First, what is the dust ring?
The reciprocating seal mounted on the piston rod to prevent external dust from mixing into the hydraulic cylinder is the dust ring.
Second, what are the precautions for the use of dust rings?
1. No matter what kind of dust ring, it can not be pressured. In addition, the dust ring does not have a sealing function, and its attention role is to prevent dust (and also needs to be used with other seals).
2. Avoid cutting caused by contact between the lip of the dust ring and the opposite side of the wrench or the piston rod hole.
Third, the main role of the dust ring is?
The dust ring is mainly applied to the hydraulic pneumatic piston rod, so its main role is to remove the dust attached to the external surface of the piston cylinder and to prevent sand, water and pollutants from entering the sealed cylinder. In fact, in fact, most of the dust rings we use are made of rubber materials. Therefore, the dust ring is characterized by dry friction (which requires the rubber material to have particularly good wear resistance and relatively low compression permanent deformation properties, etc.). Fourth, what are the product types of dust rings?
With the change and development of science and technology, the product types of dust rings have also begun to enrich. According to the function, sealing mechanism, characteristics and structural types, dust rings can be divided into many types.
1. According to the structure, the dustproof ring can be divided into rectangular dustproof seal, J-shaped dustproof seal, chamfered dustproof seal, foot dustproof seal and triangular dustproof seal.
2. According to the function, the dust-proof ring can be divided into single-acting dust-proof sealing ring and double-acting dust-proof sealing ring.
3. According to the skeleton, the dust ring can be divided into a skeleton dust seal and a skeleton type dust seal.
4. According to whether the combination is divided, the dust ring can be divided into a single type dust sealing ring and a combined type dust sealing ring.
