Various types of rotary drilling rig rotary drilling rig purchase conditions Performance range is very large, for the construction of such pile diameter is very suitable. The principle of rotary drilling rig should be able to meet the needs of the user's current main project, taking into account engineering requirements that may occur in the future. Further well drilling cars for sale, rotary drilling rig performance parameters to leave room for development. Rotary drilling rig in accordance with its main operating parameters: can be divided into torque, engine power, hole diameter, depth and drilling rig machine quality for the purchase of three types: (1) Small rotary drilling rig. Small rotary drilling rig applications: various gallery of piling, pile floor section bearing structure, a variety of urban renewal projects of less than 1m municipal pile for pile for other purposes. Small rotary drilling rig Technical parameters: torque 100kN2m, engine power 170kW, hole diameter 0.5-1m, drilling depth of about 40m, 40t quality about the whole rig. (2) mid-sized rotary drilling rig. Medium rotary drilling rig applications: bridge piles of various highways, railways and other transport facilities bridges, large buildings, ports pile load-bearing structure, urban viaduct bridge piles, other applicable piles. Medium rotary drilling rig Technical parameters: torque 180kN2m, engine power 200kW, hole diameter 0.8-1.8m, drilling depth of about 60m, 65t quality about the whole rig. (3) large rotary drilling rig. Large rotary drilling rig applications: all kinds of highway, railway bridges Bridge pile, the special structure of other large buildings bearing foundation piles. First explain the type of impact drill, hammer drill a water well drilling rig belonging Qinghai well drill rig, its main components, including power equipment and drill bits, drill pipe, core pipe, drilling rig and other functions to complete the well pipe, wash Machinery wells and other operations, which works by vertical reciprocating motion drill, impact drill bit to break rock bottom, and they are rope hammer drill, punch caught two types of cone rig; one rope Impact drills , the main mast and the top end of the lifting tackle, wire rope, impact mechanism, drilling (including drill pipe and drill bit), motors and other components, which are generally surfacing drill tungsten steel powder, alloyed welding drill, the main purpose is to improve wear and drilling speed; second punch caught Cone Drill wells, function is to use the weight of the impact of the formation itself, is a simple hammer drill wells drilled car, when the weight of the tool itself downward movement , grab flap open, cut the tip of each petal rock grab on the circumference of a diameter of about one meter, then through the wire rope hoist lifting drilling process debris caught in the grip into the tip in the closed valve body, made after opening the wellhead catch unloading valve wells drilled cuttings Which car |.
