On the mechanical seals on rotating equipment applications and troubleshooting

Mechanical seal rotating equipment applications in a very wide range of mechanical seals sealing effect will directly affect the operation of the machine, will also appear serious major security incidents.
From the perspective of the mechanical seal internal and external conditions of the analysis of several factors and reasonable measures should be taken to affect the sealing effect.
Principles and requirements of a mechanical seal
Mechanical seals also known seal, indicative seal which is a mechanical means for rotating the shaft sealing means comprises at least one end surface perpendicular to the axis of rotation of the liquid is maintained at a pressure compensation mechanism and the spring force (or magnetic), and the auxiliary sealing action with Post consolidation relative sliding of the device to prevent fluid leakage. Its main function will be easy to change the axial seal leaks difficult end face seal leakage. It is widely used rotary shaft seal pumps, vessels, compressors and other similar devices.
Mechanical seal rings usually by the dynamic and static ring, composed of pressed components and sealing elements. One ring rotates with the shaft, ring and stationary ring sealing surface composed of tightly bonded to prevent media leaks. Ring seal chamber by the pressure of the liquid face pressed to the end face of the stationary ring and generates the appropriate specific pressure and maintaining an extremely thin liquid film on the end face two rings to achieve the purpose of sealing. Clamping element generates pressure, the pump is not running in the state,wire seals but also to keep the end face fit, to ensure sealing medium does not leak and prevent contaminants from entering the seal faces. From the gap sealing element and the shaft seal ring, the role of the stationary ring and gland clearance, while the elastic element to pump vibration, shock dampening effect. In actual operation of mechanical seals and other components are combined together to pump up the operation, the normal operation of the mechanical seal with its own performance, the external conditions have a great relationship. But we must first ensure their own performance parts, and technical requirements of the secondary seal installation, mechanical seals play its due role.
