Features a built-in brake drum to prevent reverse rotation. Torque is released slowly and automatically. Operating torque and sucker rod requirements are significantly reduced, leading to lower investment costs.
Utilizes a gear pump and hydraulic valve group for automatic lubrication and braking. When reversing, it triggers a "lock-release-reverse" cycle to ensure a safe shutdown.
Adopts permanent magnet synchronous and frequency conversion technology. Designed for advanced performance and reliability.
