Abstract
Speed-increasing type jet pump is passed the utility model discloses one kind, it includes suction chamber, nozzle, mixed expansion room and flange.The suction chamber and mixed room of expanding are coaxially connected, and suction chamber snout cavity location and installation nozzle, the nozzle exit end of Taper Pipe shape faces the mixed throat for expanding room.The nozzle is made up of two conical tubes for saving coaxial but different coning angles, positioned at the cone angle alpha of the pitch circle Taper Pipe endoporus of entrance point one2=24 °~28 °, positioned at the cone angle alpha of the pitch circle Taper Pipe endoporus of the port of export one1=10 °~12 °.Because nozzle bore coning angle is first big after small so that the out-of-date acquisition substep speedup of liquid circulation, liquid stream speed-raising necessarily improves the suction vacuum of suction chamber, is conducive to being inhaled the suction of medium.Because a section endoporus coning angle of nozzle exit end is smaller, its outer wall radial dimension is also corresponding small, therefore nozzle does not occupy the inner chamber of suction chamber excessively, is conducive to increasing the volume ratio of suction chamber.
Description
Technical field
The utility model is related to a kind of water pump, specifically, and the utility model is related to a kind of jet pump, particularly one kind and passed
Speed-increasing type jet pump.
Background technology
Jet pump be it is a kind of itself there is no a pump product of mutual moving parts, this kind of pump utilizes high velocity stream under controlled condition
Dynamic liquid stream is driven by suction medium.Generally, the dynamic power by suction medium of liquid miscarriage green tape that jet pump sprays by nozzle.Institute
To say that nozzle is the core component of jet pump, its structure design is most important.The nozzle bore of jet pump is taper hole, the knot of taper hole
Structure and coning angle directly affect flow stream velocity.From nozzle oral area spray high speed liquid flow by suction chamber self-assembling formation low-pressure area,
The medium of suction chamber inspiration makees momentum-exchange with high speed liquid flow, is consequently formed one uniform mixed flow order and enters mixed expansion room.
Mixed room of expanding is also a kind of inner cone pipe component, and its coning angle is in opposite direction with nozzle coning angle, and gradually big structure causes the speed of mixed flow
Degree is gradually reduced, and speed can be changed into pressure energy with loss as small as possible.The nozzle of prior art is bored for a pitch circle
The Taper Pipe of angle α=15~20 °, although this single-unit necking shape Taper Pipe can reach the purpose for improving flow stream velocity, because in nozzle
Hole coning angle is slightly larger, and on the one hand composition nozzle profile is thick, and outer tube wall ties up the limited space of suction chamber.On the other hand because of circular cone
The slightly larger internal taper hole liquid resistance in angle also corresponding increase, so as to reduce flow stream velocity.Therefore, to subtract as far as possible in jet pump structure design
The coning angle in small nozzle inner pyramidal hole, to obtain faster flow stream velocity and bigger suction vacuum.
Utility model content
The utility model proposes that one kind passs speed-increasing type jet pump mainly for the deficiencies in the prior art, and the pump is retaining master
On the basis of body structure is constant, Structure Improvement Design only is carried out to nozzle, the coning angle in nozzle inner pyramidal hole is reduced by merogenesis, is made
Obtain out-of-date realize of liquid circulation and be segmented speedup.
The utility model is achieved through the following technical solutions technical goal.
Speed-increasing type jet pump is passed, it includes suction chamber, nozzle, mixed expansion room and flange.The suction chamber and mixed expansion room are coaxial
Connection, the snout cavity location and installation nozzle of suction chamber, the nozzle exit end of Taper Pipe shape faces the mixed throat for expanding room.The mixed expansion
The flange of room heavy caliber end outer wall suit is used for outer connection.It is theed improvement is that：The nozzle is coaxial but different round by two sections
The conical tube composition of cone angle, positioned at the cone angle alpha of the pitch circle Taper Pipe endoporus of entrance point one2=24 °~28 °, positioned at the pitch circle of the port of export one
The cone angle alpha of Taper Pipe endoporus1=10 °~12 °.
The nozzle total length L1, positioned at a long L of section of nozzle exit end2, L2=0.5~0.7L1。
The utility model compared with prior art, has the positive effect that：
1st, nozzle is made up of two conical tubes for saving coaxial but different coning angles, and simple in construction, making is easy；
2nd, nozzle bore coning angle is first big after small so that the out-of-date acquisition substep speedup of liquid circulation, liquid stream speed-raising is necessarily improved
The suction vacuum of suction chamber, is conducive to being inhaled the suction of medium；
3rd, the section endoporus coning angle positioned at nozzle exit end is smaller, and its outer wall radial dimension is also corresponding small, therefore nozzle
Do not occupy the inner chamber of suction chamber excessively, be conducive to increasing the volume ratio of suction chamber.
Brief description of the drawings
Fig. 1 is the utility model structural profile schematic diagram.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the utility model is described in further detail.
Speed-increasing type jet pump embodiment of passing shown in Fig. 1 is matched with 30m3In/h desalinization units, it includes suction chamber
1st, nozzle 2, mixed expansion room 3 and flange 4.The suction chamber 1 and mixed expansion room 3 are the main components of jet pump, and both are coaxially connected.Institute
The location and installation of nozzle 2 is stated in the snout cavity of suction chamber 1, the built-in port of export of nozzle 2 faces the mixed throat for expanding room 3.Suction chamber 1
It is a kind of multichannel cavity, the interface of the interface vacuumized and steam pumping is respectively equipped with the outer wall of both sides.The mixed expansion room 3 is big
Bore end outer wall suit flange 4, flange 4 is used for the outer supporting desalinator for seawater of connection.In order to further improve the suction of jet generation
Enter vacuum, the structure of the utility model lip-syncing mouth 2 has made optimization design, the improvement is that the nozzle 2 by two sections it is coaxial but
The conical tube composition of different coning angles, and the cone angle alpha of the pitch circle Taper Pipe of 2 entrance point of nozzle one2Than positioned at the pitch circle of the port of export one
The cone angle alpha of Taper Pipe1It is big many, α in the present embodiment2=25 °, α1=10°.Due to the port of export cone angle alpha of nozzle 21It is small, the section
Outer wall radial dimension is also corresponding small, therefore saves the intracavity space of suction chamber 1, and this structure, which is improved, makes suction chamber 1 increase by 8% suction
Enter amount.The utility model is to the Optimal Structure Designing of nozzle 2 in addition to coning angle has difference, and its length is also different.The overall length of nozzle 2 is
L1, the section length positioned at the port of export of nozzle 2 is L2, in order to ensure liquid stream passes through L2Fully pressure energy can be converted into during section
Speed energy, L2Segment length is at least the overall length L of nozzle 21Half, L in the present embodiment2=0.6L1.The L of this length2It is able to ensure that liquid
Stream is continued when by nozzle 2, stable speedup.Nozzle 2 spray high speed liquid flow by mix expander 3 trunnion when formed
Water seal plug effect so that the suction vacuum of suction chamber 1 effectively improves, the present embodiment suction vacuum reaches 98% or so.
It is higher by 5% or so than the supporting specified suction vacuum of desalinization unit.High level suction vacuum improves suction capactity naturally,
The present embodiment suction capactity improves 8% or so.The steam that the high speed liquid flow and suction chamber 1 that nozzle 2 sprays are aspirated expands in room 3 mixed
It is sufficiently mixed, because the mixed outlet section of room 3 that expands is horn-like Taper Pipe, extends out structure and the speed of mixed liquor stream is turned automatically again
Pressure energy is melted into, mixed liquor stream, which is pressed into the supporting desalinization unit of outer connection, makees desalt processing.
