Cracking the bimetallic thermometer sheath factors have?

Bimetallic thermometer sheath is commonly used to form a complete set of industrial equipment and bimetallic thermometer, it mainly has two aspects, on the one hand is convenient disassembly, on the other hand is used in a specific environment, can help the bimetallic thermometer cushion some of the pressure. But in actual use process, occasionally, the phenomenon of the bimetallic thermometer sheath rupture. According to our many years of experience in production of the bimetallic thermometer, summarizes the leads to the cause of the bimetallic thermometer sheath is as follows: 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; 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.
