Key Features
High Efficiency & Energy Saving: Eliminates intermediate transmission components such as belts, boosting system efficiency to 92%. Achieves an overall power savings of 20%–30%, with a power factor approaching 1.
Safety & Environmental Protection: Completely eliminates safety hazards associated with belt breakage and injury, as well as issues like uneven wear and oil leakage. Generates no noise, odors, or solid waste, thereby improving the operational environment.
Low Maintenance Costs: Saves approximately 3,000 RMB per unit annually in belt-related maintenance expenses. Extends the service life of the gearbox and reduces labor intensity.
Precise & Adjustable Stroke Rate: The control panel directly displays the stroke rate, offering stepless speed regulation down to a minimum of 0.3 strokes per minute. Ensures smooth operation and is well-suited for complex operating conditions, such as those found in low-yield wells and heavy oil wells.
Intelligent Protection: Features comprehensive protection mechanisms against overcurrent, overvoltage, overheating, and phase loss. Enables soft start and stop functions to prevent mechanical shock. Supports remote monitoring and integration with oilfield IoT systems.
Convenient Retrofitting: Allows for the direct, in-situ replacement of the original belt pulley. Requires no structural modifications to the existing pumping unit and remains fully compatible with established operational modes.
