Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0024] The present invention provides an extendable and rotatable mechanical sealing device, which ensures that the shaft sleeve can slide effectively in the shaft sleeve transmission sleeve and can ensure the sealing performance, avoiding poor sealing caused by the movement of the shaft sleeve. During use, Once the shaft sleeve is damaged, it can be replaced directly without disassembling the whole set of seals, which effectively reduces maintenance time and cost and improves production efficiency.

[0025] The present invention will be described in further detail below in conjunction with examples and specific implementation methods.

[0026] Such as figure 1 Shown: a mechanical seal device that can be extended and rotated, including: shaft sleeve 1, shaft sleeve transmissi...

Abstract

The invention discloses a mechanical sealing device with extending and rotating functions. The mechanical sealing device comprises a shaft sleeve, a shaft sleeve transmission sleeve, a moving ring transmission sleeve, at least one moving ring, a static ring and a sealing box body, wherein the static ring are the same with the moving ring in number, the shaft sleeve is a hollow shaft sleeve, the shaft sleeve is fixedly arranged on a main shaft, the shaft sleeve is installed in the shaft sleeve transmission sleeve, the moving ring transmission sleeve is arranged on the shaft sleeve transmission sleeve in a sleeve mode, the moving ring transmission sleeve is fixed on the moving ring in a sleeve mode, the moving ring is movably installed on the static ring, the static ring is fixed on the sealing box body, and the sealing box body is arranged on the outer side of the static ring. According to the mechanical sealing device, it is guaranteed that the shaft sleeve can effectively slide in the shaft sleeve transmission sleeve, the sealing performance can be ensured, the poor sealing caused by the fact that the shaft sleeve moves is avoided, in the using process, once the shaft sleeve is damaged, the shaft sleeve can be directly replaced without detaching the whole seal, so that the maintenance time and cost are effectively reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an extendable and rotatable mechanical seal device. Background technique [0002] 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 medium in the equipment leaks outward through this gap, so there must be a shaft sealing device to prevent leakage. [0003] During the working process of the mechanical sealing device, due to the stroke of the shaft, the sealing performance of the sealing device needs to be improved. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention proposes an extendable and rotatable mechanical seal device, which can ensure that the shaft ...
