The bimetallic thermometer sheath rupture factors have?

Bimetallic thermometer sheath is mainly used in industrial equipment and the bimetallic thermometer, with it, we can easily remove the bimetallic thermometer. But in the process of using sometimes appear fracture, bimetallic thermometer sheath so bimetallic thermometer sheath rupture factors what? Causes of the bimetallic thermometer sheath rupture may have many, we according to the actual situation of daily, summarizes the four could lead to failure of bimetallic thermometer sheath. 1. Bimetallic thermometer sheath is impacted by the high velocity, heavy load, the stress over speed; 2. Bimetallic thermometer sheath itself defects, lead to stress concentration, easy to cause fracture; 3. Using the environment vibration, bimetallic thermometer sheath fatigue damage; 4. When the fluid flows through the bimetallic thermometer sheath, bimetallic thermometer sheath induced vibration, namely the bimetallic thermometer sheath vortex shedding frequencies and fluid resonance frequency. The resonance phenomenon causes bimetallic thermometer sheath damage speed, until the break.
