Rotary Drilling Rig Maintenance & Common Fault Repair

YG Wheeled Rotary Drilling Rig

Daily maintenance of rotary drilling rig

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 rotary drilling rig. YG Drill Equipment Maintenance Department 24-hour consultation hotline: +8613838565351

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.

Cooling system needs maintenance

Check the thermostat and heat preservation device, dispose of the cold diesel engine, 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 about drill equipment, just leave your message, our professional manager will reply 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 run off, and whether the pedaling force of the brake pedal is normal. Whether the brake does not return to position, make adjustments if necessary.

Electrical equipment needs maintenance

Battery; starter and generator; preheating device. Inaddition, if you have any other questions about drill rig 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 peel off is severely, you should do a spray anticorrosion treatment inspection to keep the chassis working normally.

    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.

    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.
