Description
Technical field:
The utility model relates to slag stock pump field, specifically is a kind of slag stock pump labyrinth bush.
Background technique:
The sealing of slag stock pump always is a problem that makes the researcher have a headache, and along with the expansion of slag stock pump using scope, this problem is just more outstanding.Because the solid particle that the slag stock pump is carried is increasing, the harmfulness of liquid is more and more serious, the more common silt of these materials to the corrosion of axle and sealing and wearing and tearing all can more serious shortening sealing working life, and in a single day sealing lost efficacy, and leaked just directly to affect the normal operation of pump or even operator's personal safety.The sealing problem that solves the slag stock pump will be understood its seal form.
The axle envelope of slag stock pump mainly contains following a few class: packing seal, mechanical seal, float ring seal, other sealing etc.The utility model has designed the radial and axial rectangular-shaped circular groove of multiple tracks, and tortuous gap is to medium repeatedly throttling and the damping function that plays, and viscous flow boundary layer etc. " labyrinth effect " that factor produced, causes the gap to be blocked in the gap in, realizes sealing.
The model utility content:
The purpose of this utility model provides a kind of slag stock pump labyrinth bush, has solved the difficult problem of slag stock pump axle envelope effectively, and good sealing effect, long service life.
The technical solution of the utility model is as follows:
Slag stock pump labyrinth bush, comprise the labyrinth bush body, described labyrinth bush body is the pipe shape, it is characterized in that: described labyrinth bush body outer wall middle part is provided with multiple tracks annular radial rectangle groove one, the outer wall end is provided with ring-type taper platform, ring-type taper platform left side is provided with axial ring-type rectangle groove two, and ring-type taper platform outer wall is provided with multiple tracks annular radial rectangle groove three.
Described slag stock pump labyrinth bush is characterized in that: described labyrinth bush bulk material is HT200.
The utility model has the advantages that:
The utility model novel structure, good sealing effect, rigidity and strength character are good, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Slag stock pump labyrinth bush, comprise labyrinth bush body 1, labyrinth bush body 1 is the pipe shape, labyrinth bush body 1 outer wall middle part is provided with multiple tracks annular radial rectangle groove 1, the outer wall end is provided with ring-type taper platform 3, ring-type taper platform 3 left sides are provided with axial ring-type rectangle groove 24, and ring-type taper platform 4 outer walls are provided with annular radial rectangle groove 35, and labyrinth bush body 1 material is HT200.
