Application of mechanical seal elastic component in rubber seal.

The suspension system is subjected to a vertical load and a component which is subjected to the impact caused by the mitigation and suppression of the road surface.Its function is to bear and transmit the vertical load, ease and restrain the impact caused by uneven pavement.Elastic components are sort into metal and nonmetal two parts by difference materials.

Spring rate is elastic body restore elasticity, is refers to the seal material in love after loading, unloading to zero deformation recovery ability, and its value for unloading the decrease of the thickness of the total thickness of the team to pre load the decrease of the thickness of the total thickness by 100%. As metal ,its high rebound rate shows that it has good contact with the metal materials, as long as there is a smaller clamping force, it can achieve a good sealing effect.

The elastic element of the mechanical seal is composed of a spring and a corrugated pipe.The spring and the corrugated pipe is a spring-loaded element, its biggest effect is to ensure the mechanical equipment of dynamic seal ring and a stationary seal ring combination, pre pressing and face wear or flow to play the role of automatic compensation.

The requirement for elastic sealing material:Corrosion resistance in medium, never lose or increase original elasticity for a long working time.And it can keep the pressure of tight after the sealing surface has been wear,that its increasing rate is less than original spring force 10%~25%. Above is all the applications about an elastic member of rubber seals of the mechanical seal.

     Compression deformation is one of the most important parameters when the seal is sealed.Compression permanent deformation is a measure of the size of the seal after compression.Under the condition of constant pressure, the compression deformation is not so important.However, the pressure applied to load drop, then applied occasions, it is very important to the compression parameters.Permanent deformation of the poor performance of the seal, the gap will not be sealed effect.In addition, the use of temperature in the selection of the seal is not suitable for compression deformation will occur.
