We perform manufacturing, wear repairs, and sealing surface revisions of wicket gates that control water flow in hydroelectric power plants, in accordance with the original hydraulic form.
As Tekmaksan Engineering, we offer expert manufacturing and repair solutions for wicket gates, which are one of the most critical mechanisms directly affecting the efficiency of hydroelectric power plants (HEPP). These gates, which control the flow rate and direction of water in Francis and Kaplan type turbines, are exposed to mechanical wear over time caused by silt erosion, cavitation, and continuous opening-closing movements. Deterioration of vane profiles or gaps in closing surfaces cause serious water leakage and a decrease in turbine efficiency. Our company repairs damaged wicket gates with stainless steel overlay welding and special coating methods, machining them exactly to the original hydraulic profile form on our 5-axis CNC benches. If the gates are beyond repair, we manufacture high-strength new gates using forging or casting methods. Our scope of service includes not only the vane surface but also the correction of bends in the gate stems, revision of bushing bearing seats, and sealing tests. Wicket gates renewed with Tekmaksan Engineering prevent water leakage by ensuring full closure and allow your turbine to generate energy at maximum capacity.
