Hydraulic drilling rig designed for reliability prediction system rigs, drilling equipment can be divided into power head rig, mud pump and drilling tower. Equipment drilling rig is the most important job, the end of the drilling process and from the drilling process. Because the drilling of intent, purpose and drilling is not the same way, so that type of rig diversification. Hydraulic rotary drilling rig spray mainly used in underground construction, set the Jet and drilling in one of the hydraulic multi-function rig, drilling together in the end Jet operations. The rig mainly by the hydraulic system, power head, chuck, lifting organizations, Jet organizations, organizations like walking, constitute a tandem system. Chuck is an important component, the end of Canada, decompression drilling, increased drilling whereabouts, strong pulling and other major processes. Mechanical BU disc generally have normally closed and normally open type two hydraulic drilling rig, we use normal closed, mainly by the chuck housing, piston, disc stretched spring, collar, kava kava blocks and other parts constitute , during severe wear kava, kava use this consumable estimate chuck members of reliability. Development phenomenon submersible drilling rig industry, part of the structure of submersible drilling rig, drill hole works Explanation widely used in drilling and other projects, but many applications are concerned, the use of submersible drilling rig still very strange, because DTH rig has his own unique in its design and construction. For submersible drilling rig in use, it is necessary to understand the structure and working principle submersible drilling rig. Although submersible drilling rig to a large extent and general rig differ, but this is kind of drilling rigs, and submersible drilling rig in general the principle is similar. DTH DTH hammer drilling machine is a hydraulic submersible drilling rig such a composition, the piston within the cylinder, valve seats, check valve and drill accessories mounted on the elongated outer cylinder, the outer cylinder has a mouth fitted with Wrench and the connecting thread of the joint, with the bottom of the card solder sleeve threaded connection. Card solder sleeve main propulsion and for transmitting rotary motion to the drill bit. Card-loop control axial movement of the drill bit, and the check valve when the supply of compressed air when used to harm only rock debris and other debris into the impactor. Submersible drilling rig in the use and maintenance, because the impact of the joints and fittings are right-hand thread, so the drilling operation, should always maintain the right swing impactor. When opening, the impact should be minimal and propulsion, the bit smoothly into the formation. Propulsion and drill weight matching is very important, propeller thrust must drill with weight changes.
