HJi800 crawler-mounted drilling nig can drill in all kinds of formations by mud drilling in soft formations and air DTH hammer in rock drilling. DTH Hammer is applied in rock drilling, slag is discharged by air pressure, and the off-stage efficiency is ten times that of traditional rotary drilling.HJi800 deep water well drilling rigs, in cutting drilling or rotary drilling can be operated in an unconsolidated layer, and the slag can be discharged under mud, the impact drilling operation can also be adopted, and slag can be discharged by pressure air, the hydraulic water well drilling nig is suitable for drilling complicated geological
conditions
>> Characteristics
>> The drilling rig can use air DTH Hammer drilling and mud drilling.
>> The central 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, and double-winch unit. mud pump. tuntable.Dripping tower, feed system is set up on the chassis>> it's a hvdrauicrotary dhiing nig with directional circulation. It can be equipped with a BW450/BW850 mud pump, which adopts the slurry as the washing fluid and can drill clay, sand, and rock if it is equipped with a suitable drilling bit.
>> The power of drilling comes from a diesel engine, a 151 kW Cummins engine drives the large displacement high-pressure plunger pump, and it is characterized by powerful dynamic and stable performance.
>> The rotary head has two gears. The rotation speed is 65-130 rpm, and the rotary torque is 6500-8500Nm
>> The pulling force can be regulated and controlled, which adapts the machine to deep hole drilling.
>> The main drive of the rig is hydraulic, and the four hydraulic legs and drilling tower are hydraulic-controlled. The transfer case and mud pump clutch system are also hydraulic-operated
>>The Hydraulic auxiliary functions are easy and efficient for auxiliary extension.
