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: What are the standards for sealing gaskets? Urgently, hope you sent me in the following or recommend this standard website to me, thank you.: 1, GB4622.2-93 spiral wound gasket pipe flange size series 2, GB9126.1-88 plane type steel pipe flanges with asbestos rubber sheet, 3 GB9126.2-88 convex type steel pipe flanges with asbestos rubber sheet, 4 GB9126.3-88 bump with asbestos rubber sheet surface of steel pipe flanges and look at the details of reference seal mechanical seal technology network network

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: Pictured above, the red circle is directly in the processing of A plane with PTFE gasket compression seal, but always leak, I think it is in the corner due to leakage when processing make fillet PTFE gasket is not very good and fit to face A. Now I want to processing into the structure shown below, put a circle at the corner where the processing tank, which can fit the PTFE gasket A good surface, but also not to experiment, did not know that it is okay, there is no expert advice!The main problems are as follows:First, is this the cause of the leak?Second, A surface in processing, roughness and flatness should be processed to how much more appropriate?Third, how about the tolerance of key dimensions?: 1, is a form of change, whether can use stainless steel plug screw with PTFE raw material belt canal seal.2, material selection, can choose bulk PTFE, can overcome the roughness of processing

Q: What is the gasket BGS-3000?: PTFE suspension powder is indispensable

Q: How can the swivel washer be disassembled and replaced? Which God knows how to change the gasket? The faucet leaks. Maybe the washer is broken: You see the faucet switch that there should be a glue brand OEM OEM, put the Alice down, there is a screw removed, and then put the switch part rotating down, there should be a brass valve, with a bayonet on the spool, direct screw buckle will be able to get out of the valve core. The inlet valve is closed and then engaged.

Q: It is urgent to have a spring self sealing ring. The detailed parameters will be listed in picture form, and the quality will be better: Spring self sealing ring, such as parameters: outer diameter 36mm, the internal diameter of 21mm, you know the line diameter is 2.5mm; height is 8mm, please ask the number of turns or the pitch is? You'd better attach a physical map. I am the manager of spring machine. I have been engaged in CNC spring machine industry for many years. Many kinds of spring products have been researched.

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.: Drawing assembly drawings must be drawn at the same time indicate the gasket, the standard number, because the regular assembly drawing shall also have the parts list, those parts need to be purchased, which is homemade, and so on, at a glance, as the thickness of the gasket, with the actual size picture, otherwise it will affect the length of the shaft and fixed bolt.

Q: How do you use them? One hundredAre there any expanded PTFE gaskets in China? How about with Joe?: There is no substitute for gaskets on flanges

Q: Metal winding gasket, metal tooth shaped gasket, reinforced graphite gasket, metal coated gasket, thank you prawns: There are many types of customers, and all factories that use pipelines, equipment, transportation and handling of certain process media can be final customers. There are many ancillary equipment manufacturers. The owner of the new project, the Design Institute, the construction side.

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.
