Submersible drilling rig maintenance introduction submersible drilling rig maintenance which, diesel engine bearing the brunt of it is the source of the hydraulic system, which directly affects Drill climbing ability, promote (boost) power, torque and rotary drilling efficiency, timeliness maintenance and repair are submersible drilling rig to play the best efficiency of the premise. 1, diesel new or overhauled before use must be run-in rotary drilling rig, in order to improve the reliability and economic life of the diesel engine. Running at less than 70% of rated speed, and 50% of the rated load of 50 hours. 2 ,, should be shut down after the break-wheeled hot oil rig released within the oil pan, oil pan and clean diesel oil network of small rigs, oil and filter change, after run-in period should be replaced once after every 250 hours oil and filter. 3, class clean up the air filter to prevent the diesel engine cylinder. Brief well drilling rig working methods in recent years, as China's economy continues to improve at the same level, water scarcity is becoming a serious problem, most regions have started drilling, so that kind of drilling machinery and equipment then, of course, well drilling rig, which is characterized by advanced structure, the auxiliary convenient, use a short time. Well drilling rig working process is inseparable from the use of the pump, use pump trans loop. Under atmospheric pressure, the circulating fluid from the settling tank through the return ditch along the annular gap flow borehole bottom, perform cycle of work, the formation of reverse circulation drilling. Shandong-Industry Machinery Co., Ltd. is professional development, production of key enterprises of various types of mining equipment, all kinds of DTH production rig, water well drilling rig, it is widely used in mining, utilities and other projects.
