Embodiment Construction

[0012] The self-cleaning mechanical seal cavity structure of the present invention is composed of a lotion inlet 1, a body cone 2, a structural gland 3, a mechanical seal 4, a shaft 5 and a lotion outlet 6, and is characterized in that the mechanical seal 4 It is installed on the shaft 5 , and is integrally fitted in the body cone 2 , and fixed on the body cone 2 through the structural gland 3 . Wherein the sealing chamber of the body cone 2 is processed into a cone structure, the inner diameter of the sealing chamber is small, and the outer diameter is large, forming a frustum of cone structure. The washing liquid inlet 1 tangentially enters the inner outer diameter of the body cone 2, and its tangential direction is consistent with the rotation direction of the mechanical seal dynamic ring. The washing liquid outlet 6 is tangent to the outer diameter of the outer large end of the body cone 2, and its tangential direction is consistent with the rotation direction of the mecha...

Abstract

The invention relates to a self-cleaning mechanical seal chamber structure, which consists of a lotion inlet (1), a body vertebral body (2), a structural gland (3), a mechanical seal device (4), a shaft (5), and a lotion outlet ( 6) Composition. The sealing cavity makes the overall installation and disassembly of the seal easy to maintain and repair, and the constraint is reduced. The sealing performance is good; the solid particles existing in the prior art, such as the abrasive wear of the sealing end face caused by the pumping of the sealing end face, can be washed away at any time, and there is no end face friction and wear. , improve sealing stability, solve problems such as short service life; flushing makes the end face temperature rise low, energy consumption is small, sealing and stability are good, so this kind of sealing has good reliability and reduces maintenance and repair costs.

Description

technical field [0001] The invention relates to a self-cleaning mechanical seal cavity structure, which belongs to the technical field of mechanical equipment manufacturing. Background technique [0002] At present, petrochemical high-temperature and high-viscosity medium pumps are mainly used in the transportation of process media in propane plant asphalt pumps, atmospheric and vacuum distillation, catalytic cracking, hydrogenation and coking plants in the petrochemical refining and chemical industry. Its operating conditions are usually in the state of high temperature and high viscosity, and the transported substances are oil and asphalt medium. Due to the high temperature of the medium, it will cause cracking and fusion of the mechanism, resulting in polymerization reaction, resulting in polymerization product particles, resulting in friction on the end face of the mechanical seal. Wear and tear failure, and then lead to material leakage and cause fire, explosion and oth...
