Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a pump body cooling structure. Background Technology

[0002] A water pump is a device that extracts media. It typically relies on the rotation of an impeller to draw in and expel the media. There are many different types of water pumps depending on the working environment.

[0003] A submersible pump is a device used underwater. Its cooling is usually achieved by the water in contact with it. When a submersible pump needs to be used in a waterless environment, its internal motor is easily damaged because the temperature cannot be lowered. Therefore, when a submersible pump needs to pump media other than water, it is easily damaged, resulting in insufficient versatility. Utility Model Content

[0004] To address the problem that existing submersible pumps are easily damaged when pumping media other than water, and lack versatility, this application provides a pump body cooling structure, the specific solution of which is as follows.

The side of the inner shell near the pump impeller is used to connect to the pump body. A coolant flow channel is provided between the inner shell and the outer shell. After the inner shell is connected to the pump body, a coolant flow channel is also provided between the inner shell and the pump body. The coolant flow channels are interconnected and allow coolant to circulate.

[0006] By adopting the above technical solution, an outer shell and an inner shell are set up, and a coolant flow channel is formed between them and between the inner shell and the pump body. This allows the coolant to flow in the channel, thereby cooling the pump body. Even in a waterless environment, the cooling inside the pump body can still be guaranteed, thus improving its versatility.

[0007] Optionally, outer connecting plates are provided at both ends of the outer shell along its length. One side of the outer connecting plate is detachably connected to the outer shell, and the other side of the outer connecting plate is detachably connected to the pump body.

[0008] By adopting the above technical solution, outer connecting plates are provided at both ends of the outer shell, and the two sides of the outer connecting plates are detachably connected to the outer shell and the pump body respectively, which facilitates the installation and disassembly of the outer shell and the pump body, facilitates the assembly, maintenance and replacement of the pump body cooling structure, and also facilitates the injection and replacement of coolant.

[0009] Optionally, an inner connecting plate is provided on the side of the inner shell near the pump body impeller. One side of the inner connecting plate is detachably connected to the inner shell, and the other side of the inner connecting plate is detachably connected to the pump body.

[0010] By adopting the above technical solution, based on the existing cooling liquid flow channel formed by the outer shell and the inner shell to cool the pump body, the inner shell is detachably connected to the pump body through the inner connecting plate, which facilitates the installation and disassembly of the pump body cooling structure and is beneficial for subsequent maintenance and repair.

[0011] Optionally, the inner connecting plate is provided with an inner support member, one side of which is detachably connected to the inner connecting plate, and the other side of which is detachably connected to the pump body.

[0012] By adopting the above technical solution, an inner layer support is set on the inner layer connecting plate and is detachably connected to both the inner layer connecting plate and the pump body. This enhances the stability of the connection between the inner layer shell and the pump body, and also facilitates disassembly and maintenance.

[0013] Optionally, the inner support member has multiple water inlets.

[0014] By adopting the above technical solution, multiple water inlets are opened on the inner support component, which allows the coolant to flow more smoothly in the coolant channel and enhances the cooling effect of the pump body.

[0015] Optionally, the outer connecting plate is provided with an outer support member, one side of which is detachably connected to the outer connecting plate, and the other side of which is detachably connected to the pump body.

[0016] By adopting the above technical solution, on the basis of the pump body cooling structure composed of an outer shell, an inner shell, and a coolant flow channel, a detachable outer support is provided on the outer connecting plate for connection with the pump body, which enhances the stability of the connection between the outer connecting plate and the pump body, and makes the connection between the pump body cooling structure and the pump body more robust and reliable.

[0017] Optionally, the outer support member has multiple water inlets.

[0018] By adopting the above technical solution, multiple water inlets are opened on the outer support component, which allows the coolant to flow more smoothly in the coolant channel, enhances the flow efficiency of the coolant, and thus improves the cooling effect of the pump body cooling structure on the pump body.

[0019] Optionally, both the outer connecting plate and the inner connecting plate are provided with relief grooves, which allow the pump body's shaft to extend out.

[0020] By adopting the above technical solution, a clearance groove is opened on the outer connecting plate and the inner connecting plate to allow the pump body's rotating shaft to extend, which can avoid interference with the rotation of the pump body's rotating shaft and enable the pump body to operate normally.

[0021] Optionally, a rotating component is provided at the inner connecting plate. The inner side of the rotating component is used for fixed connection with the rotating shaft of the pump body, and the outer side of the rotating component is used for mounting blades.

[0022] By adopting the above technical solution, a rotating component is set at the inner connecting plate. The inner side of the rotating component is fixedly connected to the pump body shaft, and the outer side is equipped with blades. When the pump body shaft rotates, it can drive the blades to rotate, thereby accelerating the flow of coolant and improving cooling efficiency.

[0023] In summary, this application has at least the following beneficial effects: This application solves the problem that submersible pumps in the prior art are easily damaged when pumping media other than water, and have insufficient versatility. This application can be installed on the pump body, and a jacket into which coolant can be injected can be directly added to the outside of the pump body. The coolant in the jacket is used for cooling, so that the pump body can be used normally in a variety of environments, effectively improving versatility. Attached Figure Description

Both ends of the outer shell 1 are used to connect to the pump body. The inner shell 2, near the pump impeller, is also used to connect to the pump body. A coolant flow channel 3 is provided between the inner shell 2 and the outer shell 1. A coolant flow channel 3 is also provided between the inner shell 2 and the pump body after the inner shell 2 is connected. The coolant flow channels 3 are interconnected, allowing coolant to circulate. In specific implementations, a liquid with a high specific heat capacity, such as water, can be used as the coolant to effectively cool the pump body.

[0029] like Figure 1 and Figure 2 As shown, outer connecting plates 11 are provided at both ends along the length of the outer shell 1. One side of the outer connecting plate 11 is detachably connected to the outer shell 1, and the other side of the outer connecting plate 11 is detachably connected to the pump body. In specific implementation, the detachable connection between the outer connecting plate 11 and the pump body is achieved by bolts, and the connection with the outer shell 1 is also achieved by the same bolt connection method.

[0030] like Figure 1 and Figure 2 As shown, an inner connecting plate 21 is provided on the side of the inner shell 2 near the pump impeller. One side of the inner connecting plate 21 is detachably connected to the inner shell 2, and the other side of the inner connecting plate 21 is used for detachable connection to the pump body.

One side of the inner layer support member 211 is detachably connected to the inner layer connecting plate 21, and the other side of the inner layer support member 211 is detachably connected to the pump body. Multiple water inlets 112 are provided on the inner layer support member 211. In specific implementation, the inner layer support member 211 is used to support the inner layer shell 2, reducing the possibility of damage under pressure.
