Abstract
The utility model discloses a vacuum pump, which belongs to the field of mechanical vacuum devices. A water tank is connected with a pipeline by the aid of a pipeline pump; a high-pressure chamber arranged at an output end of the pipeline is connected with a vacuum chamber; a porous plate is arranged at the connecting position of the high-pressure chamber with the vacuum chamber; a spray nozzle arranged on the porous plate is fixedly connected onto the porous plate in a threaded manner; an output pipe is arranged at the lower end of the vacuum chamber and connected with a back pressure pipe; and the tail end of the back pressure pipe is placed into the water tank. The vacuum pump has the advantages of simple structure, high corrosion resistance, low failure rate and convenient maintenance.
Description
Technical field
The utility model relates to a kind of mechanical vacuum apparatus, relates in particular to a kind of vacuum pump.
Background technique
Vacuum pump is used for extracting or conveying gas more.Along with developing rapidly of industrial or agricultural and scientific research cause, all trades and professions are growing to the demand of vacuum pump.
In prior art, Nash hytor is the most general, and Nash hytor mainly adopts main shaft and impeller to form impeller-spindle unit; Front pump cover and prime suction and discharge parts are formed the front pump cover parts; Rear pump cover is formed the rear pump cover parts with back level suction and discharge parts; Impeller-spindle unit is contained in the pump chamber parts, and air pipe is connected with front pump cover and rear pump cover, and the fore bearing gland is connected with bearing bracket stand; The machine sealed cover is connected with front pump cover; Water pipe is connected on front pump cover, rear pump cover, the pump housing.
Because it is when being with corrosive gas that pump housing material adopts gray cast iron, flowing medium, because the impeller high speed rotating, pressurized gas, very strong to cavitation erosion, the corrosion of the pump housing, influence the degree of vacuum of pump, the working life of having reduced pump.
The model utility content
The purpose of this utility model provides a kind of degree of vacuum height, and corrosion resistance is strong, and rate of fault is low, vacuum pump easy to maintenance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of vacuum pump comprises pond, pipeline mounted pump, pipeline, hyperbaric chamber, porous slab, nozzle, one-way valve, positioning disk, output tube, back pressure pipe and vacuum chamber.
Be connected by pipeline mounted pump between pond and the pipeline, the output terminal of pipeline is the hyperbaric chamber, the hyperbaric chamber links to each other with vacuum chamber, the joint of hyperbaric chamber and vacuum chamber is provided with porous slab, porous slab is provided with nozzle, and nozzle adopts screwed connection to be fixed on the porous slab, and the lower end of vacuum chamber is provided with output tube, output tube links to each other with the back pressure pipe, and the end of back pressure pipe places the pond.
Be provided with positioning disk in the described vacuum chamber.
The sidewall of described vacuum pump is provided with intakeport, and intakeport is provided with one-way valve.
The beneficial effects of the utility model are:
The utility model is simple in structure, and is with low cost, and corrosion resistance is strong, and rate of fault is low and easy to maintenance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, pond; 2, pipeline mounted pump; 3, pipeline; 4, hyperbaric chamber; 5, porous slab; 6, nozzle; 7, one-way valve; 8, positioning disk; 9, output tube; 10, back pressure pipe; 11, vacuum chamber.
Embodiment
A kind of vacuum pump comprises pond 1, pipeline mounted pump 2, pipeline 3, hyperbaric chamber 4, porous slab 5, nozzle 6, one-way valve 7, positioning disk 8, output tube 9, back pressure pipe 10 and vacuum chamber 11.
Be connected by pipeline mounted pump 2 between pond 1 and the pipeline 3, the output terminal of pipeline 3 is hyperbaric chamber 4, and hyperbaric chamber 4 links to each other with vacuum chamber 11; Hyperbaric chamber 4 is provided with porous slab 5 with the joint of vacuum chamber 11, porous slab 5 is provided with nozzle 6, and nozzle 6 adopts screwed connection to be fixed on the porous slab 5, and the lower end of vacuum chamber 11 is provided with output tube 9, output tube 9 links to each other with back pressure pipe 10, and the end of back pressure pipe 10 places pond 1.
Be provided with positioning disk 8 in the described vacuum chamber 11.
The sidewall of described vacuum pump is provided with intakeport, and intakeport is provided with one-way valve 7.
During use, open pipeline mounted pump 2, the water that has high pressure is admitted to hyperbaric chamber 4, and enters vacuum chamber 11 by the nozzle on the porous slab 56, and the water column of all nozzle 6 ejections all concentrates high velocity jet to the central point of output tube 9, enters in the pond 1 by back pressure pipe 10 again.Positioning disk 8 in the vacuum chamber 11 plays the effect of guiding, makes on the central point that is sprayed onto output tube 9 that water column all concentrates.The big principle of local pressure that the local pressure big according to flow velocity in the fluid mechanics is little, flow velocity is little, make positioning disk 8 around form vacuum.Gas sucks from intakeport, because the intakeport place is provided with one-way valve 7, can prevent gas backstreaming effectively.
Nozzle 6 adopts screwed connection to be fixed on the porous slab 5, is convenient to dismounting and maintenance.
