Construction projects without large-scale mechanical equipment, while many construction machinery in the manufacturing process are inseparable from each type of seal products, especially machinery products to deal with liquids, engineering skills in mechanical seal purchasing methods.
1, based on speed, using Rotary or static and hydrodynamic or non-contact type;
2, according to the seal chamber pressure to determine seal structure with balanced or unbalanced, such as single or double face;
3, according to the space of installation seals determined using spring or spring or wave spring, built-in or installed type;
4, according to temperature and fluid properties, determining friction and auxiliary materials, and proper selection of lubrication, cleaning, insulation, mechanical seal cooling loop protection systems.
