Abstract
The utility model relates to a sealing device of printing and dyeing pump, its structure is to increase a pump axle sleeve on the pump shaft, is equipped with the spring in it with mechanical seal on the pump axle sleeve, when the pump shaft drove the high-speed operation of pump axle sleeve, produced the power of turning compression spring, supported the sealing member to play sealed effect. The structure is simple and compact, and the installation is convenient.
Description
The utility model relates to a kind of seal arrangement of Dyeing printing pump.
In the prior art, the mechanical seal of Dyeing printing pump is that the rotating seat that utilizes machine to seal up is screwed on axle sleeve drive machine envelope work, and when being transferred when being corrosive medium, the rotating seat of machine envelope very easily is corroded, thereby machine envelope sealability is descended greatly, and seal ring damages easily.
The purpose of this invention is to provide a kind of seal arrangement that overcomes the Dyeing printing pump of above-mentioned shortcoming.
The present invention is achieved in that installs a cover seal arrangement additional on common Dyeing printing pump, it is characterized in that, on the pump shaft of former Dyeing printing pump, increase an axle sleeve supporting with it, axle sleeve is the part interference fit with axle, an axle sleeve and an end are provided with the axle sleeve shoulder of a projection, and mechanical seal of peripheral hardware is provided with a spring in mechanical seal, its spring one end is located on the axle sleeve shoulder of axle sleeve, and an end props up seal ring.
The advantage that this cover seal arrangement is installed is: 1, owing to the rotating seat of not use machine envelope, it is undesired to reduce the pump work that causes owing to corrosion, makes maintenance, installs or change seal ring very convenient; 2, owing to increased axle sleeve, on axle sleeve, be provided with seal arrangement, in mechanical seal, rely on the drive of axle, with spring action when proper functioning to axle sleeve, spring is with the forward running of axle sleeve, spring is revolved tighter and tighter, pushes down mechanical seal, makes it reach the effect of sealing, for preventing the mechanical seal transfer, be provided with a stop pin.
Fig. 1 has provided the inner main structural representation of Dyeing printing pump.
Below in conjunction with accompanying drawing 1 specific embodiment of the utility model is described:
On pump shaft (1), be provided with the axle sleeve (2) of a part of interference fit, have a shaft shoulder on the axle sleeve (2), a seal arrangement (3) is housed on axle sleeve.Be provided with a spring (4) in these devices, an end of spring is located on the axle sleeve shoulder, and the other end props up mechanical seal (3).When pump shaft (1) high-speed motion, drive pump shaft cover (2) motion, the bullet that is produced is done, can push down mechanical seal (3) thus play the effect of sealing, mechanical seal is by stop pin (5) locking.
Claims (3)
1, a kind of Dyeing printing pump of being made up of corrosion-resistant material shell, impeller, pump shaft, moving ball seat is characterized in that it also has an axle sleeve supporting with it (2), is provided with the axle sleeve shoulder of a projection at the skin of axle sleeve.
2, Dyeing printing pump according to claim 1 is characterized in that; Be provided with spring in the described mechanical seal.
3, Dyeing printing pump according to claim 1 is characterized in that described pressure spring one end is located on the axle sleeve shoulder, and an end is located at mechanical seal.
