Abstract
The utility model relates to a kind of split type Piping Centrifugal Pumps, comprise the pump housing, impeller, pump shaft, motor, machine envelope, bearing, motor is fixedly connected with the pump housing by adpting flange, adpting flange and the pump housing are tightly connected, fitting machine envelope and bearing between pump shaft and adpting flange, the lower end of pump shaft is fixedly connected with impeller by leaf cap, it is mainly pump shaft upper end fixed installation coupling, this coupling is cylindrical structure, cylindrical lower end surface is fixedly connected with pump shaft upper end, cylindrical body center is shaped with and the moving circular hole coordinating of motor shaft, cylindrical body circular-hole internal-wall is provided with flat key along cylindrical body centerline direction, the keyway of this flat key and motor shaft end cooperatively interacts.By coupling, be connected with motor shaft plug-in type, Pump and Electromotor can be exchanged supporting, user can independently buy pump and motor supports the use, and has the advantages such as easy to use, maintenance cost is low.
Description
Technical field
The utility model belongs to pump field, particularly about a kind of centrifugal pump.
Background technique
Centrifugal pump is comprised of the pump housing, pump cover, pump shaft, impeller, machine envelope, motor, and motor shaft extends in the pump housing and is fixedly connected with impeller, and motor and pump are an overall structure, when pump shaft damages, will change together with machine shaft simultaneously, and maintenance cost is high.In order to solve the problem that the maintenance of integrated type centrifugal pump bothers, maintenance cost is high, split type centrifugal pump obtains generally and promotes.But the pump shaft of existing split type centrifugal pump is connected by coupling with motor shaft, need on motor shaft and pump shaft, fixedly mount respectively intermeshing clutch-plate, can pump is separated with motor during maintenance.Because motor shaft is installed clutch-plate, motor and pump will connect into an integral body and sell, and Pump and Electromotor is for corresponding supporting one by one, can not wildcard, to user's use, make troubles.
Summary of the invention
The purpose of this utility model is the shortcoming existing for prior art, the split type Piping Centrifugal Pumps of provide a kind of motor to exchange, easy to use, maintenance cost is low.
The technical solution of the utility model comprises the pump housing, impeller, pump shaft, motor, machine envelope, bearing, motor is fixedly connected with the pump housing by adpting flange, adpting flange and the pump housing are tightly connected, fitting machine envelope and bearing between pump shaft and adpting flange, the lower end of pump shaft is fixedly connected with impeller by leaf cap, it is mainly pump shaft upper end fixed installation coupling, this coupling is cylindrical structure, cylindrical lower end surface is fixedly connected with pump shaft upper end, cylindrical body center is shaped with and the moving circular hole coordinating of motor shaft, cylindrical body circular-hole internal-wall is provided with flat key along cylindrical body centerline direction, the keyway of this flat key and motor shaft end cooperatively interacts.
In above technological scheme, on adpting flange, be shaped with bearing chamber, pump shaft upper end is provided with the boss with brearing bore interference fit, and bearing is fitted in bearing chamber by coupling lower end surface.
The utility model has the advantages that pump shaft upper end fixed installation coupling, this coupling is connected with motor shaft plug-in type, Pump and Electromotor can be exchanged supporting, and user can independently buy pump and motor supports the use, easy to use, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As the split type Piping Centrifugal Pumps of Fig. 1, comprise the pump housing 1, impeller 2, pump shaft 4, motor 8, machine envelope 6, bearing 7, motor 8 is fixedly connected with the pump housing 1 by adpting flange 5, adpting flange 5 is tightly connected with the pump housing 1, the lower end surface of adpting flange 5 and the pump housing 1 are tightly connected and are equivalent to the effect of pump cover, fitting machine envelope 6 and bearing 7 between pump shaft 4 and adpting flange 5, the lower end of pump shaft 4 is fixedly connected with impeller 2 by leaf cap 3, pump shaft 4 upper end fixed installation coupling 9, this coupling 9 is cylindrical structure, cylindrical lower end surface is fixedly connected with pump shaft 4 upper ends, cylindrical body center is shaped with and the moving circular hole coordinating of motor shaft, cylindrical body circular-hole internal-wall is provided with flat key along cylindrical body centerline direction, the keyway of this flat key and motor shaft end cooperatively interacts, flat key inserts the keyway on motor shaft, making motor and pump realize plug-in type is connected.Flat key can be integrally manufactured with cylindrical body, also can adopt the keyway interference fit on independently flat key and cylindrical body inner hole wall to form.The pump housing can adopt vertical structure, also can adopt horizontal type structure.
On adpting flange 5, be shaped with bearing chamber, pump shaft 4 upper ends are provided with the boss with bearing 7 endoporus interference fit, and bearing 7 is fitted in bearing chamber by coupling 9 lower end surfaces.
