Rig Rig friction clutch plate friction clutch in a large drilling rig equipment, this part is easy to produce in large-scale drilling rig problems, require producers to produce in serious attention to prevent the problems affecting productivity, unusually Mainly as the main factor is not functioning properly, the cause of such factors is due to friction plate wear or oil to penetrate, so in order to avoid this problem, reduce the production of wear and tear, when unnecessary, you should try not to use nip, nip when the clutch, you must use the cam smooth large-scale engineering drill through dead works, and locking. Loosen the time when large-scale projects rig accessories, cam also be pulled out from this position, and does not involve pressure plate. 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, therefore less efficiency, drilling depth is generally at 250 meters, sometimes up to 500 to 600 meters. Composite Rig additional impact mechanism on the basis of the turntable on the rotary drilling rig to the main rotary drilling, when faced with gravel layer is the impact of dual-well drilling Rig, adaptable to a variety of formations. 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. 2015 large-scale drilling rig | Prius | Weiyuan County large drilling rig provided by Luoyang Prius Drilling Equipment Co., Ltd.
