- Q: How much pressure can the aluminum gasket bear?
- Compared with other rubber, silicone rubber has excellent properties of high and low temperature resistance, waterproof, corrosion resistance, aging resistance, non-toxic, tasteless, elastic and so on.
- 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: Which kind of plate heat exchanger has the highest cost performance?
- Snap fastener type rubber pad, rubber pad, rubber pad buckle type, convenient installation and disassembly, most models of AI is Reed ARD, he is good.
- Q: Gasket free sealant
- The glue is pasty before it solidifies, like Ivory paste, sealed with an aluminum tube bottle. When it is used, squeeze the sealant out of the aluminum tube and apply it to the surface to be sealed to make a rubber ring.
- Q: Does the seal used in the pneumatic hydraulic industry contain fasteners, gaskets (stainless steel, copper, aluminum, nylon)?
- Usually, copper can be made into copper gasket and used as hydraulic seal. Others have never heard of it. Stainless steel is too hard, aluminum surface roughness is too low, nylon does not engage in oil corrosion, it is not appropriate to do hydraulic seals.
- Q: What kind of material is rubber gasket?
- The rubber gasket is a self expanding sealing gasket, belonging to the sealing component of the pipeline. The gasket is composed of an outer ring, the middle ring and the inner ring expansion of three parts; the outer ring and the inner ring is generally elastic sealing ring, the middle ring at the center of a ring on both sides of the bubble structure, hollow ring, outer ring seal ring outer ring and the inner side of the opening; the inner ring is divided into two parts installed in the middle, inside and outside the ring structure of the global expansion. There are many kinds of rubber gaskets, and the materials used for rubber gaskets are different. For example: if it is used in mechanical seals, generally need high temperature, oil and corrosion resistant materials, and if used in the food industry, you need more environmentally friendly, pollution-free material. Rubber gasket material is generally divided into: silicon rubber gasket, butyl rubber seals, nitrile rubber gaskets, silicone rubber gasket, three EPDM gasket, chloroprene rubber seal, polyurethane rubber gasket, hydrogenated butadiene acrylonitrile rubber gasket, fluorine rubber sealing pad of the 9 kinds of material. The above-mentioned 9 kinds of rubber gasket material has its own characteristics, so its use is also different.
- Q: As shown in the figure below standard water pressure 0.7Mpa plastic PP products, from the end cover and cylinder body, the use of screw tightening, end seal. Is the O ring reliable, or is the gasket reliable, or any other sealing structure? The end cover needs to be removed and replaced during maintenance
- The O ring can be used in general design, and gaskets are recommended in view of the need for disassembly
- Q: Will the pipe flange be welded with graphite gaskets?
- Not put, otherwise it will burn the graphite pad.Graphite gasket made of pure graphite or metal plate (tooth plate, plate, net) reinforced graphite plate cutting or stamping, has many excellent sealing performance, such as thermal stability, self lubrication, corrosion resistance, not aging, not fragile, the use of long-term stability in the harsh working conditions, rarely need maintenance. The lining materials are made of different metal sheets.
- Q: Buick air conditioning pipe gasket, how do you leak?
- Air conditioning refrigeration tubeChasing the answerChange the leakage of coolant, or not put the leather ring. Either the joint is corroded or the pipe is changed.
- 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.
