The wettability of sealing materials and its effect on sealing performance: Part I
Sealing Technology, 2016Wetting influences the sealing mechanisms of rotary shaft lip seals and rod seals. This article, published in two parts, shows how to determine the surface free energy of sealing materials, especially elastomers. Wetting parameters and their influence on sealing operation are explained, and a hypothesis is proposed to connect wetting phenomena with ...

Sealing and Chromatographic Performance of Microgroove Columns
Analytical ChemistryIn a recent paper, we introduced the concept of structured microgroove columns as a potential solution to obtain perfectly ordered particle beds for nano- and micro-LC. In this concept, spherical particles are either individually positioned (single layer column) or stacked (multilayer column) in a series of interconnected micromachined pockets.

Sealing performance prediction software
Sealing Technology, 1997Abstract Elastomer seals are widely used throughout industry and seal failure can be very expensive, in both financial and safety terms. One failure mode causing major concern is progressive degradation. It is generally of a long term nature and its extent and consequences in service can be particularly difficult to predict.

Influence of Sludge on Seal Performance
SAE Technical Paper Series, 1998<div class="htmlview paragraph">There is a case of leakage caused by improper lip contact due to the build-up of sludge on the lip area. Sludge, which is mainly carbide, is generated typically from aged oil under high temperature (150°C or more) conditions. However, it can also be generated in driving systems such as transfers.

Monitoring the performance of rubber seals
Metallurgist, 1986Two types of rubber seals are used to join the pipes which deliver oxygen to the bottom of a converer: a circular ring, the specifications of which are given by GOST 9833-73; cuffs, the specifications here given by GOST 14896-74. The performance of the rings is determined by the resistance of the rubber to oxygen, the tightness of the seal, and the ...

Seal Leakage Performance Characterization
A S L E Transactions, 1977The use of the “flow resistance” concept in the sealing context is discussed. A number of model seal configurations are dealt with in detail, leading to the expressions for flow resistance. It is pointed out that flow resistance for seals parallels the load capacity of bearings as a quantitative measure of performance and it is concluded that, although

Performance Testing Of Mechanical Seals
1992To demonstrate the performance capability of a particular mechanical seal design in an objective way demands some means of referencing an adequately arduous test condition appropriate to the seal in question. The minimum point on the friction coefficient versus duty parameter curve is a tribologically meaningful reference point which could be used to ...
