Supply deepwater drilling rig rotary drilling equipment electric irrigation drilling equipment

 、 Bz-200 hydraulic drill is suitable for general survey exploration, geophysical exploration, road and building exploration, blasting hole drilling and other drilling projects
Alloy, diamond and composite bits can be selected for drilling according to different bottom layers
It can drill grade 2-9 sandy clay and rock stratum

2、 Features of bz-200 hydraulic drill
1
It has oil pressure automatic feeding mechanism to improve drilling efficiency and reduce workers' labor intensity

2
The ball clamp clamping mechanism is used to replace the chuck, which can reverse the rod without stopping the machine, which is convenient, safe and reliable

3
The winch is equipped with cage to form a double-sided supporting star wheel structure, which can withstand strong impact
4
Four groups of bearings of the vertical shaft box are positioned to ensure that the gyrator is rigid enough to deal with complex geological conditions such as gravel layer and pebble layer
5
The machine adopts the taper clutch of national advanced technology, which has the outstanding characteristics of large transmission torque, convenient operation and maintenance free
