Hebei boxed o-ring crankshaft

Hebei box seal ring crankshaft, due to long-term production accumulation, our company has now issued a variety of PTFE oil seal mold (mainly compressor oil seal) up to thousands of teflon stainless steel skeleton oil seal. When the working pressure of medium is very high, several v-shaped rings can be combined and used. The pressure ring exerts a pressure on the v-shaped ring, and the v-shaped rings are combined into a whole. The pressure can be adjusted according to the medium pressure. Even if the leakage medium through the Channel v Ring, the pressure will be greatly reduced, through the Second Channel v Ring Lip, the pressure is reduced once, so that the internal pressure will be lost, leakage is stopped.

Because the hydrolytic resistance of ether bond is much stronger than that of carboxylic Ester Bond (about 510 times) , EU is not easy to hydrolyze, and the content of rubber (NBR) and hydrogenation is lower than that of CAN. Polyurethane o-ring Pu o-ring high pressure o-ring NR natural rubber o-ring: good wear resistance, elasticity, tensile strength and elongation. But in the air easy to aging, become sticky in the heat, in mineral oil or gasoline easy expansion and dissolution, alkali-resistant but not strong acid. Suitable for use in hydroxide liquids such as car brake oil and ethanol. Silicone rubber has the characteristics of high temperature, corrosion resistance, good sealing and long service life, so most enterprises use it as sealing ring material, only generally the lower end of the product is the use of silicone foam strips.

Due to the large compression deformation of the synthetic rubber seal, its static friction resistance is especially large, usually more than twice its dynamic friction resistance. Such a large static friction resistance in some low-pressure rubber transmission system is bound to cause low-pressure creeping and operating difficulties and other undesirable phenomena, which is why the self-sealing pressure-type rubber seal is very small and used as a moving seal alone. PTFE STAINLESS STEEL FRAME OIL SEAL PRINCIPLE: PTFE OIL SEAL LIP is pulled into a trumpet shape when it is processed. Because PTFE has the ability of memory contraction after being drawn, the friction heat produced in the work causes the lip lip lip to contract continuously, so the help of spring is not needed, it will cling to the shaft, so that there is no gap between it and the surface of the shaft, but also to compensate for wear. Material selection error, see is simple is actually more complex, not simply based on the use of materials, but also to learn to combine the use of the environment, for example, one customer does not like the use of o ring, because this o ring is very easy to break. When we examined the replacement samples, we found cracks on the surface of the samples, which resembled ozone aging. We also asked about the o ring environment, found that there are a lot of mechanical equipment and Electric Motors. O-ring crankshaft in Changsha box. For high hardness rubber, process safety is also important. But just use it! The vulcanized rubber compound has low elongation, slow vulcanization rate and poor thermal tearing property. In order to overcome this shortcoming, at home and abroad has been adopted! The method of-sulfur yellow-accelerator compound vulcanization system aims at increasing vulcanization rate, improving hot tearing property and increasing elongation. It is reported that under normal circumstances, the temperature is certain, the decomposition rate is also certain, will not increase the curing rate because of the increase in dosage. And cost-effective import skeleton oil seals how to choose when we buy imported skeleton oil seals, we must have the basic knowledge of identifying fake and inferior products, this will help us to be able to buy and cost-effective oil seals. If the rubber products aging, will reduce the life of rubber products, or even failure. The factors that affect the aging of rubber products are heat source, sunlight, ultraviolet ray, oxygen, ozone, chemical corrosion and so on. So, how can we prevent the aging of rubber and rubber products? Here mentioned the anti-aging agent, is in the rubber product formula to add a special ingredient, slow down and prevent its aging. In order to avoid ozone-induced aging, we generally use a combination of amine and sulfur compounds and paraffin.
