Water-conducting Preloading Mechanism for Hydropower
The water-conducting preloading mechanism is an indispensable supporting component of hydro-turbine wicket-gate mechanism. It is installed together with guide vane levers, bushings, connecting links and control ring assemblies. Its core function is to exert balanced pre-compression force on each transmission joint of the guide-vane operating system, offset assembly gaps, and restrain joint looseness induced by water hammer impact, unit vibration and cyclic alternating loads during continuous operation.
Without reliable pre-loading, the guide-vane transmission system will suffer loose joints, position offset, guide-vane clamping failure, abnormal mechanical knocking, aggravated seal wear, increased leakage, and even broken shear pins, which will bring huge hidden dangers to unit safety and raise maintenance costs and unplanned downtime losses.
Custom Manufacturing Service
We provide full-set custom manufacturing service for water-conducting preloading mechanisms. We develop solutions strictly based on customer-provided drawings, turbine model, unit capacity, water quality condition and installation space requirements.
Main Structural & Technical Features
High-strength material selection: Main body adopts high-performance cast alloy steel. Optional overlay welding and surface anti-corrosion coating for silt-laden and corrosive water-quality working conditions.
Precision machining: CNC finish-machined mating surfaces to ensure even pre-load transfer for every guide-vane transmission point, avoiding uneven stress distribution among multiple sets of guide vanes.
Stable pre-load performance: Optimized pre-load structure design, resisting long-time vibration and water-hammer impact, keeping pre-tightening status stable during unit load adjustment, start-stop cyclic operation.
Easy installation & maintenance: Modular structure, convenient for field assembly, adjustment and later overhaul replacement.
