◎BZC300DDF6×4IIIThe car mounted water well drilling rig is a positive circulation rotary drilling rig. The drilling rig uses Dongfeng 6The chassis of the 4 × 4 specialized drilling rig is DFS1251GL18, with emission standards of National III, and adopts 11.00R20 steel wire off-road tread tires with good off-road performance.

◎The drilling rig has a compact structure and the chassis is produced by independent Yuchai Co., Ltd., model YC6J180-33Diesel engine, emission country three, with a power of 132kw/2500rpm and strong power.

◎The drilling rig uses an independent diesel generator set as power during drilling, and the mechanical hoist and turntable work simultaneously through motor transmission;

◎The drilling rig is equipped with a mechanical double winch unit, and the main and auxiliary hydraulic winches have the characteristics of high lifting force and fast lifting speed, which can meet the needs of normal drilling and have the ability to handle general wellbore accidents.

◎The hydraulic cylinder controls the advance and retreat of the wellhead card to close the safety card, thereby achieving the clamping or releasing of the drill pipe joint.

◎Pneumatic integrated design, realizing pneumatic remote control of BW850/2AMud pump clutch, high degree of automation, easy and labor-saving operation.

◎The drilling rig is equipped with 4Only hydraulic support legs, two mechanical support legs. Each hydraulic leg cylinder piston rod is threaded and equipped with a locking nut, which can be used to lock the cylinder after the drilling rig is leveled. In this way, even if the oil cylinder leaks, the chassis will not become unstable.

◎The rotary table is a lever type, with a spiral arc gear transmission inside, transmitting a large torque, which is 2 times higher than similar drilling rigs at home and abroadTwice.

◎The hydraulic system adopts an open system, with separate loading and unloading operations to avoid misoperation. Equipped with a winter oil temperature heater and a summer oil temperature radiator,To adapt to the heating and cooling of hydraulic oil in different seasons.

◎This drilling rig is equipped with an auxiliary unloading rod oil cylinder, which is used to push the ratchet teeth of the rotary table, remove the first thread of the drill pipe joint, and then reverse the unloading rod with the rotary table to prevent damage to the drilling rig gearbox caused by impact force during unloading.
