Y-ring The Seal Acts As A Seal
Y-ring is mainly used in the hydraulic cylinder piston rod or piston seal, Y-ring seal can be divided into two kinds of pressure conditions, in the absence of media pressure when the lip only by the amount of pre-compression close to the seal To the role of the seal, with the media pressure, the media will be filled into the inner lip between the outer lips of the trough, respectively, the two lip to the pressure to promote the role of the lips up more open, and then close to sliding Parts, so when installed in the Y-ring when the cavity to the media installation.
Y-ring can withstand the maximum working pressure of about 20Mpa, when the pressure exceeds this value can help support the ring to keep the pressure to increase. Y-ring also has a certain self-compensation capacity, in response to the gradual wear and tear in use of the situation.
It should be noted that the Y-ring is suitable for medium and low pressure reciprocating seal. Such as piston and cylinder, piston rod and piston cover. It mainly rely on the lip close to the surface is sealed, and from the sealing effect. Therefore, the sealing lip is easy to wear and heat deformation. Therefore, the size of the lip is measured in the design and design, including the outer diameter of the lip, the diameter of the lip, the amount of pre-compression and the amount of the gap.
Y-type ring hydraulic cylinder exclusive ring, y-shaped ring is not so widely used O-type, but its importance is self-evident. Y-shaped ring there are many types, so the corresponding use of materials are more extensive, including the main polyurethane, Dingqing rubber, fluorine rubber, silicone rubber the following four.
Then the following Gaoke Rubber on the following four materials to do the following one by one to explain:
First of all, polyurethane, in the Y-ring of many categories of polyurethane is almost universal, each type of Y-ring can use this material. Polyurethane material compared to other materials is a major advantage of wear resistance. From the appearance can also be seen that the material produced by the Y-ring than other rubber hardness, good shape, which is because of the high brittle polyurethane material reasons.
Polyurethane material in the breakdown of the words can then be divided into TPU class and cpu class two, of which tpu is a rubber name, tpu name for the thermoelectric plastic polyurethane rubber, this material can be softened under certain heat, and at room temperature The next can be used to maintain the same effect.
The cpu is a resin class CPU with a wide range of hardness, high strength and elongation, excellent wear resistance, integrated performance is mainly used in the mining industry, as some of the raw materials industry.
