ZJ40/2250LDB , control , remote man , Oil Drilling Rig good quality and high efficiency
Description:
Driving of RT and DW is independent, RT rev, torque and mud pump
stroke can be adjusted separately as per drilling technology, which
provides precondition and guarantee for drilling technology
optimization and auto-bit-feeding realization.
RT and auto-bit-feeding both adopt AC VF all-digital auto control
technique, which make the performance of the rig under drilling
condition get close to digital-control electric VF rig; but its
cost is much lower. Driller operates the touch screen to fulfill
drilling operation through optimized drilling parameters, which
will reduce labor intensity significantly and improve work
efficiency. Display, restoration, regulation and control, remote
management of major drilling parameters can be realized.
