Solution Overview
Problem
Conventional mechanical seals face challenges in preventing deposit formation on sealing faces, especially when using fluids that contain deposit formation-causing substances, which can degrade their performance over time.
Innovation Solution
A slide component design featuring a pair of sliding parts with a fluid circulation groove and interference grooves that create pressure variations, preventing deposit formation by ensuring continuous fluid movement and maintaining sealing function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fluid circulation groove is provided to promote fluid circulation and prevent wear, then lubrication performance is improved, but deposit formation on the sealing face worsens due to stagnant fluid areas
Solution Approach 1:
The invention introduces interference grooves that convert static fluid circulation into dynamic flow patterns. The interference grooves create alternating high and low pressure zones that generate fluid circulation variations, preventing fluid stagnation and deposit formation while maintaining the sealing function.
Solution Approach 2:
The interference grooves produce periodic pressure variations in the fluid circulation groove. This periodic action creates alternating flow patterns that continuously refresh the fluid in contact with the sealing face, preventing deposit formation by deposit formation-causing substances while maintaining lubrication.
2Force
If grooves are introduced to form fluid layers for preventing wear, then friction reduction is improved, but fluid leakage increases due to disrupted sealing faces
Solution Approach 1:
The invention applies different groove structures to different functional areas: the fluid circulation groove handles fluid supply and circulation, while the interference grooves localized in specific positions create pressure variations. This local differentiation allows friction reduction through fluid layers while maintaining sealing integrity through controlled pressure zones.
Solution Approach 2:
The interference grooves change the pressure parameter of the fluid dynamically, creating alternating high and low pressure zones. This parameter change enables the fluid to maintain contact with the sealing face for friction reduction while the pressure variations prevent fluid leakage by controlling fluid flow paths.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents deposit formation and maintains the sealing function for a long period by creating alternating pressure differences between the inlet and outlet portions of the fluid circulation groove, even when the fluid contains deposit formation-causing substances.
Implementation Method 1

AI summary
Provided is a slide component that can prevent deposit formation on a sealing face as well as promoting circulation of a fluid on sealing faces while fulfilling both conflicting conditions of sealing and lubrication, to maintain the sealing function of the sealing faces for a long period of time. The slide component includes a pair of slide parts that relatively slide on each other, one of the slide parts being provided in a sealing face with fluid circulation grooves 10 that communicate with a high-pressure fluid side via an inlet portion and an outlet portion and are separated from a low-pressure fluid side by a land portion, the other of the slide parts being provided in a sealing face with interference grooves 15 that communicate with the high-pressure fluid side and produce pressure variations in a fluid in the fluid circulation grooves 10.
