Description
Technical field
The utility model relates to pump field, particularly a kind of submerged pump.
Background technique
Shown in Fig. 1 and Fig. 2, existing submerged pump comprises pump seat 1, the pump housing 2, motor component 3, connecting base 4 and pump cover 5, the sealing fastening structure of submerged pump pump cover 5, usually need hole on pump cover end face of flange, during assembling, need install fastening screw trip bolt additional can fastening pump cover; This structural requirement designer is when design connecting base structure, and need design and pump cover separately to assemble the sphere structure of fastening screw trip bolt, this connecting base structure, when casting, because structural walls is uneven thicker than crossing, easily produces the casting defects such as cold shut, pore, sand holes; The O-ring seals Position Design of this pump cover structure is at the end face of pump cover, and when assembling, the problem that O-ring seals is sheared easily occurs, and assembling difficulty is higher, not easily assembles.
Model utility content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, easy to assembly, a kind of submerged pump of good seal performance.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of submerged pump, comprise pump seat, the pump housing, motor component, connecting base and pump cover, described connecting base is connected with the pump housing, described connecting base and the interconnective end of the pump housing all offer tapped hole, tapped hole on described connecting base end runs through whole connecting base end, during installation, both are connected by bolt; The side that described connecting base end and pump housing end are positioned at the pump housing is equipped with the seam coordinated with pump cover mounting end, and these two seams form the mounting groove for settling pump cover mounting end, and during installation, described pump cover mounting end is fastened in mounting groove; The upper surface of described pump cover mounting end is provided with O type circle groove, is provided with O RunddichtringO in described O type circle groove.
In an embodiment of the present utility model, the height of described mounting groove is identical with pump cover mounting end thickness.
In an embodiment of the present utility model, the upper surface of the O RunddichtringO after described installation is higher than the upper surface of pump cover mounting end.
By technique scheme, the beneficial effects of the utility model are:
The utility model pump cover does not need to hole on pump cover end face of flange when mounted, does not need to install fastening screw trip bolt additional yet and gets final product fastening pump cover; The utility model changes the sealing station of O-ring seals, makes assembling more convenient, and does not affect the sealability in connecting base chamber; Both met the sealing fastening requirements of submerged pump, and turn improved the efficiency of assembling of submerged pump, and structure is simple, greatly reduces the casting defect of foundry goods, is conducive to cost-saving.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in Fig. 3 and Fig. 4, the utility model discloses a kind of submerged pump, comprise pump seat 10, the pump housing 20, motor component 30, connecting base 40 and pump cover 50, connecting base 40 is connected with the pump housing 20, connecting base 40 and the interconnective end of the pump housing 20 all offer tapped hole 60, and this two tapped hole 60 is symmetrical arranged, the tapped hole 60 on connecting base end 41 runs through whole connecting base end 41, during installation, connecting base end 41 and pump housing end 21 link together through two tapped holes by bolt 70; The side that connecting base end 41 and pump housing end 21 are positioned at the pump housing is equipped with the seam coordinated with pump cover mounting end, pump cover end face of flange does not need boring; These two seams form the mounting groove 80 for settling pump cover mounting end, and the height of mounting groove 80 is identical with pump cover mounting end 51 thickness, and it is convenient to the insertion of pump cover mounting end 51, and during installation, pump cover mounting end 51 is fastened in mounting groove 80; The upper surface of pump cover mounting end 51 is provided with O type circle groove 51a, and be provided with O RunddichtringO 90 in O type circle groove, the upper surface of the O RunddichtringO after installation, higher than the upper surface of pump cover mounting end, which raises sealability.
O RunddichtringO 90, when assembling, is first contained in the O type circle groove 51a of pump cover, then is fastened in mounting groove 80 by pump cover mounting end 51 by the utility model in advance, then pump cover 50 and O-ring seals 90 are compressed and put in place by the bolt 70 be connected with the pump housing 20 by connecting base 40; This structure had both met the sealing fastening requirements of submerged pump pump cover, also can improve efficiency of assembling while the seal request meeting connecting base chamber.The design of the pump cover that sealing fastening structure requires, connecting base structure is more simple, greatly reduces the casting defect of foundry goods, improves the up-to-standard rate of foundry goods, cost-saving.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
