Movable ring assembly sealing device

Abstract

The invention discloses a movable ring assembly sealing device. The movable ring assembly sealing device is composed of a movable ring assembly and a shaft sleeve. The movable ring assembly is composed of a movable ring, a first steel ball, a sealing gasket, a pressing ring, a wave spring, a wave spring seat, a shaft retainer ring and a second steel ball. A shaft sleeve step is arranged at one endof the shaft sleeve. A first steel ball socket is arranged on the right side of the shaft sleeve step, a spring clamping groove is formed in the other end of the shaft sleeve, and a second steel ballsocket is arranged on the left side of the spring clamping groove. The first steel ball is arranged in the first steel ball socket. The movable ring abuts against the shaft sleeve step. The sealing gasket is pressed into an inner hole of the movable ring and pressed by the pressing ring. The wave spring abuts against the pressing ring. The second steel ball is arranged in the second steel ball socket. The wave spring seat abuts against the wave spring. The shaft retainer ring is clamped in the spring clamping groove and is integrated with the spring clamping groove. The movable ring sealing assembly is small in axial size and convenient to install, the flatness and perpendicularity of the end face of the movable ring are high, and the load around the end face is uniform.

Description

technical field [0001] The invention belongs to the field of mechanical seals, in particular to a sealing device for a moving ring assembly. Background technique [0002] The mechanical seal device is a sealing device for centrifugal pumps, positive displacement pumps and shafts of various rotating equipment. The mechanical seal is a precision component, which requires high installation accuracy. The axial distance of the conventional mechanical seal is long, and it is not easy to install in the pump with a small installation space. During the installation, the problem of improper installation is likely to occur, which seriously affects the use of the mechanical seal device. When the installation error is large, the service life of the mechanical seal will be shortened, and even the mechanical seal will be damaged. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a moving ring component sealing device with s...
