Mechanical seals for ultra high pressure. Since mechanical and thermal deformations are dangerous for the performance and operational reliability of the mechanical seal even when operating in the range of medium and high pressures, at their maximum possible values, the probability of failure increases significantly. The weakest parts are carbon-ceramic sealing rings with reduced strength. In this case, it is preferable to use metallized coals, since they withstand high stresses, have an increased modulus of elasticity and a more favorable coefficient of thermal conductivity. This allows you to limit the mechanical and thermal deformation narrow limits. With large ring sizes,...

Reliability of mechanical seals. Mechanical seals work in a variety of conditions, so along with leaks, durability and power losses, their operational reliability and reliability are crucial. Unlike previously used glands, mechanical seals can fail instantly, for example, due to separation of sealing surfaces, destruction, cracking of friction surfaces from thermal stresses, with unacceptably high temperatures and their differences. Due to the increased danger of poisonous explosive, flammable and radioactive media, as well as large costs required for their possible repairs, often causing downtime of entire installations, it is necessary to carefully check the inaccuracy and reliability of the selected...
