Abstract

An integrated bellows mechanical seal device for a pump comprises a bellows type moving ring assembly (1), a static ring assembly (2), a shaft sleeve (3), a press cover (4) and a stopping clamping matching mechanism (5) arranged between the outer side of the press cover and the shaft sleeve. The integrated bellows mechanical seal device is characterized in that a fixed seat (18) is arranged at the rear end of a moving ring tailstock (12). A seal groove (13), a seal ring (14), a check ring (15), a clamping ring (17) and an anti-rotating pin screw (31) are arranged, and the moving ring assembly (1) is connected with the shaft sleeve (3). A connecting protruded ring (32), a seam allowance seal groove (33), a seal ring (34), a press ring (35) and a fastening screw (38) are arranged at the front end of the shaft sleeve (3), and the shaft sleeve (3) is connected with a shaft. The integrated bellows mechanical seal device is good in structure, overcomes the problem of deformation of the shaft sleeve (3) caused by the fastening screw and is compact in radial dimensions, convenient to install and reliable to use.

Description

technical field [0001] The invention relates to a mechanical sealing device, in particular to an integrated bellows mechanical sealing device. Background technique [0002] The mechanical seal device includes a moving ring assembly and a static ring assembly mechanism. The moving ring or the static ring with a bellows is used as a compensation ring, and the moving ring with a bellows is generally used as a compensation ring. The moving ring assembly and the static ring assembly of the mechanical seal device are installed on the shaft and the gland respectively, and the moving ring assembly installed with the shaft is directly fixed and installed on the shaft, or the moving ring assembly is fixedly installed with the shaft sleeve, and the shaft sleeve Fixed fit with the shaft. [0003] In order to achieve the assembly form between the moving ring component, the static ring component and the gland, the structure with a shaft sleeve is adopted. The moving ring component and th...
