Detailed Description

The technical solution and other advantages of the present invention will become apparent from the following detailed description of specific embodiments of the present invention, which is to be read in connection with the accompanying drawings. It is to be understood that the drawings are provided solely for the purposes of reference and illustration and are not intended as a definition of the limits of the utility model. The dimensions shown in the figures are for clarity of description only and are not to be taken in a limiting sense.

Referring to fig. 1, a submersible pump 100 according to an embodiment of the present invention includes a flow channel 10, and the submersible pump 100 is used for pumping a liquid, such as irrigation water, through the flow channel 10 to a desired lift to meet various requirements.

The flow channel 10 comprises an inlet 11 and an outlet 13, and the inner wall of the flow channel 10 is fixedly provided with a helical blade 15. The high-pressure gas A and the liquid realize gas-water mixing along the helical blade 15 in the flow channel 10 and realize water pumping at the outlet 13 of the flow channel.

Specifically, the high-pressure gas a and the normal-pressure liquid enter the flow channel 10 from the inlet 11 of the flow channel 10, are guided by the helical blade 15, and form a vortex force around the helical blade 15 under the action of centrifugal force, along the helical blade 15, the high-pressure gas a and the normal-pressure liquid are gradually pressurized and are ejected from the outlet 13, and the submersible pump 100 forms pump water. The spiral blade 15 is used for guiding high-pressure gas and liquid, extending the gas-water mixing path of the high-pressure gas and the liquid, enabling the high-pressure gas and the liquid to be fully mixed, forming vortex force around the spiral blade 15, and enabling the high-pressure gas to be gradually pressurized with the liquid under the action of high-speed rotation, and then being sprayed out from the outlet 13.

In addition, since the high-pressure gas and the liquid are guided by the spiral blade 15 under the centrifugal force, the flow channel 10 forms a low pressure region having neither gas nor liquid at the approximate center of the cross section of the starting end of the spiral blade 15, so that the liquid around the inlet 11 of the flow channel 10 is sucked into the flow channel 10 under the atmospheric pressure, and thus, the liquid is continuously sucked into the flow channel 10 and is pumped out along the spiral blade 15 to the outlet 13 of the flow channel 10 at a high speed. It can be understood that, as shown in fig. 1, in order to increase the vortex force for gas-water mixing in the flow passage, the inner diameter of the flow passage 10 is gradually decreased from the inlet 11 to the outlet 13 of the flow passage 10. Alternatively, the pitch of the helical blade 15 in the direction from the inlet 11 to the outlet 13 of the flow channel 10 may also gradually decrease, i.e., the pitch of the helical blade 15 at the inlet 11 is greater than the pitch of the helical blade 15 at the outlet 13.

The flow path 10 and the helical blade 15 are integrally formed, and different combinations of parts may be used.

As shown in fig. 2 and 3, the spiral blade 15 may be a single-blade spiral arranged on the inner wall of the flow channel 10, when the high-pressure gas and the liquid enter the flow channel 10 from the inlet 11, the liquid is driven by the high-pressure gas to generate a centrifugal force along the spiral blade 15, so that the liquid is driven by the high-pressure gas to flow to the outlet 13 and realize water pumping, and in this process, the high-pressure gas and the liquid are mixed.

In this embodiment, since the high-pressure gas and the liquid are guided by the spiral blade 15 under the action of the centrifugal force, a vacuum low-pressure region is formed at the center of the flow channel 10 at the starting end of the spiral blade 15, and the liquid flows into the inlet 11 of the flow channel under the action of the atmospheric pressure, thereby completing the water absorption process. Because the helical blade 15 is fixed in the using process, the helical blade 15 and the submersible pump 100 are fixed into a whole, the driving of a motor is not needed, and the energy is saved. In addition, due to the increased path of the helical blade 15, the high-pressure gas and the liquid are fully mixed in the flow channel 10, and the lift of the liquid at the outlet 13 is increased under the action of centrifugal force. Meanwhile, when impurities such as sand and stones exist in the liquid, compared with the existing submersible pump, the spiral blade 15 is not easily abraded by the impurities, the maintenance is simple, the manufacturing cost is low, the service life of the submersible pump is prolonged, and the service environment of the submersible pump is widened.

It can be understood that, in the present embodiment, the volume ratio of the high-pressure gas to the liquid in the flow channel 10 can be changed according to the requirement of the lift, so as to meet different lift requirements. Preferably, the volume ratio of the high-pressure gas to the liquid in the flow channel 10 can be 2 to 3, so that the liquid can be pumped sufficiently when a sufficiently high head is achieved. In addition, runners with different screw pitches can be adopted, so that different lifts of pumped liquid are realized, and actual requirements are met.

The helical blade 15 in the flow channel 10 may be a single blade or three helical blades, as shown in fig. 4, the three helical blades 15 are uniformly distributed on the inner wall of the flow channel 15. It is understood that the number of the helical blades 15 can be set according to the requirement, and is not limited to one or three in the present embodiment.

In the present embodiment, the high-pressure gas a may be generated by applying work to the air by using one or more green energy sources, such as water energy, wind energy, solar energy, etc., and then delivered to the inlet 11 of the flow channel 10, for example, a supercharger may be used to convert the green energy sources.

The submersible pump of the utility model utilizes the helical blade 15 fixedly arranged in the flow channel to ensure that high-pressure gas and liquid form a vacuum low-pressure area at the central position of the flow channel at the starting end of the helical blade under the action of centrifugal force, and then the liquid can continuously flow into the inlet 11 of the flow channel under the action of atmospheric pressure. In addition, helical blade 15 has prolonged the route that the gas water mixes for high-pressure gas and ordinary pressure liquid are rationally mixed, need not to change the length of runner 10, have improved the lift.

As described above, it will be apparent to those skilled in the art that other various changes and modifications may be made based on the technical solution and concept of the present invention, and all such changes and modifications are intended to fall within the scope of the appended claims.
