F Series
Technical Description
▶ Gear pair. Integral herringbone gear transmission, high transmission torque, stable operation.▶ Frame. It is welded from steel plates and annealed after welding. Necessary oil pools and passages are provided in the frame.
▶ Crankshaft. It is an alloy steel casting, and both ends of the crankshaft are equipped with double row centripetal spherical roller bearings.
▶ Gear shaft. It is an alloy steel forging with herringbone teeth machined on the shaft. Both ends of the shaft can be extended to install a transmission device.
▶ Cross head. It is integrally cast with ductile iron and has good wear resistance.
▶ Valve assembly. Configure API-7K standard valve.

▶ Fluid cylinder. Made of alloy steel forgings, available in two structural types: I-type and L-type. The I-type fluid end has a compact structure, while the L-type is easier to maintain.
▶ Lubrication system. A combination of forced lubrication and splash lubrication is adopted. An externally mounted motor-driven oil pump can also be used according to user requirements.
▶ Spray system. A centrifugal pump supplies cooling liquid to the cylinder liner. It is driven by a belt pulley mounted on the main pump transmission shaft, and can also be driven independently by an electric motor.
▶ Jib crane system. Installed on the frame for disassembly and replacement of fluid end components such as cylinder liners. It helps reduce the labor intensity of drilling workers.
▶ Safety valve. Two options are available: shear pin type safety valve and spring-reset safety valve.
