- Q: What rubber kind of rubber does the brake seal of the car use?
- Because he is the first production. He asked me. I told him that the first, customer is the name of 15 years ago called, because at that time the brake is so called castor oil, brake oil, castor oil, brake is sensitive enough, the driver should step down to stop with great force, so come now the
- Q: Replacement seals, but it does not feel like a O ring, ask this solenoid valve seals what is the name, specifications how to express?
- Cage or sleeve is considered large differential pressure or high pressure or large caliber valve, is now more and more common, and can add a variety of
- Q: What's the function of the sealing ring?
- Mechanical seal work should pay attention to the problem1, installation notesA, take great care to avoid installation errors in installation(1) to tighten the gland should be aligned in the coupling bolts should be uniform, to prevent the end cap oblique, with feeler check, the error is less than 0.05 mm.(2) clearance check the gland and the shaft or shaft diameter (i.e. concentricity), around to evenly, not more than 0.01 mm check with the feeler the tolerance.B, spring compression amount should be carried out according to regulations, not allowed to have too large or too small phenomenon, requiring 2 millimeters of error. Excessive assembly increases the face to face pressure, and the other speeds end wear. Too little will cause less pressure than sealing.C, the ring should be installed to ensure flexible movement on the axis, the moving ring pressure to the spring, it should automatically bounce back.
- 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: How are ceramic and metal sealed joint?
- If it is static sealAxial, O ring or flat gasket can be used; radial O ring can be used.If it is dynamic seal, in addition to radial seal, but also consider whether the need for axial dust ring.The end face seal has a special sealing ring, and the lip is contacted with the ceramic surface.For reciprocating motion, a combination of O rings or other cross sections can be used.
- Q: The seal of the front end of the cylinder and the cylinder, "O" ring, why has it been serrated for some time?,
- It should be considered that the gap between the two mounting surfaces of the 0 type ring is too large.It is recommended to reduce the fit clearance or increase the retaining ring.
- Q: How should the piston rings for piston wear be chosen? What is the national standard?
- Two, HNBR hydrogenated nitrile rubber sealing ring: with excellent corrosion resistance, tear resistance and compression deformation characteristics, ozone resistance, sun resistance, weather resistance better. Better abrasion resistance than nbr. The utility model is suitable for washing machines, automobile engine systems and refrigeration systems using new environmental protection refrigerant R134a. Not recommended for use in alcohols, esters, or aromatic solutions. The general use temperature range is -40~150 degrees centigrade.Three, SIL silicone rubber sealing ring: with excellent heat resistance, cold resistance, ozone resistance, atmospheric aging resistance. Has good insulation performance. But the tensile strength is inferior to that of ordinary rubber and has no oil resistance. Applicable to household appliances, such as electric water heaters, electric irons, microwave ovens, etc.. The utility model is also suitable for various articles which have contact with human bodies, such as a kettle, a water dispenser, etc.. Not recommended for use in most concentrated solvents, oils, concentrated acids, and sodium hydroxide. The general use temperature range is -55~250 degrees centigrade.
- Q: The difference between the oil seal ring and the gasket
- But in the sealing field, oil seal is used for rotating the skeleton oil seal, and non professional fields, such as some used seal factory engineers, said the oil seal is used to seal oil seal, including static seal and reciprocating rotary oil seal oil seal and seal oil seal.
- Q: Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?
- Silicone rubber is much better than ordinary rubber in heat resistance. It can be used almost always at 150 degrees without performance changes. It can be used continuously for 10000 hours at 200 degrees, and can be used for a period of time at 350 degrees. The utility model is widely used for occasions requiring heat resistance, a thermos bottle sealing ring and a heat-resistant handle of a pressure cooker ring.
- Q: What is the maximum resistance to the seal in the hydraulic system currently being produced?
- Therefore, in order to improve the sealing capacity, not only rely on seals, good structure is also very important. You say, if the light takes into consideration the seal, there is no problem with the regular 50MPa (usually around 30).
