<p><a href="https://www.lepuseal.com/products-1" rel="noopener noreferrer" target="_blank"><strong>Mechanical seals</strong></a> are one of the basic components of precision machines, with a relatively complex structure. They are joint components of various pumps, reactive and synthetic sealing devices, turbo compressors, and submersible electric ideas. The sealing performance and service life of the seals depend on the selection, accuracy and correctness of the installation and use of the machine equipment. The sealing power associated with centrifugal force will also increase.</p><p><br></p><p>Selection skills:</p><p>Due to the difference between the working conditions of the <a href="https://www.lepuseal.com/products-1" target="_blank">mechanical seal</a> and the characteristics of the medium, there are mechanical seals with high temperature resistance, low temperature resistance, high pressure resistance, corrosion resistance, and particle resistance, as well as mechanical seals suitable for easily evaporating light hydrocarbon media. Therefore, it should be based on the application. Choose different structural types and materials for mechanical seals.</p><p>The important parameters selected are: sealed chamber pressure (MPA), liquid temperature (℃), working speed (M/S), liquid and liquid characteristics, and installation and sealing space, etc.</p><p><br></p><p>The selection principle of mechanical seals is:</p><p>According to the pressure of the sealed cavity, the sealing structure can be balanced or unbalanced, such as single end face or double end face.</p><p>According to the speed of the homework, rotation or consolidation, hydraulic pressure or non-contact type can be used.</p><p>According to the temperature and fluid characteristics, choose the alternate and auxiliary sealing materials, as well as the circulation protection system of the mechanical seal such as lubrication, flushing, heat preservation, cooling, etc.</p><p>According to the size of the mechanical seal installation space, it adopts multiple springs, single springs or wave springs, inside or outside. Impurities are deposited on the veneer of the mechanical seal.</p><p>The technical requirements for installation and use are relatively high, especially sensitive to shaft runout and shaft jump. When machine maintenance is carried out, the bearings and the motor should be adjusted harshly.</p>
