Abstract
The utility model provides an inner bush-replaceable double metal cylinder jacket used for a mud pump. The utility model is characterized in that the inner liner and an outer bush are in taper fit. When the inner liner is worn out and scrape, a housing screw on a gland is demounted, the inner liner can be replaced with a special tool, dispensing with scrapping the outer bush. The utility model has the advantages of low labor intensity, processing expenses saving and steel product saving.
Description
The utility model relates to a kind of Metallic cylinder, particularly a kind of interchangeable bi-metal liner of liner that is used for slurry pump.
Cylinder sleeve is the vitals on the drilling mud pump.Slurry pump carries out work by piston to-and-fro motion in cylinder sleeve bore.Cylinder sleeve bore is through the wearing and tearing of certain hour, and cylinder sleeve just needs to change, and working life is not long.
For prolong the working life of cylinder sleeve as far as possible, common way is to adopt the bi-metal liner that is assembled by liner and overcoat two-part.Adopt interference fit between the liner of this cylinder sleeve and the overcoat, and stick with glue.Because liner is to pack into after the integral quenching in the overcoat, its endoporus hardness and wear resistance are all relatively good.But, in use, if the liner wearing and tearing then need whole cylinder sleeve all changed.Site operation personnel's labor intensity is big when changing cylinder sleeve, also intact overcoat is scrapped together after the liner wearing and tearing, has wasted steel.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and a kind of the bi-metal liner of changing the cylinder sleeve liner is provided.
Task of the present utility model is to finish by following approach: adopt taper fit between the outer wall of cylinder sleeve liner and the inwall of overcoat, the interior edge face of gland contacts with liner, be connected by housing screw between gland and the overcoat, it is fastening that liner and overcoat are cooperated.
Embodiment during the utility model is incited somebody to action in conjunction with the accompanying drawings is described in further detail.
Fig. 1 is the sectional drawing of a kind of concrete structure of the utility model.
With reference to Fig. 1, the interchangeable bi-metal liner of this liner comprises an overcoat (1), and a liner (2) is 0.5 °～3 ° taper fit between the outer wall of the inwall of overcoat (1) and liner (2).A gland (3) is pressed on the big end end face of liner (2).On the big end end face of overcoat (1) and gland (3) 2～10 equally distributed screw holes are arranged respectively, 2～10 housing screws (4) couple together overcoat (1) and gland (3), and liner (2) is pressed in the internal taper hole of overcoat (1).After liner (2) wearing and tearing are scrapped, the housing screw (4) on the gland (3) is laid down, taken out liner (2), change the new liner of same size again, and need not change overcoat (1) with special tool.
The utility model has following advantage compared with prior art: under service life constant prerequisite, only change the cylinder sleeve liner, and simple and convenient, alleviated the labour intensity the when site operation personnel loads and unloads. Because overcoat can use continuously, has not only saved the processing charges of overcoat, also can save a large amount of steel.
Claims (3)
1, a kind of drilling mud pump bi-metal liner that is used for is made up of overcoat [1], liner [2], it is characterized in that having a gland [3] to be connected with liner [2].
2, according to the described bi-metal liner of claim 1, it is characterized in that on gland (3) and the overcoat (1) 2～10 equally distributed screw holes being arranged, connect by 2～10 screws (4) between gland (3) and the overcoat (1).
3, according to claim 1 or the described bi-metal liner of claim 2, the inwall that it is characterized in that the outer wall of liner (2) and overcoat (1) is 0.5 °～3 ° a taper fit.
