Energy-saving pumping unit for reclamation wells

Abstract

This utility model relates to agriculture, specifically land reclamation and water supply systems, and is designed for lifting water from vertical wells and boreholes. The technical objective of this utility model is to improve the energy efficiency and operational reliability of the pumping unit. The essence of the utility model is an energy-efficient centrifugal pump unit installed on the ground surface, designed with a separate rotor and impeller. Water is lifted through a suction pipe equipped with a check valve, which maintains a constant liquid column and prevents unnecessary energy loss during repeated starts. Separating the structural components optimizes hydraulic parameters and significantly simplifies maintenance. This utility model ensures a stable water supply while significantly reducing specific energy consumption and operating costs, making it effective for a wide range of wells with varying dynamic water levels.
