ZJ50/3150D DC Electric Driving Drilling Rig
Full DC electric driving drilling rig, winch, rotary table, mud can achieve independent steeples speed to guarantee the optimization drilling technology.
Winch, draw works and floor equipments installed on introversion, adopts power of winch to rise.
Choosing to adopt AC frequency all-digital automatic control system of bit feed. Bit feed adopts all-digital automatic control technology, driller Operate it by touch screen with the most optimized drilling parameter, it can be reduce the working intensity of driller’s and improve work efficiency. Further, it can realize main drilling parameter‘sdisplay, storage, control and remote management.
