BZC400CHW truck mounted water well drilling machine is a directly rotary drilling rig. This truck chassis is adopt the 6×4 or 6X6 special chassis of SINOTRUK HOWO brand, 11.00R20 steel off-road tire tread, with good off-road performance.
The drilling rig has very compact structure, The drilling rig has independent diesel engine,112kw COMMINS brand(strong power). Not only meet the drilling requirements, but also reduce energy consumption, it is very affordable.
3.This water drill rig is design principle is an advanced hydraulic cylinder for drilling, stepless lift, it can be achieved automaic drilling. it can automatically adjust the drilling speed for different geological conditions.
4.The drilling process can be achieved in pressruized drilling technology, adjust different pressure for different geological conditions, and can be viewed drilling pressure by pressure gauge. At the same time, it can adjust the drilling speed.The drilling rig can achieved fast drilling by manually, especially for soil. It can achieved different speed for different soil.
5.It has a large lifting force hydraulic main hoist, stepless lift, and to achieve release rope quickly. When upgrading heavy, the lifting speed need slow to aviod crash the turntable and wellhead board. When put down single drill pipe, operate the quick handle, it can achieved release rope quickly like mechanical hoist.
6.It has a hydraulic tool hoist, the tool hoist has large lifting force and quick lifting speed, it is both easy to loading drill tools, drill pipe and drill accessories transport, and can slide up and down with anchors, its very convenient to load and unload the drill pipe.
7.It has a hydraulic cylinder control double card board forward and backward, it makes the insurance card board closed, to achieve stuck or release the pipe joints.
8.It use integrated design of pneumatic, to achieve the BW850/2 mud pump clutch using pneumatic remote control, it has high degree of automation and easy-saving operation.
9.It is installed 4 hydraulic legs and 2 mechanical legs, every hydraulic leg rod with locknut. After leveling the rig, it can lock the cylinder use locknut. So, even if the cylinder leaks, the chassis is not instability.
10.The turntable use stir bars, internal turntable use spiral arc gear to transmission, it has large torque, it about 2 times of similar products at domestic and foreign.
11.It is installed a generator (30kw) , so that it is convenient to illuminate or work at night.
The hydraulic system use open system, the chassis and drilling rig are separately manipulated, it can avoid misuse. Winter oil heater and summer oil radiator are installed, to adapt to different seasons hydraulic oil for heating and cooling.
This drilling rig equipped with an auxiliary unloading cylinder, it can be used to promote the turntable ratchet, to achieve auxiliary unloading the drill pipe.

Second, the inspection before the operation:
1. When starting work, carefully check whether the pipelines are tightly connected to gas and water (when water is required for dust removal), especially the connection between the wind pipe joint and the wind pipe must be firm to prevent tripping and injury, and the joints are not allowed. There is a leak and water leakage.
2. Check if the oil mist is filled with oil (not too full).
3. Check whether the screws, nuts, joints, etc. of each part are tightened, and whether the various positioning is firm and reliable.

Measures for the use of the water well rig during the running-in period
1. The operator should receive training and guidance from the manufacturer, have a thorough understanding of the structure and performance of the rig, and obtain certain operation and maintenance experience before operating the machine. The product maintenance and repair instructions provided by the manufacturer are the necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the maintenance instructions and operate and maintain according to the requirements of the manual.
2. Pay attention to the working load during the running-in period. The working load during the running-in period should not exceed 80% of the rated working load, and the appropriate workload should be arranged to prevent the overheating caused by the continuous operation of the machine for a long time.
How to improve the production efficiency of hydraulic water drilling rigs?
1. After the drill bit of the hydraulic water well drilling rig is drilled into the structure, the center drilling tool needs to be replaced in time. First, you need to clean the bottom of the hole and then blow off the residue at the bottom of the hole. After the drill bit stops rotating, the drill bit in the hydraulic water well drilling rig is drilled. It is most suitable when the lifting force is slowly increased and the lifting force is just enough to lift the drill bit.
2. The drilling process summarizes the drill bits of the hydraulic water well rig. It is also necessary to pay close attention to the subsequent working conditions of the casing, to know the specific conditions of the drilling in time, to clean the drilling holes in time, and to drill the drill bit on the water drilling rig. Strong lifting is prohibited during this process.
3. There will be more residue at the bottom of the hydraulic well rig. The eccentric drill bit will be stuck by the slag and affect its collection and production. At this point, it is necessary to deliver compressed air and clean the holes again. And let the down-the-hole hammer work for a short time, the water well rig model, and then re-do the center drill lifting work.
