Failures and maintenance of well drilling rig in the face of us know well drilling rig is a lightweight, efficient, multi-purpose tire type full hydraulic drilling rigs for drilling in urban architecture GSHP hole. However, due to a long time in a relatively harsh environment, often failed unexpectedly, in order to avoid faults, routine maintenance is necessary, there often for routine maintenance Symptoms and solutions, small series to sum up a bit : 1. Failure: especially under working conditions, Shandong pressure submersible drilling rig, the drill bit prone to tail broken, the shards into the cylinder stuck hammer, rock dust vent is blocked, down When more water drilling the hole, the exhaust resistance is not easy to start a big impact failure. 2. Treatment: approach to failure is found impactor does not ring, the first period of the impactor upgrade reduce exhaust resistance, the pressure submersible drilling rig, blowing part of the water, and then slowly into the hole at the end, if this method When not working, then the impact is made outside hole to remove for cleaning or replacement parts. Except in the case of complex strata make normal drilling machine sticking outside. Use current situation analysis of rotary drilling rig is currently the world's rig technology is developing rapidly, and this change in trend, sales of air pressure DTH drilling rig, many new technologies, new methods emerging, meanwhile, have more updates for rig requirements promote the development of the rig manufacturing. Recently our country for the construction of roads, bridges, etc., conservation frequently, then rotary drilling rig to be put to use more widely. Only the year 2010, Rotary Drilling Rig sales as high as 1,700. Rotary drilling rig output value in the whole pile driving machinery industry has more than 70%, China has become the world's largest rotary drilling rig market and production base. Then the large rotary drilling rig applications are more and more Shanghai in air pressure DTH drilling rig, large rotary drilling rig has become a development direction of rotary drilling rig, the current large rotary drilling rig on the domestic market to Bauer's BG50 series mostly to larger tonnage TR500C 2010 rotary drilling rig successful downline. On the current situation and the use of science and technology development, the large rotary drilling rig rotary drill will be the new trend in the industry even rig industry. Producers can be adjusted according to the development trend of related products, to meet the challenges of the market. The air pressure down hole drill Which is good, Dragon industry machinery (online consultation), the air pressure DTH drilling rig by Dragon Machinery Co., Ltd. Shandong. Machinery Co., Ltd. Shandong Long (www.longyejixie.com) is Tai'an, engineering machinery parts leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lung industry machinery leadership with the staff warmly welcome all inquiries negotiations to create the dragon industry machinery better future.
