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: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:Imported washer, gasket, inch, JB982 combination washer, rubber gasket: Silicone rubber gasket is referred to as WMQ, silicone rubber has excellent resistance to high temperature performance, keep good elasticity in the temperature range of -70 DEG +260 DEG C, and has the advantages of ozone resistance, weather resistant, suitable for the thermal mechanical seal gasket.

Q:I would like to ask how that kind of sealing gasket is made and processed. That's the kind of gasket that is thin in the bottle lid. What kind of PE material can be worked out with a machine and a grinding tool? ~ thank you ~!: The mould calculates the size of the gasket according to the bottle cap, then opens the mold according to the size of the gasket, then puts the raw material of the gasket into the mold, applies the press to the pressure, and finally processes the gasket

Q:I found that the hydraulic joint can be used as a gasket with an aluminum pad or a copper pad, and the effect is good, but I don't know if there will be any other effect after repeated disassembly or long serviceImports of hydraulic equipment in the middle of some even no sealing ring, but spent more than ten years will not leak, but after opening and then installed on the failure, why?: 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.Imported generally coated with sealant, so after opening and then installed on the die

Q:Gaskets / seals, where are those / manufacturers available?: 3, piston special sealing ring: (lips mouth sealing ring: SODI, YXD, UNP, UHP, KDAS, SPGO)

Q:If the double gasket 1mm per piece, and the single layer gasket 2mm, which sealing effect is good? Is there any basis? I remember that the pressure wells in the family used double layer gaskets to solve the problem: Should be in the same preload, the gasket between the compensation of each other, more conducive to liquid sealing.From another angle, the pressure is higher, or the temperature is higher. In this case, with two gaskets, the two pads increase the chance of leakage due to the poor wear of the gasket in harsh conditions.You mentioned home pressure manhole covers use two pieces, because he is mainly used for sealing air and water, the environment and medium simple, while some of the industrial standards of the time limit. I am impressed, the home of the pressure covers also used waste tires, cut the gasket.However, in terms of sealing effect, it is generally not recommended to use both sides of the gasket. The effect of the monolithic shim is superior to that of the double wafer.

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:Should the rubber washer be placed above or below the gasket?: The rubber pad is placed between the iron gasket and the machine to seal, shock absorption and prevent the screw from breaking the rubber pad.

Q:such as metal winding gasket, flexible graphite composite pad, metal gasket, asbestos pad and so on. 10Ask again, how much money does it cost to ask so many devices?: The metal pad 1500 a small winding machine, spot welding machine open graphite 500---4000 block, 1500----5500 block, composite pad double shear machine 5000 blocks, 1500 blocks of single shear machine, coating machine 8000 pieces about such a price, do the math.

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
