Abstract
The utility model discloses a kind of new-type annular jet pump.The utility model is by by suction passage, nozzle, suction room, trunnion, anemostat, outlet rectilinear(-al), by suction fluid by entering suction room by suction passage, working fluid enters suction room by nozzle, and the outlet for sucking room is sequentially connected with trunnion, anemostat and outlet straight line.Described nozzle will be surround by suction passage, form the nozzle of annular, nozzle by suction passage with being coaxially disposed.Compared with conventional center jet pump, the suction passage of annular jet pump does not hinder, and does not have to change by suction fluid or solid and flow to, and is therefore particularly suited for suction containing the high fluid-mixing of a large amount of solid particles or viscosity.
Description
Technical field
A kind of annular jet pump is the utility model is related to, the operating mode or needs two of the small-size annular jet pump that is particularly suitable for use in
Kind liquid mixes preferable operating mode.
Background technology
Jet pump is that one kind utilizes jet turbulence diffusion, to transmit the fluid machinery of energy and quality and hybrid reaction
Equipment.Typical jet pump is typically made up of parts such as nozzle, suction room, trunnion and anemostats.It is characterized in that itself is not transported
Dynamic component, simple in construction, and reliable operation, good airproof performance, suitably in high temperature, high pressure, vacuum, radiation and the specific condition such as underwater
Lower work.
Jet pump lifts the energy of low speed sucked liquid by high-speed jet, will be with other works so as to increase overall pressure energy
It is applied in combination as pump, the suction of whole device can be improved, improves cavitation performance.Just because of this series of advantages, jet pump exists
The each department of national economy such as farming, animal husbandry and fishery, hydraulic and electric engineering, communications and transportation and environmental protection are all widely used.
The content of the invention
The utility model is in view of the shortcomings of the prior art, there is provided a kind of new-type annular jet pump.
The utility model by by suction passage, nozzle, suction room, trunnion, anemostat, outlet rectilinear(-al), led to by suction fluid
Cross and suction room is entered by suction passage, working fluid enters suction room by nozzle, and the outlet for sucking room is sequentially connected with trunnion, diffusion
Pipe and outlet straight line.Described nozzle will be surround by suction passage, form the nozzle of annular, nozzle by suction passage with being coaxially disposed.
Furtherly, helix is carried on the inside of described nozzle, by suction passage inner side with helix, both spirals
Direction is reverse.
The beneficial effects of the utility model：
Compared with conventional center jet pump, the suction passage of annular jet pump does not hinder, and by suction fluid or solid not
Flowed to changing, be therefore particularly suited for suction containing the high fluid-mixing of a large amount of solid particles or viscosity.
The utility model forms reverse acting spiral stream, can so strengthen workflow using nozzle and by suction channel spiral line
Body and the mixed effect by suction fluid, shorten trunnion, reduce jet pump size.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
As shown in figure 1, the utility model is by by suction passage 1, nozzle 2, suction room 3, trunnion 4, anemostat 5, outlet straight line 6
Composition, during work, by suction fluid by entering suction room by suction passage, and working fluid enters suction room by nozzle, suction
The outlet of room is sequentially connected with trunnion, anemostat, outlet straight line.Nozzle therein will be surround by suction passage, i.e., by the outer of suction passage
It is ring-shaped to enclose as nozzle, the nozzle, and nozzle by suction passage with being coaxially disposed.Helix is carried on the inside of nozzle, by suction passage
Side is reverse with helix, both hand of spiral.
The course of work of the present utility model：By suction fluid and working fluid respectively by entering suction by suction passage and nozzle
Room, due in nozzle and being devised reverse acting spiral line on the inside of suction passage, so as to produce the transmission of spiral flow, more conducively energy,
The time of two kinds of fluids mixing and the length of trunnion can be shortened simultaneously, increase mixing liquid kinetic energy, and the shadow of smaller cavitation
Ring；Enter trunnion after sucking room, two fluids mixes in trunnion and carries out momentum-exchange, makes by the kinetic energy increasing of trandfer fluid
Add, most of kinetic energy is converted into pressure energy finally by anemostat.
The utility model contains a large amount of solid particles particularly suitable for suction（Ore, live fish, capsule etc.）Or viscosity is high
（Heavy oil）Fluid-mixing, being cleaned in ore in screening and the cleaning engineering field such as oil pipeline also has wide application background.
To sum up, the utility model proposes nozzle ring jet pump so that working fluid and be reverse acting spiral by suction fluid
Stream, avoid high-speed jet sticking wall flow it is dynamic caused by larger friction loss, and due to increase with by the contact area of suction fluid,
So that the peak efficiency of pump is promoted to 45% by 35.8%.
