NL 350 Pneumatic Drilling Rig Advantages
1. Drill max 350m depth, 200-550mm diameter
2. SINOTRUCK 6X4 tuck chassis ,drilling rig ,mud pump ,generator ,diesel engine etc all components installed into the truck ,easy to move to anyplace
3. Drilling rig diesel engine use 120KW DEUTZ ,very powerful and excellent quality
4. Mechanical top head driving rotary head ,it has advantages of both hydraulic power head and turntable type
5. Drilling way can be mud positive circulation drilling, air lift reverse circulation drilling ,mud DTH hammer drilling and air DTH hammer drilling ,different drilling way choose for different stratums ,especially ,mud DTH hammer drilling is our new technology ,use mud pump power for DTH hammer drilling, with very high efficiency and save much oil consumption and save too much cost
6. Simple structure ,mostly mechanical trasmission ,low failure rate and low maintenance cost
7. Big torque :max 10000NM, big lifting capacity :20T ,very strong and big capacity machine
8. Mainly used for deepwell and large diameter well drilling, also used for pile foundation in some projects
Water pressure propulsion, cost saving, drilling speed, second only to the air compressor, the drilling speed of this rig, many times by the drill collar, hydraulic, mud pump rig!
What aspects should we pay attention to in the drilling process ?
Bit plays a very important role in the drilling of water well drilling rig, but the quality of a bit directly affects the efficiency and quality of water well drilling. Therefore, in the selection process, we should pay attention to the selection and use of lower bit. When we are operating the drill bit, we must pay attention to several aspects in order to better production and operation.
After the drilling structure of the drill bit of the water well drilling rig is drilled, the central drilling tool needs to be replaced in time. First, the hole bottom needs to be cleaned, and then the residue at the hole bottom needs to be blown away. After the drill bit stops rotating, the drilling tool in the water well drilling rig can be lifted up slowly. When the lifting force is just enough to lift the drilling tool, it is the most appropriate.
