Mechanical sealing device of enamel reactor

You may know that the reactor has single face mechanical seal and double face mechanical seal. What’s the difference between them? Let’s introduce the difference between them.

1. The single face seal has the advantages of simple structure, easy manufacture and installation. It is generally used under the conditions of good lubricity of the medium itself and allowing slight leakage. It is not suitable for use when the medium is toxic, flammable, explosive and has strict requirements for leakage.

2. Double face seal includes axial double face seal and radial double face seal (axial: direction parallel to the axis, radial: direction perpendicular to the axis). The radial double face seal structure is more compact than the axial double face seal. Double face seal is applicable to the medium with poor lubricity, toxic, flammable, explosive, volatile, abrasive particles and gas; The axial double end face seal has a face-to-face or back-to-back structure. During operation, it is necessary to introduce a sealing liquid 0.05 ~ 0.15Mpa higher than the medium pressure between the two pairs of end faces to improve the lubrication and cooling conditions between the end faces, and isolate the medium from the outside, which may realize “zero leakage” of the medium.

Well, that’s all for the small series of single end mechanical seal and double end mechanical seal. If you have any questions, please consult our company.
