Description

Technical Field

[0001] The invention belongs to the technical field of pump equipment, and in particular relates to an energy-saving pump. Background Art

[0002] A pump is a mechanical device that transports fluid or pressurizes fluid. It transfers the mechanical energy of the prime mover or other external energy to the fluid to increase the energy of the fluid. It is mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] As a machine that lifts, transports or increases the pressure of liquids, a water pump is an indispensable equipment in the fields of industry, agriculture, and life.

[0004] At present, most of the water pumps on the market use motors to drive the impeller inside the pump body to rotate at high speed. The centrifugal force generated forces the liquid to be thrown out from the edge of the pump body. In this process, the speed of the liquid increases. Since the blades are continuously impacted by the liquid, it is easy to cause the high-speed rotating impeller to shake, which will affect the rotation of the impeller. At the same time, when most water pumps are working, the internal liquid directly impacts the impeller, which can easily cause damage to the impeller and reduce the efficiency of conveying liquid.

[0005] In view of this, a new type of energy-saving pump is needed to solve the problems existing in the above-mentioned water pumps. Summary of the invention

[0006] The invention provides an energy-saving pump, which can effectively solve the problems of easy damage of the impeller and low efficiency of conveying fluid in the existing water pump during operation.

[0007] The technical solution of the present invention to solve the technical problem is as follows:

[0008] According to one aspect of the present invention, there is provided an energy-saving pump, characterized in that it comprises a driving motor, a coupling, a pump body and a water inlet pipe which are detachably connected in sequence, the pump body being provided with a water outlet, the outer end of the water inlet pipe being the water inlet, a rotating shaft being axially rotated together inside the water inlet pipe, the pump body and the coupling, the output end of the driving motor being connected to one end of the rotating shaft, an impeller and a second spiral blade being fixedly provided on the outer side of the rotating shaft at the positions of the pump body and the water inlet pipe, respectively, a plurality of first blades being symmetrically fixedly provided on the side of the impeller corresponding to the water inlet pipe with the rotating shaft as the symmetry point, the first blades being arc-shaped, and the height decreasing from the side close to the rotating shaft to the side close to the edge of the impeller.

[0009] Furthermore, a support assembly is detachably mounted on the outside of the water inlet pipe, and the support assembly includes a support seat and a plurality of fixing hoops for fixing the water inlet pipe, and the support seat and the fixing hoops are fixed by bolts.

[0010] Furthermore, a connecting component for supporting the rotation of the rotating shaft is provided on the inner side of the water inlet of the water inlet pipe end, and the connecting component includes a stabilizing frame, which is installed in the water inlet in a trident shape, and the center of the stabilizing frame is rotatably connected to the end of the rotating shaft through a bearing; the connection between the coupling and the pump body is rotatably connected to the rotating shaft through a bearing.

[0011] Furthermore, the impeller is in the shape of a round pancake, and its two side surfaces are convex.

[0012] Furthermore, each of the first blades on the impeller is located at the center of the pump body.

[0013] Furthermore, the pump body and the water inlet pipe are fixed and sealed by bolts, and the opening at the connection between the pump body and the water inlet pipe is larger than the outer diameter of the impeller.

[0014] Furthermore, the outer diameter of the second blade is close to the inner diameter of the water inlet pipe.

[0015] Furthermore, a sealing plug is installed at the lowest position below the pump body, and the sealing plug is threadedly connected to the pump body.

[0016] Furthermore, the outer shape of the sealing plug end is adapted to the inner shape of the pump body.

[0017] Compared with the prior art, the energy-saving pump described in the present invention has the following beneficial effects:

[0018] (1) The energy-saving pump of the present invention is provided with an impeller in the pump body. The impeller is in the shape of a round pancake, and the two side surfaces of the impeller are convex. This enables the center of the impeller to withstand a higher impact force, and the impeller itself has a higher strength. It is not easy to vibrate when the impeller rotates, which effectively avoids the waste of work done by the impeller and also reflects the energy saving of the water pump.

[0019] (2) The present invention arranges a second spiral blade in the water inlet pipe. The second blade and the impeller are located on the same rotating shaft, which can increase the head of the water pump, thereby improving the water pump delivery efficiency, reflecting the energy-saving and high efficiency of the water pump. At the same time, due to the presence of the second blade, the liquid in the water pipe will not directly act on the impeller, further increasing the working safety of the impeller.

[0020] (3) The present invention also has a sealing plug installed on the pump body, and the water in the pump body can be easily discharged by disassembling and assembling the sealing plug, so that the inside of the pump body can be easily cleaned.

[0021] (4) The present invention greatly facilitates the installation of the water pump by providing a support assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] When the energy-saving pump is in use, the water inlet 8 on the water inlet pipe 5 and the water outlet 4 on the pump body 3 are connected to the external water pipes respectively, the driving motor 1 is started, and the liquid enters the water inlet pipe 5 from the water inlet 8. At this time, the spiral second blade 14 is in a rotating state, and the water is transported to the pump body 3. The impeller 11 in the pump body 3 rotates synchronously, and the liquid is thrown to the inner edge of the pump body 3 through the first blade 12. As the pressure increases, the liquid will be discharged from the water outlet 4; in the above-mentioned liquid transportation process, the liquid transportation impact will be alleviated by the second blade 14. Under the action of the second blade 14, the working state of the impeller 11 can be guaranteed to be stable, and the shape and structure design of the impeller 11 can make it more stable, so as to ensure energy-saving and efficient transportation.

[0031] In this embodiment, in order to facilitate the installation of the energy-saving pump, a support assembly is detachably installed on the outside of the water inlet pipe 5.

It is best if the second blade 14 is about 10 mm away from the inner side of the water inlet pipe 5, which can increase the head of the water pump and improve the transportation efficiency.

The sealing plug 13 is threadedly connected to the pump body 3, which is convenient for disassembly and assembly of the sealing plug 13, and the sealing plug 13 and the pump body 3 are tightly sealed to prevent liquid leakage. As a preferred embodiment, the shape of the end of the sealing plug 13 is the same as the internal shape of the pump body 3, which can ensure the integrity of the interior of the pump body 3 and avoid affecting the flow of liquid.
