Deep diesel engine DTH hard rock water well drilling machine
>> Introduction
TWD Series Multi-functional trailer mounted water well drilling rig is a efficient,multi-function full hydraulic water welldrilling rig.It is high efficiency because of having a larger torque of the turntable and is mainly used for water well in industry and agriculture, national defense building foundation, geological exploration, geothermic well and other foundation working, it is popular at home and abroad.
>> TWD series trailer mounted drilling rig can drilling in all kinds formations by mud drilling in soft formation and air DTH hammer in rock drilling,DTH Hammer is applied in rock drilling, slag is discharged by air pressure and the offstage efficiency is ten times than traditional rotary drilling.
>> TWD series deep water well drilling rigs, in cutting drilling or rotary drilling can be operated in unconsolidated layer, and the slag can be discharged under by mud, the impact drilling operation can also be adopted and slag can be discharged by pressure air, the hydraulic water well drilling rig suitable for drilling complicated geological conditions.
>> Characteristic
 | 85KW,4Cylinder,water cooling Diesel Engine Famous Brand Hydraulic System |
| Big Torque & Fast Rotation Speed |  |
 | >> Centralized control console is suitable for each manipulation and control. Rapid pulling and lifting reduce the auxiliary time and enhance the work efficiency.
>> The main drive system, the transfer case, gearbox, double-winch unit, mud pump, turntable,drilling tower, feed system are set up on the chassis.
>> It's a hydraulicrotary drilling rig with directional circulation. It can equipped with BW450 mud pump which adopts the slurry as the washing fluid and can drill on clay, sand and rock if it is equipped with suitable drilling bit.
>> The power of drilling rig comes from a diesel engine,High power diesel engine drives the large displacement high pressure plunger pump and it is characterized by powerful dynamic and stable performance.
>> The rotary head,have two gear,rotation speed is 0-80 and115rpm stepless adjustment and the drilling rigs with high rotary torque.
>> The pulling force can be regulated and controlled, which adapt the machine to deep hole drilling.
>> It can set up a generator which is convenient to welding or illuminate for work at night.
>> Main winch are available on the rig so it is high efficiency when the rig drill on mud rock and on the weathering formation. |
