Abstract
The utility model relates to a novel pump body of an impurity pump. The pump body comprises a pump body formed by casting; lugs are respectively cast at two end faces of the pump body along the circumference of a water inlet and the circumference of an impeller inlet, and the lugs are provided with bolt clamping grooves formed by casting. The pump body with large size is composed of an upper pump casing and a lower pump casing formed by casting; edge ears with casting holes are cast at the edges of the upper pump casing and the lower pump casing; the corresponding edge ears arranged on the edges of the upper pump casing and the lower pump casing are tightly fixed by bolts; a sealing strip is clamped between the interior end faces of the upper pump casing and the lower pump casing. The novel pump body of an impurity pump has the connecting structure of the lugs and the bolt clamping grooves of a one-step casting forming, so after the pump body is formed by casting, machining technology is not needed, and the connection and the fixation of the pump body, a pump cover and a filter cover. Because the pump body has no need of the machining technology, the pump body is directly formed by casting wear resistant materials with high hardness, and overcomes the contradiction of the hardness of the casting materials and the machining need of the pump body in the prior art. The pump body has reasonable structure, simple manufacturing technology and low cost.
Description
Technical field
The utility model relates to the transh pump pump housing, is specially a kind of novel transh pump pump housing.
Background technique
The impeller that drives by rotating shaft by motor in the pump cover that transh pump comprises the pump housing, be connected and fixed with pump housing top, the filter cap that is connected and fixed with pump housing bottom and the pump housing.The pump housing is normally cast and is formed.Because the operating conditions of transh pump is more abominable, the pump housing need have higher hardness and wear resistance, but the linkage structure that again need processing on the pump housing be connected and fixed with pump cover, filter cap (or flange), as connecting screw, processing seam etc.The pump housing is as selecting the casting material of high hardness for use, though improved the wear resistance of the pump housing, but bring difficulty to machining.For overcoming hardness and mach contradiction, can adopt heat treatment process to adjust the hardness of pump housing machining front and back, but make complex manufacturing, increased cost of production.Still do not have a kind ofly have one-step casting moulding linkage structure at present, have high hardness and high-wearing feature and need not the mach pump housing.
Summary of the invention
The utility model solves the contradiction that exists between existing transh pump pump housing material hardness, wear resistance and the need process for machining, provides a kind of and has one-step casting moulding linkage structure, has high hardness and high-wearing feature and need not the novel transh pump pump housing that process for machining can be installed and used.
The utility model is to adopt following technological scheme to realize: the novel transh pump pump housing, comprise the pump housing of casting, and be cast with projection in pump housing both ends of the surface respectively along water intake circumference and impeller inlet circumference, the bolt draw-in groove of casting is arranged on the projection.
Owing to had the linkage structure of the one-step casting moulding of projection, bolt draw-in groove, need not process for machining behind the pump housing casting can realization and being connected and fixed of pump cover, filter cap (or flange) (bolt card that is connected and fixed between pump cover, filter cap and the pump housing is fixed in interior the getting final product of bolt draw-in groove on the projection) on this novel transh pump pump housing.Owing to need not process for machining, the pump housing can directly be cast with the high-abrasive material of high hardness and form, and has overcome the pump housing casting material hardness of prior art existence and the contradiction between the need machining.This pump body structure is reasonable, manufacturing process is simple, and cost is low.

Embodiment
The novel transh pump pump housing comprises the pump housing 2 of casting, is cast with projection 8,9 in pump housing both ends of the surface respectively along water intake circumference and impeller inlet circumference, and the bolt draw-in groove 5 of casting is arranged on the projection 8,9.Need not process for machining behind this pump housing casting can install and use.The bolt card that is connected and fixed between pump cover 1, filter cap 4 and the pump housing 2 is fixed in the bolt draw-in groove 5 on the projection and gets final product (seeing accompanying drawing 1).
The pump housing size of large-scale transh pump is bigger, for ease of casting processing, at this moment, the pump housing 2 is made of the last pump case 6 of casting, following pump case 7, last pump case, down the pump case edge is cast with the limit of blowhole ear 10 is arranged on it, corresponding sides ear on last pump case and the following pump case edge accompanies Stamping Steel Ribbon 12 with bolton (realizing being connected and fixed between the upper and lower pump case with this) between the interior edge face of last pump case and following pump case.The pump housing of this structure is used under the larger-size situation of the pump housing.
The cross section of Stamping Steel Ribbon 12 correspondingly, has half slot 13 on the corresponding position of last pump case and following pump case interior edge face for go out rectangle to the both sides extension on the axis of middle part circle.Cylindrical body on the Stamping Steel Ribbon 12 is pressed in the corresponding half slot that is stuck on the upper and lower pump case interior edge face.Adopt this odd-shaped cross section Stamping Steel Ribbon, help improving the sealing between the upper and lower pump case.
Be cast with on the housing both ends of the surface " well " font stiffening rib 11.To improve pump housing intensity.
