Application
JK300 crawler deep hole water well drilling rig is a
new,highly-effective,energy-saving ansd multi-functional hydraulic
drill and the water well drilling rig is specialized in drilling
hole for water well drilling, rock blasting,well,monitoring well,
geothermal air conditioning hole, grouting hole of the hydropower
cofferdam, grouting hole for dyke seepage control and grouting hole
for base enforcement, surface mining,anchorage,national defense
project and other drilling operations, in addition, the water
drilling machine adopts the process of down-hole impact and breast
wall drilling with casing following, which can effectively solve
the technical problem of difficult hole-forming in the
unconsolidated layer. The water borehole drilling rig is equipped
with hydraulic motor rotation with a high power, propulsion and
lifting of cylinder and down-hole hammer with high blast pressure,
to realize high effectiveness of drilling footage and low energy
consumption. the JKS300 drilling machine can drilling by DTH air
drilling rig and mud drilling.
Characteristics
1. The drilling rig can use DTH Hammer drilling and mud drilling.
2. Centralized control console is suitable for each manipulation
and control. Rapid pulling and lifting reduce the auxiliary time
and enhance the work efficiency.
3. The pulling force can be regulated and controlled, which adapt
the machine to deep hole drilling.
4.92kw Cummins engine drives the large displacement high pressure
plunger pump and it is characterized by powerful dynamic and stable
performance.
5. The rotary head, it’s rotation speed is 0-160rpm stepless
adjustment and the rotary torque is 7500Nm.
6. With lifting force of 1.5T, the auxiliary winch is used for
auxiliary lifting and casing.
7. Long strike hydraulic supporting leg can be use for
transportation, loading and unloading of the drill automatically
without the help of crane.
8. The Hydraulic auxiliary functions are easy and efficient for
guide extension, boom swing, boom lift, guide tilt and guide dump.
9. Competitive in price, low cost of maintain.
