Down-the-hole drilling rigs can drill holes in rocks of medium hard or above (f≥8). Like the rock drill, it has the process of impacting, rotating, discharging and advancing the rock drilling hole. The difference is the impact mechanism of the down-the-hole drilling rig. The extension and continuous advancement. The down-the-hole drill is named after the impactor dives into the hole, and has the following advantages in use: There is no energy transmission loss, the impactor directly acts on the drill bit, no drill pipe is required to transmit impact energy, and the drilling speed is not affected by the depth of the hole. The hole is stra...

How to choose hydraulic drilling rig bits for different formations? For different types of water well drilling rig equipment, it is necessary to match different drill bits in production. When choosing a drill, you should pay attention to the following aspects: When producing in soft rock with good drillability, the drilling speed is faster, and a large amount of slag discharge and high-quality slag discharge must be selected, and the shape of the four wings is preferably selected. When producing in hard rock, due to the high strength of the rock, each column tooth and drill bit need to bear a large amount of load. Therefore, it is necess...

(1) Maintenance of blasting hole drilling rigs: ① Wipe clean the outer surface of the drilling rig, and pay attention to the clean and good lubrication of the slideway, vertical shaft and other surfaces of the drilling rig. ②Check whether all exposed bolts, nuts, safety pins, etc. are firm and reliable. ③Fill lubricating oil or grease according to the lubrication requirements, see Figure 2 and Table 1. ④Check the oil level position of the gearbox, transfer case and hydraulic system oil tank. ⑤Check the oil leakage in various places and deal with it according to the situation. ⑥ Eliminate other failures that occurred in the class. (2) Week...

DTH DRILL (down-the-hole drill) is a device used to drill holes in rocks (fill the holes with explosives) before engineering blasting A . According to different diameters, down-the-hole drilling rigs can be divided into light-duty down-the-hole drilling rigs (aperture diameter 80~100mm), medium-duty down-the-hole drilling rigs (aperture diameter 130~180mm), and heavy-duty DTH drilling rigs (aperture diameter 180~250mm) The drilling tool is composed of a drill rod, a button bit and an impactor. When drilling, use two drill rod extensions to drill the hole. The rotary air supply mechanism is composed of a rotary motor, a rotary reducer, and ...

The water well drilling rigs are mainly suitable for the construction of water well drilling rigs and geothermal hole construct...

Percussion drilling is an ancient drilling method in the development of well sinking. The percussion water well drilling rig has a simple structure and generally does not have a circulating well washing system. The cuttings removal and the drilling rig cannot be carried out at the same time, so the power is low and the drilling depth is generally longer. Shallow, mostly suitable for construction in pebble gravel or weathered rock formations. There are two commonly used drill bits for percussion water well drilling rigs: one is an I-shaped drill bit, which is suitable for various alluvial formations, especially in the pebble layer and grav...
