[0019] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 As shown, the submersible pump guide bearing housing of this utility model embodiment includes: a housing body 1, a guide cone 2, and a guide rib 3.

[0021] The base 1 has a flow channel 11 in the middle, and both ends of the flow channel 11 pass through the base 1. During the assembly of the submersible pump, the base 1 is used as part of the pump body.

[0022] The guide cone 2 is located inside the flow channel 11. The middle part of the guide cone 2 has a liquid collection groove 21, a liquid collecting groove 22, and a flow passage groove 23. The liquid collecting groove 22 is connected to the liquid collection groove 21 through the flow passage groove 23. The guide cone 2 is used to install the thrust bearing. The guide cone 2 has a through hole structure inside for the pump shaft to pass through and for the thrust bearing to be installed.

[0023] The guide rib 3 is connected to the inner wall of the base 1 and the outer wall of the guide cone 2 on both sides. The guide rib 3 has a pressure relief hole 31, a pressure measuring hole 32, and a temperature measuring hole 33. One end of the pressure relief hole 31 is connected to the liquid collection tank 22, and the other end of the pressure relief hole 31 penetrates the outer wall of the base 1. One end of the pressure measuring hole 32 and one end of the temperature measuring hole 33 are both connected to the liquid collection tank 21, and the other ends of the pressure measuring hole 32 and the temperature measuring hole 33 both penetrate the outer wall of the base 1. The guide rib 3 adopts a streamlined shape, which allows the fluid to flow smoothly through the flow channel 11.

[0024] Based on the above structural configuration, the fluid flows from the flow channel 11 outside the guide cone 2. With the help of the guide rib 3, the resistance can be reduced. The liquid collection tank 22 is connected to the liquid receiving tank 21 through the flow channel 23, and one end of the pressure relief hole 31 is connected to the liquid collection tank 22, thereby forming a liquid cooling channel inside the guide cone 2.

[0025] like Figure 1 As shown, in some embodiments, the flow guide cone 2 has a first O-ring 24 in the middle, and the first O-ring 24 is located at one end of the liquid collection tank 21. In this way, an O-ring can be installed through the first O-ring 24, and when one end of the flow guide cone 21 is installed with the flow guide cover, the sealing ring can ensure a seal between the two.

[0026] like Figure 1 As shown, in some embodiments, the guide cone 2 has a second O-ring 25 in the middle, and the second O-ring 25 is located at the other end of the liquid receiving tank 2. In this way, an O-ring can be installed through the second O-ring 25, and when a thrust bearing is installed inside the guide cone 2, the sealing ring can ensure a seal between the two.

[0027] like Figure 1 As shown, in some embodiments, the end face of the liquid receiving groove 21 near the second O-ring 25 is a bearing surface 26, which is used to abut against the outer wall of the thrust bearing. This ensures the stability of the thrust bearing mounting structure.

[0028] like Figure 1 As shown, in some embodiments, the liquid collection tank 22 is arranged in a ring shape, and the liquid collection tank 22 is spaced outside the second O-ring 25. This helps to increase the area of ​​the liquid collection tank 22 within the guide cone 2, thereby improving the heat dissipation effect of the liquid.

[0029] like Figure 1 As shown, in some embodiments, one end of the base 1 has a first vibration measuring hole 12, which is arranged vertically. Thus, a vibration probe is installed in the first vibration measuring hole 12 to detect the vibration data of the base 1.

[0030] like Figure 1 As shown, in some embodiments, the other end of the base 1 has a second vibration measuring hole 13, which is arranged laterally. Thus, a vibration probe is installed in the second vibration measuring hole 13 to detect the vibration data of the base 1.

[0031] Data detection is performed by installing vibration probes in the first vibration measuring hole 12 and the second vibration measuring hole 13 at different locations, which helps to improve the accuracy of the detection.

[0032] like Figure 1 As shown, in some embodiments, the middle part of the flow channel 11 is arranged in an outward arc shape, and the guide cone 2 is disposed in the middle part of the flow channel 11. In this way, the middle part of the flow channel 11 has sufficient space to ensure normal fluid flow.

[0033] In some embodiments, the guide rib 3 is integrally formed with the base 1. Specifically, it is formed by casting.

[0034] In some embodiments, the axis of the pressure measuring hole 32 and the axis of the temperature measuring hole 33 coincide. Thus, a pressure probe is installed in the pressure measuring hole 32 to measure hydraulic pressure, and a temperature probe is installed in the temperature measuring hole 33 to measure temperature.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
