You are here : Mechanical seals in rotating equipment applications and troubleshooting
Mechanical seals on rotating equipment applications in a wide range of mechanical seal seal machine will directly affect the operation, severe major security incidents will occur.
Mechanical seal from the perspective of internal and external conditions affecting the sealing effect of several factors and reasonable measures to be taken.
A mechanical seal principles and requirements
Also known as seal mechanical seal, which is a rotating mechanical seal device, means at least one rotation axis perpendicular to the face in the liquid pressure and stretch compensation mechanism (or magnetic) and the co-ordination role and a secondary seal to maintain Post merger, constitute the relative sliding device to prevent fluid leakage. Its main function will be easy to change the leakage of axial seal leaking seal more difficult. It is widely used in pumps, vessels, compressors and other similar equipment, rotational axis of the seal.
Mechanical seal is usually ring, stationary ring, pressed components and sealing components. Together with the shaft of which ring rotation, rotating ring and stationary ring tightly to form the sealing surface to prevent media leaks. Ring by the pressure of the liquid seal chamber face pressed to the surface of the stationary ring side, and two ring-side surface appropriate to specific pressure and maintain a very thin film of liquid to achieve the purpose of sealing. Pressed components to the pressure, the pump can not operate in the state, but also to maintain end-fitting to ensure no leakage of the sealed medium, and to prevent impurities into the seal face. Sealing components sealing ring and the shaft from the gap, the gap stationary ring and the gland's role, while the vibration of elastic components of the pump, the impact from the buffer. In the actual operation of the mechanical seal and pump is combined with other components to run, the normal operation of the mechanical seal with its own performance, external conditions have a great relationship. But we must first ensure its own part performance, and installation of secondary seals the technical requirements of the mechanical seal to play its due role.
2, the performance of mechanical seal failure and the reasons
2.1 parts of mechanical seal failure during operation of rotating equipment, sealing face would often wear, thermal cracking, deformation, damage, etc., the spring will relax with a long, fracture and corrosion. Also occur secondary ring cracks, distortion and deformation, fracture, etc..
2.2 Mechanical seal vibration, heat Failure
Device rotation, will face rough fit ring movement, movement rings and the gap is too small sealed chamber, the runout caused the collision which led to vibration. Sometimes the seal faces poor corrosion resistance and heat resistance, or inadequate cooling or face particles in the installation folder with impurities, can also lead to mechanical vibrations and heat sealed.
