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.
It can transport high concentration and high viscosity<10000PaS and suspended slurry containing particles.
The conveying liquid flow is stable, no over-current, pulsation and stirring, shearing slurry phenomenon.
The discharge pressure is independent of the speed, and the low flow rate can also maintain a high discharge pressure.
The flow rate is proportional to the speed. The flow adjustment can be realized by the shifting mechanism or the speed regulating motor.
Self-priming ability, without the bottom valve can directly pump liquid.
The pump can be reversed, and the liquid flow direction is changed by the rotation direction of the pump, which is suitable for the occasion where the pipeline needs to be reversely flushed.
Smooth operation, vibration and low noise.
Simple structure, convenient disassembly and assembly.
3NB500 Series Mud Pumps are mainly used for oil, water well, geothermy, CBM, shale gas, coalfield exploration, freezing well as well as well other drilling ,well cementation, work-over and other operations in industrial and mining enterprises. It is used for transferring mud, clay gum, mortar and other medium to the borehole. The pump adopts international advanced technology. It is characterized by advanced structure, reliable operation, good suction performance, long service life of wearing parts, easy for maintenance and repairing and so on.
