[0002] As a key facility in water conservancy projects, pump stations undertake multiple tasks such as drainage, irrigation, and water supply, and play a crucial role in ensuring regional water resource management, flood control and drainage, and agricultural irrigation. Pump stations are usually equipped with powerful water pump systems that are driven by motors to pump accumulated water or water sources from low-lying areas to higher areas or designated areas to meet various water conservancy needs.
