Description

Technical Field

[0001] This utility model relates to the field of vertical axial flow pump technology, and in particular to a multi-foundation long-shaft vertical axial flow pump. Background Technology

[0002] The main difference between vertical axial flow pumps and submersible axial flow pumps is that the motor of a vertical axial flow pump is located above the water surface, separate from the pump body, and connected via a pump shaft, making it a dry-installation type. Due to the structural characteristics of vertical axial flow pumps, they are inconvenient to fix, and their relatively long pump shaft results in lower stability during high-speed rotation, making them prone to shaking and damage. Existing technologies also include some vertical axial flow pump installation methods using dual or multiple foundations.

[0003] For example, the Chinese invention patent with application number CN202111610710.2, entitled "Stable Double-Foundation Vertical Axial Flow Pump," uses a first and second fixing plate fixed to the outer wall of the axial flow pump. Then, with the help of a connecting rod, a stabilizing seat, and fixing screws, the pump is stably supported, ensuring greater stability during operation. However, it primarily supports the main body of the vertical axial flow pump, and its effect on stabilizing the long rotating shaft of the pump is limited.

[0004] For example, Chinese utility model patent application number CN201921704808.2, entitled "A Double-Foundation Vertical Axial Flow Pump," uses annular fixing plates on the upper and lower parts of the upper floor slab to ensure the stability of the upper motor support, and rectangular fixing plates on the upper and lower parts of the lower floor slab to ensure the stability of the axial flow pump, making it suitable for various installation environments. However, its effect on stabilizing the long shaft of the vertical axial flow pump is also limited. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-foundation long-shaft vertical axial flow pump, which is easy to install and fix, can ensure the stability of the axial flow pump during operation, and reduce the shaking of the axial flow pump.

[0006] This utility model is achieved using the following technical solution: a multi-foundation long-shaft vertical axial flow pump, comprising a motor, a pump shaft, a pump shaft support, a pump body, a motor base, and a pump body support plate. The motor is fixed to the top of the motor base with bolts, and the motor base is used to support and fix the motor. The pump body has a pump body support plate fixed in the vertical direction for supporting the pump body. The pump shaft support is located between the motor base and the pump body. The upper end of the pump shaft is connected and fixed to the drive end of the motor, and the bottom end of the pump shaft is connected and fixed to the impeller in the pump body. The middle part of the pump shaft is rotatably installed in the pump shaft support.

[0007] Furthermore, the pump shaft support includes a pump shaft support plate, a central bearing seat, and a rib plate. The central bearing seat is fixed to the upper center of the pump shaft support plate, and the rib plate is connected and fixed between the outer side of the central bearing seat and the upper end of the pump shaft support plate.

[0008] Furthermore, the main body of the water pump includes an inlet, a pump body, a bend, a support bearing seat, and an outlet pipe. The inlet is connected to the bottom end of the pump body via a flange. The upper end of the pump body is connected to the bottom end of the bend via a flange. The rear end of the outlet pipe is connected to the front end of the bend via a flange. The outlet pipe is horizontally positioned. The support bearing seat is vertically connected to the upper rear end of the bend. The pump body support plate is fixed to the bottom of the bend.

[0009] Furthermore, the rear part of the water outlet pipe is fixed in the water outlet pipe support.

[0010] Furthermore, the pump shaft support, motor base, and pump body support plate are all equipped with shock-absorbing pads at their bottom ends.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a multi-foundation long-shaft vertical axial flow pump, which uses a motor base to support and fix the motor, a pump body support plate and a water outlet pipe support to support the pump body, and a pump shaft support seat to support the middle part of the pump shaft. Through the installation method of multiple foundation supports, the long-shaft vertical axial flow pump is installed stably and is easy to install and fix. It can effectively improve the stability of the long-shaft vertical axial flow pump during operation, reduce pump shaft shaking, and improve its working stability. Attached Figure Description
