Product Description:

OTR400D:

 

A drilling rig is a machine which creates holes in the earth sub-surface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and are called augers. Drilling rigs can sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earth's crust.

 

Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth's crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.

Multipurpose design for cylinder crowed system. Sensor and control center realize real-time measurement of the inclination angle, auto adjustment of mast verticality and inching adjustment.
6.Crowd system by means of long stroke hydraulic cylinder or crowd winch separately, are option for your exact request.
7.Rotary head with variable displacement motors and one high spin off speed. And rotary is extremely reliable, it has been disgned in order to gurantee a very compact, efficient and powerful rotary. The transmission group of rotary is made up of a hydraulic motor and new power shift purposely studied and designed to obtain maximum perfomance. During the drilling phase, the rotary has the entire power of the diesel at its complete disposal. Adapter of rotary is essential to absorb the considerable shock connected to the high speed of the main winch.
8.Telescopic kelly bar with guide made by high quality specially for high boring strength and torque force. Available with friction or inter-locking type.
9. All the main hydraulic components(pumps, valve, motor, connector) are from well-known international brands such as Bosch-Rexroth, brevini, which ensure the stability, reliability, high-efficiency and energy-saving of the entire system
10.Electronic controlling system is an innovative system, developed by Osaint, which controls and monitors the operation of the machines. For ease of operation, the system is controlled by a touch screen located in the cab. The system function is to enable the machines to perform different functions more efficiently. A dedicated power module electronic control and CAN-Bus system ensures the main pumps and Disel engine to work at their most effective and productive stages.

Q:XCMG XR360 rotary drilling rig generally how much?
The reasonable price is based on your own, do you do it yourself? Where are you from and where is the project?
Q:Are our common rotary drilling rigs the same as those for well drilling machines?
A dozen meters of drilling hole, is to drink water, drink water to break the stone, no stone rig also never mind, in Loess
Q:What's the difference between a long auger and a rotary drill?
1., first of all, the cost of machinery, screw digging more expensive than the long spiral.2. construction methods are not the same.3. long spiral diameter generally below 1 meters, 400mm, 500mm, 600mm more, common drilling depth is generally within 15 meters, -32 meters. More than 1 meters in diameter, you have to use rotary digging or other.4. long spiral applies to high-speed rail foundation construction, civil construction, rotary excavation in relatively large diameter foundation construction, such as bridge foundation construction is more common.
Q:What are the hidden dangers during the construction stage of rotary drilling rig?
Hole air quality, hole wall quality, water gushing, quicksand and other geological conditions, orifice protection, safety protection inside and outside the personnel hole, mechanical equipment operation conditions, probably on these, one, a good grasp on the fine.
Q:Does the rotary drilling rig require a national issued operating permit?
Rotary drilling rig as a complex special equipment, the state mandatory to apply for operating permits, undocumented operations will face fines, and the occurrence of an insurance accident, the insurance company will not pay compensation!
Q:What are the components of rotary drilling rig Jixietaiban? How to calculate?

The current domestic rotary drilling rig manufacturers and models are more well-known manufacturers are mainly ZOOMLION, 31 heavy machine, Xugong, CSR, Futian, Shanghai Kim, Tianjin sunward, Bauer, Wujiang geotechnical, Yutong, mainstream rock into the rotary drilling rig has 31 main SR280R into the rock rotary drilling rig, Zoomlion ZR280 360, Xugong, Bauer BG25 into the rock can be, but the price is not high, 31 C8 series rotary recently to participate in the 2014 Shanghai BMW exhibition drill SR285RC8/SR385RC8, is said to have ability to exceed the traditional rock entering into the rock type rotary drilling rig.
Q:Wylong machinery rotary drilling rig in the use of the external power? How many volts does it take to drive?
Rotary digging is power driven hydraulic, you ask about the spiral bar
Q:How should we deal with the abnormal encountered during the construction of rotary drilling and drilling?
When the hole is not serious, the drilling can be continued by adopting the measures of increasing the specific gravity of the mud, heightening the water head and burying the deep protecting cylinder. When the hole is serious, the backfill will be drilled again.When drilling and bending holes occur in the drilling hole, the drill bit of the rotary drill can be raised to the inclined position for repeated hole sweeping until the drilling is upright. In the event of serious bending hole, plum blossom hole, probe stone, the small stone or gravel and clay mixture backfill to deflection, to be heavy filler after re drilling deviation.When drilling, it is not strong lifting. The cause and location of the bit shall be ascertained, and large ropes shall be moved, small bit impact shall be taken, and other measures taken to make the drill loose and brought up.
