Generally speaking, engineering machinery seal repair kits are composed of O-rings, hole seals, shaft seals, and dust rings. The details are as follows:
O-ring: Generally used as a static seal. If the working pressure exceeds 20MPa, it is generally necessary to add a back-up ring made of polytetrafluoroethylene (PTFE).
Hole seals: Common ones include V-shaped rings, U-shaped rings, Grain rings, combined sealing rings, etc., namely: V-shaped rings for holes, Grain rings for holes, U-shaped rings for holes, and combined sealing rings:
V-shaped rings: generally used in heavy-duty hydraulic cylinders, with reliable sealing. They generally need to be installed back-to-back in pairs with open grooves. For this type of sealing ring, the guide element generally uses a copper sleeve.
U-shaped rings are the most widely used and have reliable sealing. Many engineering oil cylinders and water conservancy oil cylinders use this sealing type. Open grooves or closed grooves can be used, and many of the guide elements use guide belts.
Grain rings are generally used in situations where the requirements for internal leakage are not too high, because the material of this sealing ring sealing slip ring is mostly made of PTFE + 30% or more copper powder. This material has a large internal leakage value under low pressure. The more pressure
The higher the sealing effect, the better. Servo cylinders generally use this type of sealing ring. Most of its guide elements use guide belts.
There are many types of combined sealing rings. Many manufacturers imitate the DAS sealing ring of Baosexiaban Company and design it. Generally, cylinders with compact structure and size are used. This sealing ring has a guide element and uses this
After installing the sealing ring, no other guide elements can be added.
Shaft seals: Common ones include V-shaped rings, U-shaped rings, Stern seals, etc.
Special seal: This kind of sealing ring is widely used. It is generally used as the first seal (i.e. main seal) in the piston rod sealing system. This sealing ring has oil return properties (i.e. the leaked oil can be brought back when the piston rod retracts. return)
