Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a single-stage pump structure with adjustable outlet direction. Background Technology

[0002] The new single-stage, single-suction horizontal centrifugal pump adopts an extended shaft motor structure design, eliminating the need for a separate pump rotor assembly. The mechanical seal, impeller, and impeller nut are directly assembled onto the motor shaft extension. The pump features a compact structure, small size, stable operation, low noise, and high component concentricity. The pump body has a horizontal foot-mounted structure, with horizontal axial suction and a 90-degree vertical upward outlet. It forms a complete pump unit structure with the impeller, pump cover, B35 extended shaft motor, and base. The pump cover passes through the extended shaft extension, and the pump cover flange is connected to the extended shaft motor flange. The impeller passes through the extended shaft extension and is fixed to the extended shaft end by applying preload force with the impeller nut. The pump body feet and the B35 extended shaft motor feet are together fixed to the base.

[0003] In practical use, pumps with this structure have the following drawbacks:

[0004] The direct-drive single-stage pump has a rear-opening structure. When repairing or replacing spare parts, the pump body can only be opened for repair and replacement by disassembling and moving the motor. If a large pump set is equipped with a high-power motor, disassembly and movement are quite difficult, increasing maintenance time and costs.

[0005] Because the support base of a direct-drive single-stage pump is cast onto the pump body, the pump outlet can only be installed vertically upwards when viewed from the pump inlet. If the installation direction of the pump outlet needs to be changed, or rotated counterclockwise or clockwise by a certain angle, the pump body mold needs to be modified, the mold needs to be re-opened, or the pump body base needs to be cut off, the outlet direction adjusted, and then re-welded. The above methods are time-consuming and labor-intensive, have high production costs, affect the flexibility of use, and the stability, reliability, and service life of the pump cannot be guaranteed. Summary of the Invention

[0006] To address the problems existing in the prior art, this utility model provides a single-stage pump structure with adjustable outlet direction, optimizing the pump's assembly and support structure, and improving the pump's operational stability and reliability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model proposes a single-stage pump structure with adjustable outlet direction, including a motor, pump cover, impeller, pump body, inlet section, and base. The motor, pump cover, pump body, and inlet section are arranged sequentially from front to back. The rear end of the motor has a motor flange, the front end of the pump cover has a first pump cover flange, and the first pump cover flange and the motor flange are fixedly connected by bolts. The rear part of the pump cover has a second pump cover flange. The front and rear ends of the pump body have a first pump body flange and a second pump body flange symmetrically arranged, and the first pump body flange and the second pump cover flange are fixedly connected by bolts. The rear end of the inlet section has an inlet section flange, and the inlet section flange and the second pump body flange are fixedly connected by bolts. The lower end of the front part of the pump cover has a pump cover foot, and the pump cover is fixedly supported on the base by the pump cover foot. The lower end of the inlet section has an inlet section foot, and the inlet section is fixedly supported on the base by the inlet section foot. The lower end of the motor has a motor foot, and the motor is fixedly supported on the base by the motor foot.

[0009] Furthermore, the pump cover is provided with two pump cover feet, which are symmetrically fixed to the base.

[0010] Furthermore, the water inlet section is provided with two water inlet section feet, which are symmetrically fixed to the base.

[0011] Compared with the prior art, the present invention has the following technical effects:

[0012] This utility model has a front and rear door opening structure. When inspecting or replacing spare parts, it can not only disassemble the pump body by removing the motor for inspection and replacement, but also disassemble the pump body by removing the water inlet section for inspection and replacement of impeller or mechanical seal. Disassembly is flexible and convenient.

[0013] The pump body of this utility model is supported by the motor base, the pump cover base, and the inlet section base. The pump body can be adjusted and assembled at multiple angles between the pump cover and the inlet section. From the pump inlet direction, the pump outlet direction can be adjusted at multiple angles, making it flexible to use, fully meeting the on-site pipeline assembly requirements, and reducing piping costs.
