Product Specifications of DFC-350A Water Well Drilling Rig:
1.DFC~350A truck mounted drilling rig is designed by our engineers; it adopts
truck mounted and is a rotary drill rig.
2.The truck chassis adopts the 6X4 special crane chassis of brand
DONGFENG TRUCK, the
main transmit,transmission power, gearbox, sets of windlass, mud pump, sewage
pump,mast are set up on the chassis.
3. This rig is a rotary drilling rig with directional circulation,
which is equipped with BW850/2A mud
pump, It adopts the slurry as the washing fluid, it can drill on
clay, sand and rock if it is equipped
with a good drilling bit.
4. The power of drilling rig comes from the NC6110ZG17~20(115kw)
independent engine, the rig setups distribute implement and hydraulic system.
5. We can upset the spare electric engine and clutch implement
according to client's requirement, so that the rig can work with diesel engine or electric engine.
6. The adding pressure device is hydraulic, so it has a high
efficiency when the rig drill on mud
rock and weathering formation through using the adding pressure implement.
7. The master driving of rig is mechanical, the four jacks and mast
are hydraulic operated.
Distribute box, sewage pump, master driving clutch system are air operated.
