Embodiment
Like Fig. 1~a kind of jet pump shown in Figure 2; Comprise suction tube 1, nozzle 2, trunnion inducer 3, trunnion 4, diffusing tube 5, annular jet 6; The material feeding mouth of inner chamber one end of nozzle 2 for being connected with suction tube 1, the other end is a discharge port, the bore of discharge port is greater than the bore of material feeding mouth; One end of nozzle 2 is cylindric, and the other end is a bell mouth shape.The discharge port of nozzle 2 inner chambers is connected with trunnion inducer 3, trunnion 4, diffusing tube 5 orders, and the entrance point bore of trunnion inducer 3 is greater than outlet end, and trunnion inducer 3 is a bell mouth shape.The outlet end bore of diffusing tube 5 is greater than entrance point, and diffusing tube 5 is a bell mouth shape.Nozzle 2 outsides are provided with air chamber 15 in the form of a ring; Air chamber 15 is connected with suction tude 7; Be provided with the annular gap 8 of ventilation between the inwall of annular jet 6 and the nozzle 2; Gap 8 one ends are connected with the entrance point of trunnion inducer 3, and the other end in gap 8 is connected with air chamber 15 through the annular chamber of the bell mouth shape that bore enlarges gradually.
Gap 8 is a straight line shape along the ventilation direction.Suction tube 1 is welded on first flange 9, and first flange 9 and second flange 10 are fastenedly connected.The feed end of nozzle 2 is connected with second flange 10.Annular jet 6 both sides are connected with the 3rd flange 11, the 4th flange 12 respectively.Trunnion 4 is provided with the 5th flange 13 and the 6th flange 14 that links together with the joint of diffusing tube 5.Suction tube 1 is coaxial with nozzle 2, annular jet 6, trunnion inducer 3, trunnion 4 and diffusing tube 5.
A kind of suction method of jet pump, method may further comprise the steps:
A) pressurized air gets into air chamber 15 from suction tude 7; Pressurized air is ejected on the import end wall of trunnion inducer 3 from the gap cathetus between nozzle 2 and the annular jet 6 with ultrasonic air-flow; Pressurized air is with the inwall flow at high speed of supersonic airstream along trunnion inducer 3; Take away the air in trunnion inducer 3, nozzle 2 inner chambers and the suction tube 1, produce negative pressure;
B) the absorbate body is inhaled into suction tube 1 under atmospheric pressure and the effect of object static pressure, enters into nozzle 2 and trunnion inducer 3 again, and brings in the trunnion 4 with high velocity air, and in trunnion 4, carries out energy interchange;
C) in trunnion 4, high velocity air passes to the absorbate body with part kinetic energy, and the absorbate rate of flow of fluid is accelerated, and air-flow velocity progressively slows down; When arriving trunnion 4 outlet end, the flow velocity of air-flow and absorbate body reaches unanimity, and fully mixes, and mixed air-flow and object get into diffusing tube 5; In diffusing tube 5, air-flow velocity progressively reduces, and pressure rises; The absorbate body extrudes diffusing tube 5, discharges the pump housing, accomplishes the suction of jet pump.
This jet pump be fully with pressurized air as working medium, its working state is to cross the turbulent fluctuation effect special delivery ability of object with the air communication of supersonic speed motion, has high degree of vacuum and very strong suction capacity.Because no matter suction tube 1 when inhaling the absorbate body, is gas, liquid or the shape solid that looses, and suction can not occur and stop up, so this jet pump is applicable to intake-gas, liquid and diffusing shape solid.Because the designs of nozzles of this jet pump is a ring-type shape nozzle, its suction pipe, trunnion and expanding duct are arranged on same the axis, and nozzle makes gas, liquid and the diffusing shape solid of suction in jet pump, need not change the flow direction at the end of suction pipe.
This jet pump is that to make the work medium with pressurized air be power.For a long time, people are to slow as the theoretical research and the experiment progress of the jet pump of working medium with pressurized air, and the overwhelming majority all is to be the research and the improvement of the jet pump of main medium to water and steam.And inexhaustible natural air is used few, fully using natural air is that power is technological innovation as the pump work medium.
This jet pump uses air dielectric to be power fully, and degree of vacuum is high, has very strong suction capacity, can carry poisonous and radioactive material and discharge of noxious gases; This jet pump can be designed to automatic control, remote control simultaneously, thereby is applicable to high temperature, high pressure, deep water, intense radiation, and particular surroundingss such as deep-etching are applicable in addition and draw fluid and the larger particles solid material that contains higher concentration.The pressurized air source is provided by air compressor, can select the model of air compressor according to own needs.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the technological scheme of the utility model to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
