Q:What can replace the car oil screw gasket?

The raw meal band can be substituted. More wrapped around the raw meal on the line. There's something wrong with the car. Ask the car master. 4S shop professional technicians, 10 minutes to solve. ]

Q:The plastic flange diameter 500, tried polytetrafluoroethylene PTFE gasket, sealing tape, but are unable to achieve the ideal sealing! Find the material that is resistant to hydrofluoric acid to be used as gasket! The test pressure is 2 kg!

Kunming Economic Development Zone, the morning fluorine plastic factory plastic experts to answer as follows: your larger diameter, but the pressure is not big, PTFE itself is one of the most corrosion resistant material, so the choice of PTFE material right, you should be made into thin gaskets, washers, must be modified to PTFE, reduce creep

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!!! []

The material column of the gasket / gasket indicates that 200HV is material and the mechanical grade is steel 200HV.Examples of marking: standard series, nominal size d=8mm, performance rating 200HV, plain gasket without surface treatment: gasket GB97.1 - 858 200HVA part that is attached between a connecting piece and a nut. A generally flat metal ring used to protect the surface of a connecting piece from the scratch of the nut and to distribute the pressure of the nut on the connecting piece.

Q:As shown in the figure below standard water pressure 0.7Mpa plastic PP products, from the end cover and cylinder body, the use of screw tightening, end seal. Is the O ring reliable, or is the gasket reliable, or any other sealing structure? The end cover needs to be removed and replaced during maintenance

O ring is generally good. But in your drawing, the sealing ring is easy to damage, and you need to put on the washer. Change the position, in front of the thread.

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

What a big question you asked! I'll tell you a little about it. I hope it will help you.Let's first talk about frequency response analysis!1. study the specialized finite element mesh division soft (HyperMesh)If you have plenty of time, first learn about the finite element mesh, like Hypermesh. The mesh is pretty nice. And you'll probably use it later on,.2. establish the calculation modelGroup the mesh models into Patran, and then combine them with paste and other functions. As for the bolt hole, you can fix the inner surface. If someone asks you for a reason, you can say that the result is conservative, and that's how it works in Engineering3. detailed steps, you can find reference books.I haven't done it myself for tightness. I'm not sure about my point of view. First of all, the problem is thermal gas solid coupling. Ha ha, seems very complicated. I don't know. I understand, right?Suggest you change ABAQUS software, try it. I'm not sure. There are plenty of examples in each software that you can take a look at. The ABAQUS help file has examples of thermal coupling and fluid solid coupling. You combine these two examples to see. What might be like?

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:Method for using gasket free sealant

Features and uses:Excellent oil resistance, water resistance, weather resistance, excellent sealing performance between 60~260 DEG C, thixotropy, no flow. Can replace the gasket for cars, motorcycles and all kinds of machinery and equipment of engine, gear box, axle flange joints and other parts of the implementation of seal, widely used in various parts of the mechanical seal (gap 6mm).

Q:What kind of hardness is used to measure the hardness of gaskets, gaskets, gaskets and O rings?

It's all rubber, but if it's Shaw's hardness tester, but you'll have to figure out Shaw's hardness tester. There are two kinds of HA and HD, one is soft rubber, one is hard rubber, and that's what you look like!

Q:BMW X5 engine gasket oil permeability to the engine to add what gasket is sealed

That shouldn't be the case for BMW. The reason is that the engine gasket aging to save money, buy a few barrels of good imported sealant, generally between 15-30, directly to the sealant gasket in the original position on a line, you can also get down, look like shape forming, with the original car mat. Note that buy bad glue, yes

Q:What kind of gasket does flange have? What standard does it have?

Non metallic flat gaskets for HGT 20606-2009 steel pipe flanges (PN Series)
