Technical Field

[0001] This invention relates to the field of rotary lobe technology, and more specifically to the field of rotary lobe technology for water pumps. Background Technology

[0002] Multistage centrifugal pumps are crucial equipment in underground mining operations, playing a vital role in ensuring safe and efficient production. However, in actual mining operations, factors such as mud and water in the mining area can significantly impact water quality. If the pumps fail to start and drain water in a timely manner, it can obstruct the drainage system and even threaten the lives of workers. Therefore, before starting underground drainage pumps, manual operation is required. Traditionally, this is done manually, but manual operation is inefficient, labor-intensive, and unsuitable for the demands of modern intelligent mine drainage systems. Using a manual pump control device offers higher reliability and stability, but existing devices are not easily adjustable, lack practicality, and are not convenient to operate.
