Seal lips come in a variety of designs. This can achieve a good seal and reduce friction. In this way, the life of the seal is longer. The metal spring ensures that the seal lip is protected from leakage, even under no-pressure conditions. Make up for various thermal expansion phenomena.
1. What are the working conditions adapted to the spring energy storage seal ring?
A: The spring storage seal ring is suitable for all kinds of harsh working conditions from minus 260 degrees to 340 degrees above zero, 400MPa pressure difference, 3 to 4000rpm, except for a few extremely corrosive media (such as aqua regia, etc.), and can provide excellent sealing solutions.
2, is the sealing ring manufactured by the mold?
A: No. The outer jacket of the spring energy storage seal ring is made of engineering plastics such as telfon Teflon by a unique process of sintering and pressing into blocks with a mold free machining method.
3, how to guarantee the quality of die-free processing? Is it guaranteed that the quality of turning is the same for different batches?
A: Spring energy storage seals are manufactured by precision special CNC die-free machining equipment, taking into account the wear of the tool, and considering the temperature, humidity and other possible influencing factors of the manufacturing environment. At the same time, the PTFE material processing technology also ensures the uniformity of the material of the raw material. With multiple quality inspection and testing processes, the quality of the spring energy storage seal ring can be guaranteed to be constant and reliable.
4, hydraulic oil is very thin, easy to leak, spring energy storage seal can ensure zero leakage?
A: Absolutely. The spring energy storage seal ring can even seal the gas, liquid gas, etc., and the leakage level can reach the level of six leakage, that is, zero leakage. As for hydraulic oil, zero leakage can be achieved.
In general, the allowable leakage amount we hope to be proposed by the user, and then we design and manufacture the seal ring according to the demand.
5, the use of spring energy storage sealing ring whether the processing requirements for parts become higher?
A: No. For hydraulic oil seals, the processing accuracy of general parts can be between 0.8 and 1.6. At the same time, the spring energy storage sealing ring can be adjusted by adding different materials to the telfon Teflon material to adjust its own material hardness, self-lubrication and other characteristics, so as to better match the user's existing parts processing indicators, and better play the sealing effect. The ordinary sealing ring requires the user to adjust the material and processing accuracy of the part when designing the part, which not only increases the cost to the user, but also can not obtain the perfect sealing effect.
6. Does the spring energy storage seal ring need to be made into a split type sealing groove?
Answer: Answer: No, closed is also OK, you can use the installation tool to open the spring energy storage seal at a higher temperature to install it in place. Can also be used to open installation, the use of baffles, convex to complete the sealing ring fixed.
This is because only one spring energy storage seal can be used to replace the usual sealing effect of multiple O-rings, so it is completely possible to take an open baffle or convex installation, rather than having to consider the use of a troublesome closed installation.
7, spring energy storage sealing ring and O-ring advantages and disadvantages comparison.
A: O-rings have been widely used in the sealing field because of their low cost and wide application, but their disadvantages are also obvious, such as easy aging, easy cracking, corrosion resistance, high and low temperature resistance, high pressure resistance, friction resistance, short life, etc. Compared with O-rings, spring energy storage seals have excellent performance in these aspects. And it can also be enhanced by adding various materials in some aspects. For example, the addition of graphite can make the spring energy storage seal better lubricity.
The telfon Teflon jacket of the spring energy storage seal ring and the material and shape of the spring can be changed to obtain the characteristics required by the user, so its application range is very wide, and it can also meet many very fine and high requirements of the user, which are unmatched by the design and production of O-rings and other standard specifications of various seals.
Of course, the cost of the spring storage seal ring is correspondingly higher than the O-ring.
In addition, due to its excellent performance, in the case of several O-rings, generally only a spring energy storage seal can be required, which brings great convenience to the assembly, in general, only a baffle or a small boss can be required.
8. How much pressure can the spring energy storage seal bear?
A: The spring energy storage seal can be designed according to the actual needs of users, generally speaking, 400MPa pressure is no problem. If you need to withstand more pressure, you can also add some materials and special design to meet the requirements.
9, spring energy storage seals in piston, hydraulic equipment and other applications are there special design for dust and other requirements?
A: One of the characteristics of the spring energy storage seal ring is that it can be customized design, not only the size specifications and manufacturing materials can be customized design, but also for different working conditions to give special functional design, such as dustproof, anti-blowing design. Even as a hydrogen medium, the spring energy storage seal has considerable performance.
10, how long can the life of the spring energy storage seal ring be?
A: The life of any seal depends on its working condition requirements and the specific design of the seal ring. Generally, under static conditions, due to the anti-aging corrosion and other characteristics of the Teflon material used in the spring energy storage seal ring, its sealing can be maintained for decades. In general dynamic and even very harsh conditions, according to different designs, the spring energy storage seal can also meet the long life needs of users by changing some aspects of the characteristics.
These have far exceeded the performance of other seals available on the market.
11, how should the spring energy storage seal be designed?
A: As long as the user can give the detailed working conditions and groove size in the design stage, then we can carry out the design of the spring storage seal ring, if the groove processing is not very understanding, we can also communicate.
12. How long is the supply cycle of the spring energy storage seal ring?
A: Generally speaking, due to the factory to complete raw materials, design, scheduling, production, quality inspection and other procedures, so the supply cycle generally takes 15-30 days. In special cases, we can also provide special expedited delivery services.
13. Is the spring energy storage seal more difficult to install?
A: Whether it is good to install, mainly depends on the design, under normal circumstances, open grooves are better to install.
Is there less material available for spring energy storage seals?
A: Just teflon materials, there are more than a thousand formulations in the world, and we use more than a hundred of them exclusively as sealing materials. In addition, there are other engineering plastics such as PA, POM, PEEK, PCTFE and other engineering plastics; Rubber material is also the choice of spring energy storage sealing ring, such as NBR, HNBR, FKM, EPDM, SILCONE, etc. Of course, we also have special PU material can also be used to make spring energy storage seals.
14. Do you have other sealing rings to choose from?
A: STF has nearly 20 years of experience in the use of sealing products, according to the different working conditions of users, we have a lot of sealing solutions to choose from.
STF sealing sincerely look forward to the arrival of every user who has sealing needs, and contribute their own strength to the sealing of all walks of life in China, and realize the dream of sealing the country.
