Match a suitable Air Compressor for Drilling Rig machine

September 23 , 2022

In order to achieve high perforation efficiency, drilling rigs equipped with high-pressure air compressors have gradually taken the mainstream. The drilling efficiency of a drilling rig is critical. Because the perforation efficiency of the drilling rig mainly depends on the down-the-hole hammer, the air consumption of the hammer is determined by its design structure. With the increase of wind pressure and air volume, the output power of the hammer doubles, and the drilling speed also doubles. improve. That is to say, when a high-performance drilling rig and a high-efficiency hammer are selected, there must be an air compressor with corresponding air pressure and air volume to ensure that, otherwise, the drilling efficiency of the same drilling rig will be different due to the different performance parameters of the air compressor. make a big difference. In practice, this situation often occurs: there is already an air compressor, which needs to be matched with a down-the-hole drilling rig; or there is already a down-the-hole drilling rig, which needs to be matched with an air compressor. The factors considered are mainly the matching of the down-the-hole drilling rig and the air compressor. Each DTH drilling rig has its specific technical parameters and requirements...

Matters needing attention in construction of DTH drill bits

September 19 , 2022

Matters needing attention in construction of DTH drill bits 1. When working in different rock formations, choose different types of down-the-hole drill bits, axial pressure and rotational speed according to the hardness of the lithology. 2. During the perforation operation of the down-the-hole drilling rig, the operation must be carried out in accordance with the principle of matching the three elements of perforation (wind pressure, axial pressure, rotational speed) and the parameters recommended by the drill bit sample. 3. Before the drill bit goes down the well, please check the appearance of all parts, and verify whether the end face of the drill bit thread is consistent with the factory number on the drill bit packing box and certificate to prevent counterfeiting. 4. The drill bit should be reasonably stored on the DTH drilling rig to prevent dust and other debris from entering the drill bit. 5. When replacing the DTH drill bit, make sure that there is no dust inside the drill tool, the air outlet is unobstructed, the thread is oiled, and the drill bit can be used after connecting the drill bit by means of lifting and rotating. 6. Before replacing the new drill bit, carefully check...

What rules should be followed during the Drilling process ?

August 26 , 2022

What rules should be followed during the Drilling process ? 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 the machine, be sure to put the joystick in a stop state, turn off the engine, release the residual hydraulic pressure through the operating handle, and then remove the key. 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...

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...
