씰링 링의 표면 지형: Ra 0.04–0.05 μm의 실제 의미

In mechanical seals, the surface topography of sealing rings directly affects leakage control, lubrication retention, and wear resistance. An Ra value between 0.04–0.05 μm is often specified for high-performance applications, but many decision-makers may wonder what this number truly represents and why it matters. This article explains Ra 0.04–0.05 μm in simple terms, its impact […]

카바이드 씰 링에서 거울 수준 마감 달성: 공정 창 및 함정

Carbide seal rings are critical components in pumps, compressors, and valves for industries such as oil & gas, chemical processing, power generation, and marine systems. Achieving a mirror-level finish on these rings ensures leakage control, low friction, and long equipment life. However, achieving a perfect mirror finish is not easy. It requires strict process windows, […]

초미세 마감과 미세 포켓 마감: 초경 표면의 윤활 유지

In mechanical seals, the surface finish of carbide faces affects not only leakage control but also lubrication retention. Two popular finishing approaches—ultra-smooth finishes and micro-pocketed finishes—offer different advantages depending on the operating conditions. For decision-makers in industries like oil & gas, chemical processing, marine systems, and power generation, understanding these finishes helps improve seal performance, […]

카바이드 페이스 래핑을 위한 컨디셔닝 링, 플레이트 선택 및 슬러리 제어

In mechanical seal manufacturing and maintenance, carbide face lapping is a crucial finishing process. Proper lapping ensures surface flatness, low roughness (Ra), and tight sealing performance. Three key factors—conditioning rings, lapping plate selection, and slurry control—determine the quality and repeatability of the finish. This guide explains how these elements affect carbide face lapping and provides […]

초경 씰 표면의 목표 Ra 및 평탄도: 래핑 및 연마 모범 사례

Carbide seal faces are critical for pumps, compressors, and valves in industries like oil & gas, power generation, chemical processing, and water treatment. The surface roughness (Ra) and flatness of these seal faces directly affect leakage control, wear resistance, and equipment reliability. Lapping and polishing are two essential finishing processes that define the final Ra […]
