Technical Description
▶ Gear pair Integral herringbone gear transmission provides high torque capacity and smooth operation.▶ Frame Fabricated from welded steel plates and annealed after welding. Necessary oil reservoirs and oil passages are arranged inside the frame.
▶ Crankshaft Made of built-up alloy steel forgings and fully balanced. Double-row tapered roller bearings are used at both ends of the crankshaft.
▶ Pinion shaft Made of alloy steel forgings, with herringbone teeth machined on the shaft. Both shaft extensions can be fitted with transmission devices.
▶ Crosshead Integrally cast from nodular iron, providing good wear resistance.
▶ Lubrication system Splash lubrication is adopted.
▶ Fluid cylinder Made of alloy steel forgings, with an L-type structure for easy maintenance.

▶ Spray system A centrifugal pump supplies cooling liquid to the cylinder liners. It can be belt-driven by a pulley mounted on the main pump transmission shaft, or driven independently by an electric motor.
▶ Jib crane system Installed on the frame for use when dismantling and replacing 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.If you have any special requirements for mud pumps, please contact Rongsheng’s technical staff.
