Description
Technical field
The present invention relates to mechanical engineering pump class technical field, specifically a kind of vertical single stage Piping Centrifugal Pumps.
Background technology
Currently, the vertical pipeline mounted pump of China's application, its structure does not have an independent electrical motor supporting structure, pump cover support directly and
Motor connects disk connection, while impeller axle and motor shaft are an axle, middle nothing has shaft coupling transition to connect.In pump group maintenance or more
When changing spare part, motor and pump cover need to integrally be pulled down, maintenance trouble, when improper use causes axle to damage, the replacement cycle it is long and
Have a strong impact on manufacturing schedule.
The content of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model to be to provide one kind and carry free-standing structure, turn
The cantilever design vertical single stage Piping Centrifugal Pumps that son can be taken out.
To achieve these goals, the technical solution adopted in the utility model is：The vertical single stage Piping Centrifugal Pumps is main
By motor, angular contact ball bearing, deep groove ball bearing, pump cover, impeller nut, the pump housing, pump shaft, impeller, electric machine support, bearing body and
Shaft coupling is constituted；Motor is connected by independent electric machine support with the pump housing, and motor shaft and pump shaft are scratched by with middle extension
Property diaphragm coupling connection；There are angular contact ball bearing, the deep groove ball bearing of support pump shaft in bearing body, impeller will by impeller nut
Impeller is fixed on the tail end of pump shaft, and pump shaft, impeller, pump cover, bearing body constitute one and be integrally attached on the pump housing.
The beneficial effects of the utility model are：Because independent electric machine support is connected with the pump housing, rotor is set to be not subject to and pass
Pass quality load and the vibration of motor；Rotor can be extracted out from pump head by the extension in the middle of dismounting couplers, maintenance side
Just；Angular contact ball bearing balancing axial thrust, deep groove ball bearing balance radial load, eliminates conventional pipeline pump axial force and is held by motor
The defect of load, operates pump more steady.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model vertical single stage Piping Centrifugal Pumps.
In figure：1. motor, 2. angular contact ball bearing, 3. deep groove ball bearing, 6. pump cover, 7. impeller nut, the 8. pump housing, 10.
Impeller, 12. electric machine supports, 13. bearing bodies, 14. shaft couplings.
Specific embodiment：
In the accompanying drawings, the utility model vertical single stage Piping Centrifugal Pumps, the pump is main by motor, angular contact ball bearing, depth
Ditch ball bearing, pump cover, impeller nut, the pump housing, pump shaft, impeller, electric machine support, bearing body and shaft coupling are constituted；Motor 1 is by only
Vertical electric machine support 12 is connected with the pump housing 8, rotor is not subject to and transmit quality load and the vibration of motor；Motor shaft and pump shaft
Connected by with middle extension flexible membrane shaft coupling 14, by the extension in the middle of dismounting couplers can by rotor from
Pump head is extracted out, easy to maintenance；There are angular contact ball bearing 2, the deep groove ball bearing 3 of support pump shaft, angular contact ball axle in bearing body 13
Balancing axial thrust is held, deep groove ball bearing balance radial load eliminates the defect that conventional pipeline pump axial force is undertaken by motor, makes pump
Operating is more steady；Impeller is fixed on impeller 10 tail end of pump shaft, pump shaft, impeller 10, pump cover 6, bearing body by impeller nut 7
13 constitute one is integrally attached on the pump housing 8, forms the cantilever design that rotor can be taken out, and is easy to maintenance.
