Description
Technical field
The utility model relates to a kind of non-level diffuser structure of the pump housing of water pump, belongs to pump technology field.
Background technology
Conventional electric pump mainly has motor of the pump housing, pump cover and built-in impeller and impeller etc., on its middle pump body
It is configured with special diffuser and against impeller, the structure influence of the diffuser the pumpability of water pump, i.e. lift and water pump
Mechanical performance, but due to existing supporting diffuser unreasonable structure, attachment structure easily causes leakage etc., so as to need into
The adaptive improvement of row.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of simple structure, using peace
Dress is convenient, can be coordinated with impeller well, keeps pressure flow turnover smooth, improves the stator of the water pump of pumping efficiency
Body structure.
The purpose of this utility model by following technical solution completing, lead by a kind of diffuser structure of water pump, it
The inner barrel to be fixedly connected with centre by the outer cylinder body of a cone barrel is constituted, and the described water inlet osculum of outer cylinder body one end is arranged
There is bump joint, on the outer ring flange of bump joint, be evenly equipped with multiple connection through holes；The water outlet big opening end of the outer cylinder body sets
The thickening connection mouth of pipe is equipped with, and multiple screws is evenly equipped with the connection mouth of pipe end face for thickening；In described inner barrel outside wall surface
The stator of helix shape is provided with, and the annular water guide of outer expanding shape is formed between stator and the inwall of outer cylinder body lead to
Road, the tail end of the conduit pipe on the inside of the thickening connection mouth of pipe of outer cylinder body are formed with a transition arc and inside contract towards water outlet
The connection mouth of pipe of big opening end.
As preferred：The endoporus of described bump joint is a necking outside to inside, and with outer cylinder body water inlet osculum end
The junction in portion is formed with one by the restriction that the mouth of pipe is constituted is inside contracted, and the stator is corresponding to the transition circle connected on the inside of the mouth of pipe
Circular arc diversion edges are formed with arc.
This utility model belongs to improvements over the prior art, and it has simple structure, easy to install and use, can be with impeller
Coordinated well, keep pressure flow turnover smooth, improve pumping efficiency the features such as.

The water inlet osculum of outer cylinder body 1 one end 3 is provided with bump joint 4, is evenly equipped with multiple connections on the outer ring flange 5 of bump joint 4
Through hole 6；The water outlet big opening end 7 of the outer cylinder body 1 is provided with the thickening connection mouth of pipe 8, and equal on 8 end face of the connection mouth of pipe for thickening
It is furnished with multiple screws 9；The stator 10 of helix shape is provided with described 2 outside wall surface of inner barrel, and in stator 10 and outer tube
The annular conduit pipe 11 of outer expanding shape, the tail end of the conduit pipe 11, adding in outer cylinder body 1 is formed between the inwall of body 1
A transition arc 12 is formed with the inside of the thick connection mouth of pipe 8 and inside contracts the connection mouth of pipe 8 towards water outlet big opening end 7.
Shown in figure, the endoporus of bump joint described in the utility model 4 is a necking 13 outside to inside, and with outer cylinder body
The junction of water inlet osculum end 3 is formed with one by the restriction 14 that the mouth of pipe is constituted is inside contracted, and the stator 10 is corresponding to connection
Circular arc diversion edges 15 are formed with transition arc 12 on the inside of the mouth of pipe 8.
