Water well drilling rig technology

January 17 , 2022

Water well drilling rig technology Water Well Drilling Rig Equipment drills holes in the formation. According to the drilling method and the type of drilling tool, there can be rotary drilling technology. In geological exploration and geological engineering, drilling equipment facilitates underground drilling. Small diameter and deep cylindrical holes, this is called drilling. Design different drilling and drilling depth according to drilling application. The main functions of drilling is to Obtain underground physical data, and obtain cores, cuttings, oil, water, natural gas, etc. According to the purpose of classification, drilling is generally divided into geological exploration drilling, geological exploration drilling, water well, engineering geological drilling, geothermal drilling, oil drilling, etc.

How to improve the working efficiency of a water well drilling rig

January 11 , 2022

How to improve the working efficiency of a water well drilling rig？ Working system of a water well drilling rig needs attention, since the movement system of the machine is different from the working state and working characteristics of each components. There are three important parts: rotation system, circulatory system and hydraulic system. And the system is fully configured in this way. When there are residues at the bottom of water well. The drill bit clings to the slag and affects working efficiency. At this point, you need to provide compressed air and clean the holes. Then, after running the down-the-hole hammer for a period of time, run the drilling equipment, and then perform the lifting work of the center drill again.

The Advantages of the Pneumatic Drilling compare to Water Drilling

January 04 , 2022

The Advantages of the Pneumatic Drilling compare to Water Drilling 1) The single impact power of a pneumatic drill is large, generally up to tens of kilograms or more than a hundred kilograms, which is more than ten times-dozens of times the single impact energy of the current hydraulic impactor. Therefore, from the perspective of rock crushing, the gas drill is mainly based on impact crushing rock, and the rotation only changes the location of impact crushed rock, and at the same time plays the role of auxiliary rock crushing. Therefore, the drilling efficiency depends to a large extent on the performance and quality of the down-the-hole hammer. (2) Due to the low air density during gas drilling, the pressure of the gas column in the full-hole section is much smaller than that of the liquid column, which improves the multi-directional pressure state of the rock at the bottom of the hole, which is conducive to breaking the rock and improving the drilling efficiency; But on the other hand, it requires a high flow rate to purge the bottom of the hole. Generally, it is required that the speed of the upward return air in the outer annular gap of the drill pipe must be 10-15m/s, and the hydraulic impactor of the water drill has a liquid flow when drilling. The up-return speed is only 0.8-1.2m/s, and the annulus flow velocity during small-diameter diamond rotary drilling is mostly 1m/s. Therefore, when drilling with a pneumatic DTH water well drilling rig, there is less rock powder at the bottom of the hole, which reduces repeated fragmentation of rock powder, and its drilling efficiency can be doubled. (3) The down-the-hole hammer of the air drill uses compressed air as the motive medium when drilling. After the high-pressure air passes through the impactor, the pressure around the bit is suddenly reduced, and heat is absorbed, which is very beneficial to increase the life of the bit.

Introduction of water well drilling rig crawler

December 28 , 2021

Introduction of water well drilling rig crawler  The crawler water well drilling rig is composed of a crawler track and water well drilling rig, The advanced technology prevent the track from falling off when the water well drill is turning. To improve the firmness of the crawler track and the adhesion between the crawler track and the ground, there are also supporting wheels, supporting wheels, driving wheels and rail links on the water well drilling rig site.  When cleaning the drilling rig, the sludge on the lower walking body should be cleaned at the same time. After the operation, the operator should clean the sludge on the lower walking body while cleaning the cab, if there is sludge attached to the lower walking body. It is impossible to check the related parts. Therefore, please remove these sludge and inspect and maintain the lower walking body

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

December 21 , 2021

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 fuel oil (water) level and quality, and pay attention to check the seal of the whole machine. It is found that there is too much oil and water during the inspection, and the reason should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended to add grease to the lubrication point during the running-in period (except for special requirements). 4. Pay attention to frequently observe the instructions of each instrument. If there is an abnormality, stop and remove it in time. If the cause is not found and the fault is not removed, the operation should be stopped. 5. At the end of the running-in period, the machine should be subject to mandatory maintenance, inspection and adjustment should be done, and attention should be paid to the replacement of oil. The requirements for use and maintenance of water well drilling rigs during the running-in period can be summarized as: reducing load, paying attention to inspection, and strengthening lubrication. As long as you pay attention to and implement the maintenance and maintenance of the construction machinery during the running-in period as required, it will reduce the occurrence of early failures, prolong the service life, improve operating efficiency, and bring you more economic benefits.
