Abstract
The utility model relates to a jet vacuum pump used for vacuum evaporation, dehydration, filtering, the diversion of a large-sized water pump, the absorption of toxic and harmful gas, etc. The utility model is developed to solve the problem that the present jet vacuum pump is easy to have return water and has lowered ultimate vacuum. The utility model comprises a base, a water tank, a motor, a water pump, a pipe line, a mixing chamber, a buffer tank, an intake port, etc., wherein, the mixing chamber comprises a pump body, a pump cover, a hole plate, etc. Seven holes are arranged on the hole plate of the jet vacuum pump in 600 type below, and thirteen holes are arranged on the hole plate of the jet vacuum pump in 800 type above. Owing to few holes on the hole plate, the utility model has concentrate flow speed, hard change of an intersection point, no return water and stable vacuum degree.
Description
The utility model relates to a kind of jet vacuum pump that is used for vacuum evaporation, dehydration, filtration, large pump diversion, absorption toxic and harmful etc.
Existing jet vacuum pump can be divided into 600 types following with the big class of two more than 800 types, on the orifice plate of the jet vacuum pump below 600 types 13-17 hole arranged; 800 types are above 15-18 hole.Because the hole is many, causes the horizontal intersection point malleable of current, often backwater causes ultimate vacuum to descend.
The purpose of this utility model is that a kind of flow velocity of development is concentrated, and intersection point is malleable not, no backwater, the jet vacuum pump that ultimate vacuum is stable.
Technical solution of the present utility model: below the existing jet vacuum pump is base 1, water tank 2, motor 3 and water pump 4 are housed on the base, be pipeline 5 on the water outlet of water pump, pipeline communicates with mixing chamber 6, and mixing chamber is made up of pump cover 7, orifice plate 8, the pump housing 9 etc.; There is intakeport 11 pipeline and knock out drum 10 connection places; We establish 7 holes on the jet vacuum pump orifice plate below 600 types, establish 13 holes on the jet vacuum pump orifice plate more than 800 types.
The utility model has the advantages that flow velocity is concentrated owing to hole on the orifice plate is few, intersection point is malleable not, no backwater, and ultimate vacuum is stable.
Accompanying drawing is a generalized section of the present utility model, among the figure: 1. base; 2. water tank; 3. motor; 4. water pump; 5. pipeline; 6. mixing chamber; 7. pump cover; 8. orifice plate; 9. the pump housing; 10. knock out drum; 11. intakeport; 12. vacuum gauge; 13. pressure gauge; 14. Venturi tube.
Embodiment: water tank 2, motor 3 and water pump 4 are installed on base 1, pipeline 5 is installed on the water outlet of water pump, establish mixing chamber 6 on pipeline top, mixing chamber comprises the pump housing 9, orifice plate 8, pump cover 7 etc., orifice plate 8 is positioned at the middle and upper part of mixing chamber, make the following jet vacuum pump of 600 types and on orifice plate, establish 7 holes, on the jet vacuum pump orifice plate more than 800 types, establish 13 holes.Intakeport 11 is established in connection place at pipeline and knock out drum 10.
