High Efficiency Electrical Onshore Oil Drilling Rig ZJ50/3150LDB

 

Description:
 
On the basis of common mechanical rig, driving of RT a is separated from mud pump and DW, and RT is driven by an independent AC VF motor. RT rev, torque and mud pump stroke can be adjusted separately as per drilling technology.
RT rev adjusting and DW auto-bit-feeding both adopt all-digital auto control technique, which make the performance of the rig under drilling condition get close to digital-control electric VF rig; 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.
