[0002] In the coal mine production process, centrifugal pumps are very important as key drainage equipment. The main function of the centrifugal pump is to extract accumulated water from the mine to ensure the dryness and safety of the internal environment of the mine, thereby preventing the adverse effects of floods on coal mine production. However, since the working environment of coal mines is often harsh, accompanied by high humidity, high dust and high corrosion, it will affect the performance and life of the centrifugal pump to a certain extent.

Although they can meet basic drainage needs in terms of basic issues, they have obvious deficiencies in wear resistance and ease of movement. The lack of wear resistance causes centrifugal pumps to be easily damaged in coal mine environments, affecting production efficiency and safety; and the inconvenience of movement limits the rapid deployment and transfer of centrifugal pumps between different working surfaces, further affecting the production flexibility of coal mines. Therefore, developing a centrifugal pump that is both wear-resistant and easy to move is of great significance to improving the production efficiency and safety of coal mines. Utility Model Content

[0025] Working principle of the utility model: First, when using it, it is necessary to ensure that the pump body 1 and the base 2, mechanical port 3, coupling 4 and other components are correctly installed and tightened. The impeller 103 inside the pump body 1 is connected to the driving device (such as an electric motor) through the shaft seat 104 and the bearing 107. When the driving device is started, it will transmit the rotational power to the impeller 103 of the pump body 1 through the coupling 4. The elastic element 401 in the coupling 4 plays a key role in this process. It can not only absorb and buffer the additional load caused by shaft misalignment, vibration and impact, but also maintain a stable connection between the pump body 1 and the driving device. The locking screw 402 ensures that the various components of the coupling 4 are in the transmission of torque. The impeller 103 of the pump body 1 starts to rotate and generates centrifugal force after obtaining the rotational power, thereby pushing the sucked fluid to the discharge port 102. At the same time, the mechanical seal structure in the mechanical port 3 (including the mechanical seal cover 301, the static ring seat 302 and the dynamic ring seat 303) ensures that the pump body 1 will not leak during operation. The valve 6 is used to control the fluid flow inside the pump body 1. The valve 6 can be opened or closed as needed to adjust the flow or perform other operations. Components such as the balance pipe 9 and the protective body 8 also play a key role. The balance pipe 9 is used to balance the pressure inside the pump body 1 to ensure the stable operation of the pump; and the protective body 8 protects the pump body 1 from the influence of the external environment.
