Descrição do vídeo:
In this technical walkthrough, we demonstrate the K3V180DTP-9N PTO hydraulic main piston pump installed and operating in excavator applications. You'll see how this axial variable piston pump converts mechanical energy into hydraulic power, learn about its three control modes (constant power, load sensing, and pressure limit), and understand common failure symptoms like slow movement and engine overload. We'll also show maintenance best practices to protect your hydraulic system and maximize pump lifespan.
