Mechanical seal is a sealing device used in mechanical equipment, especially in rotating equipment (such as pumps, compressors, mixers, etc.) to prevent liquid or gas leakage. It is mainly composed of static rings, dynamic rings, springs, sealing surfaces, auxiliary seals and other parts. The working principle is to use the friction between the sealing surfaces to achieve the sealing function. Common types of mechanical seals include: Single-end mechanical seal: the most common type, suitable for most common working conditions. Double-end mechanical seal: used for high temperature, high pressure or toxic and dangerous media working conditions. Balanced type and unbalanced type: according to the change of pressure between the dynamic and static ring surfaces, it is divided into balanced type and unbalanced type. Mechanical seals have the following significant features: 1. Good anti-leakage performance The main function of mechanical seals is to prevent the leakage of liquids, gases and other media in the equipment. It achieves efficient sealing effect through high-precision contact of the sealing surface and the pressure of the spring, which can effectively avoid environmental pollution and product loss. 2. Wide range of applications Mechanical seals are widely used in the sealing of various liquids and gases, such as petroleum, chemical, food, pharmaceutical and other industries, and are suitable for various rotating equipment such as water pumps, centrifugal pumps, compressors, etc.
