Abstract
The utility model relates to a connecting base structure for a small diving sewage pump, in particular to the improvement of the connecting base structure. The connecting base for the small diving sewage pump comprises a connecting base and is characterized in that the connecting base is conical; three reinforcing ribs uniformly distributed along the circumference are arranged on the inner lateral surface of the connecting base; a bearing chamber is arranged in the middle of the top of the connecting base; a seam allowance is arranged on the bottom of the connecting base; the upper ends of the reinforcing ribs are connected with a bearing chamber; the lower ends of the reinforcing ribs are connected with the seam allowance; a lug is arranged at the inner side of a connecting plate; the end surface of the lug is aligned to the lower end surface of the connecting base so as to provide convenience for processing; a threaded through hole is formed in the middle of the lug; a groove is formed above the bearing chamber; and a mechanical sealing groove is formed below the bearing chamber. The connecting base for the small diving sewage pump has the advantages that: a plurality of components can be saved, and the amount of finish and the assembly procedure are reduced, so that the work efficiency is improved and the cost is saved.
Description
Technical field
The utility model relates to a kind of connecting base structure that is used for small-sized proof submersible sand discharging pump, particularly to the improvement of connecting base structure.
Background technique
In proof submersible sand discharging pump, connecting base is used for laying bearing and mechanical seal.Shown in accompanying drawing 1 in the existing structure: connecting base has upper and lower two seams 111,112; Because seam plays positioning action; So requirement on machining accuracy is very high; Owing to there are two seams, between casing and the connecting base, all will adorn O-ring seals between connecting base and the pump cover and prevent water inlet in the water pump; Mechanical seal is contained in the bearing gland, and it is fastening that bearing gland and connecting base are connected through screw, between bearing gland and the connecting base O-ring seals is housed; Casing and connecting base also will link together through screw during assembling.Because small-sized proof submersible sand discharging pump is all produced in enormous quantities, so, just can reduce amount of finish, simplify linkage editor, thereby can reduce cost of production if can simplify the structure of certain part.Therefore demand urgently the connecting base of existing small-sized proof submersible sand discharging pump is improved.
Summary of the invention
The purpose of the utility model is that the connecting base that solves the middle-size and small-size proof submersible sand discharging pump of existing technology adopts two existing the problems referred to above of seam, and a kind of connecting base of novel small-sized proof submersible sand discharging pump simple in structure is provided.A kind of connecting base that is used for small-sized proof submersible sand discharging pump of the utility model design comprises connecting base, it is characterized in that: connecting base is for conical; The connecting base inner side surface is provided with three along the equally distributed stiffening rib of circumference, is provided with bearing bore at the crown center of connecting base, is provided with seam in the bottom of connecting base; The connection bearing chamber, upper end of stiffening rib, the lower end connects seam, and there is a lug connecting plate inboard; The end face of lug is equal with the connecting base lower end surface, is convenient to processing like this, is processed with tapped through hole in the middle of the lug; The top of bearing bore is processed with groove, and the below is processed with the mechanical seal groove.The utility model has the advantages that and to save numerous parts, reduced amount of finish and assembly process, thereby improved working efficiency, practiced thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and instance the utility model is elaborated.
Embodiment
Among Fig. 3,1 is connecting base, and 11 is rotor; 12 is stator, and 13 is axle, and 14 is circlip for hole; 15 are mechanical seal, and 16 is pump cover, and the utility model has removed upper and lower two seams in the existing structure; Be designed to have only a seam, this has not only alleviated the weight of connecting base, has also reduced amount of finish; Connecting plate is done coning; Can make full use of the inner space; The wall thickness reduction of connecting plate increases by three along the equally distributed stiffening rib of circumference to 4-5mm, and stiffening rib couples together seam, connecting plate and bearing bore to gain in strength; Stiffening rib thickness is 6mm, has so not only alleviated weight and has also guaranteed intensity; There is a lug connecting plate inboard, and the end face of lug is equal with the connecting base lower end surface, is convenient to processing like this, in an operation, just can the end face and the processing of connecting base lower end surface of lug be put in place, is processed with tapped through hole in the middle of the lug and is used for installing the profit probe; The top of bearing bore is processed with groove; Groove is used for installing circlip for hole; Circlip for hole is used for fixing bearing, and the below of bearing bore is processed with the mechanical seal groove, and the mechanical seal groove is used for installing mechanical seal; So just can save these three parts of bearing gland, O-ring seals and screw in the existing structure, simplify assembly process; The utility model directly links together casing and pump cover when assembling with screw 5, connecting base is clipped between casing and the pump cover, leans on seam 5 location, and O-ring seals 4 is housed between casing and the pump cover, has so just saved screw and the O-ring seals in the existing structure.So adopt after the utility model structure, can save numerous parts, reduce amount of finish and assembly process, thereby improved working efficiency, practiced thrift cost.
