The invention discloses a manufacturing method of a small spring double-end mechanical seal device, which comprises a spring seat, a first spring, a second spring, a moving ring, a static ring and a gland, and a plurality of first springs are connected to the static ring. A plurality of the second springs resist the moving ring, so that the static ring and the static ring are tightly fitted together, when one of the second springs or the first When the spring fails, the moving ring and the static ring can rely on the rest of the first spring and the second spring to closely fit, thereby ensuring the sealing effect of the mechanical seal device; even if the first spring or the All the second springs fail, and the moving ring and the static ring can still fit tightly under the action of the second spring or the first spring, so as to ensure the sealing effect of the mechanical seal device and solve the problem of The failure of a single spring affects the sealing effect of the mechanical seal device.
Description
technical field [0001] The invention relates to the technical field of mechanical sealing devices, in particular to a method for manufacturing a small spring double-face mechanical sealing device. Background technique [0002] A mechanical seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and the cooperation of the auxiliary seal to keep fit and slide relative to each other. [0003] Most of the traditional mechanical seal devices use a single spring to hold the moving ring against the static ring, and realize the corresponding seal through the friction fit 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. Contents of the invention [0004] The purpose of the present invention is to p...
