Abstract
The utility model disclose a pump body of a lining plastic transmission pump, which comprises a metal pump body and a lining plastic layer compounded on an overflowing face of the metal pump body. The pump body is characterized in that the inner wall of the metal pump body is provided with a dovetail groove and a threaded hole, and the lining plastic layer is embedded into the dovetail groove and the threaded hole. The pump body of the lining plastic transmission pump is simple and reasonable in structure, firm and reliable in adhesion between a casing of the pump body and the lining plastic layer, stable in running of the limiting transmission pump and long in service life.
Description
Technical field
The utility model relates to a kind of pump housing, and particularly a kind of lining is moulded the pump housing of drive pump.
Background technique
For being applicable to, drive pump carries any acidity, alkaline corrosion property medium; Usually be lined with one deck plastic lining layer at metal pump intracoelomic cavity overcurrent wall; Yet the metal pump housing and plastic lining layer bonding are insecure; Make that in use both occur separating, and plastic lining layer is yielding, these have all shortened the working life of pump.
The model utility content
The utility model technical problem to be solved is, overcomes the defective that existing technology exists, and provides a kind of metal pump housing to combine more firm lining to mould the pump housing of drive pump with plastic lining layer.
The utility model addresses the above problem the technological scheme that is adopted: this lining is moulded the pump housing of drive pump; Comprise the metal pump housing and the plastic lining layer that is compounded in metal pump housing flow-passing surface; It is characterized in that: the internal face of the described metal pump housing has dovetail groove and tapped hole, and described plastic lining layer embeds dovetail groove and tapped hole.
Be welded with chain link fence on the interior inclined-plane of the described metal pump housing of the utility model, described plastic lining layer parcel chain link fence.
The material of the described plastic lining layer of the utility model is fluoroplastic.
The utility model compared with prior art has the following advantages: the running that simple and reasonable, pump housing shell and plastic lining layer bonding are solid and reliable, lining is moulded drive pump more steadily, improved working life.
Description of drawings
Fig. 1 is the utility model embodiment pump housing structure schematic representation.
Fig. 2 is the right TV structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1, present embodiment comprises metal pump housing I and the plastic lining layer that is compounded in metal pump housing I flow-passing surface, and the internal face of metal pump housing I has dovetail groove 1 and tapped hole 2, and plastic lining layer embeds dovetail groove 1 and tapped hole 2.Be welded with chain link fence 4 on the interior inclined-plane 3 of metal pump housing I, described plastic lining layer parcel chain link fence 3.The material of plastic lining layer is fluoroplastic.
Present embodiment is simple and reasonable, pump housing shell and plastic lining layer bonding is solid and reliable, the running of plastic lined pump more steadily, improved working life.
Though the utility model with embodiment openly as above; But it is not in order to limit the protection domain of the utility model; Any technician who is familiar with this technology, change and the retouching in design that does not break away from the utility model and scope, done all should belong to the protection domain of the utility model.
Claims (3)
