The centrifugal pump solves the problems that an existing centrifugal pump is simple in installation structure, poor in overall fixing effect and easy to crack at an overall inclined pipeline connector. This precision type multistage centrifugal pump shocks resistance, including the motor and the pump head of the vertical setting of mutually supporting, support through the stand between motor and the pump head and be connected, its pump shaft passes from the stand center and is connected with the pump head, has through screwed connection between stand and the motor flange face and is the horizontally fixed plate, and the delivery port department of pump head is connected with the pipeline, and the pipeline is bent and is made the opening up and pass the fixed plate and link to each other with the fixed plate through the stay. The utility model discloses a set up the fixed plate and be used for fixed pipeline between motor and pump head to increase holistic tightness through the screw rod, make locking between fixed plate and the ground with the pull ring again, wholly can not produce the slope, it is more firm to have overall structure, the difficult advantage that ftractures of pipeline.
Description
Technical Field
The utility model belongs to the technical field of fluid machinery, a water pump is related to, in particular to precision type multistage centrifugal pump shocks resistance.
Background
The centrifugal pump works by centrifugal motion of water generated by high-speed rotation of an impeller, when liquid is thrown to the periphery from the center of the impeller, a low-pressure area is formed at the center of the impeller, the liquid is sucked into the center of the impeller under the action of atmospheric pressure, and the liquid is continuously sucked and discharged by means of continuous operation of the impeller. The centrifugal pump is in industrial application especially under the abominable condition of environmental environment, because the use of machineshop car and various main equipment, the installation of centrifugal pump will be in constantly shaking, still can take place the impact of stereoplasm solid debris, and its mounting structure of conventional centrifugal pump is comparatively simple, and holistic fixed effect is poor, makes the kneck fracture of whole slope pipeline easily, produces certain influence to water pump normal use.
Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide an overall structure is firm installation back not easy inclined's anti-impact precision type multistage centrifugal pump more.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides an accurate multistage centrifugal pump shocks resistance, is including the motor and the pump head of the vertical setting of mutually supporting, its characterized in that, motor and pump head between support through the stand and connect, its pump shaft passes from the stand center and is connected with the pump head, stand and motor flange face between be the horizontally fixed plate through screwed connection, the delivery port department of pump head is connected with the pipeline, the pipeline bend and make the opening up and pass the fixed plate and pass the stay and link to each other with the fixed plate.
The impact-resistant precision multistage centrifugal pump has the technical effects that: support the motor through increasing the stand on the basis of traditional vertical centrifugal pump to set up the fixed plate between stand and motor, the pipeline tip of the fixed pump head delivery port department of rethread fixed plate has increased the plane in other words and has fixed, consequently is difficult for taking place translation or crooked under the condition that the pipeline received the impact, and each flange joint face of pipeline can not ftracture, and overall structure is firmer.
In foretell precision type multistage centrifugal pump shocks resistance, fixed plate and pump head between vertically be provided with a plurality of screws, the screw rod be circumference evenly distributed, the one end of screw rod directly links firmly with the pump head through the screw thread, the other end passes through the nut and links to each other with the fixed plate.
In the above-described impact-resistant precision multistage centrifugal pump, the screw passes through the flange face of the motor and the nut for fastening is located above the flange face.
In the impact-resistant precision multistage centrifugal pump, the bottom surface of the fixing plate is welded with a plurality of pull rings for locking with the ground.
Compared with the prior art, this centrifugal pump is used for fixed pipeline through set up the fixed plate between motor and pump head, makes the pipeline can not take place because the flange face fracture that the impact caused to increase holistic tightness through the screw rod, make locking between fixed plate and the ground with the pull ring again, wholly can not produce the slope, have overall structure more firm, the advantage of the difficult fracture of pipeline.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, this anti-impact precision type multistage centrifugal pump, including motor 1 and the pump head 2 of the vertical setting of mutually supporting, support through stand 3 between motor 1 and the pump head 2 and connect, its pump shaft passes from stand 3 center and is connected with pump head 2, be horizontal fixed plate 4 through screwed connection between stand 3 and the motor 1 flange face, the delivery port department of pump head 2 is connected with pipeline 5, pipeline 5 bends and makes the opening up and pass fixed plate 4 and link to each other with fixed plate 4 through stay 6.
Further saying in detail, because pump head 2 position is higher apart from fixed plate 4, in order to increase holistic fastening nature, vertically between fixed plate 4 and pump head 2 be provided with a plurality of screws 7, screws 7 are circumference evenly distributed, and screw 7's one end directly links firmly with pump head 2 through the screw thread, and the other end passes through the nut and links to each other with fixed plate 4.
Further, the screw 7 penetrates through a flange face of the motor 1 and a nut for fastening is located above the flange face, and the screw 7 penetrates through the flange face of the motor 1 while being connected with the pump head 2, so that the motor 1, the fixing plate 4 and the pump head 2 are integrated.
Furthermore, a plurality of pull rings 8 for locking with the ground are welded on the bottom surface of the fixing plate 4, and the components for locking comprise springs or steel wires.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
Although the terms motor 1, pump head 2, column 3, fixing plate 4, tube 5, locking tab 6, screw 7, pull ring 8, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
