Water well 800m Hydraulic Mineral Exploration Drilling Rig
Product information:
JDL-400 drilling rig is a water well drilling rig that mix mud drilling rig and air drilling rig in one equipment. It adopts AMT manual automatic transmission, 10 grade forward fears, and 2 grade reverse gears. Positive and negative switching is sensitive and convenient. Compared with the hydraulic transmission, the its transmission efficiency can be doubled, and the power consumption is reduced by 35%, which make the machine more efficient and energy-saving.
Main feature
1. The rig uses an automatic gearbox, which has a wide range of speeds (14-650rpm), can output big torque( Max.13400N.m), and easy speed control.
2. The rig adopts a long-stroke double-speed mechanism,the power head stroke reaches 3400MM to increase the drilling efficiency and reduce the occurrence of plugging and drilling accident.
3. The rig uses double oil pumps to supply oil. When feeding, it uses a single pump. When lifting pipes, the double pumps are combined. The power loss is low and the auxiliary time is short.
4. The rig adopts the main function of mechanical transmission, compared with hydraulic transmission, the power loss of the rig is small, and the drilling cost is lower.
5. The drilling rig reserves part of the functional interface in the hydraulic system so we can expand the function according to the technological requirement of different users.

1. Walking part:
Driven by high-torque plunger motor, using 43*135*400 steel tracks, the moving speed can reach 2.5km/h. The power is strong and durable.
2. Power part:
76kw turbocharged diesel engine in the cloud is adopted, and the reserved power reaches 15%, which is more suitable for plateau construction.
3. Hydraulic part:
The hydraulic system is powered by the 32/32 dual pump, which mainly realizes walking, tower lifting, drill pipe feeding, drill pipe lifting and so on.
