Mechanical seal selection method

2020 - the choice of the mechanical seal method 9 - 26 now, both in the valve industry and engineering industry, the existence of the mechanical seal is indispensable, it also brought the rise of the mechanical seal manufacturers. No container in modern machinery manufacturing machinery is a kind of large construction machinery products. Many engineering machinery in the manufacturing process is inseparable from the various types of sealing products, especially mechanical products processing liquid. Buy engineering mechanical seals should pay attention to? 1, according to the working speed, determination by chemical industry printing and dyeing machinery seal rotating or stationary type, the hydrodynamic pressure type or non-contact type; 2, according to the sealed cavity pressure, determine the seal structure is balanced or unbalanced type, single or double face, etc. ; 3, according to the installation of sealed space effectively, determine the multiple mechanical seal factory spring or single spring or waveform spring, built in or outside the container type; 4, according to the temperature, and fluid properties, determine the friction pair and auxiliary sealing material, as well as the correct selection of lubrication, flushing, insulation, cooling and other mechanical seal protection system etc.
