The tightness of the O-ring seal is very important:
It can be said that in our lives, the presence of O-ring seals is relatively high, as small as refrigerators, washing machines, faucets, rice cookers, and even automobiles, ships, and large mechanical equipment can find the shadow of O-ring seals. It is said that once the sealing ring fails, then these equipment may not work well, so it is very important to ensure the sealing performance of the O-ring.
What are the factors that can cause the O-ring seal to lose its sealing effect?
1. Improper design: The manufacturer did not pass good calculations and tests when designing the O-ring seal, such as the lack of a correct estimate of the pressure-bearing capacity of the O-ring seal, and the contact stress distribution on the sealing surface. Unscientific, inaccurate groove size planning, etc.
2. The quality is not good enough: usually, the manufacturer will conduct multiple performance tests and random checks on the product qualification rate before production. Because O-rings are mass-produced products, it is inevitable that there are defective products, so when encountering defective products, it is easy to fail during use.
3, wrong material selection: At present, there are many raw materials for the production of O-rings, and products produced by different materials are different in performance and use. When purchasing, if you choose casually without considering the material, it may cause leakage after time.
4. Incorrect use: A good quality O-ring seal will fail immediately if it is used incorrectly.
In order to ensure the sealing effect of O-rings, we need to purchase products from regular manufacturers, choose appropriate models and specifications, and pay attention to correct use.
