Advantages and adaptability of Tricone Bit

2022.08.12

At present, whether in domestic construction or overseas contracting of water well projects, roller cone drilling technology is generally used, especially for deep water wells and geothermal wells. Judging from the field of roller bit use in recent years, it has been extended to pile foundation construction, trenchless engineering construction, and coal mine gas drainage well construction. The scope of application is continuously expanding, and the social and economic benefits produced are very significant. Engineering practice has proved that the use of roller bit drilling technology has no special requirements on the formation and groun...

Water well drilling rig machine Engine starter usage and maintaining

2022.08.06

The starter is generally composed of three parts: a DC motor, a transmission mechanism and an electromagnetic operating mechanism. The correct use and maintenance methods of the starter, in order to extend the life of the starter, and ensure that it can work quickly, reliably, and safely, the correct use and maintenance requirements for the starter of the water well drilling rig are as follows: 1. The starter is designed for short-time high-current operation, and its output power is also the maximum power. Therefore, when using the starter, the working time should not exceed 5 seconds each time, and the repeated start must be separated by...

Introduction of the Drill Rods

2022.07.29

Introduction of the Drill Rods Seamless alloy steel pipes are made into drill pipes after several processing steps. First of all, through the processing of the steel pipe thickening process, the outer surface of the light pipe is bent inward, and the wall of the steel pipe is thickened. The next step is threading and plating with copper for strength. A non-destructive quality control inspection is then carried out, followed by welding of the steel pipe body joint. Then, the tube undergoes a welding heat treatment and a welding finish to eliminate welding residual stress. Several other tests are performed on the finished steel pipe before ...

How to Maintain the water well drilling rig during the run-in period.

2022.07.29

How to Maintain the water well drilling rig during the run-in period. 1. Pay attention to the working load during the running-in period. Generally, the working load during the running-in period should not exceed 80% of the rated working load, and a suitable workload should be arranged to prevent the occurrence of overheating caused by long-term continuous operation of the machine. 2. Keep the machine clean, adjust and tighten loose parts in time to prevent the loose parts from aggravating the wear of the parts or causing the parts to be lost. 3. Pay attention to frequently check the lubricating oil, hydraulic oil, coolant, brake fluid and...

How to use the Drill Bit properly

2022.07.26

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 ...

Advantages of the Pneumatic Drilling

2022.07.15

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

2022.07.05

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...

Water Well Drilling Rig Operating Instructions

2022.06.25

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...

Introduction of the Core Drilling Rigs

2022.06.17

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...
