Common malfunctions of rotary drilling rig

Leakage of hydraulic system

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 and rubber ring 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 startability, 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.

YG150 DTH Drilling Rig Machine

Rotary drilling rig machine

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.

This type of borehole drilling rig machine is used on the 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.

YG Wheeled Rotary Drilling Rig

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.

How to Choose The Right Borehole Drilling Machine?

2023-02-202021-07-30 by admin

Borehole Drilling Machine

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, drill holes in a mine, and take 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.

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.

When do you need to drill the borehole?

Drilling is required in many jobs, such as:

Drilling: used to obtain groundwater or oil.
Geothermal drilling: obtain and extract geothermal energy.
Pile-driving borehole drilling machine supporting buildings on unstable ground: up to 2000 mm in diameter and 70 meters in depth.
Micropile drilling rigs: especially for drilling holes for reinforcement of existing structures: between 150 and 200 mm in diameter and within 30 meters in depth.
Blasthole drilling rig in the quarry.
The continuous auger uses drill cuttings driven by the auger to maintain the borehole wall.
Drilling is usually done vertically, but it can also be horizontal or directional, for example for anchoring.

Rotary Piling Machine

Which type of borehole drilling machine should you choose?

There are two main types of a borehole drilling machine: automatic crawler type and truck-mounted or trailer type.

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.

Integrated DTH Drilling Equipment For Sale

Percussion drilling equipment for sale

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. And 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.

Punch grab cone

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, and 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.

Wire rope impact drill machine for sale

It is composed of a mast, a lifting pulley, a steel wire rope, an impact mechanism, a drilling tool, and a motor mounted on the top. During operation, the motor drives the impact mechanism through the transmission device and drives the steel wire rope to make the drill reciprocate up and down. When moving downwards, the weight of the drill bit itself cuts into and breaks the rock formation. And the upward movement is pulled by a wire rope. The stroke of the drill bit is 0.5 to 1 meter, and the impact frequency is 30 to 60 times per minute. The cuttings are cleared out of the ground by the sand pump, and drilling and cuttings are removed at the same time.

Rotary drilling rig

The rotary drilling rig relies on the rotary motion of the drilling tool to break the rock formation to form holes. As a leading drilling equipment supplier in China, there are mainly the following 5 types of drilling equipment for sale.

Pot cone drilling equipment for sale

Use a pot cone drill to rotate and cut the soil layer. The big pot cone and the small pot cone are called according to the size of the drilling tool, which can be driven by manpower or power. The cut soil debris falls into the pot and is lifted to the ground to be discharged. The pot cone has a simple structure and low efficiency. And is suitable for general soil or sand and gravel soil. The drilling depth of the small pot cone is 80-100 meters, and the large pot cone is 30-40 meters.

Rotary drilling rig with circulating mud pump

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 mudflows 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 to 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, sand. And pebbles is smaller than the inner diameter of the drill pipe. The drilling depth is generally within 150 meters.

Compound drilling equipment for sale

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. If you need to buy any type of drilling machine, please feel free to contact the YG drill equipment manufacturer.
