Problem: The equipment bucket runner was broken, it had many penetration cracks. The unit consumed a large amount of water and the output was low. The leaking oil from the nozzle leads to mix oil and water. The mechanical feedback device jams and the unit frequently fails
New runner model: CJGT003-L-130/4×10，Nozzle: Straight flow oil control nozzle
Solution: The runner was built with ultra-low carbon refining steel casting technology and entire CNC machining. the output increased and efficiency improved. The first refurbished turbine runner have already been running for 5 years with no cracks. The oil and water mixing problem was solved by using the German double-output magnetostrictive displacement sensor to feedback the accurate stroke.
