The function of the dust-proof ring is really not small, but before using it, it is necessary to understand clearly its purpose and classification, so as to know which one is more appropriate for you. Following small to tell you about what it means dust ring and dust ring which can be divided into several.
What is the dust ring ?
1, dust ring This is its main role is to remove the reciprocating piston rod exposed on the external surface of the cylinder attached to the dust, sand, rain and frost and other dirt, this product is also it can prevent external dust, rain into the Inside the sealing mechanism. If a good wiper ring should be a sharp lip, low coefficient of friction. This can prevent the outside dust from entering the system, and at the same time, it can also reduce the wear of the equipment.
2. Application field It is used for oil cylinders or transmission shafts. For example, it uses a PTFE frame and O-ring structure as a dust-proof ring for the PTFE dust-proof ring. It can also be used as a dust-proof device in a bad environment and has self-lubricating properties. Sex. At the same time, this also protects the piston of the cylinder from being damaged by dust.
Which can be divided into several kinds of dust ring?
It is also divided into several types of dust ring, can be divided into lip dust ring, special Kang combination dust ring, Zork combination dust ring, which can be divided into a lip-shaped dust ring with skeleton lip shape Dust ring, no skeleton lip wiper.
1, the skeleton lip wiper: This product is the use of the frame and cavity hole interference to achieve anti-off, dust ring lip and cylinder head flush, this structure is to make the lip The mouth is protected from external damage. Relatively speaking, this type of product is used in occasions in which the lip of a walking machine such as a construction machine or a garbage truck is easily damaged.
2, no skeleton lips wiper: It is installed in the closed groove in the front of the cylinder head, the design of this product it must be slightly protruding the end of the cylinder head, so it is easy to remove the lip block Out of dirt. The structure is easy to install, relatively speaking, the application is relatively wide, and can be used for general industrial hydraulics, walking hydraulics and pneumatics.
3, special combination of anti-dust ring (PTFE + rubber): This product is the use of (O-ring elastic wear PTFE lip wear compensation in real time, with different Material O-ring can be used for high speed, high temperature and special working media.
4, Zocor combination dust ring (polyurethane ten rubber): This product it will not be commonly used, the structure of the combination with special Kang dust ring, the difference is that the polytetrafluoroethylene (PTFE) part changed to polyurethane (PU). This product also uses the elasticity of the O-ring to compensate real-time wear of the worn polyurethane (PU) lip. This product has the advantage of longer life than the ordinary lip wiper.
Summary: What does this mean about the dust ring and dust ring which can be divided into several related content on the introduction to this, dust ring is also divided into several, you choose when to be based on your use, different The type of its use is still very different, I hope the above introduction will help you.
