Analysis by a beginner: uneven installation and medium corrosion have an impact
The main reasons for the damage of the diaphragm in a diaphragm gauge include: operation under overpressure, corrosive media, vibration-induced wear, temperature changes, and improper installation. .
There are generally several reasons for the damage to such diaphragm boxes: one is damage caused by collisions during installation, another is the presence of foreign objects in the medium (such as stray bolts), and yet another is freezing of the medium or water due to low temperatures. I’ve also encountered a situation where negative pressure was applied during the production process, which caused damage
The plug-in pressure transmitters used in the past suffered from membrane damage due to the high-speed friction caused by particles in the medium; eventually, wear-resistant, thicker membranes were adopted
I believe that the depth of insertion has a significant impact on the liquid scouring of the diaphragm, and it is necessary to design it properly.
