Description

Technical Field

[0001] This utility model relates to the field of hydraulic module technology, specifically to an integrated circular top-mounted water pump hydraulic module. Background Technology

[0002] Existing cylindrical hydraulic modules typically use a top-bottom configuration, with the water tank on top and the support below. The weight of the water tank is usually greater than the weight of the support, causing the equipment to wobble and become unstable during operation, affecting its normal operation and lifespan. Furthermore, the electrical control components and piping assemblies are located at the bottom, making them susceptible to corrosion from leaks, increasing the risk of equipment failure. Limited installation space also necessitates a separate access panel, increasing the complexity of installation and maintenance. If the water pump in existing hydraulic modules is positioned at the top and the inner tank at the bottom, the internal expansion space of the module will be insufficient. When the liquid expands and contracts due to temperature changes, the limited expansion space can cause air to enter the water pump, leading to water shortage and pump burnout, thus affecting the normal operation of the system. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an integrated circular top-mounted water pump hydraulic module, which solves the problem of instability caused by defects in the existing hydraulic module's structure.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated circular top-mounted water pump hydraulic module, comprising an integrated outer shell, wherein the inner cavity of the outer shell is divided by a partition into a lower cavity for placing an inner liner and an upper cavity for placing a replenishment tank, and a water pump connected to the replenishment tank and the inner liner is also provided in the upper cavity.

[0005] The replenishment tank is provided with a first circulation pipe, and a second expansion space is formed inside the replenishment tank and above the first circulation pipe;

[0006] A second circulation pipe is provided below the side wall of the inner liner, and an overflow pipe is provided above the side wall. A first expansion space is formed inside the inner liner and above the overflow pipe.

[0007] Preferably, the integrated outer shell is a cylindrical hollow cylindrical structure with an upper end cap.

[0008] Preferably, the replenishment tank is provided with a first venting component, which penetrates the outer wall of the outer shell or the upper end cover.

[0009] Preferably, the first ventilation assembly includes a first bidirectional pressure relief valve disposed on the replenishment tank, and an exhaust pipe is connected to the top of the first bidirectional pressure relief valve, the exhaust pipe penetrating the outer wall of the housing.

[0010] Preferably, the first venting assembly includes a first bidirectional pressure relief valve disposed on the replenishment tank, the first bidirectional pressure relief valve penetrating the upper end cover.

[0011] Preferably, a second venting assembly, including an exhaust pipe, is provided above the overflow pipe, and a second bidirectional pressure relief valve is provided at the end of the exhaust pipe extending out of the outer casing.

[0012] Preferably, one end of the second circulation pipe is connected to a three-way injection valve, and the other two ends of the three-way injection valve are respectively connected to the circulation pipe and the injection pipe.

[0013] Preferably, a spare pipe is also provided on the side wall of the inner liner, and the spare pipe and the second circulation pipe are located at the same horizontal line.

[0014] Preferably, a one-way valve is provided at the end of the water pump that extends into the inner tank.

[0015] The beneficial effects of this utility model are as follows: By using the integrated circular top-mounted water pump hydraulic module provided by this utility model, compared with the prior art, the integrated shell with the inner tank located at the bottom and the replenishment tank and water pump located at the top makes the center of gravity of the equipment more stable. This effectively avoids the problems of instability and leakage-induced electrical control failures caused by the water tank being located at the top of traditional hydraulic modules. Furthermore, the top of the shell is equipped with a removable top cover instead of an inspection port and cover, providing more space for maintenance and installation, and resulting in a neat and aesthetically pleasing appearance, thus improving production efficiency. It also facilitates maintenance and installation, greatly improving work efficiency.

[0016] Meanwhile, a first expansion space is provided in the inner tank and a second expansion space is provided in the replenishment tank, providing sufficient expansion space for the liquid to heat up during operation, making the entire system more stable. The design of the two expansion spaces places the gas in the replenishment tank and inner tank at the top and the water at the bottom, ensuring pressure balance between the replenishment tank and inner tank, preventing gas from entering the water pump, maintaining system pressure balance, and ensuring the normal operation of the system.

[0023] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. This utility model discloses an integrated circular top-mounted water pump hydraulic module, comprising an integrated outer shell. The inner cavity of the outer shell is divided by a partition into a lower cavity for housing an inner tank and an upper cavity for housing a replenishment tank. A first circulation pipe is provided on the replenishment tank, and a second expansion space is formed inside the replenishment tank and above the first circulation pipe. A second circulation pipe is provided below the side wall of the inner tank, and an overflow pipe is provided above the side wall. A first expansion space is formed inside the inner tank and above the overflow pipe. The integrated outer shell, with the inner tank at the bottom and the replenishment tank and water pump at the top, makes the center of gravity of the device more stable, effectively avoiding the instability caused by the water tank being located at the top in traditional hydraulic modules and the electrical control failures caused by leakage. The first expansion space in the inner tank and the second expansion space in the replenishment tank provide sufficient expansion space for the operating liquid to heat up, making the entire system operate more stably.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0025] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0026] This application provides embodiments of a hydraulic module, such as... Figures 1 to 2 As shown, the hydraulic module is a one-piece shell 1, which is a cylindrical hollow structure with a metal powder-coated finish. In this embodiment, the cross-section is preferably circular. The one-piece shell 1 structure has no connecting gaps in appearance, has high overall integrity, and is clean, beautiful, and easy to process.

[0027] The outer casing 1 has an upper cover 6 on its top and feet on its bottom. The upper cover 6 is detachably connected to the outer casing 1 via a snap-fit ​​mechanism, allowing for a fully open top to facilitate the installation and maintenance of internal components, such as the replenishment tank 7 and water pump in the upper cavity 7. The outer casing 1 and upper cover 6 can be assembled online, saving labor and increasing production efficiency. The upper cover 6 replaces the existing inspection port and cover, reducing production costs.

[0028] Specifically, the inner cavity of the outer shell 1 is divided by a partition 2 into a lower cavity 4 for housing the inner tank and an upper cavity 3 for housing the replenishment tank 7. The inner tank is an enamel-lined pressurized water storage tank. The upper cavity also houses a water pump connected to the replenishment tank 7 and the inner tank, as well as electrical controls and piping. This layered design, with the inner tank containing the water located at the bottom and the replenishment tank 7 and water pump and other accessories located at the top, effectively avoids the problems of instability and leakage leading to electrical control failures caused by the water tank being located at the top in traditional hydraulic modules. Furthermore, the top of the outer shell 1 can be fully opened, providing more space for maintenance and installation, and making assembly and maintenance easier.

[0029] In this embodiment, a first circulation pipe 12 is provided on the replenishment tank 7, and a second expansion space 8 is formed inside the replenishment tank 7 and above the first circulation pipe 12. A second circulation pipe 16 is provided below the side wall of the inner tank, and an overflow pipe 15 is provided above the side wall. A first expansion space 5 is formed inside the inner tank and above the overflow pipe 15. Furthermore, a first venting component is provided on the replenishment tank 7, and a second venting component is provided above the overflow pipe 15. Due to the objective law of thermal expansion and contraction of liquids, if the hydraulic module discharges liquid during thermal expansion and venting, the liquid will gradually decrease while the gas will increase, potentially causing the water pump to ingest air. If the water pump ingests air, it will not operate normally. Therefore, in this embodiment, a first expansion space 5 is provided in the inner tank and a second expansion space 8 is provided in the replenishment tank 7 to provide sufficient expansion space when the operating liquid heats up. Conversely, if a negative pressure is formed, the two venting components automatically introduce air to ensure the pressure inside the replenishment tank 7 and the inner tank, making the entire system operate more stably. Furthermore, the design of the two expansion spaces places the gas in the replenishment tank 7 and the inner tank at the top, and the water at the bottom, which can ensure the pressure balance between the replenishment tank and the inner tank, prevent gas from entering the water pump, and ensure the normal operation of the system.

[0030] In this embodiment, the first venting assembly has two configuration methods: penetrating the outer wall of the outer casing 1 or penetrating the upper cover 6. Specifically, the form of penetrating the outer wall of the outer casing 1 is as follows: the first venting assembly includes a first bidirectional pressure relief valve 10 disposed on the replenishment tank 7, and an exhaust pipe 11 is connected to the top of the first bidirectional pressure relief valve 10, which penetrates the outer wall of the outer casing 1. This design effectively ensures the overall integrity of the upper cover 6, improves the aesthetic effect, and enhances the convenience of installing the upper cover 6. The form of penetrating the upper cover 6 is as follows: the first venting assembly includes a first bidirectional pressure relief valve 10 disposed on the replenishment tank 7, which penetrates the upper cover 6, reducing the need for an exhaust pipe 11 and allowing the first bidirectional pressure relief valve 10 to extend directly out of the upper cover 6 for direct replenishment and exhaust. The second venting assembly includes an exhaust pipe 13 connected to the first expansion space 5, and a second bidirectional pressure relief valve 14 is disposed at the end of the exhaust pipe 13 extending out of the outer casing 1.

[0031] The pressure of the first bidirectional pressure relief valve 10 is greater than the pressure of the second bidirectional pressure relief valve 14 installed on the exhaust pipe 13, forming a two-stage expansion protection for the hydraulic module. It automatically releases air when the set pressure is exceeded. If a negative pressure is formed at low temperatures, air can be added to the tank.

[0032] Furthermore, a spare pipe 19 is also provided on the side wall of the inner liner. The spare pipe 19 is a spare pipe for the second circulation pipe 16 and is located at the same horizontal line as the second circulation pipe 16.

[0033] Furthermore, in this embodiment, the hydraulic module is connected to the heat pump system, such as... Figure 3 and Figure 4 As shown, the heat pump system includes a radiator and a heat pump. The first circulation pipe 12, radiator, heat pump, second circulation pipe 16, inner tank, water pump 9, and replenishment tank 7 are connected in series to form a flow path. The liquid flows in two directions: a first flow direction and a second flow direction. The implementation with the liquid flowing in the first and second flow directions will be described in detail below.

[0034] For example, such as Figure 3 As shown, when the liquid flows in the first flow direction, the first circulation pipe 12 is the circulation inlet and the second circulation pipe 16 is the circulation outlet.

[0035] For example, such as Figure 4 As shown, when the liquid flows in the second flow direction, the second circulation pipe 16 is the circulation inlet, and the first circulation pipe 12 is the circulation outlet. It should be noted that when the liquid flows in the second flow direction, the water pump 9 is a self-priming pump, and a one-way valve 20 is installed at the end extending into the inner tank.

[0036] In addition, one end of a three-way injection valve 17 is connected to the second circulation pipe 16, and the other two ends of the three-way injection valve 17 are respectively connected to the circulation pipe and the injection pipe 18.

[0037] The injection pipe 18 is a pipe for introducing water into the flow path and is connected to an external water supply pipe. This embodiment also discloses a liquid supply method, specifically: during the initial water injection stage, the three-way injection valve 17 is rotated to the left and down position, the second bidirectional pressure relief valve 14 is opened, and circulating liquid is injected into the heat pump from the injection pipe 18, passing through the radiator and along the connected pipe to the first circulation pipe 12 into the replenishment tank 7. The circulating liquid then passes through the replenishment tank 7 and the water pump 9 into the inner tank. After the injection is completed, the three-way valve is rotated to the left and right position, and the injection pipe 18 is sealed with a nut.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
