Description

Technical Field

[0001] This application belongs to the field of vertical pumps, and particularly relates to a split-type motor bracket for a vertical pump. Background Technology

[0002] Vertical pumps are key equipment in chemical, petroleum, and power industries for transporting cryogenic, high-pressure, and easily vaporized liquids. The reliability of their motor brackets directly affects system operating efficiency. In existing technologies, the motor and pump body are typically directly connected via an integrated motor bracket. While this simplifies the initial installation process, it has significant drawbacks: the integrated design necessitates disassembling the entire bracket and pump body components when repairing the motor or replacing the coupling, greatly increasing maintenance complexity and downtime; simultaneously, the rigid connection between the motor and pump easily transmits vibration to the pump body, accelerating component wear and reducing operational stability; furthermore, the integrated bracket requires stringent manufacturing and installation precision, and even minor deviations can lead to misalignment, causing operational imbalance and additional mechanical losses, while the high-precision machining requirements further drive up manufacturing costs. More importantly, traditional solutions require dedicated brackets for motors of different power ratings, forcing companies to stock multiple specifications, increasing production costs and creating inventory management pressures; the inherent deformability and inconsistent precision of the integral welded structure also limit its versatility. Therefore, it is necessary to solve these technical problems. Utility Model Content

The upper connecting plate and the bridging plate are stacked and detachably connected. The lower connecting plate is parallel to the upper connecting plate and is used to connect the target vertical pump. The lower connecting plate, the upper connecting plate, the bridging plate and the motor mounting plate are respectively provided with through holes so that the motor shaft of the target motor can be connected to the pump shaft of the target vertical pump.

[0007] Optionally, a step is formed on the side of the upper connecting plate opposite to the lower connecting plate;

[0008] The bridging plate forms a protrusion adapted to the step to limit its own sliding relative to the upper connecting plate along the radial direction of the first cylinder.

[0011] Optionally, the first support further includes an inner ring connected to the inner wall of the first cylinder;

[0012] The inner ring is coaxial with the first cylinder and is arranged parallel to and spaced apart from the motor mounting plate and the bridge plate, respectively.

[0013] Optionally, the first support further includes a first inner rib plate disposed inside the first cylinder;

[0014] The first inner rib is parallel to the axial direction of the first cylinder and is connected to the motor mounting plate, the inner ring, and the inner wall of the first cylinder, respectively.

[0024] The advantages of the split-type motor bracket for vertical pumps provided in this application are as follows: Compared with the prior art, in the split-type motor bracket for vertical pumps provided in this application, the first bracket is detachably connected to the upper connecting plate of the second bracket connected to the second cylinder via a bridge plate connected to the first cylinder. Since the lower connecting plate, upper connecting plate, bridge plate, and motor mounting plate are respectively provided with through holes, when the target motor is mounted on the motor mounting plate and the target vertical pump is mounted on the lower connecting plate, the motor shaft of the target motor can pass through the first cylinder and the pump shaft of the target vertical pump can pass through the second cylinder. In later use, the detachably connected first and second brackets not only facilitate individual maintenance of the target motor and the target vertical pump, but the second bracket can also adapt the same target vertical pump to different types of target motors by adapting to first brackets of different sizes. Furthermore, the split design reduces direct mechanical transmission between the target motor and the target pump body, thereby reducing system vibration and noise. This makes the split-type motor bracket for vertical pumps provided in this application a flexible and convenient user experience, far superior to the prior art. Attached Figure Description

[0034] Please refer to the following: Figures 1 to 3 The present application will now describe a vertical pump split-type motor bracket according to an embodiment. This vertical pump split-type motor bracket includes a first bracket 101 and a second bracket 102. Wherein:

[0035] The first support 101 includes a first cylinder 111 and a motor mounting plate 112 and a bridging plate 113 axially connected to both ends of the first cylinder 111.
