Detailed description

Yellow Kevlar fiber 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: The engine cover, or valve cover, cylinder head cover, the cover is the engine.This is my graduation project... The NASTRAN is used, but the rest of the software is basically the same.Hope to have experienced master Zhidianmijin ah.At present, only 12 order free modal analysis is performed. The final is to do static strength, sealing. The details of the process are not clear. For example, how does the bolt hole bind? Does it hold all the points on the inside surface? What about the boundary conditions and loading? It has more than ten bolt holes, one ring gasket, and 120 0.7bar pressure inside. The material is engineering plastics.Or some people know the whole process from modeling to the results of the general steps to say, you can, thank you first. OK, add more. StopFrequency response and transient response are currently being done: Such a professional problem, or experts answer better.

Q: Filter replacement did not find a small ring, so there is no problem for the filter: Hai Yu filter tells you, friend, that's a big problem. Is the filter closed and the sealing ring not leaking? Generally, the filter has a sealing ring. If you use the old machine to filter the sealing ring, it is recommended to change immediately, the sealing ring will be aging, easy to crack, oil spills.

Q: The material column of some gaskets / gaskets indicates what "200HV" means Is that the hardness scale? What materials are usually used? Know the elders please advice, little brother is not very grateful!!! []: Surface hardness of Vivtorinox, generally require no less than the number of commonly used non-ferrous metals, such as bronze, tin, bronze and so on

Q: The outer ball tooth ring sensor mud suede cover gasket what use to send: In the light seal, as well as the use of rubber bellows as an auxiliary seal, rubber bellows elastic limited, generally need to be supplemented with spring to meet the loading elasticity. Mechanical seals are often referred to as "mechanical seals"".

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: Does the seal used in the pneumatic hydraulic industry contain fasteners, gaskets (stainless steel, copper, aluminum, nylon)?: Usually, copper can be made into copper gasket and used as hydraulic seal. Others have never heard of it. Stainless steel is too hard, aluminum surface roughness is too low, nylon does not engage in oil corrosion, it is not appropriate to do hydraulic seals.

Q: Figure 3 gear pump in the rubber seal gasket, draw the assembly plan, you need to draw the gasket out? How thick is the painting? The graph doesn't give it the relevant size.: Can be black, but the number should be marked in the material.

Q: Does the gasket have brass? What's the standard?: In order to achieve the sealing effect, the annealing treatment is usually carried out before the use, the purpose is to make the copper sealing ring soft, so as to achieve better sealing effect

Q: Will the pipe flange be welded with graphite gaskets?: 1, pipe flange connection, welding flange, graphite gasket can not put in, otherwise it will burn graphite pad.2, the flange connection of the pipe, no matter what kind of material used in the gasket, are completed in the welding process after adding gaskets, to avoid welding when the high temperature of the arc burn gasket.3, welding fixed mouth flange, should be in the flange joint surface pad insulation object, prevent electric spark broken bad sealing surface. Only when the flange temperature drops below 60 degrees can the gasket be added, the fastening bolt is completed, and the connection procedure of the flange is completed.

Q: Engine oil tank seal is not strict, how to do the oil spill?: The chassis leak need to determine which parts, if it is the oil tank gasket seepage oil, replace the gasket can be, and if it is oil leakage, replace a new gasket should be ok. Clutch height may be the clutch plate wear seriously, clutch hard and press plate have certain relation.
