Abstract
The utility model discloses a novel steel lining graphite impeller, which comprises an impeller and a back cap. The impeller is composed of an impeller body (1) and a graphite anticorrosive layer (2) cast on the surface of the impeller body, wherein the blade (6) of the impeller body (1) is provided therein with honeycombed round holes, the impeller body (1) is provided with a shaft hole (10), the shaft hole is provided therein with a key slot (8), the end surface of the graphite anticorrosive layer (2) is provided with a first seal groove (9), the back cap is composed of a cap cover (3) and a bushing (4), the bushing (4) is embedded in the cap cover, and provided with inner round screw thread, the cap cover (3) is a semisphere-shaped graphite body, and the end surface of the cap cover (3) is provided with a first seal groove (7). The novel steel lining graphite impeller can ensure the corrosion resistance and the strength of the graphite impeller, also ensures the bonding strength of the graphite anticorrosive layer on the blade, and can be repaired after being damaged for reutilization. The novel steel lining graphite impeller reduces maintenance cost and has higher economic value.
Description
Technical field
The utility model relates to graphite pump impeller in the chemical pump, specifically is a kind of steel lining graphite impeller.
Background technique
Existing used graphite pump or the graphite axial-flow pump of chemical industry, its impeller are generally and adopt machining graphite to form, the graphite material deficiency be intensity low, be prone to crisp, wear no resistance; Graphite impeller is in operation blade can fracture damage; Make it that pump operation vibration is big, efficient is low, cause rate of fault high, working life is low; And can not repair the graphite impeller of damaging can only integral replacing, and maintenance cost is high.
Summary of the invention
In order to overcome deficiency of the prior art, the utility model provides a kind of steel lining graphite impeller, and this graphite impeller has not only guaranteed the corrosion resistance and the intensity of graphite impeller, and renewable reparation is used.
The technological scheme of the utility model is: a kind of steel lining graphite impeller; It is made up of impeller and back of the body cap, and it is characterized in that: said impeller constitutes by impeller body and at impeller body surface casting graphite anticorrosion layer, and the blade of impeller body is provided with cellular circular hole; Blade is helical or volute shape; Impeller body is provided with axis hole, has keyway on the axis hole, and graphite anticorrosion layer end face is provided with the seal groove II; Said back of the body cap is made up of cap and lining, and lining is embedded in the cap, and lining is provided with interior round thread, and cap is hemispherical graphite body, and the cap end face is provided with seal groove Ι.
Said impeller body, lining material are stainless steel.
The principle of the utility model is: this steel lining graphite impeller is that back of the body cap is made up of the graphite body that studs with the stainless steel lining, can guarantee the corrosion resistance and the intensity of graphite impeller at its stainless steel impeller surface cast graphite anticorrosion layer; On blade, be provided with cellular circular hole, can guarantee to be cast in graphite anticorrosion layer adhesive bond power on the blade, damage renewable reparation and use, reduced maintenance cost.
The utility model has the advantages that to have overcome the high deficiency of graphite impeller rate of fault in service in the existing technology, can guarantee its corrosion resistance and intensity; Solved simultaneously graphite impeller can not repair can only integral replacing problem, reduced maintenance cost, have bigger use value and an economic value.
