ZJ20/1350 Oil Drilling Rig
Introduction
2000m series oil drilling rigs are designed and manufactured for exploiting oil and gas well, coalbed methane well, geothermal well, shale gas well and so on. They are characterized by simple structure, easy operation, long durability. The main models are as follows: ZJ20/1350, ZJ20/1350DJ (AC drive), ZJ20/1350DZ (DC drive),ZJ20/1350DB (AC VFD).
Main features
1.Mechanical transmission
2.Power: diesel engine+ decelerator
3.Speeds in gearbox become 4 forward +1reverse by gear transmission
4.Output shaft of gearbox transmit the power to drawworks by chain
5.Reasonable distribution of gears, high use ratio of power
6.ZP175 rotary table
7.Gear-shift of gearbox is controlled by pneumatic system
