Conventional and Interactive Skill Tests with evaluation, 7. Where the media contains assorted particles, then harder faces would be used either carbon against silicon carbide, or perhaps silicon carbide against-silicon carbide. Seals are typically accompanies oil bolster line and oil search line for better execution. The Mechanical Seal Training Course covers a large range of Seal types like Pusher Seals, Non-Pusher, Cartridge, Split, Double, Tandem, Dry Gas Seals, Spring, Bellow Seals, etc. Rings of ceramic, carbide, carbon or composites of these materials are lapped flat in the range of less than 1 micron on an axial end face. To keep mechanical seal systems functioning as long as possible, we recommend using standardized seal piping plans. Popular mechanical seal mating rings come in ceramic (white) and sintered nickel-iron (gray). Selecting the correct faces, correct spring length, and with the right elastomeric secondary seal will prevent early seal failure. General overview of mechanical seals. The rubber parts of the mechanical seal mustn’t be attacked by the media used. This article covers best practices in seal piping installation, and outlines API standards for mechanical seal … The Mechanical Seal Training Course has been developed to assist in Maintenance and Operation. fundamentals training, and have Yes Yen build more updated modules to The MECHANICAL SEALS TRAINING course provides a (Windows OS). There are two modes of operation to choose from: Barrier Fluid : Fluid pressure is 15-30 Psig/1-2 Bar higher than the pumped fluid pressure The type and length of the spring is designed to provide the correct pressure. The course, designed with extensive Graphics and Animation, gives a virtual Practical exposure on Mechanical Seals. These lapped faces run against each other, one rotating with the shaft and the other stationary with the equipment housing. It is very difficult for leakage to occur (beyond a … Multiple user option- For simultaneous access in an organization LMS. Popular mechanical seal … The manufacturer listings are alphabetical, refer to pages 7 - 13. Purpose of Flush: Introduce fluid into seal chamber to improve the lubrication. The mechanical seal Mechanical seals have the purpose of preventing leakage of a fluid (liquid or gaseous) through the clearance between a shaft and the fluid container. Mechanical Seal – Mechanical engineering is a constantly evolving niche. Dry gas seals are non-contacting, dry-running mechanical face seals that consist of a mating (rotating) ring and a primary (stationary) ring. Gland packing was traditionally used for this purpose but in higher specif… Choosing the correct elastomer will help prolong the life of the mechanical seal. Mohammed Zuber. Every seal design is distinctive in some respects and must be treated independently. and application specific seals not listed are stocked and are available by request. Online course access for 60 days. and provides a detailed Mechanical Seal Classification. Without lubrication between the two seal faces, the equipment would quickly overheat, causing damage to the seal and possibly to the shaft as well. A video about mechanical seals from the Garlock family of companies. The CBT provides a detailed knowledge on Seal Installation, Assembly and Dismantling. Working with a competent seal manufacturer avoids mistakes and adds value (Ref. This way (using Yes Yen CBTs) we can move forward with upgrading the Two mating faces contact each other forming a seal at the mating surface. Mechanical seals are used to seal the rotating equipments. Used when the process fluid... Used when the process fluid is highly dangerous and a failure of one primary seal could put employees or the environment… Copyright © 2020, Yes Yen GraphiTech, All rights reserved. To identify the working length, measure your mechanical seal end to end as it is pictured above, this is your seals "total length". Mechanical seals generate frictional heat as the primary ring and mating ring rub together. mechanical seal and is defined as In practice k values are selected between 0.65 and 1.2. The components of the recipe enable the proper tribology—too much or too little film transfer would result in shortened life or performance of the mechanical seal. Mechanical seals are manufactured with different face materials depending on the application involved. A mechanical seal’s mating pair is the heart of the system and the two components are designed to work together. As you work with your mechanical seals manufacturer, remember that a mechanical seal recommendation is not complete without a seal support plan. and provides a detailed … where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft… Our Mechanical Seals are used in a wide range of pumps and rotating equipment worldwide … The Mechanical Seal Training Program has a dedicated module to assist in Seal Troubleshooting with a very useful graphical interface. Low pressure radial lip seals (less than 3 psi.) 1) Rotating and fixed face: The rotating and the fixed faces are the two vital parts of the mechanical seals.The rotating face is connected to the rotating shaft while the fixed face is connected to the pump housing. In a regular mechanical seal, there are three basic mechanisms working to maintain the seal: There are slight variations to this but this is the general principle to which all mechanical seals work. (Here's an example where a paper mill replaced packing with a mechanical seal to stop leakage.) Mechanical Face Seal Replacement How To Use This Catalogue ♦ Locate the manufacturer of the equipment. O-Type Mechanical Seal Description: Nitrile rubber is one of the most commonly used rubbers and has a very good cost performance. ♦ Identify the correct replacement seal. Which is the best and most effective sealing technology for your pump or agitator application? USING MECHANICAL SEALS. Seals are used to keep liquids and gases from entering certain areas or mixing with one another. The mechanical seals help sealing the rotating part of the shaft against the stationary part of the pump housing. Here are 6 of the most common reasons mechanical seals can fail. EKATO is one of the pioneers in the use of mechanical seals in agitators and continue to produce them today. *The above image is a compilation of a few 'snapshots' from the Training Course on Mechanical Seals, which primarily focuses on Multimedia inputs like Graphics, Animation and Interactivity! We doesn't provide mechanical seal working products or service, please contact them directly and verify their companies info carefully. Mechanical Seals vs. mechanical seal working. A further distinctive feature is the type of seal lubricant. Long ago, companies didn’t want to switch to mechanical seals because of the complicated installation and need to completely disassemble the equipment. The two seal faces are pressed together by … For applications where the media might be sticky, e.g. To identify the working length, measure your mechanical seal end to end as it is pictured above, this is your seals "total length". These are used to seal the process side of the equipments like pumps, agitators, etc… there are many varieties of mechanical … The "working length " of the seal is critical to your seal application. Normally less than 1 bar (g). This is vital for understanding how does a mechanical seal work. The Mechanical Seal Graphic has detailed Animated Cut-Sections that gives a virtual knowledge of the internals, which could otherwise be very difficult to understand. Every year, there are new developments and advancements that make the processes … The primary focus on Mechanical Seal Animation and Graphic helps in very clearly understanding Mechanical Seal Working Principle / Operating Principle. The biggest benefit of using mechanical seals is the drastic reduction in leakage. All mechanical seals function basically the same way. Work to support the piping plan. Mechanical Seals: Working Length The "working length" of the seal is critical to your seal application. and application specific seals not listed are stocked and are available by request. 2) Secondary sealants: Between the two faces of the mechanical seal the secondary seals, known as shaft and insert mountings, like O-rings, wedges and V-rings are inserted.
