SWD series integrated hydraulic down-the-hole drill of Sunward Intelligent has a number of patents and has the advantages including high efficiency, energy conservation and environmental protection, strong adaptability, safety, reliability, etc. It is welcomed by customers.
(1) High efficiency
a. Unique
long drill frame structure reduces the auxiliary time for changing drill
rod and improves the work efficiency. It can be equipped with 7-12m
long rod. When the step height is less than 12m, a remarkable effect can
be obtained with the application of single drill rod.
b. Arm type structure has large drill hole coverage. One walking positioning can realize multihole drilling.
c.
Pressure of air supply system is 2.5MPa at maximum. The impactor has
high drilling efficiency and the maximum speed can reach 1.2m/min.
(2) Energy conservation and environmental protection
a.
Hydraulic system and air compressor are driven by separate engine. The
engine of air compressor driven when walking does not work, reducing
fuel consumption.
b. Equipped with cyclone and laminar two-stage dust
removal system, reducing the emission of PM2.5 when working and
improving the working environment;
(3) Strong adaptability
a. Equipped with four-support telescopic legs or floating chassis with good surface adaptability.
b.
The sliding compensation mechanism can make reliable adjustment to the
drilling frame and the working contact surface, expanding the scope of
work.
c. Complete the challenge regarding harsh working conditions
including the elevation of 5300m, 50m under water, 30 degrees below
zero...... borne by SWD series down-the-hole drill again and again, and
is stably used in all kinds of adverse working conditions, obtaining the
customer's praise.
(4) Safty and reliablity
a. Interlocking of adjustment gear and operation gear reduces the possibility of the occurrence of misoperation.
b.
The parameter of automatic anti-clamping system can be adjusted
according to the working conditions to prevent clamping and reduce the
operation difficulty.
c. Automatic rod removal device is simple
and reliable, reducing the labor intensity of the operator and improving
the drilling efficiency with high reliability.
d. Full sealed cab
prevents dust entering the cab, increasing the comfort of driver and
reducing the failure rate of electronic components.
