of the strainer extends radially outward from the disk-shaped portion, creating a multi-dimensional structure. This extension provides engagement surfaces and alignment features in the radial direction, enabling secure assembly of small components through dimensional variation rather than relying solely on component size.
2Volume of moving object
If the strainer size is reduced to match small pump size, then the compactness is improved, but the alignment precision deteriorates
Solution Approach 1:
The side portion extending radially from the disk-shaped strainer provides alignment features in the radial dimension. This extension creates engagement surfaces that ensure precise alignment between the strainer and the suction check valve, compensating for the reduced size of the strainer itself.
Solution Approach 2:
The sequential insertion design (piston, urging member, suction check valve, and strainer member) allows each component to be positioned and aligned before the next component is added. The side portion of the strainer is designed to align with specific features on the suction check valve during this sequential assembly process, ensuring precise alignment is achieved through the assembly sequence rather than requiring high-precision manufacturing of tiny components.

AI summary
An electromagnetic pump configured with an electromagnetic portion that generates an electromagnetic force for pressing the piston, and an urging member that urges the piston in a direction opposite to the electromagnetic force. A strainer member including a disk-shaped portion which has a disk shape and in which a strainer surface is formed, and a side portion that extends from an outer peripheral edge of the disk-shaped portion. A suction check valve being capable of sucking the working fluid via the strainer surface. The piston, the urging member, the suction check valve, and the strainer member are sequentially inserted into the cylinder from a side opposite to the electromagnetic portion, and the cover member is attached so as to press the strainer surface.
