Q:Reasons affecting the tightness of cylinder
1, piston and cylinder clearance2, piston ring end clearance3 、 piston ring backlash4 cylinder cylindricity5, valve tightness
Q:What are the seals that are resistant to 500 degrees of high temperature?Airtight chamber gas temperature up to 500 degrees, what are the appropriate seals available? Thank you
Airtight container seals are static seal, you can use the "flexible graphite" material made of seals, capable of more than 1000 degrees high temperature. (dynamic seal does not apply).
Q:How should the piston rings for piston wear be chosen? What is the national standard?
Cylinder piston due to long-term reciprocating motion, reciprocating piston seals should be used to require wear-resistant, oil corrosion resistance, hardness is best at about 85 degrees.The choice of sealing ring material is of great importance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.
Q:What kind of equipment do you need to open a small seal factory?
Raw materials, if you want their own rubber, it is very troublesome, at least you have to glue formula, and then you are small-scale, raw materials are sold by the ton, you buy less, the cost will be high.
Q:What are the criteria for choosing the sealing ring type of hydraulic cylinders?

Noise reduction and decompression of the seat, and therefore used for flashing and other industrial and mining, the drawback is that the media can not be used for dirty areas.V- ball and eccentric rotary valve can be used in slurry and other impurities containing medium.
Q:About the service life of hydraulic cylinder sealing ring
24 hours, non-stop use, in addition to the temperature, there are friction, so generally 3 to 5 months, personally, there is no specific definition, depending on the environment, the use of frequency, temperature. Medium. Etc..
Q:Differences and connections between fasteners and seals
The fastener is basically metal material and plays a fixed role in the place where the equipment needs to be connected.
Q:What are the differences between polyurethane TPU and CPU in cylinder seals?
Is a new type of polymeric material between rubber and plastic, in practical application, as a rubber product, because CPU has excellent abrasion resistance (the elastomer), casting polyurethane elastomer (CPU) is also called a thermosetting elastomer, at room temperature into liquid solid characteristics after processing, so CPU is often used for casting processing, such as casters, mining, refining, textile, printing machine roller, the finished product in wear resistance strong.
