Detailed description

Graphite packing

Seiko graphite as the main material compiled. With good self-lubricating and thermal conductivity, low coefficient of friction, versatility, flexibility, high strength, has a protective effect on the shaft and so on. Depending on the requirements, can be carbon fiber, copper, 304,316 L, Inconel alloy wire and other materials strengthened. Mainly used for high temperature and pressure conditions.

Q:Finite element analysis of engine hood, tightness, structural strength analysis 160
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:Can gb/t97.1 be used for sealing?
GB/T 97.1-2002 flat washer level aThis standard specifies the nominal specifications (thread diameter) for 1.6 ~ 64mm, standard series, hardness class 200HV and 300HV grade, product level is a class of flat washers.
Q:Plastic flange sealing gasket 5
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:Why don't gaskets use metal gaskets in general?
The sealing gasket is made of metal or non-metal plate material, and is made by cutting, punching or cutting. The sealing gasket is used for the sealing connection between pipes, and the sealing connection between the parts of the machine and the parts of the machine.
Q:How can the seal on the spark plug be removed?
You can use oil (preferably diesel), dip (pay attention to dip washers only), and then gently use a knife and other thin tools to pry.
Q:What is the material of the metal ring? And the copper pad is better than that one
The ring includes a metal ring and a rubber gasket. Metal ring anti rust treatment, rubber ring generally use oil resistant nitrile rubber or fluorine rubber. Combination pad has metric and imperial two kinds of sizes, have standard JB982-77 set combination pad metal pad plus rubber form of combination. Combined sealing washer for threaded pipe joint and sealing plug, it is generally and bayonet ring couplings used together to block the oil inlet end is mainly used for hydraulic valve pipe joint screw joint static seal face for British and American Standard thread and the French and German standard metric thread connection of the static seal etc..
Q:What happens when the pressure on the gasket exceeds the maximum pressure?
Leakage is divided into flange leakage and blow out, the flat gasket will be blown out, winding gasket fracture and surface leakage!
Q:Is there a gasket 5 for screws?
Use a combination pad; the outside is iron. Inside is similar to the O ring soft plastic, mounted in it, you can go to the hardware store to see.
Q:Hydraulic joint with copper and aluminum gasket than rubber gasket will be more durable, sealing performance will be better?
The metal pad before using the best grinding, long time use is also good, but now the popular seal combination, inside is rubber, the outer ring is a metal skeleton, but also the price is disposable, and metal pad almost.
Q:What is the function of the washer between the end cap and the case?
1, the role is to cushion the amount of thermal deformation reserved.2 gasket refers to the pad between the connecting parts and nuts. 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.3, the gasket is divided into: -C, flat washer washer -A and grade C, grade -C large washers, washer, flat washer, flat washer, chamfered - - a grade steel structure with high strength washer, spherical washer, taper washers, square taper washers, steel I-beam with square taper standard type washer, spring washer, spring washer, light heavy spring washers, lock washers internal teeth serrated lock washers, inner and outer teeth lock washers, serrated lock washers, single ear washers, ears washers, external tab washers, round nuts with washers.
