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.
