Q:How are ceramic and metal sealed joint?

If it is static sealAxial, O ring or flat gasket can be used; radial O ring can be used.If it is dynamic seal, in addition to radial seal, but also consider whether the need for axial dust ring.The end face seal has a special sealing ring, and the lip is contacted with the ceramic surface.For reciprocating motion, a combination of O rings or other cross sections can be used.

Q:It's three yuan ethylene propylene sealing stripEPDM rubber sealing strip production enterprises are relatively concentrated or relatively large scale

Q:In the seal of hydraulic cylinder, the O-ring and Y ring are sealed well

Y ringIn my opinion, it is generally applied to areas with lower pressure. Good sensitivity, quick response, good control.The ring of BingleyIt's hard to resistIts sensitivity is slightly inferior to that of the Y ring.

Q:How to choose the sealing ring material, sealing ring of different materials, what is the difference?

Insulation performance,butSILSilicone rubber sealing ring tensile strength than general rubber poor, and no oil resistanceSIL;The silicon rubber sealing ring is suitable for household electricityAppliances such as electric water heaters, electric irons, microwave ovens, etc.,

Q:What's the difference between a seal and a sealing strip?

There are so many seals that you can use them where they need to be sealed. Powder focus can be used to make seals.

Q:How about the sealing ring for the piston rod seal?

Previously, the piston rod seals were mostly made of O - shaped sealing rings, narrow section Y - shaped sealing rings and V - shaped sealing rings. Because of the dry friction between the piston rod and the seal, these seals often lead to premature wear of the sealing lip. In the past, the piston rod seals were mostly made of O - shaped sealing ring, narrow section Y - shaped sealing ring and V - shaped sealing ring. Sealed with the sealing structure and common rod which allows ring velocity are relatively low, so it is widely used in motor speed are not high, such as engineering machinery, metallurgical equipment, light industry and agricultural machinery hydraulic equipment.

Q:What are the common sealing forms of hydraulic cylinders?

The common sealing forms include clearance seal, friction ring seal and sealing ring seal. 1, the gap seal to rely on the relative movement of the small gap between the surface to prevent leakage. In order to improve the sealing capacity of the device, several small annular grooves are often made on the surface of the piston to increase the resistance of the oil through clearance. It has the advantages of simple structure, small frictional resistance, resistant to high temperature, but the leakage of large, high processing requirements, can not restore the original capacity after abrasion is only used in small size, low pressure, high speed of relative movement between the cylinder and the piston.

Q:Made the bearing oil seal O ring business for a long time, why not put up the quality of domestic?

Ha ha, now the high-end sealing products are basically occupied by foreign brands, NOK, Parker, good Wright, and so on. But now Taiwan seals are very expensive, you can choose Taiwan seals as an alternative,

Q:What type of sealing roller bearings.

The so-called bearing additional sealing performance device, that is, in the installation of end caps and other internal manufacturing into a variety of sealing devices. On the selection of roller bearings with a sealing Longma Xiaobian that should consider the following 6 main factors.

Q:What kind of seals are divided into?

According to the type of sealing structure, sealing mechanism, seal shape and material, the classification of seal is:Static seal1. gasket sealing (1) non-metallic gasket (2), metal metal composite gasket (3), metal gasket2. glue seal3. packing seal4. bellows
