Q: Looked at some of your questions about the sealing ring, I think you are a master in this fieldHave a question to ask about the sealing ring on the mechanical supporting industry inside, there is a reasonable use of time (under normal working conditions), also found a lot of norms, did not seem to have the answer I want. I wonder if you know any specifications or official statements.: To answer this question, you generally, the quality of Taiwan's sealing ring must be very good, in a normal working pressure, the temperature is appropriate, a service life of the sealing ring may be decades, there may be hundreds of years, and so you say, as long as the machine is not a problem, then the sealing ring is not removed, you can continue to use, as long as the machine is out of the question, to open the maintenance, so the sealing ring will need to be replaced. So why do those machines manufacturers buy a lot of seals?

Q: It's three yuan ethylene propylene sealing stripEPDM rubber sealing strip production enterprises are relatively concentrated or relatively large scale: Aluminum Alloy seal doors and windows, steel doors and windows, glass curtain wall seal sealant, container door seal and a door sponge rubber sealing strip, sealing tape, self-adhesive frozen door sealing strip, the doors of the glass slide, door trim, sponge sealing strips and retaining of the glass doors, glass windshield seal, fire seal flame retardant, pipe, tube, silicone tube, winding hose, water pipe, air pipe and oil pipe, automotive rubber seal, EPDM seal, with flexible sealing strip, sponge foaming adhesive tape, sealing tape, foam tape

Q: What is the function of the seal?: The seal can be divided into rotary shaft oil seal, seal, dust ring, piston and piston rod seal and so on, a lot of daily life to sound like dust and waterproof, oil seal for many industrial equipment, such as waterproof and dustproof.

Q: What are the basic parameters of the seal on the diagram?: Temperature: -40/+200Material: NBR/PTFE FKMMedium: hydraulic oil, flame retardant liquid, water and gas

Q: Why can't polyurethane seal be used as hydraulic oil with water glycol?: Water ethylene glycol is dissolved by water (35~55%) and ethylene glycol, and is added with water-soluble thickening agent, antioxidant, rust inhibitor and anti foaming agent, etc., or propylene glycol or other polymer can be used instead of ethylene glycol

Q: What are the differences between silicone rubber and butyl rubber in the use of water seals for home improvement?Which is better for tightness, durability and heat resistance?Looked at each answer, still confused, at present most of the water seals are used Ding Qing, even if very small seals, why?: Nitrile main resistance to oil, I currently contact mainly with ethylene propylene waterproofing is the majority!

Q: What are the rubber seals made of?: Rubber, with plastic, fiber and called the three major synthetic materials, is the only high flexibility and excellent elasticity of high polymer materials. The first characteristic of rubber is that the modulus of elasticity is very small, and the elongation is very high. Second, it has excellent breathability and resistance to a wide variety of chemical and electrical insulation. Some special synthetic rubber has good oil resistance and temperature resistance, resistance to fatty oil, lubricating oil, hydraulic oil, fuel oil and solvent oil swelling; cold can be low to - 60 DEG C to 80 DEG C, heat up to 180 DEG C to 350 C + +. Rubber is also resistant to a variety of bending and bending deformation, because the hysteresis loss is small. The third characteristic of rubber is that it can be used in combination with many materials, blending and compounding so as to obtain good comprehensive properties.

Q: The material of the seal must be compatible with the medium in contact with it. Why? What is compatibility? Thank you: Therefore, the compatibility between them requires simple understanding that they do not react to each other in order to maintain their respective characteristics.

Q: Excuse me, what's the material for the general piston ring?: 2. porous copper impregnated fluorine plastic metal bearing, it can be used normally under high temperature, high pressure, dry friction and vacuum;3. PTFE fiber bearing PTFE fiber and glass fiber or other fiber blended fabric made of bearing lining for low speed, high load;4. fill PTFE piston ring, guide ring, machine tool guide and Bridge slider

Q: How to choose the sealing ring according to the shaft?: General hardness is chosen according to pressure, low pressure with low hardness material, high hardness with high pressure. According to the load type can be divided into static seal and dynamic seal. According to the sealing use, can be divided into hole seal, shaft seal and rotating shaft seal
