DWCT
O-ring seal, with a circular section, simple shape, easy manufacturing, low cost, use the temperature range from-60℃ to 200℃.Using O-rings of different materials can mostly meet the requirements of various media and various movement conditions.
The O-ring has the following characteristics:
The ① sealing part is simple in structure, compact in installation part, and light in quality;
② has a self-sealing effect, often with only one seal can complete the seal, sealing performance is good, used as a static seal can be almost done with no leakage;
When ③ is used for reciprocating movement, the sealing performance in the reciprocating travel, the leakage is very small, only when the speed is high, some leakage;
④ movement friction resistance is very small, for the pressure intersection occasions can also adapt to;
⑤ size and grooves are standardized, low cost, easy to use and outsourcing.
