The role of metal seals for mechanical seals

<p>Everyone is very familiar with <a href="https://www.lepu<a href="https://www.lepuseal.com/" target="_blank">seal</a>.com/" target="_blank">mechanical</a> seals, so there are many types of gaskets for mechanical seals. What is the role of metal toothed gaskets for mechanical seals?</p><p><br></p><p>&nbsp;Metal toothed gasket for mechanical seal:</p><p>&nbsp;&nbsp;124 pump <a href="https://www.lepuseal.com/" rel="noopener noreferrer" target="_blank">mechanical seal </a>metal toothed gasket is easy to leave an indentation on the flange sealing surface after use, so it is generally used in less disassembled parts. The use pressure is 1.96-19.6MPa.</p><p>&nbsp;&nbsp;At the manholes of some large high-pressure vessels that are often disassembled, a soft pad is attached to both sides of the pad, such as asbestos rubber sheet, flexible graphite sheet, aluminum sheet, copper sheet, etc., which not only protects the flange surface, but also has obvious <a href="https://www.lepuseal.com/" rel="noopener noreferrer" target="_blank">mechanical</a> sealing performance. improve. The reason is that this kind of combined toothed pad mainly depends on the soft pad which is easy to produce plastic deformation during pre-compression, and has good contact with the flange surface to form a seal. The soft pad used for the combined toothed pad is very thin and comes into contact with the flange after compression. One side is flat and the other side is tooth shaped. The part pressed by the tooth tip is only 0.1 ~ 0.250mm thick. The gap of plastic flow is very small. With the tooth bite, it is difficult for the flat pad to produce plastic flow, which can maintain a high sealing specific pressure. In addition to increasing the elasticity of the combination pad, the toothed pad also strengthens the soft pad, so that materials with lower strength such as asbestos rubber sheet can withstand high pressure.</p>
