Introduction Of Different Type Dust Seals
Oct 14, 2021
The main function of the dust ring is to remove dust, sand, rain, frost and other dirt attached to the outer surface of the cylinder by the reciprocating piston rod, and to prevent external dust and rain from entering the inside of the sealing mechanism. A good dust ring should have a sharp lip structure and a low coefficient of friction. This can prevent external dust from entering the system and also reduce the wear of the equipment.
1. Hydraulic wiper seals DSZ is a combined seal with a sealing ring and an O-ring structure. The sealing ring is made of PTFE, nitrile rubber and fluorine rubber, and the color is generally coffee, yellow, black, green etc.
2. Hydraulic cylinder wiper seals DSZL is thinner than the above hydraulic wiper seals DSZ, so it is called a thin combined sealing ring, which is generally used in ceramic equipment, heavy-duty oil cylinders, injection machines, hydraulic presses, and metallurgical equipment.
3. Composite double wiper seals DPE can also be called PTFE seal, and the material is also PTFE. It is a special seal ring for oil cylinder seal and cylinder seal. The different models of the same name have composite dust seals DPR.
4. Saddle-type scraper rings DAM is especially suitable for adopting or customizing sealing materials such as PU, rubber, PTFE, because its elastic material has high hardness, good sealing effect, excellent wear resistance and low compression performance, and can be used in For most applications.
5. DSH dust seal ring is divided into ten different models:
Dust ring DKB
Dust ring DKBI
Dust ring DSZ
Dust ring DSZL
Dust ring DPE
Dust ring DPR
Dust ring DAM
Dust ring DAI
Dust ring DAH
Dust ring DBH
Generally made of polytetrafluoroethylene (PTFE) material; The sealing material used may be customized to polyurethane, rubber, or PTFE. Dust seals are mainly used as one of the special seals in the iron and steel industry.
The structure of the dust-proof seal ring is diversified, and the seal of each structure of the sealing device has a certain working endurance, temperature and application range.
