How to maintain the Buttery of the Drilling Rig machine

August 22 , 2022

The requirements for the correct use of the battery are as follows: 1. Do not use the starter continuously. The starting time of the water well drilling rig should not exceed 5 seconds each time. If it fails to start normally once, it should be stopped for 15 seconds before starting the second time. If the start is unsuccessful for three consecutive times, the cause should be found out and other faults of the water well drilling rig should be eliminated before Start the engine. 2. In severe cold regions, the battery should be insulated in winter. 3. When installing and handling the battery, it should be handled with care, and it should not be knocked or dragged on the ground. The battery should be firmly on the drilling rig to prevent vibration and displacement. Battery maintenance requirements for water well drilling rigs are as follows: 1. Always remove the dirt on the surface of the battery, and remove the oxides on the electrode piles and wire clamps in time. 2. Always unclog the vent hole on the filler cap. 3. The discharged battery should be charged within 24 hours. 4. The used vehicle battery should be recharged every two...

Principles and advantages of down-the-hole drilling rigs

August 20 , 2022

Down-the-hole drilling rigs can drill holes in rocks of medium hard or above (f≥8). Like the rock drill, it has the process of impacting, rotating, discharging and advancing the rock drilling hole. The difference is the impact mechanism of the down-the-hole drilling rig. The extension and continuous advancement. The down-the-hole drill is named after the impactor dives into the hole, and has the following advantages in use: 1. There is no energy transmission loss, the impactor directly acts on the drill bit, no drill pipe is required to transmit impact energy, and the drilling speed is not affected by the depth of the hole. 2. The hole is straight, the drill pipe has high rigidity, does not bear impact force, only transmits torque, and the transmitted shaft pressure is very small. During decompression drilling, there is no need to transmit shaft pressure at all, so the drill pipe is not easy to bend and deform. The blasthole is straight and smooth, especially when there are cracks in the rock, the bevel is inclined or the rock hardness changes, it is better than other drilling methods. 3. The slag discharge is clean, and the motive medium can flush the blast hole...

How to choose a good DTH Hammer

August 06 , 2022

A good DTH hammer should have two indicators: long tool life and high rock breaking efficiency. Previous studies have shown that it is not only the impact frequency and impact energy that affect the performance of the hammer, but also has a close relationship with the weight, shape, stroke size and impact speed of the hammer. On the same hammer, the performance parameters are also interrelated and restricted. When determining the parameters of the hammer, they must be linked, and the matching relationship must be selected. However, the main factors affecting the speed of percussion drilling are impact frequency, impact energy, impact mode and transmission. Proper and timely maintenance can prolong the life of DTH hammer components and reduce operating costs to a large extent. Clean the parts of the DTH hammer in time. In many cases, the outer casing is worn or the performance of the hammer is reduced due to the wear of the internal parts. At this time, the DTH hammer needs to be repaired and more detailed inspection is required. If all parts are in good condition, you need to apply lubricating oil and install them correctly according to the assembly diagram. However, in order to...

How to use the Drill Bit properly

July 26 , 2022

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 be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole is blown clean. The tool is slowly lifted up, and it is most suitable when the lifting force is just enough to lift the drill tool. 2. The drill bit of the water well drilling rig is summarized during the drilling process. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the...

Advantages of the Tricone Bits

July 18 , 2022

At present, whether in domestic construction or abroad to contract water well projects, the drilling technology of roller cone bits is generally adopted, especially in the construction of deep water wells and geothermal wells. From the field of use of roller cone bits in recent years, it has been extended to pile foundation construction, trench-less engineering construction, coal mine gas discharge well construction, the application scope is constantly expanding, and the social and economic benefits are very significant. Engineering practice has proved that the use of roller cone drilling technology has no special requirements for formation and groundwater conditions, and has the characteristics of good adaptability and wide application range, and should be vigorously promoted and applied. Compared with the general barrel drilling and core drilling efficiency, the drilling process of the roller cone bit is one to several times higher, and the life of the bit is also long. Dozens of meters to 100 meters are generally not a problem, the cost is low, and the one-time investment is not large. During the drilling process, the pure drilling time is increased and the auxiliary time is shortened (sometimes drilling is carried out only once in several shifts). The drilling...

Classification of water well drilling rigs(VI)

July 05 , 2022

Second, according to the type of drive device Water well drilling rigs can be divided into the following categories according to the type of driving equipment: 1. Electric-driven drilling rig: It is mainly powered by an AC motor to drive the drill pipe to the turntable. It is equipped with a water tap, a kelly, a lifter, etc., and the pressure and pressure are realized by its own weight and a winch. 2. Mechanically driven drilling rig: It is mainly powered by a diesel engine to drive the drill pipe to the turntable. It is equipped with a water tap, a kelly, a lifter, etc., and the pressure and pressure are realized by its own weight and a winch. 3. Hydraulic drilling rig: The power head is provided with hydraulic power to drive the drill pipe. The power head is both a faucet and a lifter. It functions as a drawworks when raising and lowering the drilling tools, and functions as pressurization and decompression when drilling.
