Description de la vidéo:
Follow the narrative to see how small design choices affect everyday performance. In this video, we demonstrate the Nachi PVD-00B-18B-5 hydraulic piston pump installed in Kubota U15-3 and Hitachi ZX17/ZX18 mini excavators. You'll learn how axial piston pumps convert mechanical energy into hydraulic power, witness the critical role of swash plate angle adjustments in controlling displacement, and understand how LS load-sensing and constant power control systems optimize performance while preventing engine overload. We'll also walk through common failure scenarios like internal leakage and regulator issues, plus share essential maintenance practices to ensure long-term reliability.
