Description
Technical field
The utility model relates to a kind of pump connecting cover structure of water pump, belong to centrifugal water pump manufacturing technology field.
Background technology
The operation principle of centrifugal water pump may be summarized to be：Motor driven impeller is rotated at a high speed, and the effect by centrifugal force is thrown
Go out liquid.Concrete structure is：Impeller is housed on the axle of direct current generator, when motor rotates at a high speed, impeller rotates at a high speed, so as to
Pressure differential is produced in the radial direction of impeller.Impeller central site pressure is small, and marginal portion pressure is big, and liquid is inhaled from water inlet
Enter, pressure is produced in edge part, the pressure causes liquid to be spilled over from delivery port, forms current.
But there is also distinct disadvantage for common centrifugal DC water pump：Complicated, volume is big, and heat dispersion is poor, mainly
Reason is the unreasonable structure of the pump housing, therefore carries out rational modification to pump body structure, is advantageous to the whole centrifugal water efficiency of pump
Raising.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides one kind in prior art basis
It is being improved, simple in construction, easy to install, be advantageous to the pump connecting cover for the water pump that the overall centrifugal water efficiency of pump improves
Structure.
To achieve these goals, the utility model provides following technical scheme：A kind of pump connecting cover structure of water pump, it
The pump housing of receiving centrifuge blade rotation cavity, the described pump housing are internally formed after being connected including side opening and with pump cover
Opposite side banding side, central axial in its edge sealing are provided with the middle bearing block for carrying central shaft hole, the edge sealing outside of the pump housing
It is provided with outside upper, bearing block and is installed the ring seat in the motor of axial outer gibbosity；Neighbouring rotation cavity is set on the bearing block
There are a radiating and insulated cavity；The edge sealing side outer end of the pump housing is provided with a horn-like external outlet pipe.
As preferred：End set of the bearing block central shaft hole positioned at inner radiating and insulated cavity side has at least one
Road supplies the seal groove that sealing ring is embedded, and the motor installation end that outside is located in bearing block central shaft hole is provided with for dynamic sealing machine
The shaft type annular seal space that structure loads；Radiating and the reinforcement of radial arrangement are additionally provided with the pump housing outer wall of bearing block side；
Described horn-like external outlet pipe is to be gradually transitions radially outlet from axial sides by arc pore, forms an arc mistake
Cross the simultaneously diminishing horn-like external outlet pipe of bore.
The utility model is the improvement carried out in prior art basis, have it is simple in construction, easy to install, favorably
In the overall centrifugal water efficiency of pump improves the features such as.

The utility model is described in detail below in conjunction with accompanying drawing：Fig. 1, shown in 2, one kind described in the utility model
The pump connecting cover structure of water pump, it includes side opening 1 and internally forms receiving centrifuge blade rotation after being connected with pump cover
Turn the pump housing 3 of cavity 2, the described opposite side banding side 4 of the pump housing 3, center is carried in the central axial centre that is provided with of its edge sealing 4
The bearing block 6 of axis hole 5, the upper, outside of bearing block 6 is provided with the motor mounting ring in axial outer gibbosity on the outside of the edge sealing of the pump housing 3
Seat 7；Neighbouring rotation cavity 2 is provided with a radiating and insulated cavity 8 on the bearing block 6；The edge sealing side footpath of the pump housing 3 is outside
End is provided with a horn-like external outlet pipe 9.
Shown in figure, end set of the central shaft hole 5 of bearing block 3 positioned at inner radiating and insulated cavity side has at least
The seal groove 10 being embedded together for sealing ring, the motor installation end that outside is located in the central shaft hole 5 of bearing block 3 are provided with for dynamic
The shaft type annular seal space 11 that sealing mechanism loads；The radiating of radial arrangement is additionally provided with the outer wall of the pump housing 3 of the side of bearing block 3
With reinforcement 12；Described horn-like external outlet pipe 9 is to be gradually transitions radially outlet from axial sides by arc pore,
An arc-shaped transition and the diminishing horn-like external outlet pipe 9 of bore are formed, improves water outlet efficiency.
The utility model can be used for existing centrifugal water pump according to prior art is supporting, and those skilled in the art exist
On the basis of solving the utility model content, using prior art and the knowledge of grasp, energy structure is advantageously carried out the utility model.
