With the different seals used by various enterprises, all kinds of seals are widely used. The two most commonly used ones are mechanical seals and hydraulic seals. Many users may not be able to tell them apart and often think they are the same product. Therefore, in order to better help everyone distinguish between purchases, the differences will be introduced next.

1. Definition

Mechanical seal belongs to precision and precision. It is one of the basic mechanical components with complex structure, and is the core component of various pumps, reaction generators, turbo compressors, submersible motors and other equipment. Its sealing performance and service life depend on many factors, such as selection, precision of the machine, correct installation and use, etc.

There are pressure requirements for hydraulic seals, and the joint surface is required to have a certain degree of smoothness. The seals are mostly made of rubber, and the sealing effect is achieved according to the partial deformation of the seals.

2. Classification

Mechanical seal model: cartridge seal series, light mechanical seal series, heavy seal series, etc.

Types of hydraulic seals: lip seals, V-shaped seal rings, U-shaped seal rings, Y-shaped seal rings, YX commonly used combined seal rings and hydraulic cylinders are mainly bud seal rings, rings and step seals.

The above are the different introductions of the two kinds of equipment, mechanical seal and hydraulic seal. According to the introduction, it can facilitate the purchase and use of later equipment, avoid selection errors, increase enterprise costs, and affect use.
