Working Principle Of Rotary Drilling Rig
Rotary Drilling Rigs utilize high levels of torque and rotation, with a drill bit at the end of the drill pipe rapidly rotating and boring through the rock formation. The high frequency and speed of rotations make this form of drilling an effective means of carving through both hard and soft rock formations, alike. This form of drilling uses either air or drilling fluids to clear out the borehole, cool the drill bit, and generally reduce friction on the bit so that it can continue to run optimally.

You need a borehole drilling machine for various purposes. For example, drilling a well to obtain natural resources (water, oil, geothermal energy, etc.) to build a foundation, drilling holes in a mine, and taking samples from the ground.
First, you need to determine the purpose of the borehole drilling machine. And what kind of terrain is the main work on? Depending on the terrain, you can choose different types of drilling rigs. For example, rotary drilling rig, impact drilling rig, down-the-hole drilling rig, top hammer drilling rig (with the high hammer), etc.
Rotary Drilling Rig Machine Lock Rod Drills Machine
In order to make the best choice, it is important to determine whether the borehole drilling machine is used for core business or occasional use. Especially whether you use the latest technology. Or whether a machine that has been used for decades is right for you.
The safety, reliability, and ease of use of drilling rigs are also important factors that need to be considered, and there is a direct connection between them. The use of reliable and easy-to-operate drilling rigs according to the manufacturer’s recommendations can improve user safety.
It is also very important to define the type of movement required by the rig. There are crawler-type automatic drilling rigs and truck-mounted or trailer-mounted drilling rigs, which need to be powered by generators or trucks that carry them.
Once the type of rig required is determined, the required rig size can be calculated based on the diameter and depth of the borehole.
If you need to move at a low speed on uneven areas or very soft ground, you can choose a crawler drill. The stability of the rig depends on the surface area of the track. Therefore, the wider the crawler, the more stable the drilling rig. However, crawlers that are too wide tend to wear out faster and damage the ground when moving, especially when turning. The crawler drilling rig has a travel speed of about 4km/h, so it is more suitable for operations that require little travel.
A truck-mounted or trailer-mounted borehole drilling machine is not autonomous in mobility or energy. These energy sources may come from transport trucks or independent generators. However, this type of drilling rig is much lower in cost than crawler drilling rigs.
Routine maintenance needs to wipe clean the surface of the rotary drilling rig‘s case. And pay attention to the cleaning and lubrication of the rig’s base slide, vertical shaft, and other housings. Check whether all exposed bolts, nuts, safety pins, etc. are connected intact. Add lubricating oil or grease according to the lubrication requirements. Check the oil level of the transmission, transfer case, and hydraulic system oil tank. In addition, check the oil leakage everywhere and deal with it according to the specific situation. Eliminate other faults. Pay attention to maintenance during daily use of the rotary drilling rig. YG Drill Equipment Maintenance Department 24-hour consultation hotline: +86 18337123872
In winter and summer, the seals of the rotary drilling rig are prone to thermal expansion and contraction, which may cause leakage. Especially install O-shaped rubber rings and other seal positions.
Fuel System Maintenance
Replace diesel fuel regularly. Because diesel fuel is prone to deposits after long-term use. As a result, the viscosity of diesel oil increases, and the flow becomes slower. Therefore, it is prone to waxing, atomization, and insufficient combustion. It is easy to cause the diesel engine’s start ability, power, and economy to decline. When maintaining other parts, you also need to thoroughly clean all filters; disassemble the fuel filter; drain the sewage in the oil-water separator; eliminate potential safety hazards that may cause accidents.
Check the thermostat and heat preservation device, dispose of the cold diesel engine, and replace and add antifreeze. If you are looking for the top drilling machine manufacturer, our company is the best choice definitely. Or if you have any problems with drill equipment, just leave your message, and our professional manager will reply to you within 12 hours.
The Brake System Needs Maintenance
When replacing the brake fluid, all the original brake fluid must be discharged first. Inject new brake fluid. Check whether the oil-water separator can drain all the sewage. Check the condition of the brake system. And check whether the brakes are weakened or runoff and whether the pedaling force of the brake pedal is normal. Whether the brake does not return to position, make adjustments if necessary.
Battery; starter and generator; preheating device. In addition, if you have any other questions about the drill rig’s electrical equipment, just leave your message.
Chassis And Other Maintenance Items
Check whether the chassis bolts and nuts are tightened. Check for loose or missing steering system bolts. Apply lubricating oil to the place that needs lubrication, check the leakage of the chassis pipeline, and solve it in time. If the chassis paint peeling off is severe, you should do a spray anti-corrosion treatment inspection to keep the chassis working normally. If you are looking for high quality and cheap rotary drilling rig for sale, please feel free to contact us at any time. YG will be your ideal partner.
This type of drilling rig machine uses a tool to grind the rock to drill a hole under the action of weight and rotation. Mainly used in oil production. The cuttings are brought to the surface under the pressure of the drilling fluid injected into the drill string. The drilling fluid also helps to consolidate the borehole wall, so there is no need to treat the borehole wall during operation.

DTH Drilling (Rotary Percussion Drilling Or Rotary Hammer Drilling)
This drilling method uses a drill and a rotary cutter (drill bit) is used for drilling. And punch the bottom of the hole with a pneumatic hammer. The excavated material rises to the ground under the pressure of compressed air with a hammer. This type of drilling rig is powerful and has a high drilling speed, especially in rocks. For artesian wells (wells in which water naturally rises to the surface under groundwater pressure) or geothermal drilling, air injection at the end of the drill pipe pushes the water up the hole. This allows the operator to immediately determine the water flow encountered.
hard and cracked ground up to 4000 meters deep. When the drill bit is eccentric, a casing propulsion system (where the pipe is installed by gravity) can be used to drill the hole. The system will strengthen the hole as the drilling progresses.

Top Hammer Drilling
The drilling rig machine used for this type of drilling can also be run on the percussion system. But the rig is still located outside the borehole. They are mainly used for small-diameter drilling. For example, it is used for mineral exploration or to install tie rods in rocks. This drilling system is used for shallow drilling. Because the ground structure drilled through may produce significant deviations. This drilling rig can work in any direction.
Spiral Drilling
This is a type of rotary drilling that uses a worm (auger). This type of drilling is mainly used for loose clay or sand. The worm will bring the excavated material directly to the ground. For deep hole drills, the auger needs to be lifted regularly to empty its digging material.

Core Drilling Rig Machine
Core drilling is similar to rotary drilling. But it uses the top to extract a sample inside the tool, called a core.
Percussion Drilling Rig Machine
Percussion drilling refers to the use of tools and drills to break rocks under the action of gravity. This type of drilling can only be used vertically. In order to prevent the borehole from collapsing, it needs to be protected when drilling. Once the drill cuttings interfere with the drilling, replace the drill bit with a flap valve guide tube and reassemble the drill cuttings. The flap valve guide tube is a tube with an inclined flap at the lower part. The inclined flap can fill the pipe with excavated material and then transport it to the ground.

Pipe Jacking Drilling Rig Machine
Jacking pipe drilling is mainly used for the installation of horizontal pipes. The pipe is gradually pushed through the impact. At the end of the drilling operation, the excavated material is removed by water injection or using an auger (endless screw). This technique is especially used to avoid transmitting vibrations to surrounding buildings or to avoid trenching.
The percussion rig relies on the vertical reciprocating movement of the drilling tool to make the drill bit hit the bottom of the well to break the rock formation. The percussion drilling rig has a simple structure without a circulating well-washing system. Furthermore, the removal of cuttings and the drilling rig cannot be carried out at the same time, so the efficiency is low. The drilling depth is generally within 250 meters, sometimes up to 500-600 meters. There are mainly the following 2 types of drilling equipment for sale.
The punching cone uses the weight of the drilling tool itself to hit the formation. At the lower end of the drilling, the tool is several sharp-angled gripping flaps that can be opened and closed. When the drilling tool moves downward under the action of its own weight. The gripping flaps are opened and cut into the rock formation. Then the drilling tool is lifted by the hoist through the wire rope, the cuttings are grabbed into the cone by the gripping flap during the closing process, and the cuttings are lifted out of the wellhead. The drilling depth is usually 40-50 meters, and the deepest is 100-150 meters.

Rotary Drilling Rig With Circulating Mud Pump
As a matter of fact, it is composed of a tower, hoist, turntable, drilling tool, mud pump, faucet, and electric motor. During operation, the power machine drives the turntable through the transmission device. The active drill rod drives the drill bit to rotate and break the rock formation. There are positive and negative circulation methods. When the positive circulation drilling rig is working. The bottom hole cuttings are carried out of the wellhead through the annular channel outside the drill pipe. After the sedimentation tank settles, the mud flows back to the mud tank for recycling. Contact us to get rotary drilling equipment for sale price.
When the reverse circulation drilling rig is working, the mudflows into the bottom of the well from the wellhead after it settles in the sedimentation tank. And the mud that carries the cuttings is sucked out of the well through the drill pipe cavity by the sand pump through the bit nozzle and sinks back into the sedimentation tank. The drilling rig forms a high-rising velocity in the drill pipe. And has a strong ability to discharge cuttings and pebbles. Circulating mud washing rotary drilling rig has a fast drilling speed and is suitable for loose formations where the diameter of the soil, is sand. And pebbles are smaller than the inner diameter of the drill pipe. The drilling depth is generally within 150 meters.
Rotary Drilling Rig With Compressed Air Flushing Well
In fact, on the rotary drilling rig, the air compressor is used to replace the mud pump, and the compressed air is used to replace the mud to wash the well. The reverse circulation method is usually used, also known as gas lift reverse circulation. Therefore， it is suitable for arid areas with large-good depths and water shortages, and permafrost in cold zones.
Hydraulic Power Head Drilling Rig
Furthermore, it is driven by a hydraulic motor through a reducer, and a powerhead that moves up and down along the tower replaces the turntable and faucet on the turntable drill to drive the drill rod and bit to rotate and cut the rock formation. Large-diameter water wells can be drilled.
Frankly, drilling into the rock formation by a combination of vibration and rotary motion. The drilling tool is composed of a drill bit, a vibrator, a vibration absorber, and a guide tube. The vibrating force generated by the vibrator makes the whole drilling tool make a cone pendulum movement to break the rock formation. The compressed air reverse circulation method is used to wash the well. So that the cuttings are discharged out of the well through the pipe and the inner cavity of the drill pipe. The drilling depth can reach 150 meters.
There are 2 types of compound drilling equipment for sale. One is a water well drilling rig that combines impact and rotation, such as a pneumatic down-the-hole hammer drill. The down-the-hole hammer drill is composed of a cylinder liner and a piston.
The high-pressure air provided by the industrial air compressor drives the piston to reciprocate up and down, impacting the drill bit to enhance the drill bit’s ability to drill into the rock formation. At the same time, the drilling tool rotates at a relatively low speed of 35-60 rpm. The air discharged from the upper and lower cavities of the piston enters the drill bit and carries the bottom cuttings out of the wellhead. The pneumatic down-the-hole hammer drill can be used for drilling deep wells in hard rock formations, with high drilling speed and straight boreholes.
The other is to add a percussion mechanism on the basis of the rotary drilling rig. Which is mainly used for rotary drilling. When encountering a pebble layer, the two-water well drilling rig that uses percussion drilling is highly adaptable to various formations.
