Description

Technical Field

[0001] The present invention relates to the technical field of water circulation, and in particular to a water circulation energy-saving boosting device. Background Art

[0002] Circulating water pumps can provide power for the circulating water systems of large central air conditioners, centralized heating circulation systems, and water circulation in industrial cooling circulation systems. Generally speaking, the greater the power of the circulating water pump, the greater the flow rate and the higher the head, and the higher the energy consumption of the circulating water pump.

[0003] In order to respond to the national advocacy of energy conservation and environmental protection, and to increase the head of water circulation without increasing the power of the circulating water pump, Chinese invention patent CN205190135U discloses a one-piece fluid boosting circulating water pump, which is connected to a fluid booster. The fluid booster mainly includes a first-stage boosting chamber, a second-stage boosting chamber and a third-stage boosting chamber arranged from the inside to the outside. Water holes are respectively provided between the first-stage boosting chamber and the second-stage boosting chamber, and between the second-stage boosting chamber and the third-stage boosting chamber. After multi-stage boosting, the fluid is ejected from the injection port to achieve the purpose of multi-stage boosting. The increased pressure kinetic energy can replace part of the head, thereby increasing the head of the system water circulation without increasing the power of the circulating water pump, thereby achieving the purpose of energy conservation and environmental protection.

[0004] However, although the fluid booster is designed with first-stage, second-stage and third-stage boosting chambers, the amount of water entering the third-stage boosting chamber is relatively small, and the boosting effect of the third-stage boosting chamber is negligible, so the boosting effect of the entire system is unsatisfactory. Summary of the Invention

[0005] In view of the defects in the prior art, the present invention provides a water circulation energy-saving boosting device to improve the boosting effect and further increase the head of the circulating water pump.

[0006] The present invention provides a water circulation energy-saving boosting device, comprising a housing, a first-stage boosting chamber, a second-stage boosting chamber, and a third-stage boosting chamber sequentially arranged in the housing from the inside to the outside, and an upper flange and a lower flange respectively arranged at both ends of the housing;

[0007] The first-stage booster chamber includes a water absorption chamber and a drainage chamber. The water absorption chamber is a tapered structure with a gradually decreasing diameter from bottom to top. The lower end of the drainage chamber is connected to the upper end of the water absorption chamber.

[0008] The secondary boosting chamber is arranged on the outside of the drainage chamber, and the tertiary boosting chamber is arranged on the outside of the secondary boosting chamber. A water flow transition chamber is also provided on the outside of the drainage chamber and is located below the secondary boosting chamber and the tertiary boosting chamber. The water absorption chamber is connected to the water flow transition chamber through an injection ring hole. The lower end of the secondary boosting chamber is connected to the water flow transition chamber. The lower end of the tertiary boosting chamber is connected to the water flow transition chamber through a primary injection hole. The upper part of the tertiary boosting chamber is connected to the secondary boosting chamber through a secondary injection hole. The upper end of the secondary boosting chamber is provided with a tertiary injection hole.

[0009] Furthermore, the injection ring hole faces obliquely upward and is a tapered ring hole with a wide inlet end and a narrow outlet end.

[0010] Furthermore, the first-level injection hole faces upward and is a tapered hole with a wide inlet end and a narrow outlet end.

[0011] Furthermore, the secondary injection hole faces obliquely upward and is a tapered hole with a wide inlet end and a narrow outlet end.

[0012] Furthermore, the three-stage injection hole includes a tapered hole section whose diameter gradually decreases from bottom to top and a straight hole section connected to the upper end of the tapered hole section.

[0013] Furthermore, the upper end of the secondary boost chamber is sealed by a spray hole ring, and the tertiary spray hole is opened on the spray hole ring.

[0014] Furthermore, the bottom wall of the water flow transition chamber is inclined upwardly and outwardly, and the top wall of the water flow transition chamber is inclined upwardly and inwardly, and the bottom wall and the top wall of the water flow transition chamber are transitioned through an arc surface.

[0015] Furthermore, a water retaining convex ring is provided on the inner wall outside the secondary boost chamber below the secondary injection hole, and the water retaining convex ring has an arcuate ring segment and a straight ring segment. The lower end of the arcuate ring segment is connected to the inner wall outside the secondary boost chamber and smoothly transitions with the top wall of the water flow transition chamber, and the straight ring segment extends upward from the upper end of the arcuate ring segment.

[0016] The beneficial effects of the present invention are embodied in:

[0017] The water circulation energy-saving booster device provided by the present application is installed at the water outlet of the circulating water pump. The load pressure generated by the circulating water pump when working pushes the water into the water suction chamber of the booster device, and pressurizes the water through the water suction chamber with a conical structure. A part of the pressurized water passes through the drainage chamber and is sprayed out from its upper end, so that a negative pressure is generated around the upper end of the drainage chamber. The other part of the pressurized water is sucked into the water flow transition chamber from the injection ring hole under the action of the negative pressure. A part of the water sucked into the water flow transition chamber enters the secondary booster chamber, and the other part is sprayed into the tertiary booster chamber through the primary injection hole, and then sprayed out through the secondary injection hole. The water enters the secondary boosting chamber, and the water pressurized by the tertiary boosting chamber mixes with the water in the secondary boosting chamber, and is finally ejected through the tertiary injection hole at the upper end of the secondary boosting chamber. The water ejected from the drainage chamber and the upper end of the secondary boosting chamber merge into a high-density fluid. The pressure shock wave generated in an instant converts the effective pressure into kinetic energy, so that the pressure increased by the device replaces part of the head of the circulating water pump. In this way, the head of the original circulating water pump can be reduced while maintaining the inconvenience of the circulating flow rate of the conventional design, and the power of the motor equipped with the circulating water pump can be greatly reduced, thereby achieving the goal of energy saving.

[0018] In the present application, water flows upward through a water flow transition chamber below the secondary boosting chamber and the tertiary boosting chamber, so that the water flows vertically upward into the secondary boosting chamber and the tertiary boosting chamber. This is beneficial to increase the amount of water entering the tertiary boosting chamber, thereby improving the pressurization effect of the tertiary boosting chamber on the water flow, thereby further improving the head of the circulating water pump.

DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a water circulation energy-saving boosting device, including a shell 100, a first-stage boosting chamber 200, a second-stage boosting chamber 300 and a third-stage boosting chamber 400 arranged in the shell 100 from the inside to the outside, and an upper flange 110 and a lower flange 120 respectively arranged at both ends of the shell 100.

[0025] The first-stage booster chamber 200 includes a water suction chamber 210 and a drainage chamber 220 . The water suction chamber 210 is a tapered structure with a diameter gradually decreasing from bottom to top. The lower end of the drainage chamber 220 is connected to the upper end of the water suction chamber 210 .

[0026] The secondary boost chamber 300 is arranged outside the drainage chamber 220, and the tertiary boost chamber 400 is arranged outside the secondary boost chamber 300. A water flow transition chamber 500 is also arranged outside the drainage chamber 220 and is located below the secondary boost chamber 300 and the tertiary boost chamber 400.

[0027] The water absorption chamber 210 is connected to the water flow transition chamber 500 through the injection ring hole 230. Specifically, the injection ring hole 230 faces obliquely upward and is a tapered ring hole with a wide inlet end and a narrow outlet end. The injection ring hole 230 faces obliquely upward so that the injection ring hole 230 can inject water obliquely upward. The injection ring hole 230 is a tapered ring hole with a wide inlet end and a narrow outlet end, which can increase the injection water pressure.

[0028] The lower end of the secondary boost chamber 300 is connected to the water flow transition chamber 500, and the lower end of the tertiary boost chamber 400 is connected to the water flow transition chamber 500 through the primary injection hole 410. Specifically, the primary injection hole 410 faces upward and is a tapered hole with a wide inlet end and a narrow outlet end. The primary injection hole 410 faces obliquely upward, so that the primary injection hole 410 can spray water upward. The primary injection hole 410 is a tapered hole with a wide inlet end and a narrow outlet end, which can increase the injection water pressure.

[0029] The upper part of the tertiary boost chamber 400 is connected to the secondary boost chamber 300 through the secondary injection hole 420. The secondary injection hole 420 faces obliquely upward and is a tapered hole with a wide inlet end and a narrow outlet end. Similarly, the secondary injection hole 420 faces upward, which allows the secondary injection hole 420 to spray water obliquely upward. The secondary injection hole 420 is a tapered hole with a wide inlet end and a narrow outlet end, which can increase the injection water pressure.

[0030] The upper end of the secondary plenum chamber 300 is provided with a tertiary injection hole 310. Specifically, the tertiary injection hole 310 comprises a tapered hole section 311, which tapers from bottom to top, and a straight hole section 312 connected to the upper end of the tapered hole section 311. The tapered hole section 311 of the tertiary injection hole 310 increases the injection water pressure, while the straight hole section 312 serves to confine the flow. To facilitate manufacturing, the upper end of the secondary plenum chamber 300 is sealed by an injection hole ring 313, on which the tertiary injection hole 310 is located.

[0031] The water circulation energy-saving booster device provided by the present application is installed at the water outlet end of the circulating water pump. The load pressure generated by the circulating water pump when working pushes the water to the water suction chamber 210 of the booster device, and pressurizes the water through the conical structure of the water suction chamber 210. A part of the pressurized water passes through the drainage chamber 220 and is sprayed out from its upper end, so that a negative pressure is generated around the upper end of the drainage chamber 220. The other part of the pressurized water is sucked into the water flow transition chamber 500 from the injection ring hole 230 under the action of the negative pressure. A part of the water sucked into the water flow transition chamber 500 enters the secondary booster chamber 300, and the other part is sprayed into the tertiary booster chamber 400 through the primary injection hole 410, and then passes through the secondary injection hole 410. The perforations 420 are sprayed into the secondary boosting chamber 300. The water pressurized by the tertiary boosting chamber 400 is mixed with the water in the secondary boosting chamber 300 and finally ejected through the tertiary injection holes 310 at the upper end of the secondary boosting chamber 300. The water ejected from the drainage chamber 220 and the upper end of the secondary boosting chamber 300 merge into a high-density fluid. The pressure shock wave generated in an instant converts the effective pressure into kinetic energy, so that the pressure increased by the device replaces part of the head of the circulating water pump. In this way, the head of the original circulating water pump can be reduced while maintaining the inconvenience of the circulating flow rate of the conventional design. The power of the motor equipped with the circulating water pump can be greatly reduced, thereby achieving the goal of energy saving.

[0032] In the present application, the water flow transition chamber 500 is located below the secondary boost chamber 300 and the tertiary boost chamber 400, and the water flow flows upward through the water flow transition chamber 500, so that the water flow rushes vertically upward into the secondary boost chamber 300 and the tertiary boost chamber 400, which is conducive to increasing the amount of water entering the tertiary boost chamber 400, thereby improving the pressurization effect of the tertiary boost chamber 400 on the water flow, thereby further improving the head of the circulating water pump.

[0033] In a preferred embodiment, the bottom wall 510 of the water flow transition chamber 500 is inclined upwardly and outwardly, and the top wall 520 of the water flow transition chamber 500 is inclined upwardly and inwardly. The bottom wall 510 and the top wall 520 of the water flow transition chamber 500 are transitioned by an arc surface 530. The water flow injected from the injection ring hole 230 first flows along the bottom wall 510 of the water flow transition chamber 500 in an oblique upward direction to the outside, turns near the arc surface 530, and then flows along the top wall 520 of the water flow transition chamber 500 in an oblique upward direction. When the water flows inside and along the top wall 520 of the water transition chamber 500, part of the water flow is distributed to enter the third-stage booster chamber 400, and the remaining water flow flows into the second-stage booster chamber 400. In this way, the bottom wall 510, the curved surface 530 and the top wall 520 of the water transition chamber 500 can guide the water flow, so that the water flow can flow smoothly into the second-stage booster chamber 300 and the third-stage booster chamber 400 respectively, thereby effectively preventing the water flow from generating turbulence in the water transition chamber 500 and reducing the resistance of the water flow.

[0034] More preferably, a water retaining convex ring 320 is provided on the inner wall outside the secondary boosting chamber 300 below the secondary injection hole 420. The water retaining convex ring 320 has an arcuate ring segment 321 and a straight ring segment 322. The lower end of the arcuate ring segment 321 is connected to the inner wall outside the secondary boosting chamber 300 and smoothly transitions with the top wall 520 of the water flow transition chamber 500. The straight ring segment 322 extends upward from the upper end of the arcuate ring segment 321. The water retaining convex ring 320 not only balances the water flow of the secondary boosting chamber 300 and the tertiary boosting chamber 400, but also accelerates and pressurizes the water flow passing therethrough. The arcuate ring segment 321 of the water retaining convex ring 320 is connected to the inner wall outside the secondary boosting chamber 300 and smoothly transitions with the top wall 520 of the water flow transition chamber 500, allowing the water flow to flow smoothly into the secondary boosting chamber 300, thereby reducing the resistance of the water flow.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
