What is the main direction of mechanical seal energy raw materials?
The functional effect of mechanical seals is a problem of the overall technical level. It seems that the main point of the production of mechanical seals is to deal with the problem of soft materials in conflict pairs: compared with foreign countries, there is still a large distance between double-end mechanical seals, mainly due to less variety. Poor quality castle. The main direction of attack should be: ①The impregnation technology of carbon graphite should be able to impregnate various resins, metals, ceramics, mechanical shaft seals and glass, etc., especially to impregnate various metals and silicide graphite, etc.; ②Add and improve The type and quality of auxiliary seals are mainly based on the dynamic ring seals of composite materials, such as polytetrafluoroethylene-coated rubber, etc.; Equipped with the same auxiliary measures or equipment as the mechanical seal used in the pump. In addition, it is necessary to pay attention to and carry out the development and research of elastic components. For example, the stress of asymmetric bellows tends to be uniform and there is no stress concentration. Its natural frequency is far away from the speed of the pump, which reduces the possibility of vibration resonance and makes the seal The ability is improved, and the elasticity of the bellows is enhanced.
