Product Description

Product Description

3NB series design Features 1

The 3NB series drilling pump is a horizontal piston pump used for drilling. During the design process, the guiding ideology of "appropriately increasing stroke length, reasonably reducing rated pump speed, improving suction performance, and increasing component life" was reflected. It has the characteristics of high power, light weight, sufficient strength, and good sealing.

3NB series design Features 2

Adopting an upright integral forging valve box and a forged welded integral exhaust manifold, and using integral forging to exhaust the pre compressed air bag. Small clearance volume, minimal pressure fluctuations, high suction efficiency, and good sealing performance.   The crankshaft structure with forged straight shaft and eccentric wheel is used for shaping, replacing the hollow crankshaft structure cast as a whole. Good economic benefits, easy to manufacture, easy to use, and easy to repair.

3NB series design Features 3

The 3NB series of drilling pumps consists of two main parts: the power end and the hydraulic end. The power end includes the pump seat, pump casing, drive shaft, crankshaft, gear pair, and connecting rod cross head components; The hydraulic end includes components such as a high-pressure valve box, a discharge manifold assembly, and a suction manifold assembly. The herringbone gears, bearings, and crosshead guide plates on the power end are lubricated with splash gravity lubrication. The cylinder liner and piston at the hydraulic end are sprayed and cooled by a dedicated centrifugal pump

Using a diesel engine to drive an independent mechanical pump unit, which can be connected by a belt or hydrualic coupler. Diesel engines can be selected from Weichai, Jichai, and other original engines..

Driven by an electric motor, it can be made into an electric motor pump unit, which can be connected by a belt or a coupler. The motor can be selected from international first-line brands or well-known Chinese brands
