The invention discloses a manufacturing method of a small spring double-end-face mechanical sealing device. The small spring double-end-face mechanical sealing device comprises a spring seat, first springs, second springs, a moving ring, a static ring and a gland, wherein the plurality of first springs abut against the static ring, and the plurality of second springs abut against the moving ring,so that the moving ring and the static ring are tightly attached together; when one of the second springs or the first springs fails, the moving ring and the static ring can be tightly attached through the rest of the first springs and the second springs, and therefore the sealing effect of the mechanical sealing device is guaranteed; and even if the first springs or the second springs fail completely, the moving ring and the static ring can still be tightly attached under the action of the second springs or the first springs, so that the sealing effect of the mechanical sealing device is guaranteed, and the problem that the sealing effect of the mechanical sealing device is affected due to failure of a single spring is solved.
Description
technical field [0001] The invention relates to the technical field of mechanical sealing devices, in particular to a manufacturing method of a small spring double-end mechanical sealing device. Background technique [0002] Mechanical seal refers to a device that prevents fluid leakage by keeping at least one pair of end faces perpendicular to the rotation axis under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of auxiliary seals to keep fit and slide relatively. [0003] Most of the traditional mechanical seal devices use a single spring to hold the moving ring against the static ring, and achieve the corresponding seal through the frictional cooperation between the static ring and the moving ring. The ring cannot fit closely with the static ring, thus affecting the sealing effect of the mechanical seal device. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide ...
