Description
Technical field
The present invention relates to jet pump accessory technical field, and in particular to a kind of jet pump bilayer stator.
Background technology
Jet pump is to spray to take away by the pump of trandfer fluid by nozzle at high speeds by the working fluid of certain pressure.Work
Fluid Qo from nozzle at high speeds spray when, form vacuum because the air of surrounding is swept away by jet in trunnion porch, conveyed
Fluid QS is to be inhaled into.Two fluids mixes in trunnion and carries out momentum-exchange, makes to be increased by the kinetic energy of trandfer fluid, finally
Most of kinetic energy is converted to by pressure energy by anemostat.And jet pump stator is one of them important accessory of jet pump.
Existing stator only one of which stator body, such as the plastics stators of JET1500 1800, this applies the water pump of this stator
Operation principle is as follows：When water pump vane works, the rotation that liquid passes through impeller, produced centrifugal force is by liquid from impeller
Outlet is thrown out, and the runner into stator is pressurized, water conservancy diversion, subsequently into the pump housing, is revolved because the liquid from stator out does
Transhipment is dynamic, so as to drive the liquid inside the pump housing also to rotate, makes the liquid inside the pump housing extremely unstable, the pressure of generation
It is fluctuated, it is extremely unstable, show that the pressure gauge on export pipeline is up and down；Further, since the current of pump body are not
Surely, the liquid inside water pump is made to have done certain idle work, efficiency declines;In addition, because pump body current are unstable, result in
Suction is also unstable, and suction typically fluctuates at 9.2 meters to about 9.6 meters.In view of this this stator also exists certain in design
Deficiency, it is difficult to reach customer requirement
The content of the invention
To solve problem above, the present invention is achieved through the following technical solutions：
A kind of jet pump bilayer stator, including stator body, also including a back shroud；On the side of the stator body
It is even to be provided with and gate vane channel into double reinforcement；Reinforcement array axis arrangement centered on the center of circle of the stator body
On the side of the stator body；The back shroud is have a resigning hole in the middle of cover body shape, and the back shroud；It is described
Positioning boss is provided with the middle of reinforcement, the back shroud resigning hole madial wall is provided with locating piece；The back shroud is by described
Locating piece and positioning boss supersonic welding are connected on described this body side surface of stator.
Preferably, the quantity of the reinforcement is 10.
Preferably, the inner surface light of the stator body smooth-sided compression candles, and the side of the reinforcement and the back shroud
It is sliding.
Beneficial effect：Simple structure of the present invention, the pressure stability of the pump housing, suction stabilization, overall effect can be made using the present invention
Rate also has and increases.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, it will be appreciated that structure of the invention
It is not limited in following examples：
As Figure 1-3, a kind of jet pump bilayer stator, including stator body 1, also including a back shroud 2；In stator body
It is uniformly provided with 1 side and gate vane channel into double reinforcement 3；The axle battle array centered on the center of circle of stator body 1 of reinforcement 3
Row are arranged on the side of stator body 1；Back shroud 2 is have a resigning hole 5 in the middle of cover body shape, and back shroud 2；Reinforcement
Positioning boss 31 is provided with the middle of 3, the madial wall of resigning hole 5 of back shroud 2 is provided with locating piece 51；Back shroud 2 passes through locating piece 51
It is connected on the side of stator body 1 with supersonic welding with positioning boss 31.Make to be formed between adjacent reinforcement 3 and back shroud 2
Circulation road.
The quantity of reinforcement 3 is 10.
The smooth-sided compression candles of stator body 1, and the side of reinforcement 3 and the inner surface of back shroud 2 are smooth.
Stator body of the invention can be the plastics stators of jet pump JET1500 1800.
Operation principle：Original stator is designed to two parts, is exactly to increase by one on the basis of original stator body 1
Back shroud, welds two parts by ultrasonic wave, keeps constant with original installation dimension, this addresses the problem stator
Interchangeability.Stator after improvement is an enclosed stator, that is from stator liquid out not rotating, but logical
Later the effect of cover plate 2 and reinforcement 3, direction is changed by the rotary motion of liquid, along back shroud 2 and the direction of reinforcement 3,
From the bottom trickle of back shroud 2, the liquid at this moment flowing out is very steady, eliminate liquid pump body done it is useless
Work(, it is also highly stable to be reflected in manometric reading on outlet pipeline, suction not in fluctuation, typically at 9.8 meters, the overall effect of pump
Rate also improves 3-4%.
In a word：Stator improve after the pump housing pressure stability, suction stabilization, overall efficiency also has and increases, and following table is before improving
With the overall target table of comparisons after improvement：
Use the performance parameter of the jet pump of traditional stator：
Use the performance parameter of jet pump of the invention：
General principle of the invention and principal character and advantages of the present invention has been shown and described above.Those skilled in the art should
The understanding, the present invention is not limited to the above embodiments, simply illustrates of the invention described in above-described embodiment and specification
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, and these change and change
Enter all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent
Define.
