Like other products, China mechanical seals can be designed and calculated, but some parameters cannot fully reflect the real sealing conditions due to the limitation of testing technology and mechanism research level. Therefore, in a sense, the mechanical seal is a relatively experimental technology. So some people think that the seal design is only regarded as an experimental technology, and in fact it cannot be as reliable as calculating the strength of bridges or sliding bearings. The difficulty lies in the lack of systematic information on sealing characteristics. For this reason, the test work of the mechanical seal shall be carried out in the following cases.
1. Newly designed products are subject to technical verification.
2. Products that have been mass-produced should be regularly tested for the stability of the amount.
3. In some specific working conditions outside the scope of application of the product or if there are special requirements for sealing, tests should be carried out in order to evaluate the adaptability of the product.
4. The research on the mechanism of mechanical seals, through experimental research and theoretical analysis, guides the development of new structures and new materials, and improves the technical level of mechanical seals.
During the test, the test technique used is very important. Only by using a variety of advanced testing techniques can an accurate assessment of a product be made. Test technology is an important basis for the production of first-class products.
