Description

Centrifugal pump body

Technical Field

The utility model belongs to the technical field of pump body processing, and relates to a pump body, in particular to a centrifugal pump body.

Background

The pump is a general-purpose machine and has wide application. With the development and evolution of water pumps, various water pumps are provided, the names of the water pumps are eight-flower, the calling methods and the classification of the water pumps are different in various water pump books, centrifugal submersible pumps are one type of the centrifugal submersible pumps and mainly comprise pump shells, impellers, pump shafts, pump racks and the like, the pumps are filled with water before starting, the impellers rotating after starting drive the water in the pumps to rotate at high speed, and the water is centrifugally moved, thrown out and pressed into a water outlet pipe. After the water is thrown out, the pressure near the impeller is reduced, and a low-pressure area is formed near the rotating shaft. The pressure is much lower than the atmospheric pressure, the outside water under the action of the atmospheric pressure, the bottom valve is opened, the water enters the pump from the water inlet pipe, and the water is thrown out again in high-speed rotation along with the impeller and is pressed into the water outlet pipe. The impeller is driven by the power machine to rotate at a high speed continuously, and water is continuously pumped from a low position to a high position.

However, when the water outlet of the existing centrifugal pump body is installed with the water pipe, the water outlet is not provided with a limiting structure, so that the installation depth of the water pipe is often too deep, water at the water inlet cannot enter, and the work efficiency of the centrifugal pump is seriously affected.

Disclosure of Invention

The utility model aims to solve the problems in the prior art by providing a centrifugal pump body.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides a centrifugal pump body, its characterized in that, is including the pump body main part that is the integrated into one piece structure setting, pump body main part on have the water inlet that is connected with the water pipe, the pump body in be located water inlet department and have the cushion chamber that supplies water and flow the buffering, be located cushion chamber bottom on offer the open slot that supplies water and flow to enter into the cavity, be located cushion chamber bottom central part the bellying that makes progress the arch and be used for rivers buffering has, cushion chamber and water inlet be linked together, and follow the bellying periphery wall on be equipped with a plurality of and be used for preventing the too dark stopper of water pipe assembly.

In the centrifugal pump body, the number of the limiting blocks is 3, the limiting blocks are arranged in the circumferential direction in sequence, and the heights of the limiting blocks are lower than the water inlet.

In foretell a centrifugal pump body, the transversal circular structural design of personally submitting of bellying, just bellying external diameter water inlet internal diameter equals, the bellying periphery wall on seted up the inverse circular arc that has the buffering drainage effect.

In the above centrifugal pump body, the inner peripheral wall of the water inlet is provided with an internal thread connected with the water pipe.

Compared with the prior art, this centrifugal pump body structural design is reasonable, can effectually prevent that the installation depth is too dark when the water pipe installation leads to not having advanced the problem of water, great improvement centrifugal pump work efficiency, extension its life.

In the figure, 1, a pump body; 2. a water inlet; 3. a buffer chamber; 4. an open slot; 5. a boss portion; 6. a limiting block; 7. an internal thread; 8. and (4) chamfering.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As in fig. 1, fig. 2, fig. 3 shows, this centrifugal pump body, including the pump body main part 1 that is the setting of integrated into one piece structure, pump body main part 1 is last to have the water inlet 2 that is connected with the water pipe, it has the cushion chamber 3 that supplies water stream buffering to lie in water inlet 2 department in the pump body, lie in and offer the open slot 4 that supplies water stream entering cavity on 3 bottoms in cushion chamber, it has the bellying 5 that makes progress arch and be used for the rivers buffering to lie in 3 bottoms central parts in cushion chamber, cushion chamber 3 is linked together with water inlet 2, and be equipped with a plurality of along 5 periphery walls of bellying and be used for preventing water pipe assembly too

dark stopper

6, 6 quantity of a plurality of stopper is 3, stopper 6 is the circumferencial direction setting in proper order, and stopper 6 highly all is less than water inlet 2 departments.

Principle of operation

When pump body water inlet 2 department needs to be connected with external water pipe, often because the water pipe inserts deeply, therefore the circulation of rivers effect is not good, this structure is located pump body water inlet 2 department and is provided with cushion chamber 3, a function that is used for rivers to get into and plays the buffering in the pump body, and be located and be provided with bellying 5 on the 3 bodies of cushion chamber, and be located and have inverted circular arc 8 on the 5 periphery walls of bellying, the effect that has the drainage, it is provided with 3 stopper 6 to be the circumferencial direction on the bellying 5 simultaneously, connect to this part when the water pipe and will unable continuation pipe connector, the circulation of rivers space is ensured, centrifugal pump's work efficiency has not only been improved, and service life is also prolonged.

Further saying in detail, the transversal circular structural design that personally submits of bellying 5, and 2 internal diameters of 5 external diameters water inlets of bellying equal, offered the radius arc 8 that has buffering drainage effect on the 5 periphery walls of bellying.

In more detail, the inner circumferential wall of the water inlet 2 is provided with an internal thread 7 connected with the water pipe.

The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
