Hydraulic Core Drill Rig Machine Introduction

June 13 , 2023

The core drilling rig is a kind of drilling rig suitable for cutting large areas in mountainous terrain or construction in forest areas. It has the characteristics of modular design, easy disassembly and assembly, high drilling efficiency, convenient transportation, low cost, and environmental protection. Capable of drilling in most cases to depths in excess of 350 meters in the HQ and over 500 meters in the NQ formation. The principle of the core drilling rig is roughly the same, and the main components are the drill rig, drill pipe, drill bit, etc. Power is provided by the drilling rig to drive the drill pipe and the drill bit to drill in to obtain deep core samples. According to different depths and formations, corresponding to different types of drilling rigs, XY-100 is a commonly used model. The lifting ring of the core drilling rig is connected with the ring seat with a pin shaft, the ring seat and the hook rod are welded into one body, the cylinder body and the hook body are connected with the left thread, and a stop block is used to prevent the thread from loosening. The hook body and cylinder can move up and down...

Small Hydraulic Core Drilling Rig

June 05 , 2023

1. Features of hydraulic core drilling rig 1-1. Adopt 53×59 hexagonal active drill pipe, which has strong rigidity and large transmission torque. 1-2. The machine adopts a taper clutch, which has the outstanding characteristics of large torque transmission, convenient operation and maintenance-free. 1-3. The planetary gear of the winch increases the modulus and installs a support frame, which greatly improves the hoisting and braking capabilities of the winch. 1-4. The four sets of bearings of the vertical shaft box are positioned to ensure that the gyrator has sufficient rigidity to cope with complex geological conditions such as gravel layers and pebble layers. 1-5. The same type of machine in the country is the first to be equipped with an integrated mud pump with a flow rate of 160L/min, which has the characteristics of energy saving, compact structure, and light movement. 2. Application range of hydraulic core drilling rig Geological survey and exploration, road and high-rise building foundation exploration, and various concrete structure inspection holes, river embankments, subgrade grouting hole drilling and direct grouting, civil core and geothermal central air conditioning, etc.

How to Maintain the Drilling Rig Machine

May 23 , 2023

How to Maintain the Drilling Rig Machine 1. Before the construction of the drilling rig, it is necessary to do a good job in the maintenance of the equipment: 1. Check the oil balance and oil quality of each fuel tank 2. Check whether the gear lubrication of each reducer is completed 3. Check for oil leakage 4. Check the flexibility of the lifter and the quality of the internal butter 5. Check whether the parts are loose or rusty 6. Fill the drill pipe puller with butter before each shift 7. Pay attention to whether the circuit relay is embrittled in time, and prepare replacement parts as soon as possible 2. Mid-to-late maintenance schedule 1. The initial maintenance time of the diesel engine is 100 hours; after that, it is maintained every 250 hours. Replace the oil filter and oil. 2. The gear oil should be replaced every 500 hours; the gear oil in the large box should be replaced every 1000 hours. 3. The hydraulic oil is filtered every 500 hours, and all are replaced in the first 1500 hours, and replaced every 2500 hours thereafter.

What drilling methods does the drilling rig have?

May 23 , 2023

What drilling methods does the drilling rig have? First, as far as the working principle of the drilling rig is concerned, there are mainly three drilling methods. 1. The down-the-hole drilling method needs to be used in conjunction with an air compressor. it’s a good way to rock 2. Mud pump rotary drilling is a more economical drilling method, ideal for soil, sand and clay formations, for rocks, the drilling speed is lower than submersible drilling. 3. Using auger drilling, the drilling process does not require air compressors or mud pumps. However, it can only drill into soil, clay and sand. Second, in terms of drilling technology, we have 2 drilling methods. 1. Direct circulation drilling, where drilling fluid (air or mud) is passed through the drillpipe and cuttings are removed Through the space between the outside of the drill pipe and the hole wall. For reverse circulation drilling, double-walled drill pipe is required. Drilling fluid passes through the space between the inner wall of the outer tube and the outer wall of the inner tube. It is the most effective drilling method for cobblestone and sandy and earthy geological formations.

How to choose a water well drilling rig?

April 26 , 2023

How to choose a water well drilling rig? 1. Drilling efficiency Drilling efficiency depends on formation, operator skill/experience, type of drilling machine and drilling method. 2. Price The price of the machine is a key factor in choosing a drilling machine and is an investment. The price of the machine increases with the diameter and depth of the drilled hole. 3. Operating costs Operating costs can significantly affect the profitability of a drilling business. Net profit is the money drillers receive from well users for drilling a well minus operating costs. 4. Availability of spare parts The availability of spare parts needs to be considered when buying a rig. It is part of operating costs. If spare parts are not readily available, it means you have to pay more to get them, and it takes longer. All of this will inevitably affect the profitability of the land business.

Water Well Drilling Recommendations

April 15 , 2023

While drilling a water well, my drill bit hit something hard and nothing seemed to get through it. Do you have any suggestions? Your drill bit is probably hitting rock, and while you can drill a well in rock, it will definitely slow down the process. Drilling through a large rock can slow the drilling down to half an inch per hour! However, the real problem is not the big rocks, but the small watermelon-sized rocks. On rocks this big, the drill bit has nothing to bite into, so it rolls off. While it’s not impossible to get around rock when drilling a water well, it can be so time-consuming that it may be impractical to drill a well in a particular location. You can always try drilling a well in another location on your property, but there is no guarantee that the rock formation you hit won’t extend under the entire property.
