Note: Thermal expansion and contraction cause pressure difference btween internal and external of the lamp body, mist in interior lamp body and the waterproof problem and etc.
We suggest the front and rear end of the laser should not be completely fixed at the same time,avoid the deformation of the cavity due to the stress caused by the thermal expansion of the material.
Tungsten carbide is widely used as seal faces with resistant-wearing, high fracture strength, high thermal conductivity,small heat expansion co-efficient.
Any overpressure which may be generated by the thermal expansion of the fluid trapped in the body cavity with the ball in fully closed position, will be automatically discharged in the line on the lower pressure side.
It controls thermal expansion mismatch between the substrate and the functional coating, and is applied as an intermediate coating between the metallic bond coat and the ceramic top coat.
Adopt horizontal type three pass structure and large furnace, to ensure the sufficient combustion,and the boiler could absorb the thermal expansion effectively.
These materials have some advantages: the arc ablation resistance, good thermal conductivity,and small thermal expansion, not soften in high temperature, softening, high strength, high density, high hardness etc.
Metal-Polymer Bearings take advantage of the out-standing dry bearing properties of PTFE and combines them with strength, stability and good wear resistance,excellent heat conductivity and low thermal expansion.
Utilizes Compressed Mechanical seal technology and Air pressure balance threadplug to solve the waterproof/protection problem caused by thermal expansion and contraction.
