Description

Bearing support pipeline pump

Technical Field

The utility model relates to a tubing pump field, concretely relates to bearing support tubing pump.

Background

The pipeline pump is a single-suction single-stage or multi-stage centrifugal pump, belongs to a vertical structure, and is named as a pipeline pump because the inlet and the outlet of the pipeline pump are on the same straight line, have the same caliber, are similar to a section of pipeline and can be arranged at any position of the pipeline. The axial force of the traditional pipeline pump is generally directly borne by a bearing of a motor, the defect of inconvenient maintenance exists when the bearing is abraded due to long-time use, and the service life of the pump can be shortened.

Disclosure of Invention

For overcoming the problem that pipeline pump motor bearing leads to after damaging because of the axial force is difficult to overhaul among the prior art, the utility model aims to provide a bearing supports tubing pump.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

a bearing support pipeline pump comprises a motor, a pump shaft, an impeller and a pump shell, wherein the impeller is installed in the pump shell, the pump shaft is connected with the impeller and the motor, a bearing support is installed at the top of the pump shell, a pump cover is installed between the pump shell and the bearing support, a bearing block is installed at the top of the bearing support, a bearing is installed in the bearing block, and a bearing end cover is installed at the top of the bearing block; the motor support is supported on the top surface of the bearing seat, the motor is mounted on the motor support, the motor is connected with the top end of the pump shaft through the coupler, and the pump shaft sequentially penetrates through the bearing end cover, the bearing and the pump cover to be connected with the impeller.

Furthermore, a mechanical seal is arranged between the pump shaft and the pump cover.

Furthermore, the motor support and the bearing support are integrated into a whole, the upper end face and the lower end face of the support are flange faces and are respectively connected with the motor and the pump shell, and the bearing seat is arranged in the middle of the support.

Furthermore, a locking nut is installed at the lower end of the pump shaft, and two ends of the impeller are limited by the locking nut and a shaft shoulder of the pump shaft.

And furthermore, the bottom surface of the support and the top surface of the pump shell are respectively provided with an annular limiting groove matched with the corresponding end surface of the pump cover.

After taking above technical scheme, the beneficial effects of the utility model are that: the bracket is arranged between the motor and the pump shell, the bearing seat is arranged in the bracket and bears the axial force, so that the service life of the pump is prolonged, and the inspection and the maintenance are convenient.

Drawings

Fig. 1 is a schematic diagram of the mechanism of the present invention.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in the figure, a bearing support pipeline pump comprises a motor 1, a support 2, a pump shaft 3, a bearing seat 4, a pump cover 5, an impeller 6 and a pump shell 7. The upper end face and the lower end face of the support 2 are flange faces, the lower end face of the support 2 is fixedly connected with the pump shell 7, the motor 1 is installed on the upper end face of the support 2, the impeller 6 is installed in the pump shell 7, and the pump shaft 3 is connected with the impeller 6 and the motor 1. And a locking nut 8 is arranged at the bottom end of the pump shaft 3, and the impeller 6 is locked at the shaft shoulder at the bottom end of the pump shaft 3 by the locking nut 8. The pump cover 5 is arranged between the support 2 and the pump shell 7, and the bottom surface of the support 2 and the top surface of the pump shell 7 are respectively provided with an annular limiting groove matched with the corresponding end surface of the pump cover 5 to fix the pump cover 5. Bearing frame 4 fixed mounting is in the middle part in support 2, installs bearing 9 in the bearing frame 4, and the terminal surface is spacing by the counter bore in the bearing frame 4 under the bearing 9, and the up end of bearing 9 is spacing by the end cover 10 of installing in the top surface of bearing frame 4. The pump shaft 3 sequentially penetrates through the end cover 10, the bearing 9 and the pump cover 5 to be connected with the impeller 6. The upper end of the pump shaft 3 is connected with a shaft of the motor 1 through a coupling 11, and a mechanical seal 12 is arranged between the pump shaft 3 and the pump cover 5 to prevent the leakage of materials in the pump shell 7.
