In the commonly used positive circulation drilling, it is to send the surface flushing medium—clear water, mud or polymer rinsing liquid to the bottom end of the drill bit through a high-pressure hose, faucet and drill rod center hole under a certain pressure. Cool the drill bit, remove the cut debris and transport it to the surface.
The commonly used mud pump is a piston type or a plunger type, and the crankshaft of the pump is driven by the power machine, and the crankshaft passes the crosshead to drive the piston or the plunger to reciprocate in the pump cylinder. Under the alternating action of the suction and discharge valves, the purpose of pumping and circulating the flushing liquid is achieved.
The 3NB series mud pump is designed to have optimized parameters, providing increased stroke and capacity. We reduce the stroke rate reasonably to improve suction capability and extend service life of wearing parts.
The 3NB series mud pump is typically used in oil-field and industrial and mineral enterprises. It is also suitable for drilling, well workover and long distance transportation of liquid media.
