Q:The difference between asbestos free gaskets and non asbestos gaskets

Because no asbestos gasket series not only has high strength, but also has good resiliency, and has strong anti permeability, therefore they are excellent environmental protection in automotive and industrial machinery replacement of asbestos gasket 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?

Imported generally coated with sealant, so after opening and then installed on the die

Q:What material is good for sealing gasket of steam pipe?

if it is oil, see what is there, such as phosphate oil, then use the fluorine rubber,

Q:Installation requirements for gaskets

1, the installation and the sudden plane flange matching sealing gasket, should pay attention to ensure that the sealing parts and pipes concentric, generally use additional strong ring and bolt internal circumferential contact to locate, not allow eccentric installation. When installing the basic spiral wound gaskets in the close flange of the mortise and tenon surfaces, the gap shall be kept in line with the groove wall.2, installation of the narrow width of the metal gasket, should be a certain thickness of the gasket plate on the outside, and then press the flange, so as to avoid compression filler metal gasket in the metal shell, the interface (or interface) burst damage, metallic gasket.3, when the flange work temperature is higher than 200 degrees, in the flange sealing surface and sealing gasket should be painted with sealant, in order to prevent high temperature sealing gasket and flange sealing surface sintering, to repair and replace the gasket to increase trouble.4, sealing surface is not normal, can be coated with sealant on the sealing surface, and then install the gasket. The sealant generally consists of red lead, manganese dioxide, graphite powder and boiled linseed oil (oil) formed after. According to the sealing medium, working temperature and medium pressure and other conditions, choose the corresponding types and grades of liquid sealant.5, for the installation of octagonal metal ring gasket, when the metal ring gasket and flange sealing groove processing is not ideal, can be achieved through research and close fitting. For large diameter metal ring gaskets, it is difficult to match and grind. In order to fill the tiny surface of metal surface, sealant can be used.

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:What's the difference between the gasket and the washer?

Other uses are used as spacers, springs (Baer, gasket, wave washer), wear-resistant pads, pre display devices, and locking devices. Rubber gaskets are also used on taps (valves) to cut off flowing liquids or gases. Rubber or silicone gaskets are also available to reduce vibration of the fan. Usually the outer diameter of the gasket is about two times the inside diameter.

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:Is there any prospect? Promising, which company in China to do this more professional?

Therefore, asbestos free products are very promising and promising. You can take a look at this company, Shanghai cord sealing materials Co., ltd..

Q:Why can the pressure resistance of the hydraulic cylinder be increased when the PTFE gasket is placed under the Y sealing ring?

The groove of the seal is gap and will be extruded from the gap after high pressure, which will affect the sealing, pressure maintaining and durability. Therefore, when the seal needs to withstand higher pressure, increasing the PTFE is a good choice!
