What is the main attack direction of mechanical seal materials?

What is the main attack direction of mechanical seal materials? The functional effect of mechanical seals is an overall technical level issue. It seems that the main point of the production of mechanical seals is to deal with the problem of soft materials in the conflict: compared with foreign countries, there is a greater distance than double-end mechanical seals, mainly because of fewer types. Poor and quality. The main direction of attack should be: ① Carbon graphite impregnation technology, which should be able to impregnate various resins, metals, ceramics, mechanical shaft seals and glass in the seal factory, especially impregnation of various metals and siliconized graphite, etc.; ②Addition and improvement For the types and quality of auxiliary seals, the mechanical seals should be the dynamic ring seals of composite materials, such as PTFE-coated rubber, etc.; ③ Pay attention to and develop auxiliary systems and equipment for mechanical seals, and respond according to different conditions. Equipped with auxiliary measures or devices that do not use mechanical seals for pumps. Others should also pay attention to and carry out the development and research of elastic components. For example, the stress of the asymmetric bellows tends to be uniform and there is no stress concentration. Its natural frequency is far away from the pump speed, reducing the possibility of vibration and resonance, and sealing Improved capacity and increased flexibility of the bellows.
