1. In accordance with the body seal chamber pressure, determine the sealing structure using balanced or unbalanced type, single face or double face like. The operating speed is determined using a rotary or static ISG65-250 mechanical seals, fluid dynamic pressure type non-contact type. 3. The temperature and fluid properties to determine friction and auxiliary sealing materials, as well as the correct choice of lubrication, wash, heat, cooling and other mechanical seal circulation protection system. 4. The effective installation space sealed determine the use of multiple springs or single spring or wave spring, built-in or externally mounted. Sealing ring is the ring and stationary ring collectively (below), are the most important elements of mechanical seals. Sealing ring largely determines the mechanical seal performance and life, therefore, it made a number of demands. 1. Have sufficient strength and rigidity. Under operating conditions (such as pressure, temperature and sliding speed etc.) are not damaged, deformed mechanical seal should be as small as possible, while still maintaining sealing working conditions fluctuate. 2. Seals should have sufficient hardness and corrosion resistance, in order to ensure a satisfactory service life under operating conditions. 3. Seal ring should have good thermal shock resistance. To this end, it requires materials with high thermal conductivity and a small linear expansion coefficient, and will not crack when subjected to thermal shock. 4. Seal ring should match the smaller friction coefficient and good self-lubricating ISG200-400 mechanical seal, seal ring material and sealing fluid also has good wettability. Work in the event of a short period of dry friction, does not damage the seal faces. 5. Seal ring should be simple, symmetrical and priorities with the overall structure. It may also be combined (such as cassette type) sealing ring ISG65-200 mechanical seal, to avoid spraying the end face sealing structure. 6. Sealing ring easier to manufacture, installation and maintenance to be convenient, the price is low.
