300m Truck-Mounted Water Well Drilling Machine

Application

YKW-T300 truck mounted water well drilling rig, equipped with proper drilling tools, can drill in Quaternary strata such as clay layer, sandy soil layer, weathered rock and bedrock. This machine is reasonable in design, complete in matching and superior in performance. It can realize various drilling processes (such as mud circulation, air foam drilling, pneumatic DTH hammer drilling, gas lift reverse circulation drilling) to adapt to different strata.

Main Characteristics

YKW-T300 truck mounted water well drilling rig is equipped with HOWO 6x6 chassis; the power station, double winch unit, mud pump, rotary table and drilling tower are installed on the chassis, which is convenient for transportation and good mobility.

1) The drilling rig is equipped with four hydraulic legs, which can act simultaneously or independently, which is convenient for rapid leveling of the drilling rig. Moreover, the two rear legs can be extended horizontally, which improves the stability of the whole rig.

2) The rotary table is of lever type, with spiral bevel gear transmission inside, which has stable transmission and large torque transmission.

3) The rig is equipped with a large displacement reciprocating plug pump produced by well-known manufacturers in China, with large flow rate and high pressure, which can ensure the smooth progress of drilling construction.

4) The main and auxiliary hoists have large lifting force, which can meet the needs of normal drilling, and have the ability to deal with general well accidents.

5) This machine is equipped with an auxiliary rod unloading oil cylinder, which is used to push the ratchet of the rotary table to rotate in reverse direction. The first thread of the drill pipe joint is removed, and then the rotary table is used to reverse the rod unloading. This greatly reduces the labor intensity and improves the service life of the machine parts.
