Utility model content
In order to solve the above-mentioned technical problem the weak point in, the utility model provides a kind of novel injection pump.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:A kind of novel injection pump, including pump Body, casing and injector, injector are arranged on the top of casing, and a upper lateral part of casing is provided with overflow pipe, the water inlet of the pump housing Connected with the delivery port of casing, the delivery port of the pump housing is connected with the first fluid entrance of injector;Injector include nozzle body, Connection housing and diffuser portion;Fluid tip is provided with nozzle body, connection housing includes collecting Mixed Zone and delivery area Domain;
Collect Mixed Zone to be connected with nozzle body, away from nozzle body one end cross-sectional area along nozzle body Axis direction be gradually reduced;Conveyor zones are straight cylindrical, and conveyor zones one end is connected with Mixed Zone, the other end with diffusion Device portion connects, and the cross-sectional area for including scattered device portion away from nozzle body one end gradually increases along the axis direction of nozzle body;Spray The second fluid entrance of emitter is arranged on the side of nozzle body, perpendicular to the first path of first fluid entrance;Fluid tip On the first path of first fluid entrance, and extend to and collect in Mixed Zone.
Fluid tip is arranged on the first path by clamping device.
Screen pack is installed on first path of first fluid entrance.
The pipeline of the alternate path of second fluid entrance is two-layer, and outer layer is metal, internal layer is ceramics.
Cushion is provided with casing, cushion is arc, at the lower exit port of injector.
The utility model simple structure, installs assembling easily, increases the fluid velocity of jet pump, improves work effect Rate.

Specific embodiment
As shown in Figure 1 and Figure 2, the utility model includes the pump housing, casing 2 and injector 1, and injector 1 is arranged on casing 2 Top a, upper lateral part of casing 2 is provided with overflow pipe 3, and the water inlet of the pump housing is connected with casing delivery port 4, the delivery port of the pump housing with The first fluid entrance 11 of injector 1 is connected;Injector 1 includes nozzle body 13, connection housing 14 and diffuser portion 15;Nozzle Fluid tip 16 is provided with housing 13, connection housing 14 includes collecting Mixed Zone and conveyor zones;
Collect Mixed Zone to be connected with nozzle body 13, away from nozzle body 13 one end cross-sectional area along nozzle The axis direction of housing 13 is gradually reduced;Conveyor zones are straight cylindrical, and conveyor zones one end is connected with Mixed Zone, the other end Be connected with diffuser portion 15, include scattered device portion 15 away from the one end of nozzle body 13 cross-sectional area along nozzle body 13 axis side To gradually increasing;The second fluid entrance 12 of injector 1 is arranged on the side of nozzle body 13, perpendicular to first fluid entrance 11 The first path;Fluid tip 16 is arranged on the first path of first fluid entrance 11, and is extended to and collected in Mixed Zone.
The utility model when in use, when fluid is by the fluid tip of injector, collect the both sides of Mixed Zone with Whirlpool is formed between nozzle body and forms negative pressure, fluid is just constantly flowed into towards negative pressuren zone, can obtain very big speedup effect. Fluid output faster to the diffusion part of injector can be made under the pressure of air, so as to the work that improve jet pump is imitated Rate.Specifically, second fluid entrance is connected by alternate path with second fluid storage part, the first fluid entrance of injector The first path through the both sides of fluid tip exit by negative pressure shape into region of no pressure, fluid flows to vacuum under atmospheric pressure Area, and mixed with the fluid of injector ejection, then flowed out from overflow pipe, so as to realize the transmission of fluid.
Fluid tip 16 is arranged on the first path by clamping device 5, can be according to specific inlet pressure, outlet pressure Power carries out the front and rear adjustment of axis direction.Additionally, the utility model is provided with the first path of first fluid entrance 11 Screen pack 7, the pipeline of the alternate path of second fluid entrance 12 is two-layer, and outer layer is metal, internal layer is ceramics.
In addition, the utility model is provided with cushion 6 in casing 2, cushion 6 is arc, positioned at the lower section of injector 1 Exit.So when the fluid for exporting out from injector can slow down cymomotive force in the presence of cushion, with guarantee and case The steady running of the pump housing of body outlet connection.
Above-mentioned implementation method is not that, to limitation of the present utility model, the utility model is also not limited to the example above, Change, remodeling, addition or replacement that those skilled in the art are made in the range of the technical solution of the utility model, Also protection domain of the present utility model is belonged to.
