What seal should be used for the rotary seal ring?

The rotary seal ring shall be a rotary shaft lip type seal ring of fluorine adhesive. If an O-ring is used, it is recommended to add an elastic pressure to the rotating sealing ring to maintain the contact of the sealing surface, but the effect is not very ideal. Try to use a skeleton to seal. It is recommended to use a mechanical seal. Generally, a bearing is required for rotation. The bearing should be pressed by the bearing cover, and the sealing ring should be installed on the bearing gland. According to the different sealing materials and sealing degree, there are various sealing methods: very common rubber seals, packing seals, mechanical seals and labyrinth seals.

Polytetrafluoroethylene is generally called "non-stick coating", which has excellent properties such as low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, no hydrolysis, and no hardening. It is often used as a sealing gasket and various media Lubricating materials.

The rotating seal ring needs to be fast and accurate, and the PTFE sealing lip is more suitable.

Extended Information:

A reliable solution for sealing a rotating body with a diameter of one meter is to use a labyrinth oil seal, that is, a non-contact mechanical seal.

Features of rotary seal ring:

1. Good dimensional stability;

2. High pressure resistance, wear resistance and high temperature resistance;

3. Resistance to most media, strong chemical resistance;

4. The installation space is small, the groove is simple, and there is a lubrication cavity;

5. A piston rod or piston is required.

high speed rotating seal ring used in where?

V-shaped sealing ring is an elastic rubber sealing ring with axial action. It is used as a pressure-free seal for rotating shafts. The sealing lip has good fluidity and adaptability, which can compensate large tolerances and angular deviations and prevent internal grease or Oil leakage prevents external splashing or dust intrusion.

O-rings are mainly used for static sealing and reciprocating sealing. When used for high-speed rotating sealing rings, they are limited to low-speed rotating sealing devices. V-shaped sealing rings are generally installed in rectangular grooves on the outer circle or inner circle to seal.

Y-shaped sealing ring is widely used in reciprocating dynamic sealing device.

Uses: Used to seal pistons in reciprocating hydraulic cylinders, scope of application: TPU: general hydraulic cylinders and general equipment hydraulic cylinders, CPU: hydraulic cylinders and high temperature and high pressure cylinders for construction machinery, material: polyurethane TPU, central processing unit, rubber.

Use a rotary shaft lip seal made of Viton.

If an O-ring is used, it is recommended to add an elastic pressure to the sealing ring to keep the sealing surface in contact, but the effect is not very ideal. It is recommended to use a skeleton seal and try to use a mechanical seal. Generally, a bearing is required for rotation. The bearing cover should be pressed tightly, and the sealing ring should be installed on the bearing gland.

Depending on the sealing material and the degree of sealing, there are a variety of sealing methods: rubber seals, packing seals, mechanical seals and labyrinth seals are common.
