Abstract
The invention relates to a jet pump which comprises a tank body, a centrifugal pump and an ejector. The ejector is mounted on the top of the tank body, a water inlet of the centrifugal pump is communicated with the tank body, and a water outlet of the centrifugal pump is communicated with the ejector. The ejector comprises a straight pipe, a contracted pipe, a throat pipe and a diffusion pipe, the straight pipe, the contracted pipe, the throat pipe and the diffusion pipe are connected in sequence, a nozzle inserted into the straight pipe and extending to the contracted pipe is arranged in the straight pipe, and the straight pipe is provided with a communicating pipe. The nozzle comprises an inlet, a contraction section and an expansion section, wherein the inlet, the contraction section and the expansion section are connected in sequence, and the caliber of the position, far away from the contraction section, of the expansion section is larger than the caliber of the position, close to the contraction section, of the expansion section. The flow speed of working fluid in the jet pump can be improved, and working efficiency of the jet pump can be further improved.
Description
Technical field
The present invention relates to a kind of Jet injector, belong to pump housing technical field.
Background technique
Jet injector utilizes fluid to come the vacuum of transferring energy and quality to obtain device, employing has the current of certain pressure to spray by injection stream, because water-spraying flow velocity is high especially, changes pressure energy into speed energy, make air-breathing district pressure decreased produce vacuum, under atmospheric effect, material is taken away.Jet injector has the advantages such as processing and fabricating is simple, security of operation, easy to maintenance, effect is better, can adapt to different working environments and requirement, even can directly aspirate high concentration corrosive liquids, and the aspect such as can be applied to reduce that environmental pollution improves working conditions, there are mechanical type, the incomparable advantage of Nash hytor.
But the delivery pipe of using in Jet injector mostly at present is flexible hose, and corrosion resistance is poor, is not suitable for the production application under rugged environment.
Summary of the invention
The present invention wants technical solution problem to be: a kind of corrosion resistant Jet injector is provided, and this Jet injector can reduce the replacement cycle of connecting tube, thereby reduces production costs.
In order to solve the problems of the technologies described above, the technological scheme that the present invention proposes is: a kind of Jet injector, comprise casing, centrifugal pump and sparger, described sparger is arranged on the top of casing, one upper lateral part of described casing is provided with spill pipe, and the water inlet of described centrifugal pump is communicated with casing, and the water outlet of described centrifugal pump is communicated with sparger, described sparger is provided with connecting tube, is connected after passing casing described connecting tube with fluid source; Comprise metal tube and the ceramic plate that is covered on inner wall of metal tube described connecting tube, described inner wall of metal tube is provided with counterbore, and described ceramic plate is provided with the ceramics pole that can insert corresponding counterbore, between described metal tube and ceramic plate, is coated with resin glue.
The improvement of technique scheme is: the cross section of described ceramic plate is trapezoidal for what radially inwardly shrink gradually along metal tube, is also coated with resin glue between the side of adjacent ceramic plate.
The further improvement of technique scheme is: the outer surface of described ceramics pole is provided with uniform granular projection.
The present invention in use, described connecting tube is communicated with fluid source (as water source), sparger forms " vacuum " district at jet expansion rear side, fluid flows to region of no pressure under atmospheric effect, and mix with the fluid of sparger ejection, then from spill pipe, flow out, thereby realize the transmission of fluid.
The present invention is due to the ceramic plate with ceramics pole is evenly inserted into the metal tube with counterbore, between metal tube and ceramic plate, be coated with resin glue simultaneously, therefore increased the laminating ability between metal tube and ceramic plate, make to be not easy connecting tube of the present invention to come off and damage, scurf resistance and working life have been improved, can effectively reduce the replacement frequency of connecting tube, thereby reduce cost of production.Because pottery is more corrosion-resistant compared with metal, thereby the present invention is by avoiding metal directly to contact with corrosive fluid, has improved the corrosion resistance of connecting tube, has further reduced the replacement frequency of connecting tube, thereby has further reduced cost of production.In addition, the advantage that the present invention can utilize ceramic plate smooth surface and easily manufacture, reduces liquid mobile resistance within connecting tube, improves and has produced efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of connecting tube in Fig. 1.
Embodiment
Embodiment
The Jet injector of the present embodiment as depicted in figs. 1 and 2, comprise casing 1, centrifugal pump 3 and sparger 4, sparger 4 is arranged on the top of casing 1, and a upper lateral part of casing 1 is provided with spill pipe 5, the water inlet of centrifugal pump 3 is communicated with casing 1, and the water outlet of centrifugal pump 3 is communicated with sparger 4; Sparger 4 is provided with connecting tube 6, passes casing 1 connecting tube 6 and is connected with fluid source afterwards; Comprise metal tube 6-1 and the ceramic plate 6-2 that is covered on metal tube 6-1 inwall connecting tube 6, metal tube 6-1 inwall is provided with counterbore, and ceramic plate 6-2 is provided with the ceramics pole 6-3 that can insert corresponding counterbore, between metal tube 6-1 and ceramic plate 6-2, is coated with resin glue.In the present embodiment, resin glue can adopt epoxy resin glue.
In the present embodiment, the cross section of ceramic plate 6-2 is radially inwardly shrink gradually along metal tube 6-1 trapezoidal, between the side of adjacent ceramic plate 6-2, is also coated with resin glue, and the outer surface of ceramics pole 6-3 is provided with uniform granular projection.Granular projection can increase the combination force of ceramic plate 6-2 and metal tube 6-1, further prevents that ceramic plate 6-2 from coming off from metal tube 6-1.
In the present embodiment, casing 1 is interior can also arrange vertical isolating plate 2, the both sides of spill pipe 5 and sparger 4 separation isolating plates 2, and the water inlet of centrifugal pump 3 and spill pipe 5 are positioned at the same side of isolating plate 2.The water level fluctuation that the high-velocity flow that can avoid like this sparger 4 to spray causes affects the smooth operation of centrifugal pump.
The present invention is not limited to the concrete technological scheme described in above-described embodiment, and in addition to the implementation, the present invention can also have other mode of executions.All employings are equal to replaces the technological scheme forming, and is the protection domain of requirement of the present invention.
