What is the drill? Drill, is a complex machine, caterpillar DTH drill consists of a machine, units and institutions. Rig is in the exploration and mineral resources (including solid ore mine, liquid, gas, ore, etc.) development, drive the drill into the ground drilling, physical geological data for mechanical equipment. Also known as the boring machine. Main function is to drive drilling tools and broken rock at the bottom of the bore, down or in hole drilling tool is put forward. Can be used for drilling and coring, ore core and cuttings, gaseous, liquid, etc., to the underground geological and mineral resources, and so on and so forth. Gansu DTH drilling rig equipment usually has the following seven: 1. 2. Regular land RIGS desert rig 4 consecutive tubing unit 5. Deviated well drill 6. Offshore drilling platform 7. Drilling ship and other seven types.
Positive cycle of drilling, downhole cuttings was out of the mouth of the well through the perimeter of the drill pipe channels, after precipitation tank, mud flow back into the mud pit for cycle use. Reverse circulation drilling machine is working, mud from the mouth of the well to flow into the bottom hole after settling basin precipitation, DTH drill cuttings to carry mud is in gansu province by sand pump through a bit nozzle through the suction pipe inner cavity up well, back to the sink to the tank. Rising drill in the drill pipe to form a high velocity, strong ability to discharge of cuttings and pebble, drilling speed, applicable to the soil, sand and pebble diameter less than loose strata of drill pipe inside diameter. The drilling depth is in commonly 150 meters. Pneumatic rotating disc drill wash well. On the wheel rotary drilling rig with air compressor instead of mud pump, the use of compressed air instead of mud to wash well. Usually adopts the reverse circulation method of hydraulic power head drill. Caterpillar DTH drill driven by hydraulic motor through the gear reducer, and to move up and down the tower of power head instead of rotating disc on the rig rotary table and faucet, drive drill pipe and drill rotating cutting rock. To drill large diameter water well.
What about water well drilling rig track maintenance and maintenance? Of water well drilling rig track cleaning: cleaning the crawler DTH drill, should be cleaning the sludge on the lower body to walk at the same time, after the operation, homework personnel in cleaning the DTH drill in gansu province bridge at the same time also to cleaning of the sludge on the lower body to walk, if the lower body to walk on sludge. Are unable to check the relevant components. Therefore, please be sure to remove these sludge, and the lower body to walk for inspection and maintenance. All in all, here small make up remind rotating drill crawler tractor driver to pay more attention to the situation, such as bolts loose? The sprocket and roller can't turn? Sprocket, roller and the drive wheels oil? Such as ignoring the abnormal state, will cause serious accidents. If due to the bolt fracture and make the relevant parts damaged and sprocket wheel or roller grinding partial, will greatly increase the maintenance cost.
