The whole process of mechanical seal installation
Mechanical seal, also known as end seal, is a device used to solve the seal between the rotating shaft and the body, and is often used in rotary fluid machinery such as pumps. Therefore, the mechanical seal is a general shaft seal device. Mechanical seals are divided into contact and non-contact two, most of the current use of contact mechanical seal, and non-contact mechanical seal is developing, and has attracted people’s attention. Mechanical seal is a non-functional part of the machine, but it plays a great role in reducing leakage and stabilizing production.

Working principle of mechanical seal
The working principle of the mechanical seal is to use two mutually attached, flat and perpendicular to the axis of rotation of the sealing surface, and relative rotation of the sealing device. It relies on the pressure of elastic elements (such as springs or bellows) and the sealing medium to generate appropriate pressing force on the contact ends of the moving ring that rotates with the shaft and the static ring that does not rotate with the shaft, so that the two contact end faces are closely Fit, and a very thin liquid film is maintained between the end faces, so as to achieve the purpose of sealing.
