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, an overflow pipe is arranged on the upper portion of one side of the tank body, a water inlet of the centrifugal pump is communicated with the tank body, a water outlet of the centrifugal pump is communicated with the ejector, a communicating pipe is arranged on the ejector, and the communicating pipe is connected with a fluid source after penetrating out of the tank body. The communicating pipe comprises a ceramic pipe, a rubber layer and a metal layer, wherein the ceramic pipe, the rubber layer and the metal layer are glued in sequence from inside to outside, and resin adhesive is applied between the rubber layer and the ceramic pipe and between the rubber layer and the metal layer. Working efficiency of the jet pump can be improved.
Description
Technical field
The present invention relates to a kind of Jet injector, belong to pump housing technical field.
Background technique
The vacuum that Jet injector utilizes fluid to come transferring energy and quality obtains 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 can be applied to the aspects such as minimizing 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 stoneware pipe, rubber layer and the metal layer of fitting successively from inside to outside described connecting tube, between described rubber layer and stoneware pipe, metal layer, be all coated with resin glue.
The improvement of technique scheme is: described rubber layer is sticked on stoneware pipe perisporium and combined by the sheet rubber being arranged in order.
The further improvement of technique scheme is: described resin glue is epoxy resin glue.
The further improvement of technique scheme is: described metal layer is involuted by fastening piece by two of symmetrical left and right.
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 flow out from spill pipe, thereby realize the transmission of fluid.
The present invention is owing to adopting stoneware pipe as connecting tube, directly contact with the liquid of transmission, make full use of the advantage of the smooth and easy manufacture of ceramic surface, thereby reduce current mobile resistance in runner, improve the efficiency of Jet injector, thereby reduced cost of production.Because pottery has stronger corrosion resistance, thereby the present invention adopts stoneware pipe as connecting tube, improved the corrosion resistance of connecting tube, reduced the replacement frequency of connecting tube, thereby further reduced cost of production.In addition, there is a rubber layer stoneware pipe perisporium is coated, utilize high elasticity and the high viscosity of rubber, can make it have good damping and shock-absorbing capacity, overcome the intrinsic low shortcoming of large, the shock-resistant ability of fragility of pottery, improved the reliability of connecting tube; At rubber layer outsourcing coating metal layer, utilize the advantage of metal layer good rigidity again, improved shock proof ability of connecting tube.。
Brief description of the drawings
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 shown in Figure 1, 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.
As shown in Figure 2, comprise from inside to outside stoneware pipe 6-1, rubber layer 6-3 and the metal layer 6-5 of laminating successively in the present embodiment connecting tube 6, between rubber layer 6-3 and stoneware pipe 6-1, metal layer 6-5, be all coated with resin glue, resin glue can adopt epoxy resin glue.
In the present embodiment, rubber layer 6-3 is sticked on stoneware pipe perisporium and is combined by the sheet rubber being arranged in order.The present embodiment has a rubber layer 6-3 stoneware pipe 6-1 perisporium is coated, utilize high elasticity and the high viscosity of rubber, can make it have good damping and shock-absorbing capacity, overcome the intrinsic low shortcoming of large, the shock-resistant ability of fragility of pottery, improve the reliability of connecting tube.
In order to facilitate the installation of metal layer 6-5, the present embodiment can be done following improvement: metal layer 6-5 is divided into two of symmetrical left and right, and two metal layers involute complete metal layer by fastening piece.
In the present embodiment, casing 1 is interior can also arrange vertical isolating plate 2, the live apart both sides of isolating plate 2 of spill pipe 5 and sparger 4, 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 sparger 4 to spray like this causes affects the smooth operation of centrifugal pump 3.
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.
