- Q: Classification of sealing strip by use
- Table 29.2-1 classification of sealsThe basic requirements of the seal is the sealing is good, safe and reliable, long service life, should be compact in structure, simple system, convenient maintenance, low cost, most of the seal parts, should ensure interchangeability, realize standardization and seriation.Various types of by sealing group leader have their characteristics and scope of use, the design of sealing should first be analyzed and compared.Table 29.2-2 lists the characteristics of a variety of commonly used sealing methods. Table 29.2-3 is the type and range of applications of dynamic seals.Sealing type, reciprocating motion, rotation, pressure resistance, high speed resistance, heat resistance, cold resistance, durability, remarksPacking seal pump, turbine, valve, autoclave. Available for filament packing, textile packing, or molding.O - ring seal piston seals are widely used as static seals, with good durability at this time.
- Q: The difference and advantages and disadvantages of single lip seal and double lip seal
- Ring seal generally refers to the buckle ring seal, the material is divided into metal and non-metallic. Common metals are mostly used in reciprocating motion.Lip seal generally refers to the outsourcing metal skeleton lip seal, metal and non metal lips, applied to rotary motion.
- Q: What is the optimum amount of compression for the seal? Is the amount of compression related to the material of the sealing ring? What is the relationship between the hardness of the sealing ring and the hardness of the sealing ring?
- Ding Qing rubber resistant mineral oil, silicone oil, animal oil, esters, HFA, HFB, HFC, air and water, water resistance increased with the increase of propylene, but low temperature and permeability decreased. Not suitable for phosphate system hydraulic oil and polar additives gear oil, suitable for temperature -30~100, generally used for O ring, oil seal and so on
- Q: What kinds of seals are there in SKF bearings?
- The 3. axis supporting structure has the advantage of allowing angular deviation;4. circumferential velocity of sealing surface;5. the working temperature of the bearing;6. manufacturing costs.
- Q: It's three yuan ethylene propylene sealing stripEPDM rubber sealing strip production enterprises are relatively concentrated or relatively large scale
- Glass bead, glass glue, glass of water, glass door seal rubber molded parts, mechanical seals, foam seals, seals, gaskets, rubber pad, three EPDM rubber molded products, silicone, transparent, dustproof, rubber (PVC), white, various types of color. All kinds of rubber, silica gel, rubber and plastic, three yuan ethylene propylene (EPDM) system
- Q: What is mechanical seal?Single mechanical seal? Double mechanical seal? What's the shaft seal?
- 2. mechanical seal is a kind of rotating machinery shaft seal device. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Due to the drive shaft through the inside and outside of the equipment, so there is a gap between the shaft and the peripheral equipment, equipment in the media leak out through the gap, if the device internal pressure below atmospheric pressure, air leakage to the equipment, so there must be a package of the shaft to prevent leakage. There are many kinds of shaft seals, because mechanical seals have the advantages of less leakage and long service life
- Q: How can the tapered roller bearings be sealed?
- There are many kinds of tapered roller bearings, I wonder if it is oil lubrication or grease lubrication? Dustproof or anti leakage?
- Q: Reasons affecting the tightness of cylinder
- 6 cylinder head flatness7, head of bolt preload8, cylinder head pad quality9 、 piston ring cylindricity and elasticity10 cylinder surface finish
- Q: What are the material requirements of the valve sealing surface?
- Sealant, liquid sealant, anaerobic adhesive gasket, pipe connection, thread sealInorganic materials, flexible graphite, natural graphite gasket, soft packing, sealing partsCarbon graphite baking carbon, anodized graphite, mechanical seal, hard packing, power seal, gap sealEngineering ceramics, alumina ceramics, talc ceramics, cermets, silicon oxide and chromium borideMetal, nonferrous metal, copper, aluminium, lead, zinc, tin and its alloy gasket, soft packing, mechanical seal, labyrinth seal, hard packing and gap sealFerrous metal, carbon steel, cast iron, stainless steel, surfacing alloy, spraying powder gasket, hard packing, mechanical seal, piston ring, gap seal, dust-proof seal, full closed seal, forming fillerTungsten carbide, cobalt carbide, tungsten cobalt titanium carbide mechanical sealPrecious metals, gold, silver, indium, tantalum, high vacuum sealed, high pressure sealed, low temperature sealedThe performance of the sealing material is an important factor to ensure effective sealing, selection of sealing materials, sealing element is mainly based on the working environment, working medium such as temperature, pressure, use and movement etc.. The basic requirements for sealing materials are as follows:I have certain mechanical properties such as tensile strength, elongation, etc.;
- Q: What is the maximum resistance to the seal in the hydraulic system currently being produced?
- With the ring to 30MPa, if you use a triangular sealing structure (similar plug root) can be used in 70MPa.
