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 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.

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.

    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. 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.

    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, 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.

    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.

    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.
