Tips: Diaphragm coupling advantages
The diaphragm coupling has a simple structure and high reliability. It is suitable for high-speed, high-power, high-temperature and corrosive environments. It has great axial and angular compensation, good anti-misalignment, and has vibration absorption and vibration isolation functions. The coupling has no noise, zero clearance, constant speed, no need for lubrication. The additional load acting on the connected equipment is small, and the diaphragm coupling is easy to install, use and maintain.
