High gear precision,good meshing,low temperature rise,and better durability.
High Gear Precision & Good Meshing: The gears and gear shafts are made of 18CrNiMo7-6 material and manufactured through processes including gear hobbing, carburizing and quenching, and gear grinding. This ensures high gear precision and good meshing for smooth power transmission in fracturing operations.
Low Temperature Rise & Better Durability: Engineered for oil and natural gas exploitation, this gearbox features low temperature rise and better durability. The fully assembled gearbox undergoes commissioning tests, including lubricating oil temperature rise measurement, to guarantee stable performance under working conditions.
Robust Structural Integrity: The gearbox housing is fabricated by welding Q235 steel plates, providing a robust and rigid structure to withstand high torque in oil and natural gas exploitation.
Product Overview: The Model 2500 gearbox is one of our flagship products. It is mainly used as a fracturing pump gearbox for oil and natural gas exploitation, and the product is mainly marketed in China and the United States.
Core Technical Parameters: Features a rated power of 1865 kW and a speed ratio of 6.375:1. It is assembled with a housing, a cover, gears, gear shafts, bearings, and other components.
Comprehensive Manufacturing & Assembly Process: Our manufacturing process includes gear hobbing, carburizing and quenching, and gear grinding for 18CrNiMo7-6 components, followed by assembly with the Q235 welded housing to form the complete gearbox.
Traceability & Commissioning Tests: To ensure product quality and facilitate traceability, each component is engraved with a unique serial number and matched with a process card. Before delivery, the gearbox undergoes commissioning tests, including noise testing and abnormal sound detection. Only after all parameters meet design requirements will it be painted, cleaned, and packaged.
Custom Gearbox Design & Development: To meet different customer needs, our company can carry out design and development or customized production according to customers' requirements or provided drawings.
