Description

Technical Field

[0001] The utility model relates to the technical field of electric pump protection equipment, in particular to a mine flameproof submersible sand removal electric pump rotor shaft anti-jump device. Background Art

[0002] Mining flameproof submersible sand removal electric pumps are mainly used for drainage and sand removal operations in various types of mines such as coal mines, metal mines, and non-metallic mines. The working environment is harsh and requires extremely high reliability and stability of the equipment. The rotor shaft is one of the core components of the electric pump. Its vibration problem will directly affect the operating efficiency and stability of the electric pump, and may even cause equipment damage or safety accidents.

[0003] Traditional submersible sand-draining electric pumps often do not consider the anti-jump problem of the rotor. During high-speed rotation, the rotor may jump due to imbalance and other reasons. This jumping not only affects the performance and stability of the pump, but may also cause equipment damage. In order to solve the above problems, the utility model provides a mining explosion-proof submersible sand-draining electric pump rotor shaft anti-jump device. Utility Model Content

[0007] As a further improvement of the present invention, the anti-jump mechanism includes four sleeve rods fixedly connected to the inner wall of the mounting shell, and the opposite ends of the four sleeve rods are provided with movable grooves, and the insides of the four movable grooves are fixedly connected with damping buffers, and the other ends of the four damping buffers are fixedly connected to movable rods, and the opposite ends of the four movable rods are fixedly connected to the same anti-jump bearing, and the rotor body is rotatably connected to the anti-jump bearing.

[0008] As a further improvement of the present invention, a first threaded hole is provided at the lower end of the pump body and the upper end of the mounting shell, and a first fixing bolt adapted to the first threaded hole is threadedly connected to the lower end of the pump body.

[0009] As a further improvement of the present invention, a second threaded hole is provided at the lower end of the mounting shell and the upper end of the filter frame, and a second fixing bolt adapted to the second threaded hole is threadedly connected to the lower end of the mounting shell.

[0010] As a further improvement of the present invention, an impeller is fixedly mounted on the surface of the rotor body, and the impeller is rotatably connected to the pump body.

[0011] As a further improvement of the present invention, a top seat is fixedly installed on the upper surface of the pump body, a water outlet is fixedly connected to the middle end of the upper surface of the top seat, and a connecting cable is fixedly connected to one side of the upper surface of the top seat.

[0012] Beneficial effects of the utility model:

[0013] By setting up an anti-jump mechanism, when in use, the mounting shell and the anti-jump bearing inside it are connected to the rotor body of the pump body. The stable support of the anti-jump bearing reduces the jumping of the rotor body, ensuring the stability of the rotor body and the impeller during rotation, thereby reducing the noise generated during operation of the device and improving the working efficiency of the device. At the same time, the combined design of the movable rod and the damping buffer can absorb and alleviate the impact by moving the movable rod in the movable groove of the sleeve rod when encountering a strong impact, further reducing the vibration of the device and extending the service life of the device.

[0014] By setting up the mounting shell and the filter frame, when in use, a fixing method of a first threaded hole, a first fixing bolt, a second threaded hole, and a second fixing bolt is adopted, so that the connection between the mounting shell and the pump body, and the filter frame and the mounting shell is both firm and easy to disassemble, which not only simplifies the installation process, but also facilitates subsequent maintenance work, such as replacing the filter frame or checking the internal components of the pump. At the same time, the setting of the filter frame effectively filters impurities in the water flow, avoids the wear of impurities on the internal components of the device, and ensures the long-term and efficient operation of the device.

[0015] In summary, the utility model effectively improves the stability, working efficiency, safety and reliability of the pump, simplifies the installation and maintenance process, improves the user experience, and increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
