Self-pressure boosting system for double-end mechanical seal

Abstract

The invention discloses a self-pressure boosting system for a double-end mechanical seal. The self-pressure boosting system comprises a mechanical seal device, a balancing tank and a reaction tank, wherein the upper part of the balancing tank is connected with a sealing liquid inlet of a sealing cavity of the mechanical seal device through a pipeline, and the lower part of the balancing tank is connected with an in-kettle gas communication pipe of the reaction kettle through a pipeline; a piston and a piston rod are arranged in the balancing tank and are matched with each other; the piston is sealed with the cylinder wall of the balancing tank through an O-shaped seal ring; the piston rod slides along the axial direction; a spring is arranged on the piston rod. The self-pressure boosting system is simple in structure; the upper part of the balancing tank is connected with the sealing cavity through the pipeline, and the lower part of the balancing tank is communicated with the reaction kettle through the pipeline, so that the pressure in the kettle is transferred to the sealing cavity through the piston in the balancing tank; the self-pressure boosting system is suitable for occasions where mediums in the kettle cannot be mixed with sealing liquid.

Description

technical field [0001] The invention relates to the field of sealing, in particular to a double-face mechanical seal self-pressure boosting system. Background technique [0002] Leakage problems are ubiquitous in modern industry. Leakage will not only cause energy waste, material loss, and environmental pollution, but also cause fires and explosions, directly endangering personal safety and bringing huge economic losses. For occasions where the medium in the kettle cannot be mixed with the sealing liquid, if the seal is not good, there may be dangers of corrosion, flammability, explosion, and toxicity. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a double-end mechanical seal self-pressure boosting system, which is suitable for occasions where the medium in the kettle cannot be mixed with the sealing liquid. [0004] The technical scheme that solves the above-mentioned te...
