Description

A kind of jet pump
Technical field
The present invention relates to a kind of jet pump, belong to pump housing technical field.
Background technology
Jet pump utilizes a fluid to transmit energy and the vacuum acquirement device of quality, using has the current of certain pressure to be sprayed by injection stream, owing to jet water course speed is the highest, is speed energy by pressure energy, make air-breathing district pressure drop low generation vacuum, under atmospheric pressure material is taken away.Jet pump has the advantages such as processing and fabricating is simple, it is safe, easy to maintenance to run, effect is preferable, it is suitable for different working environments and requirement, even can directly aspirate high concentration corrosive liquids, and can apply to reduce the aspects such as environmental pollution improves working conditions, there is the advantage that mechanical type, water-ring vacuum pump are incomparable.
But the conveying pipe in jet pump mostly is flexible hose at present, and corrosion resistance is poor, is not suitable for the production application under adverse circumstances.
Summary of the invention
The invention solves the problems that and technical problem is that: provide a kind of corrosion resistant jet pump, this jet pump can reduce the replacement cycle of communicating pipe, thus reduce production cost.
In order to solve above-mentioned technical problem, the technical scheme that the present invention proposes is: a kind of jet pump, including casing, centrifugal pump and ejector, described ejector is arranged on the top of casing, one upper lateral part of described casing is provided with overflow pipe, the water inlet of described centrifugal pump connects with casing, and the outlet of described centrifugal pump connects with ejector；Described ejector includes straight tube, the draw, trunnion and the anemostat being sequentially connected with, and is provided with and inserts this straight tube and extend to the nozzle of the draw, described straight tube is communicated with pipe, is connected with fluid source after described communicating pipe passing casing in described straight tube；Include earthenware described communicating pipe and be covered on the rubber layer of earthenware perisporium, application of resin glue between described earthenware and rubber layer；Described nozzle includes entrance, contraction section and the expansion segment being sequentially connected with, and described expansion segment is bigger compared with from contraction section bore nearby from contraction section bore at a distance.
The improvement of technique scheme is: described rubber layer is sticked on by the sheet rubber being arranged in order and combines on earthenware perisporium.
Improving further of technique scheme is: described resin glue is epoxide-resin glue.
Preferably, described expansion segment is the hollow circular-tube of taper.Further, the tapering of described hollow circular-tube is 60-80 degree.
Continuity theorem according to fluid, when fluid successively and stably flows through the pipeline that a thickness does not waits, owing to the fluid of a part any in pipeline all can not interrupt or extrude, therefore, within the same time, the quality and the fluid mass flowed out from another tangent plane that flow to the fluid of arbitrary tangent plane are equal.Further accordance with Bernoulli's theorem, when fluid flows in a pipeline, the local pressure that flow velocity is big is little, and the local pressure that flow velocity is little is big.When surface highlights, flow tube is relatively thin, and flow velocity is accelerated, and pressure reduces.
Therefore, when fluid is by specific expansion segment, forming whirlpool at the edge of expansion segment, this whirlpool makes expansion segment near exit form low-pressure area, and fluid just constantly flows into towards low-pressure area, can obtain the biggest speedup effect.The present invention is compared with the dilator of venturi tube structure, the flow velocity of fluid is faster, " vacuum " district formed on rear side of expansion segment outlet obtains lower negative pressure, fluid can be made to export faster in the anemostat of ejector, thus improve the work efficiency of jet pump under the pressure of air.
In use, described communicating pipe connects the present invention with fluid source (such as water source), and ejector forms " vacuum " district on rear side of jet expansion, fluid flows to region of no pressure under atmospheric pressure, and mix with the fluid of ejector ejection, then flow out from overflow pipe, thus realize the transmission of fluid.
Due to the fact that employing earthenware as communicating pipe, directly contacts with the liquid of transmission, make full use of that ceramic surface is smooth and the advantage that easily manufactures, thus reduce the resistance that current flow in runner, improve the efficiency of jet pump, thus reduce production cost.Owing to pottery has stronger corrosion resistance, thus the present invention uses earthenware as communicating pipe, improves the corrosion resistance of communicating pipe, reduces the replacement frequency of communicating pipe, thus reduce further production cost.It addition, be coated with rubber layer at earthenware perisporium, utilize high resiliency and the high viscosity of rubber, good damping and shock-absorbing capacity can be made it have, overcome the shortcoming that fragility is big, impact resistance ability is low that pottery is intrinsic, improve the reliability of communicating pipe.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of communicating pipe in Fig. 1.
Fig. 3 is the structural representation of ejector in Fig. 1.
Detailed description of the invention
Embodiment
The jet pump of the present embodiment is as shown in Figure 1, including casing 1, centrifugal pump 3 and ejector 4, ejector 4 is arranged on the top of casing 1, and a upper lateral part of casing 1 is provided with overflow pipe 5, the water inlet of centrifugal pump 3 connects with casing 1, and the outlet of centrifugal pump 3 connects with ejector 4；It is communicated with pipe 6 on ejector 4, is connected with fluid source after communicating pipe 6 passing casing 1.
As in figure 2 it is shown, include earthenware 6-1 in the present embodiment communicating pipe 6 and be covered on the rubber layer 6-2 of earthenware perisporium, being coated with resin glue between earthenware 6-1 and rubber layer 6-2, resin glue can use epoxide-resin glue.The present embodiment is coated with rubber layer 6-2 at earthenware 6-1 perisporium, utilizes high resiliency and the high viscosity of rubber, can make it have good damping and shock-absorbing capacity, overcomes the shortcoming that fragility is big, impact resistance ability is low that pottery is intrinsic, improves the reliability of communicating pipe.In the present embodiment, rubber layer 6-2 can use the sheet rubber being arranged in order to stick on earthenware perisporium to combine.
As shown in Figure 3, in the present embodiment, ejector 4 includes straight tube 4-1, draw 4-2, trunnion 4-3 and the anemostat 4-4 being sequentially connected with, being provided with in straight tube 4-1 and insert this straight tube 4-1 and extend to the nozzle of draw 4-2, straight tube 4-1 is provided with the communicating pipe 6 being connected with fluid source；Nozzle includes that entrance 4-6, contraction section 4-7 and the expansion segment 4-8 being sequentially connected with, expansion segment 4-8 are bigger compared with from contraction section 4-7 bore nearby from contraction section 4-7 bore at a distance.
In the present embodiment, expansion segment 4-8 is the hollow circular-tube of taper, and the tapering of hollow circular-tube is 70 degree.Certainly the tapering of hollow circular-tube can select the arbitrary value between 60-80 degree.
Can also arrange vertical division board 2, overflow pipe 5 and ejector 4 in the present embodiment in casing 1 to live apart the both sides of division board 2, the water inlet of centrifugal pump 3 and overflow pipe 5 are positioned at the same side of division board 2.The water level fluctuation that the high-velocity flow that so ejector 4 can be avoided to spray causes affects the steady operating of centrifugal pump 3.
