Description

Technical Field

[0001] The utility model relates to the technical field of self-priming pumps, and more specifically, to an energy-saving horizontal self-priming pump. Background Art

[0002] The energy-saving horizontal self-priming pump is a new type of pump independently developed and produced. It is a self-priming centrifugal pump with the advantages of compact structure, easy operation and maintenance, balanced operation, convenient maintenance, high efficiency, long life, and strong self-priming ability. No foot valve is required in the pipeline. Before operation, it is sufficient to keep a fixed amount of liquid in the pump body. This simplifies the piping system and improves working conditions. Self-priming pumps play an important role in the paint production process, for example, when it is necessary to transfer liquid from a closed container or a low-level to a higher level.

[0003] For example, the patent of prior art announcement number CN213419378U discloses a water-free horizontal self-priming pump, including a self-priming pump, a motor, an outlet pipeline, an inlet pipeline and an exhaust valve, and the input end of the self-priming pump is connected to the output shaft of the motor; the pump casing of the self-priming pump is respectively provided with a liquid outlet, a liquid inlet and a water injection hole, the pump casing of the self-priming pump corresponding to the liquid outlet position is provided with an outlet pipeline, and the pump casing of the self-priming pump corresponding to the liquid inlet position is provided with an inlet pipeline, and an exhaust valve is provided on the inlet pipeline. During use, the exhaust valve is provided instead of the check valve to avoid the problem of the need to inject water each time the pump is started due to the siphon phenomenon and the backflow of liquid in the pump chamber due to the siphon phenomenon; when the pump is stopped, the exhaust valve is opened, and air enters the inlet pipeline to quickly isolate the co-flowing medium in the inlet pipeline.

[0004] The above device is easy to use when working. By setting the exhaust valve and removing the check valve, the liquid in the pump chamber is prevented from flowing back due to siphoning, which causes the problem of needing to inject water every time the pump is started. It is fast, efficient and reliable. However, when it is restarted after shutdown, the water inside the pump body is prone to backflow, and water needs to be injected into the pump body again, which is a cumbersome operation. Utility Model Content

The technical problem to be solved by the present invention is: how to avoid adding water flow into the pump body when the pump body is stopped and restarted.

[0008] In a preferred embodiment, a mounting lug is provided on the lower side of the outer end surface of the drive motor, and the output shaft of the drive motor passes through one side of the pump body and extends into the interior of the pump body;

[0009] The output shaft of the driving motor is provided with a rotating support disk inside the pump body, an outer end surface of one side of the rotating support disk is provided with a guide plate, and an outer side of one end of the guide plate is provided with an annular support plate.

[0010] In a preferred embodiment, a mounting base is provided on the lower side of the outer end surface of the pump body, a first connecting flange is provided on the outer side of the upper end of the water outlet pipe, and second connecting flanges are provided at both ends of the flow guide member;

[0011] A concave sealing groove is provided on the upper end surface of the first connecting flange, and a sealing protrusion is provided on one side of the outer end of the second connecting flange.

[0012] In a preferred embodiment, the upper ends of the mounting ear plate and the mounting base plate are provided with locking bolts, and the outer end surfaces of the first connecting flange and the second connecting flange in a top view are arranged in a coplanar state;

At the same time, under the corresponding setting of the concave sealing groove and the sealing protrusion, the sealing performance of the guide member installation can be effectively increased.

There are two mounting ear plates 3, which are mirror-imaged on both sides of the vertical center axis of the mounting base 1 in a top-down direction. The lower side of the inner end surface of the guide member 8 is concave.

[0028] like Figure 3 and 4 As shown, a water outlet pipe 11 is provided on the upper side of the outer end surface of the pump body 5, a flow guide 8 is provided on the outside of the upper end of the water outlet pipe 11, a transverse support rod 17 is provided in the middle of the inner end surface of the flow guide 8, an annular sliding sleeve 18 is provided in the middle of the inner end surface of the transverse support rod 17, and a vertical support sliding rod 19 is provided inside the annular sliding sleeve 18;

[0029] A sealing slider 20 is provided at the lower end of the vertical support slide bar 19, and a support spring 21 is provided on the outer end surface of the vertical support slide bar 19 on the lower side of the annular sleeve 18. The support spring 21 can support the sealing slider 20 so that the sealing slider 20 seals the lower end of the guide member 8, thereby preventing water from flowing back inside the pump body 5. When continuing to work, there is no need to inject water into the pump body 5, thereby increasing the working efficiency of the pump body 5. The output shaft of the drive motor 2 is provided with a rotating support disk 13 inside the pump body 5, and the outer end surface of one side of the rotating support disk 13 is provided with a guide plate 10, and the outer side of one end of the guide plate 10 is provided with an annular support plate 9;

[0030] A first connecting flange 12 is provided on the outside of the upper end of the water outlet pipe 11, and a second connecting flange 16 is provided at both ends of the flow guide 8.

[0033] Working principle of this utility model:

[0034] When the present invention is in use, the staff controls the driving motor 2 to work, and the driving motor 2 will drive the rotating support disk 13 to rotate through the output shaft, and then the external water flow can be introduced into the interior of the pump body 5 from the water inlet pipe 7, and then discharged from the water outlet pipe 11. The water flow in the pump body 5 will generate a large pressure, thereby supporting the sealing slider 20, causing the sealing slider 20 to slide upward, thereby guiding the water flow from the guide member 8 to the outside, and then when the driving motor 2 stops working, the support spring 21 will support the sealing slider 20, causing it to slide downward, thereby causing the sealing slider 20 to fit on the lower side of the inner end surface of the guide member 8, thereby avoiding water backflow inside the pump body 5. When the pump body 5 is working, there is no need to inject water into the pump body 5, which can effectively increase the working efficiency of the pump body 5.
