Engineering drill include: impact drilling rig, engineering composite drill, rotary well drilling rig. Below we Depending on the application range and characteristics of different projects rig, to provide the basis for the selection of drilling rig. Impact Rig by vertical reciprocating motion drill, drill meat is shock situation, broken rock, simple structure, no circulatory system, debris removal can not be performed with the drilling rig colleagues, and therefore lower the effectiveness of large-scale drilling rig manufacturers, drilling depth generally less than 250 meters, sometimes up to 500 to 600 meters. Composite Rig additional large-scale projects on the basis of the impact mechanism turntable rotary drilling rig drilling rig on how much money to the main rotary drilling, when faced with gravel layer is the impact of dual-well drilling rig drilling of various strata adaptability. Another is to combine the role of impact with the rotary drilling well drilling rig. Rotary well drilling rigs, rotary motion of the drill rely broken rock drilling holes. When the job force by the actuator driving wheel, driven by the initiative of rock broken drill bit rotation. Electro-hydraulic proportional control technology applications in engineering in engineering drill rig production, drilling rig how to automate production control, depending on one gate technology, this technology is the electro-hydraulic proportional technology, mechanical engineering technology as a proportion electrophoresis system interfaces, control engineering rig automated production. Drilling rig used in electro-hydraulic proportional control technology after major drilling rig, can be very good to simplify the system of production, complex process control, thereby reducing production costs, improve project quality control process large rig drilling rig image, improve production reliability shorten the drilling rig working cycle time. Electro-hydraulic proportional technology applications engineering drill, is more conducive to automated drilling rig, efficient, intelligent development, but also to improve production efficiency and control performance engineering rig, has an important value, which is electro-hydraulic Proportional technology existence.
