Abstract
The invention relates to a jet pump which comprises a box body, a centrifugal pump and an ejector, wherein the ejector is mounted at the top of the box body; an overflow pipe is arranged at the upper part on one side of the box body; the water inlet of the centrifugal pump is communicated with the box body; the water outlet of the centrifugal pump is communicated with the ejector; a communicating pipe is arranged on the ejector; the communicating pipe penetrates through the box body and then is connected with a fluid source; the communicating pipe comprises a ceramic pipe and a rubber layer attached to the peripheral wall of the ceramic pipe; and a resin adhesive is applied between the ceramic pipe and the rubber layer. The jet pump has stronger corrosion resistance and high working efficiency.
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 carry out the vacuum acquirement device of transferring energy and quality, adopting has the current of certain pressure to be sprayed by injection stream, because water-spraying flow velocity is high especially, is speed energy by pressure energy, make the low generation vacuum of air-breathing district Pressure Drop, under atmospheric pressure 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, different working environments and requirement can be adapted to, even can directly aspirate high concentration corrosive liquids, and the aspects such as minimizing environmental pollution improves working conditions can be applied to, there is the advantage that mechanical type, Nash hytor are incomparable.
But the delivery pipe at present in Jet injector mostly 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: provide a kind of corrosion resistant Jet injector, this Jet injector can reduce the replacement cycle of connecting tube, thus reduces cost of production.
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 described connecting tube passing casing with fluid source; Comprise stoneware pipe and the rubber layer being covered on stoneware pipe perisporium described connecting tube, between described stoneware pipe and rubber layer, be coated with resin glue.
The improvement of technique scheme is: described rubber layer is sticked on stoneware pipe perisporium by the sheet rubber be arranged in order and combines.
The further improvement of technique scheme is: described resin glue is epoxy resin glue.
The present invention in use, described connecting tube is communicated with fluid source (as water source), sparger forms " vacuum " district on rear side of jet expansion, fluid flows to region of no pressure under atmospheric pressure, and mix with the fluid that sparger sprays, then flow out from spill pipe, thus 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, thus the resistance that reduction current flow in runner, improve the efficiency of Jet injector, thus reduce cost of production.Because pottery has stronger corrosion resistance, thus the present invention adopts stoneware pipe as connecting tube, improves the corrosion resistance of connecting tube, reduces the replacement frequency of connecting tube, thus reduce further cost of production.In addition, there is rubber layer stoneware pipe perisporium is coated, utilize high elasticity and the high viscosity of rubber, good damping and shock-absorbing capacity can be made it have, overcome the shortcoming that intrinsic large, the shock-resistant ability of fragility of pottery is low, improve the reliability of connecting tube.
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 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, is connected after passing casing 1 connecting tube 6 with fluid source.
As shown in Figure 2, comprise stoneware pipe 6-1 and the rubber layer 6-2 being covered on stoneware pipe perisporium in the present embodiment connecting tube 6, be coated with resin glue between stoneware pipe 6-1 and rubber layer 6-2, resin glue can adopt epoxy resin glue.The present embodiment has rubber layer 6-2 stoneware pipe 6-1 perisporium is coated, utilize high elasticity and the high viscosity of rubber, good damping and shock-absorbing capacity can be made it have, overcome the shortcoming that intrinsic large, the shock-resistant ability of fragility of pottery is low, improve the reliability of connecting tube.
Can also arrange vertical isolating plate 2 in casing 1 in the present embodiment, spill pipe 5 and sparger 4 are lived apart the both sides of isolating plate 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 high-velocity flow sparger 4 can being avoided 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 the technological scheme of replacing and being formed, and are the protection domain of application claims.
