Huadian Tianjin Junliangcheng Power Plant 300MW Circulating Water Pump Unit Vertical Long Axis Semi submersible Circulating Water Turbine Pumps

The vertical long shaft semi submersible circulating water turbine pump produced by Lijia Machinery, which is matched with the 300MW unit of Huadian Tianjin Junliangcheng Power Plant, is fully suitable for the core working conditions of high flow and low head circulating water in power plants, and is a key equipment to ensure the stability of condenser cooling water supply.
Strong structural adaptability: The motor is arranged above the liquid level, and the pump body adopts a multi section lifting pipe design, which can flexibly adjust the underwater length according to the actual depth of the suction well. Single foundation installation greatly reduces the difficulty of civil construction.
Full operational stability: The impeller is completely submerged below the lowest water level, eliminating the risk of cavitation from the root, meeting the 24-hour uninterrupted continuous operation requirements of the power plant, and complying with the strict restrictions on vibration and noise in the industry standard CJ/T 235-2017.
High operational convenience: Adopting a rotor withdrawable design, daily maintenance does not require the complete disassembly of the pump body and external pipelines. Core components such as impellers and guide vanes can be directly extracted from the upper part to complete maintenance, greatly reducing downtime for maintenance.
