Drilling Pump

3NBZ series drilling pumps, which are used to circulate drilling fluids, cleaning bottom of the hole, carry the drill cuttings out of the hole, cool, clean and lubricate the bit, and support the wall in drilling operation in oil and gas field, are a kind of horizontal medium-speed triplex single-acting piston pump. It is especially suited to high press-ure jet drilling for increasing penetration rate, and it can also supply flowing drilling fluids for downhole motors to drive the downhole drilling machinery and downhole tools. 3NBZ series drilling pumps take the advantages of the current L-shaped pumps take the advantages of the current L-shaped pumps and vertical pumps in the world. This new series of triplex pump which possesses lighter weight, smoother discharge flow, lower pressure fluctuation, reliable operation, easier maintenance, longer service life and higher efficiensy, are originated by our factory.

3NBZ series drilling pumps are composed of the power end and the fluid end. The power end includes the following parts such as: frame, a drive shaft, a driven shaft, a transmission shaft of lubricating oil pump, and a lubricating system. The fluid end includes the following parts such as: valve pots, liners and pistons, high pressure manifolds, suction manifolds.

To prevent air pockets and to reduce pressure fluctuation, an upright pulsation dampener are reparately mounted on the suction manifolds and by the exhaust inlet of high pressure manifolds in fluid end.

The gears, shafts, crossheads, and guide blocks in the power end are lubricated by a dual-protection lubrication system with a gravity-splash lubricaion and pressure-fed lubrication.
