The design of ultra long vertical multi-stage semi submersible long shaft deep well turbine pumps with an underwater depth of up to 100 meters or even longer requires breaking through the structural limits of conventional pumps, focusing on solving core challenges such as long shaft stability, sealing reliability, material corrosion and fatigue resistance, and maintenance feasibility under deep liquid conditions. At present, ultra long vertical multi-stage semi submersible long shaft deep well turbine pumps are mainly used in extreme engineering scenarios such as deep well water intake, seabed mining, and deep-sea drilling platform ballast systems....

The selection of H-series right-angle gearboxes must be tailored to the special needs of offshore engineering, with precise matching in four dimensions: parameter capacity, corrosion resistance and compatibility, spatial layout, and operation and maintenance support, to avoid significant losses caused by unplanned offshore production downtime due to improper selection....

The H series right angle gearbox is a transmission device designed specifically for pump equipment, which can convert the horizontal shaft power of horizontal prime movers (such as diesel engines and electric motors) into vertical shaft output. It is widely used in vertical pump systems such as deep well pumps, axial flow pumps, and diagonal flow pumps....
