There are two types of mechanical seals, the dynamic ring and the static ring, but many users cannot distinguish the accessories well during use, so they cannot meet the use requirements during use. For this, the following is the dynamic ring and the static ring. Introduce the difference.

1. Different rotation methods:

The static ring rotates along the axis at high temperature and high speed;

The moving ring moves axially under the thrust of the spring.

2. Different contact surfaces:

The contact surface of the static ring is relatively narrow, and it is more convenient to operate;

The contact surface of the moving ring is relatively wide, and the operation is not very easy;

3. Whether it is on the gland:

The static ring is mounted on the gland and connected with the spring;

The moving ring is installed on the shaft, the static ring does not rotate, and the moving ring rotates with the shaft;

Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the medium in the equipment leaks out through this gap. If the pressure inside the equipment is lower than the atmospheric pressure, the air leaks into the equipment, so there must be a Shaft sealing device to prevent leakage.

The above is the introduction of the difference between the dynamic ring and the static ring of the mechanical seal. According to the introduction, it is convenient for users to make a better distinction, so as to provide convenience and improve efficiency for later use.
