The utility model is achieved through the following technical solutions technical goal.
Vapour-liquid is polyblended type jet pump, and it comprises the preposition suction chamber that coaxial and order is connected, rearmounted suction chamber and mixedly expands room, and the first order jet nozzle established in preposition suction chamber and secondary nozzle.Described preposition suction chamber is rectangular shape tee pipe fitting, working water entrance point and water outlet end coaxial, be provided with the suction port vertically communicated between true.Its improvements are: establish the Taper Pipe that outer imperial palace is little in the working water entrance point of described preposition suction chamber, and Taper Pipe small end oral area axially installs first order jet nozzle.Establish step hole location and installation secondary nozzle in the water outlet end of opposite side, the mixed import of expanding room of outlet docking of secondary nozzle, the outlet bore of secondary nozzle equals mixed and expands room import bore.
As further improvement project, establish two pitch cone angles not wait in described secondary nozzle and length endoporus not etc., wherein preposition horn mouth tapering is 50
0~ 55
0, long 10 ~ 15mm, the taper hole cone angle of a remaining joint is 70
0~ 10
0, long 50 ~ 80mm.
As further improvement project, described first order jet nozzle length is shorter than secondary nozzle, and both length differences are 1.5 ~ 2.0 times.
As further improvement project, the outlet relative aperture secondary nozzle outlet bore of described first order jet nozzle is little, and both bore differences are 5 ~ 15mm.
As further improvement project, the mixing section of described mixed expansion room is isometrical straight tube, and its length is 8 ~ 10 times of mixing section bore.
The utility model compared with prior art, has following good effect:
1, two coaxial structures alternately of nozzle are relatively simple, make easily, accurate positioning, installation be convenient;
2, the working water introduced is through two joint nozzle relay speed-raisings, the pressure energy strengthening working water converts the ability of kinetic energy to, the degree of vacuum of the high-velocity fluid produced by making suction port place form higher value during preposition suction chamber, high level degree of vacuum is conducive to improving suction capactity, facilitate the brine accumulated in water generating machine and the water vapor do not condensed to be sucked in the lump, vapour-liquid is polyblended and is greatly improved work efficiency;
3, lengthen the mixed mixing section expanding room, be conducive to working water and aspirate the brine that comes up and non-water of condensation steam Homogeneous phase mixing, significantly reducing running noises.
Accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Vapour-liquid shown in Fig. 1 is polyblended type jet pump, and it comprises preposition suction chamber 1 that coaxial and order is connected, rearmounted suction chamber 3 and mixedly expands room 5, and the first order jet nozzle 2 established in preposition suction chamber 1 and secondary nozzle 4.Described preposition suction chamber 1 is the main component in the utility model, it is a kind of likeness in form rectangular shape tee pipe fitting, the working water entrance point being in left end is coaxial with the water outlet end being in right-hand member, is provided with the suction port 1.1 vertically communicated between working water entrance point and water outlet end.Be positioned at the flange of suction port 1.1 for connecting external pipe, suction port 1.1 is by the brine accumulated in externally connected pipe UNICOM machine and non-water of condensation steam.In the utility model preposition suction chamber 1 working water entrance point in establish the Taper Pipe that outer imperial palace is little, be positioned at inner Taper Pipe small end oral area and axially first order jet nozzle 2 be installed.Step hole location and installation secondary nozzle 4 is established in the water outlet end being located at preposition suction chamber 1 opposite side, secondary nozzle 4 is coaxial with preposition first order jet nozzle 2, although there is part fit between the two, between leave space for the medium circulation be sucked from suction port 1.1.Secondary nozzle 4 is junction location and installation between preposition suction chamber 1 and rearmounted suction chamber 3, and the main body of secondary nozzle 4 stretches in rearmounted suction chamber 3, and to export the mixed import of expanding room 5 of docking, the outlet bore of secondary nozzle 4 equals mixed and expands room 5 import bore.In the utility model, the mixed mixing section of room 5 that expands is for the isometrical straight tube of lengthening, and elongate structure is conducive to working water and aspirates the brine, the non-water of condensation steam Homogeneous phase mixing that come up, significantly can reduce running noises.
During the actual use of the utility model, the working water of introducing is sprayed through first order jet nozzle 2, and continuous print jet forms the degree of vacuum suitable with prior art at the suction port 1.1 of preposition suction chamber 1.Because of first order jet nozzle 2 outlet directly and secondary nozzle 4 gap fit, the jet exported from first order jet nozzle 2 and be drawn into medium from the suction port 1.1 of preposition suction chamber 1 and enter secondary nozzle 4 in the lump, the energy of the impinging jet forming secondary injection improves further, thus strengthen the suction port 1.1 place degree of vacuum of preposition suction chamber 1, suction capactity is promoted under high level degree of vacuum, facilitate the brine accumulated in water generating machine and the water vapor do not condensed to be sucked in the lump, vapour-liquid is polyblended and is greatly improved work efficiency.Generally speaking, the suction port 1.1 place degree of vacuum of hydraulic performance of the present utility model, particularly preposition suction chamber 1 determines, below with inhalation flow: 1.5m primarily of supporting two joint nozzle arrangements and size
3/ h, suction head: 8.9m, head pressure 0.05MPa, working water pressure 0.35 MPa, working water flow 13m
3the vapour-liquid of/h specification type the jet pump that polyblends is embodiment, the nozzle of equipped different structure size in permission range, and make hydraulic performance test respectively, concrete test structure sees the following form:
(certain specification) vapour-liquid is polyblended type jet pump inner spray nozzle pairing embodiment hydraulic performance test table
From above-described embodiment test data, the degree of vacuum that this specification obtains at suction port 1.1 place of preposition suction chamber 1 is all very high, but numerical value slightly difference, wherein embodiment 1 numerical value is minimum, and embodiment 3 numerical value is the highest.Although the degree of vacuum of embodiment 3 is 667.67mmHg, the 500mmHg degree of vacuum also obtained at suction port than prior art is high.Because suction port 1.1 degree of vacuum of suction chamber 1 preposition in the utility model is high, significantly increase suction capactity, the brine making accumulation in water generating machine and the water vapor do not condensed are extracted out in the lump, and vapour-liquid is polyblended and greatly improved water generating machine manufacturing efficiency.
