Detailed description

Carbon Kevlar packing

With aramid fiber as the main material, repeatedly dipping lubricants, lotions and other precision PTFE compiled. There is preferably a high resilience, chemical resistance, low cold flow and high line speed, and the comparison with other types of packing, the crystallization medium and the particles can resist higher temperatures. Can be used alone or combined with other packing. Mainly used for multi-media particles, easy to wear conditions.

Q: Why can the pressure resistance of the hydraulic cylinder be increased when the PTFE gasket is placed under the Y sealing ring?: The groove of the seal is gap and will be extruded from the gap after high pressure, which will affect the sealing, pressure maintaining and durability. Therefore, when the seal needs to withstand higher pressure, increasing the PTFE is a good choice!

Q: What is the difference between the sealing ring and the dust cap on the bearing?: Bearing belt, dust cover and sealing ring, two different performance. Refer toOne is dustproof and the other is sealed. Dust prevention is to prevent dust from entering the inside of the motor; the seal is not only not allowed by outside dust, but also not easy to flow out of the inner fat. Grease that is not clean is not easy to flow through. In practice, there is a difference between the two, but not too much. Bearings are generally internal and external oil cover, has played this role, only under certain conditions only need. Dust proof is indicated by Z and sealed by S. (felt ring seal is expressed by FS; rubber seal is expressed by LS).

Q: Gasket material? The role of materials?: Asbestos. Asbestos material has two kinds: wet asbestos and blue asbestos. Wet asbestos, heat resistance, good alkali resistance, high tensile strength, acid resistant performance is poor, the majority of asbestos rubber plate made from it; not only blue asbestos, good heat resistance, and acid resistance is also very good, so it is used in the manufacture of acid resistant asbestos rubber sheet. The normal use temperature of asbestos board is below 550 degrees. An asbestos or asbestos rope may be used for a larger pressure vessel. When asbestos ropes are used, they are usually impregnated with water glass. Acid, alkali, solvents and other media can also use such gaskets. Asbestos rubber sheet. Asbestos rubber sheet is made of asbestos, rubber and stuffing. Asbestos fiber generally accounts for 60%-85%. According to its distribution process, performance and application of different, mainly high-pressure asbestos rubber sheet, medium and low pressure asbestos rubber sheet and oil resistant asbestos rubber sheet. Asbestos rubber sheet has the properties of proper strength, elasticity and softness, and it is convenient and cheap to make gaskets. Therefore, it has been rapidly popularized and applied in chemical enterprises. Flexible graphite.

Q: Gasket is a kind of machinery, equipment, pipes and other internal sealing materials, which types are there?High and medium pressure asbestos rubber sheet gasket, oil asbestos rubber gasket, cylinder gasket, aramid gasket, non asbestos plate gasket, asbestos pad, PTFE lining rubber pad, I know that, there are other ones?Can anyone tell me what their scope of application is?: The new organization dense, molecular structure of non-polar, used as a gasket, contact surface can be smooth, the metal flange is not sticky. In addition by molten alkali metal and containing fluorine gas erosion, which is resistant to many kinds of acid and alkali, salt, oil solution of corrosive media. PTFE gasket including pure PTFE, PTFE or PTFE expansion. The semi metallic gasket (also called metal gasket). Non metallic material has good flexibility, compression and bolt load ability is low. But it is mainly to determine the strength is not high, poor elasticity, not suitable for high pressure temperature. So the combination of metal materials with high strength and good elasticity. Withstand high temperature characteristics. The formation structure is semi metal gasket. The gasket. Semi metal gasket are mainly metallic gasket, metal winding gasket, corrugated metal gasket, with metal serrated gasket with the metal. Gasket (metal gasket). The gasket to nonmetal material core, thickness of sheet metal 0.25-0.5mm outsourcing. According to the state of coating can be divided into coating, coating, coating and half wave Double coated sheet metal. According to the elastic-plastic material, heat resistance and corrosion resistance were selected. Mainly copper, galvanized iron, stainless steel, titanium, Monel alloy. It is widely used in copper, galvanized iron, stainless steel.

Q: How do I remove the rubber sealing washer for the washer inlet valve?: When the dirty water filter valve plug, usually use the brush will be able to solve the problem (without dismantling),

Q: Now the general O ring is used moreNon-metallic, non asbestos gasket, paper gasket, rubber gasket, insulation gasket and so on.But I think they're all the same in shapeWho can tell me the difference between the sealing ring and the gasket? Use or something else, thank youI know they are all a general name, and what I want to know is how to distinguish themAnd there's the difference: The difference is that the model and the location are actually a name, sealing ring. For example, in the use of O laps relatively large model, if you can just touch the so-called sealing gasket required model, you can directly take O ring as a gasket.

Q: Why is copper gasket always leaking out of the sealing surface?: The sealing surface of two different material substances in contact is generally cast iron, cast iron due to the thermal expansion coefficient of copper with different period of time when the heating operation of the equipment, will not leak in a short time, but when the device stops again after operation will be oil leakage.

Q: Buick air conditioning pipe gasket, how do you leak?: Air conditioning refrigeration tubeChasing the answerChange the leakage of coolant, or not put the leather ring. Either the joint is corroded or the pipe is changed.

Q: Good quality seals, which have, specializing in the production of rubber gaskets?: Hebei Qinghe Tianyu plastic products factory is a professional, they do the rubber seal (seal), manufacturers of large scale, long life, and has many large car manufacturers for many years, they have shown some online pad, other styles can be customized, contact with manufacturers and the Internet are very detailed.

Q: Installation requirements for gaskets: 1, gasket gasket and flange sealing surface should be cleaned, shall not have any influence on the sealing performance of scratches, spots and other defects exist.2, the sealing gasket than the flange sealing surface diameter should be small, the gasket diameter should be slightly larger than the inner diameter of the pipe diameter, two difference 2 times the thickness of the gasket, to ensure that the gasket is compressed, not into the inner edge of a container or a pipe, so as not to impede the flow of liquid container or pipeline flow.3, the gasket preload should not exceed the design requirements, so as to avoid excessive compression gasket, loss of resilience.
