Seal machinery is one of the basic mechanical precision components, structure iscomplex, is a key component of all kinds of pumps, reaction kettle, turbine compressor,the submersible motor and other equipment. The sealing performance and service lifedepends on many factors, such as selection, the precision of the machine, the correctinstallation and use.

A, selection method

Mechanical seal according to the working conditions and the medium properties, high temperature resistant, low temperature resistant mechanical seal, high pressure resistance, corrosion resistance and mechanical seal, light hydrocarbon resistance ofgranules medium mechanical seal and adapt to easy vaporization of the mechanicalseal, should according to the different use of different structural type and materialselection of mechanical seal.

Selection of major parameters: seal chamber pressure
