Product Specifications of DFHC-200 Water Well Drilling Rig:

1, DFHC-200 truck mounted drilling rig adopts hydraulic electric technology combined with positive

and negative circulation power head drill, mainly consist of the drill tower,hydraulic power head,

sand pump, water pump,hydraulic cylinder-wire rope pulley block  hoisting mechanism, auxiliary

hoist,drill pipes, drill pipe removal device,hydraulic station,power distribution cabinets, operating 

mechanism and the generating set, etc.All parts are mounted on special movable chassis.

2, Drilling rig’s power head are driven by electric motor or hydraulic motor ,sand pump and auxiliary 

hoist are driven by a electric motor. Operating mechanism is the combination of hydraulic, electric

and mechanical manipulation.Main way of DFHC - 200 drilling method is power head 

rotation-reverse circulation mud drilling;If equipped with appropriate drilling tool, it can also 

adapt to other methods,like air compressor drilling or foam drilling. 

3, At the beginning of drilling,it can use pressurized structure to press the drilling tools, in order to 

improve the shallow hole drilling efficiency, with the hole goes deeper, when drilling tools’ weigh 

are enough, you can drill freely or reduced pressure drilling.

4, Hydraulic cylinder - wire rope pulley block is used to raise and fall the drilling tools,as well as force

the pressure,auxiliary hoist is used for lift the drilling pipe, also can be used to lift other tools,etc.

Application 

Mainly applicable to the quaternary loose bed, gravel layer, rock layer for industrial and 

agricultural water well drilling, also can realize foundation piling holes of various architectural 

base and other purposes.

Characteristics

(1) Used for water well drilling and engineering piling holes, functional with good performance;

(2) Reasonable layout , compact structure, good mobility, convenient and quick transitions;

(3) Integrated with the mechanical, hydraulic and electric technology, guarantee the good 

performance, easy to manipulate, and environment friendly;

(4) Truck engine power generation technology, uses microcomputer control, self-developed 

patented technology;

(5) The platform hydraulic leveling, with hydraulic lock, to ensure the borehole verticality.

(6) Uses single hydraulic cylinder - wire rope pulley block hoisting mechanism, operation more 

convenient, improves the efficiency, with pressure increased and reduced drilling function;

(7) Adopts the modular design, the maximum meet the personalized needs of customers.At the 

same time, also greatly improve the convenience of maintenance.

Parameters of  DFHC-200 Water Well Drilling Rig

How to choose a suitable drilling rig?

1. What will you do using drilling rig? 

---For water project, core sample, soil test, mineral prospect or others?

2. The depth you need?

---For water well, generally, 30-200m. For core sample, 30-600m, even more. 

3. Any requirements to hole diameter?

---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.

4. Working land condition?

A. soil, sand, weathered land, etc. soft stratum.

B. soil, sand, soft and hard rock stratum, mixed one. 

C. Mainly hard rock, like granite.
