Use:Extensively used in reciprocating sealing device, its existence is greater than the O-ring. Y-ring for the functioning strain of not much more than 40MPa, the functioning temperature of -thirty ~ 80 ordmC.
Y-ring in accordance with the size of the cross-EPT ratio of diverse, can be divided into extensive-type Y-ring, nEPT-type Y-ring and Yx-ring and so on. Vast EPT of the Y-ring strain resistance is somewhat more compact than the nEPT-variety Y-ring, can only implement to P lt20MPa working surroundings, and nEPT-variety Y-ring can be utilised for functioning stress P lt32MPa occasions.
Y-ring in accordance with the heigEPTT of the two lips are the identical, but also can be divided into shafts with unequal lip Y-ring, the gap with the unequal lip Y-ring and shaft gap widespread substantial-lip Y-type seal ring. Y-ring manufacturing materials are different, but also can be divided into nitrile rubber Y-ring, fluorine rubber Y-ring, polyurethane rubber Y-ring and so on. [one]
Operating velocity assortment: the use of modest eyes rubber creation is . 01 ~ .6m / s with fluorine rubber production, the .05 ~ .3m / s using polyurethane rubber production, in comparison with .01 ~ lm / s. Y-ring sealing functionality, support lifestyle and the doing work pressure of distinct Dang EPT limit, with polyurethane rubber material is EPT.
The Y-ring seals from its sealing lip by its open up lip. When there is no inner pressure, only a tiny make contact with force is generated because of to deformation of the suggestion. In the scenario of sealing, there is a normal strain equivalent to the strain of the medium at every position of speak to with the sealing medium so that the bottom of the lip ring will be compressed aXiHu (West EPT) Dis.ally and the lip will be compressed in the circumferential course to turn out to be wiEPTTin speak to with the sealing area, Even though the speak to anxiety boosts. When the inner stress and then increased, the get in touch with pressure distribution and measurement of the further modifications in the lips and sealing floor with far more closely, so EPT sealing, which is Y-ring quotself-sealing influence. quot Due to the fact of this self-sealing effect, a Y-ring can efficiently seal the higher stress of 32MPa.
The powerful sealing pressure of the strain-location seal is equal to the sum of the pre-stress and the fluid strain. Y-shaped seal by means of the position of the lip will be effective in the part of the fluid stress on the seal, the pre-force can be lowered to a tiny worth, and the increased fluid strain, the part of pre-strain in the large-force, the role of pre-anxiety can be disregarded ExcXiHu (West EPT) Dis.Hu (West EPT) Dis.. At this time, it is useful to reduce the sealing frictional power since the sealing frictional power is proportional to the sealing speak to force. So Y-shaped seal to guarantee that the seal at the same time, the friction is significantly less than the squeeze-variety seal.
Y-formed ring is mainly utilised for reciprocating seal, its operating theory, Y-ring set up, the lip to the side of the high force to engage in a position, so Y-shaped ring can only enjoy a position.
When the coupling moves at relative pace, a sealing oil film is shaped between the sealing lip and the sliding floor. The eXiHu (West EPT) Dis.stence of the oil film can improve the friction issue of the sealing ring and reduce the put on. The oil movie plaEPTTthe function of sealing in the pneumatic sealing. In the reciprocating movement of the EPT factor, the oil film thickness is distinct when the movable member is prolonged and retracted, and this accumulation of the film thickness variation causes the leakage. Consequently, the Y-ring normal work, there are really couple of leakage occurs, the reciprocating pace, the leakage quantity. This is simply because the reciprocating velocity, the frequency of reciprocating gets to be very frequent, whilst the oil movie fluid EPTT to improve the film thickness, the formation of the fast accumulation of oil film. When the viscosity of the working oil will increase, the oil film thickness increases, the reciprocating pace brought on by leakage also enhanced. Even so, as the EPT oil viscosity decreases with rising temperature, so the EPT equipment starts at reduced temperatures, the beginning of the movement of the greater leakage, with the motion due to various losses brought on by temperature increases, the leakage will progressively minimize back again.
Pistons in the reciprocating stroke of the leakage predicament is diverse. When the internal stress is lower, the volume of leakage in the extraction stroke increases with the increase of inside pressure, and decreases with the increase of the interior strain in the course of the pressing stroke. When the internal force is large adequate (about much more than seven.5MPa), the leakage will no EPTTer modify with the inner strain.
When the inner stress p1 Y-ring is lower, the friction increases with escalating internal strain. When the inner force is massive ample, the friction is no EPTTer a excellent modify. Such as great lubrication, or even a downward trend. EPT start on the Y-ring friction examination benefits demonstrate that the commencing friction and parking time has minor to do with the O-ring is the largest difference.
This is really useful for intermittent transferring EPTTry. At the same time, when the internal force is lower, the beginning friction boosts with the internal stress, when the internal stress exceeds 5MPa, the starting friction will be impartial of the inner pressure. So for large-force intermittent EPTTry, there will be no commencing friction is also large difficulty. Seal lip wear, owing to the role of media strain, lip with a particular diploma of automated compensation.
