- 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!
- Q: What is the function of the washer between the end cap and the case?
- To prevent wear, preload, good sealing, buffer, reserved expansion amount of the thermal deformation of the bearing in order to offset the series gap, bearing and motor end cover between the wave washer several special, and when the attention of effective face surface of the stator. The rotor of the quasi. A special wave washer prevents axial movement, i.e., moving at both ends of the shaft.
- Q: What is the difference between the sealing ring and the dust cap on the bearing?
- Dust cover: an annular ring made of thin metal plates, fixed to a ring or washer of the bearing, which covers the inner space of the bearing but does not come into contact with the other ring or washer.
- Q: Gasket material? The role of materials?
- There are many kinds of gaskets, which are divided into three major categories: nonmetal, semi metal and metal gasket. A non metal gasket. The non-metallic gasket is soft, corrosion resistant and cheap, but it has poor resistance to heat and pressure. Flange seal for medium and low pressure vessels or pipes used at normal temperature and medium temperature. Non-metallic gaskets include rubber mats, asbestos pads, asbestos rubber mats, flexible graphite pads and PTFE mats. Rubber sheet. The main materials for making rubber plate gaskets are natural rubber, nitrile rubber and chloroprene rubber. In addition, special rubber, such as fluorine rubber, has also begun to be applied. Rubber has compact structure, soft texture, good elasticity, easy to cut into various shapes, sealing and cheap, Tesco and other characteristics have been widely used in the container and the pipeline, but it is not high in mineral oil, easy to dissolve and expansion and is easy to corrosion, aging at high temperature, loss of resilience of.
- Q: Question: a position on the sealing position of copper gasket
- The copper gasket is generally used with thread sealing place, it is the principle of the sealing surface with two copper pad extrusion deformation, the copper pad two surface with two binding surface tightly without gap, so as to obtain the sealing effect.
- Q: Gasket, packing belongs to the scope of mechanical seals?
- Packing (packing), also known as sealing packing, is usually woven from a softer thread. Usually, the sectional area is square or rectangular, and the circular strip is filled in the sealed cavity to seal it. Packing is the first cotton fiber plug in the leak path to prevent fluid leakage, mainly used as seal water lifting machinery. As the filler has a wide range of sources, easy processing, low price, reliable sealing, simple operation, so far in use. Now the packing is widely used in reciprocating shaft seal of centrifugal pump, compressor, vacuum pump, mixer and propeller seal, piston pump, reciprocating compressor, refrigeration machine, and various rotating valve stem seal.The gasket does not belong to the mechanical sealing range, and belongs to the auxiliary component of mechanical connection.
- Q: Now the general O ring is used moreNon-metallic, non asbestos gasket, paper gasket, rubber gasket, insulation gasket and so on.But I think they're all the same in shapeWho can tell me the difference between the sealing ring and the gasket? Use or something else, thank youI know they are all a general name, and what I want to know is how to distinguish themAnd there's the difference
- As far as the distinction is concerned, from the model point of view, the O ring has a fixed model name. For example, 3.1*50., and gaskets have fixed models, such as oil seals, 45*60*7.
- Q: Is the raw meal belt not used to prevent leakage between the pipe and the pipe? But I see a lot of water heaters only at the cold water outlet (into the water heater and faucet at both ends) wrapped around the raw meal belt, and at the hot water outlet (shower) is not entangled, just put two pads. Is it okay to tape the raw material at the hot water outlet? I put two pads, and a little water seepage, can you put one more? What is the function of rubber pads? Under what circumstances do you need to use raw meal belts and pads? Thank youIn the picture, the middle pipe is hot water outlet (without wrapping the raw material belt, only two pads are placed), and the right side is cold water outlet (wrapped with raw material belt).
- The pipeline connection requires the use of raw materials, water interface generally use rubber pad, because the design interface nut only plays the tension on both sides of the interface distance, if used with raw materials, can be made of raw material with the annular sealing ring pad as the hot water outlet must be used PTFE pad, do not shoot hot, ordinary rubber mat preheating deformation.
- Q: The sealing principle of metal wound gasket?
- Sealing gasket: metal winding principle of the sealing surface when the pressure load, to produce compressive stress, can improve the sealing contact surface, when the stress increases enough to cause the surface of the plastic deformation obviously, it can fill the gap seal cover, plug leakage channel. The purpose of using the gasket is to use the gasket material to produce plastic deformation characteristics under the action of compaction load so as to fill the small and uneven surface of the flange sealing surface so as to realize the sealing.Leakage is the phenomenon that the medium enters the limited space from the outside of the inner space of the limited space or from the outside. This is what people do not want to happen. The medium flows through the interface between the inside and outside spaces, i.e., leaks occur on the sealing surface. The root cause of the leakage is that there is a gap in the contact surface, and the pressure difference and the concentration difference on both sides of the contact surface are the driving force of the leakage. Because of the sealing surface form and processing accuracy and other factors, the sealing surface of the gap is unavoidable, which will cause the sealing surface is not completely consistent, resulting in leakage.In order to reduce the leakage, it is necessary to make the contact surface to be fitted to the maximum extent, that is to reduce the cross-sectional area of the leakage passage and to increase the leakage resistance, and to make it larger than the leakage force. In the bolt flange gasket connection, the force of the gasket causes deformation of the gasket material so as to fill the gap between the flange sealing surfaces. The magnitude of its pretension depends on the number of bolts, the torque of the tightening bolt, the lubrication state of the bolt system, and the compression area of the gasket.
- Q: Is there any prospect? Promising, which company in China to do this more professional?
- In view of this particular case, we hereby reaffirm that all the gaskets we operate are asbestos free gaskets without any asbestos content. Unless otherwise specified, it will be explained in detail.
