Embodiment Construction

[0008] In the axially split pump body sealing device shown in the figure, the pump body 1 is provided with a sealing ring 2, and the outer circumference of the sealing ring 2 is provided with an anti-movement semicircle protrusion 3, and the pump body 1 is provided with a semicircle groove to prevent The movable semicircular protrusion 3 is embedded in the semicircular groove, and the semicircular protrusion 3 cooperates with the semicircular groove to prevent the rotation and axial movement of the sealing ring 2. The semicircular protrusion 3 is not easy to be damaged, and the frequency of damage to the sealing ring is low. It saves time and does not affect production.

Abstract

The invention discloses an axially split type pump body sealing device and relates to a sealing device. A sealing ring is arranged in a pump body; anti-movement semicircular protrusions are arranged at the periphery of the sealing ring; a semicircular groove is formed on the pump body; and the semicircular protrusions are embedded into the semicircular groove. The anti-movement semicircular protrusions are arranged at the periphery of the sealing ring, the semicircular groove is formed on the pump body, and the semicircular protrusions are embedded into the semicircular groove to match the semicircular groove, so that the sealing ring is prevented from rotating and axially moving, the semicircular protrusions are difficult to damage, the damage frequency of the sealing ring is low, the pump is prevented from being detached for maintenance, the labor and time are saved, the production is not influenced, and the axially split type pump body sealing device is suitable for axially split type pump body sealing.

Description

technical field [0001] The invention relates to a sealing device, in particular to an axially split pump body sealing device. Background technique [0002] As we know, the existing axially split pump body sealing device is provided with a seal ring in the pump body, pin holes are provided on both sides of the seal ring, anti-rotation pins are arranged in the pin holes, and the anti-rotation pins fix the seal ring On the pump body, the sealing ring is prevented from rotating and moving axially. This kind of axially split pump body sealing device has pin holes on both sides of the seal ring, and anti-rotation pins are arranged in the pin holes. The anti-rotation pins fix the seal ring on the pump body to prevent the seal ring from rotating and axially Movement, the anti-rotation pin is often broken due to large radial and axial shear forces, the seal ring and the impeller are damaged by friction, the damage frequency of the seal ring is high, and the maintenance of the pump i...
