Introduction For Down-The-Hole Drilling Method

图片
A down-the-hole drill, usually called  DTH Drilling Rig , is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer. Considering that the DTH method was initially designed to drill large-diameter holes in surface-drilling software, its title originated in the fact that the percussion mechanism adopted down the bit to the gap. Programs were afterwards discovered for the DTH process underground, in which the management of drilling is usually upwards rather than downwards. DTH didn't need hefty down thrusts or large rotational levels and as such a mild, cheap machine may be utilized to execute the drilling procedure - the system might also be operated by a single individual, whereas other systems demanded two operatives. The advantages that  DTH Well Drilling Rigs  attracted to the sector were so tremendous - for...

Rig operation 20 notes

图片
The following matters should be noted in the operation of the rig: (1) The  water well drilling rig  can be started only after the power machine is running normally. The clutch should be smooth and must not be impacted. It must be light, even and smooth. (2) When shifting the gearbox or the transfer case handle, the clutch must be disengaged first, and the drive shift must be strictly prohibited. After the gear speed is slowed down, the gear can be shifted to avoid damage to the gear. (3) The gear shifting of each shifting gear should be completely covered to prevent the automatic sliding gear from damaging the gear. (4) Check the running parts during operation. For example, the temperature of bearings and gear boxes should not exceed 60 °C. If overheating, stop the machine. (5) If the clutch is found to be hot or slippery, stop the inspection and adjust the clearance of the clutch friction plate. The gap adjustment should be appropriate. (6) Before starting the...

Anti-drilling rig construction

图片
The well drilling boring method was first developed in North America in 1950. In the mid-1960s, the well drilling boring method was popular in Europe, especially in Germany. At that time, the  water well drill rig drilled a diameter of 1.2m and a depth of 150. ~200m; and by the early 1970s, the diameter of the borehole can reach 2.0-2.4m, and the drilling depth can reach 250-500m. Nowadays, many manufacturers in the world have produced anti-well drilling rigs, typically American Robbins. The company can provide 28 types of products, the diameter of the hole is 1.2 ~ 6.0m, the drilling depth can reach 900m, the HG100, 160, 210, 250, 330SP series produced by the German company Welt, the diameter of the hole is from 1.4 to 6.0 m, drilling depth up to 1000m. China has developed anti-well drilling rigs since the 1970s and has applied it in medium carbon and metallurgical systems. The products are mostly concentrated on small-diameter reaming boring machines. In 1992, the hydropower...
