Introduction to the Characteristics of Stefon

The development prospect of this industry is very good, because it brings more benefits to the enterprise when it is used, so it is favored by customers. In order to make everyone more familiar with it, understand its characteristics and better bring benefits to the enterprise, next we will talk about the small knowledge points related to it, hoping to bring help to more people, let it bring more benefits.

In order to make everyone more familiar with it, understand its characteristics and better bring benefits to the enterprise, next we will talk about the small knowledge points related to it, hoping to bring help to more people and make it bring more benefits.

First of all, we have mastered the sealing characteristics of the seal from so many years of production and experiments, and we can alsoIt is divided into four areas: sub-sealing area, sealing unstable area, sealing area and sealing failure area. And in the process of use, the characteristics of their four areas also need to be mastered, so as to make it play a greater role. So when the pressure is0-0.6MPaWithin the scope, the seal will always be in a sub-sealing state, and its hydraulic oil will leak very little through the gap, almost close0Therefore, the sub-sealing zone can be considered to be in a sub-dynamic equilibrium period. And whenStefen'sPressure0.6-1.5MPawithin the range of the seal becomes unstable zone. This is because with the oil pressurePThe sub-dynamic equilibrium inside it will gradually be destroyed, and the internal leakage of the hydraulic cylinder during the sub-sealing period will gradually increase.QIncrease, the sealing performance of the seal is in the sealing instability zone. So when it can meet the hydraulic cylinder working night and pressure resistant state of the sealing requirements, it belongs to the normal working pressure zone. This time it's pressurePapproximately in3MPa-32MPaBetween, at this time, in oil pressure andOUnder the action of comprehensive factors such as the squeezing force of the ring, the slip ring and the surface of the metal part will be tightly cut together, and only a thin oil film is formed between the sliding pairs. This isSealed area of the stethseal.

And if StyphonOil pressure of the hydraulic systemPIt is greater than the pressure resistance of the seal, and when it continues to rise, the sealing of the seal will be destroyed, and the internal leakageQIncrease, at this time isSealing failure zone of the st seal. So when this happens, if used improperly, there may be a phenomenon of cracking slip ring, resulting in seal failure. If Stent sealWhen it is in the seal failure zone, its oil pressure will have a destructive effect on the hydraulic cylinder and the sealing ring. In the industrial field, the seal is generally made of a rubber.OThe combination of ring and PTFE ring. And in the pipeline of its hydraulic system, there are often relief valves and pressure reducing valves or pressure limiting valves to protect the hydraulic system. And in the shaft seal, it is suitable for the shaft (piston rod) hydraulic system and reciprocating motion, and in the high, medium, low pressure and heavy load, high frequency working conditions under the sealing occasionsThe characteristics of Stella are also very good.
