Mechanical seal selection methods and principals

<p>The<a href="https://www.lepuseal.com/products-1" rel="noopener noreferrer" target="_blank"> <strong><a href="https://www.lepuseal.com/products-1" target="_blank">mechanical seal</a></strong></a> is one of the more complex mechanical structure of the base element, a variety of mechanical seal pumps, reaction synthesis reactor, the key components of the compressor turbine, submersible motors and other devices. Sealing performance and service life depends on many factors, such as selection, so then introduced on the method and principles of its selection.</p><p><br></p><p>First, the selection method</p><p>Mechanical seal according to the working conditions and the nature of the medium is different, there is high temperature, low temperature mechanical seals, high pressure, corrosion-resistant mechanical seals, mechanical seals and resistance to particulate media adaptation mechanical seal easily vaporized light hydrocarbons and other media, according to the different select a different structure type of use and mechanical seal materials.</p><p>Selection of the main parameters are: seal chamber pressure (MPA), a fluid temperature (℃), the operating speed (M / S), fluid properties, and mechanical seal effectively seals the installation space.</p><p><br></p><p>The basic principle of selection is as follows:</p><p>1. The seal chamber pressure, the sealing structure is determined using the balanced or balanced, single face or double face and the like.</p><p>&nbsp;2. The operating speed is determined using a rotary or static, fluid dynamic pressure type non-contact type.</p><p>3. The temperature and fluid properties, determines the friction pair and the auxiliary sealing member, and the correct choice of lubrication, washing, thermal insulation, mechanical seal cooling circulation protection system.</p><p>4. The mounting space effectively sealed is determined using multiple springs or a single spring or wave spring, built-in or externally mounted.</p><p>In summary, according to the method described above for selection of a mechanical seal, using better equipment and guarantee the performance of the play related, extend, reduce damage.</p><p><br></p><p><strong>Lepu seal</strong>, a professional <a href="https://www.lepuseal.com/" rel="noopener noreferrer" target="_blank">mechanical seal manufacturer</a> &amp; mechanical seal supplier with years of experience.
