Water Well Drilling!!KW20 High-Effect Hydraulic Geothermal Water Well Drilling Rigs (depth 200m,diameter:115-254mm)

KW series water well drill rig is a kind of high efficient multi-purpose drilling equipment, it is mainly applied to drill water wells, agricultural irrigation wells, the ground source heat pump wells and other uses on well hole, especially applicable to water-intake engineering in mountain area and rock stratum. The drill can work on different tratums, and the biggest drilling diameter is 300 mm.

Application:

1.Geological exploration;engineering geology investigation and kinds of survey hole in concrete structures.

2.Diamond bits,hard metal bits and steel-shot could be selected to different layers.

3.The drilling depth which is 25m or 30m must be suitable for the final hole diameter 115mm or 254mm.The drilling depth could not exceed its 110%.

Feature of the drill:

1.Easy operation and high efficiency as the hudraulic feeding be taken.

2.As the ball type chunk and the driving rod, it can complete no-stopping rotating while the spindle relife.

3.The pressure indicator of bottom hole can observe and control the well conditions easily.
