What is the difference between multi-spring mechanical seals and single-spring mechanical seals?
Thread Content
The axial dimensions of multi-spring mechanical seals are relatively small, and the elastic force is fairly uniform; they are suitable for high-speed mechanical seals when installed in a stationary position. The single-spring mechanical seal has uneven spring force and a relatively large axial dimension.
Single springs are generally used in corrosive media
Use a single spring when the length-to-diameter ratio is high; pay attention to the rotation direction
You can take a look at the section on \"Mechanical Seals\" in Volume 3, Fifth Edition of the Mechanical Design Handbook!
