The drill bit plays a pivotal role in the drilling process of water well drilling rigs. The quality of a drill bit directly affects the efficiency of water well drilling and the quality of the hole, so we need to pay attention to the selection and use of the drill bit. During the drilling process, the operator should pay attention to the drilling usage of the drill bit to make the drill bit better for production operations. Several aspects that need to be paid attention to in the drill bit of the water well drilling rig: 1. After the drill bit of the water well drilling rig is drilled into the structure, the center drilling tool needs to ...

The invention and development of the pneumatic water well drilling rig is a major revolution in drilling technology. It has changed the traditional way of cutting and grinding rock, breaking the rock into volume, greatly improving drilling efficiency and adaptability to hard and complex formations. Its remarkable technology Economic benefits are regarded as one of the symbols of modern drilling technology and measurement of drilling technology, and are valued by the drilling industry at home and abroad. Pneumatic down-the-hole hammer drilling mainly begins with drilling blasting holes, water well bedrock holes and geological exploration h...

Operation steps of Connecting the Drill Pipes 1. When a drill pipe needs to be added to the depth of one drill pipe after drilling, first stop advancing, then stop rotating, and turn off the cooling water; 2. Operate the gripping handle to make the gripper clamp the drill rod, and open the fine adjustment flow valve (right-handed); 3. The gyrator reverses, and at the same time, retreat the feed cylinder to rotate the water braid shaft and the drill rod away; 4. Stop the rotation and operate the fast forward and retreat handle to the fast backward position, so that the chuck can be quickly retracted into place; 5. Connect the drill pipe to...

Inspection before drilling 1. Check the oil level and coolant of the water well drilling rig, and whether the hydraulic oil of the drilling rig is sufficient. 2. Check whether the link screws of each part of the drilling machine are tight. 3. The lubricator is added in time according to the use situation (the use of secondary pollution engine oil is prohibited). 4. Check whether the left and right chains are strenuous at the same time and the adjustments are consistent. Drilling process 1. Drive the water well drilling rig to a predetermined position, open the outriggers, level the drilling rig, and connect the air pipe. 2. Connect the im...

Core drilling rigs are widely used in geological survey exploration, geophysical survey; road and bridge construction survey; geotechnical engineering blasting hole, grouting hole, structural quality inspection of concrete engineering, agricultural water well drilling and other drilling construction. The core drilling rig is mainly composed of power, reducer, water pump, clutch and gearbox, vertical shaft box, winch and drilling tower. The most important thing in operating the core drilling rig is experience and skills. During the construction process, when the drill pipe bit is lowered into the hole, the operation and control are complet...

The truck-mounted drilling rig is specially designed for field drilling and convenient transportation. The vehicle-mounted type integrates the truck chassis, drilling rig equipment, air compressor, mud pump, etc. The structure is reasonable and the operation is simple. After arriving at the construction site, there is no need for additional crane loading and unloading, which greatly facilitates the drilling work and saves manpower and material resources. 1. The truck chassis can be selected from Chinese brands such as Sinotruk and Dongfeng, or other brands can be selected according to customer requirements 2. The drilling rig can choose P...

1.Prolonged the drill bit working life, and make the drill rigs less affected by the climate; Improved the speed of returning slag; During the drilling process , there is no need to use a mud pump, and there is no need to spend a lot of time to maintain the mud pump; In the process of drilling, the aquifer is not easy to be blocked by drilling fluid, and the water volume is intuitively observed; The torque used for drilling is much smaller than that for rotary drilling, and the rotary speed is also very low, generally 10-30r/min; The drilling rate is fast in the consolidated rock, the air foam DTH hammer drilling in the sandstone formati...

2. Understand the machinery (1) Before operating the machine. Read the water well drilling rig operation manual and construction safety manual first. (2) Be able to operate all equipment on the machine: understand the functions of all control systems, instruments and indicators; understand the rated torque, rated pressure, main winch lifting capacity, maximum drilling diameter, maximum drilling depth and operating space height; Living in rain, snow, ice, gravel and soft soil will change the working ability of the machine. (3) Read and understand the manufacturer’s operating instructions before preparing to start the machine. If the ...

1. Comply with the computer procedures and safety inspection procedures (1) Understand water well drilling rigs, action rules, safety protection regulations, and understand the performance and specifications of water well drilling rigs. 1. Know the rules (1) Do not carry people on the machine. (2) Understand the performance and operating characteristics of the machine. (3) When operating the water well drilling rig, do not let irrelevant personnel approach, and do not modify or dismantle any parts of the machine (unless it is needed for maintenance). (4) Keep bystanders or unrelated persons away from the work area. (5) Whenever you leave ...
