Abstract

The invention discloses a cartridge type mechanical seal device, which includes a mechanical shaft, a moving ring and a static ring, the moving ring includes a first moving ring and a second moving ring, and the static ring includes a first static ring and a second static ring; It also includes a moving ring shaft casing, a gland, and a mechanical seal fixing flange; the moving ring shaft casing includes a first moving ring shaft casing and a second moving ring shaft casing, and the first moving ring shaft casing is arranged on the machine Between the shaft and the moving ring and the static ring, two moving rings are arranged at both ends, the static ring is arranged between the two moving rings, the shaft sleeve sleeve of the second moving ring is adjacent to the second moving ring and is arranged on the second A moving ring shaft casing outside; the first static ring and the second static ring are sleeved with glands with water inlets and water outlets, and the glands are connected to the fixed flange of the machine seal; the glands, moving rings, A sealed cavity is formed between the static ring and the moving ring shaft sleeve. The invention has the advantages of compact structure, simple installation, convenient use, good dynamic balance and durability, and can be used for sealing in solid-liquid-powder-particle mixture working conditions, and has strong durability in sealing under pressure.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a cartridge-type mechanical seal device applicable to the working condition of solid-liquid-powder particle mixture, convenient for installation and replacement, and good in pressurized seal durability. Background technique [0002] Mechanical seal (mechanical seal) refers to 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 prevent fluid leakage. device. [0003] A mechanical seal is a shaft seal device for a rotating machine. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the ...
