Product Description HF-44A intelligent control core drilling
rig is one new design diamond drill bit and alloy drill bit core
drilling equipment, it is researched and designed by our factory
expert together with famous NWPU expert.It also can be used for
engineering geological exploration ,shallow petroleum and natural
gas mining ,mine tunnel ventilation ,drainage,water well drilling
and large diameter foundation pile construction, it has intelligent
control,safe ,efficient comfortable and innovative
features.1.Application of fully digital electrical control system,
can set the torque limit value according to the torsional strength
of drill pipe as the machine is working, when the load is too large
or sudden increase, it can warning earlier. All the data appear on
the screen intuitively. Workers can take corresponding actions in
advance according to the informations, the phenomenon such as
sticking, sudden increase of load.2. Drilling rig's rotary is
driven by dc speed regulating motor, rotary speed can realize
stepless speed change in a certain range. Can regulate freely
rotary speed according to the working condition of drilling rig.3.
Drill winch is driven by ac frequency conversion motor, the control
system is separated from its host, hoisting speed and realize
stepless speed, effectively improve the efficiency of construction,
and avoid the personal injury accidents when put up drilling
tools.Product ParametersDrilling depthCore drilling
