ZJ50 / 3150DB Rig

ZJ5013150DB rig adopts swing up type :
substructure and K type mast, one time stringing
can continuous raising. double motor single geal
tansmission driven single shait double shit Ac trequency conversion Drawworks, can reaize double stages stepless speed reawlation
improve the equipment reliablity and operaional economy. Electric drive control svstem adopts Siemens PLC and Ac freauency conyersior
technology, high efficiency, high control precision, the whole rig control system adopts the redundant heat backup mode, compatible, fault
tolerant performance is good, Supporting 2 sets of F - 1300 triplex cylinder mud pumps, can improve driling speed, ensures the bit reliable
high-speed rotation, prolong the service life of the drill bit and improve driling efficiency.

1.Give full play to the advantage of advanced
diaita Acfrequency conversion
electric transmission, and uses the machine. electricity. liquid
gas, digital control integration design, improve the control accuracy, simplifies the structure of drilling rig.
2. Equipment on the floor is installed at low position and overall hoisted. Reducing the workload of aerial work and improve the security
3.lectric transmission adopts vector frequency conversion dfive system and realize the fuly digital control operation, obligate interface for
remote fault diagnosis expert system, can realize the colection of control parameters and drlling parameters (signal), display, storage
printing,remote monitoring and management
4.Realizing bit pressure, driling rate, pump pressure, pump capacity to large range, high precision effectively control and greatly improvec
the driling process. Using the characteristics of frequency conversion technology, make Drawworks hover at zero speed, changed the
traditional way of driller operation.
5. The operation control system using dual PLC redundancy design, improve the reliability of the system
