Rig routine maintenance 1, wipe clean the surface drilling rig, rig attention lubricating and cleaning and other base runner and vertical surfaces. 2. Check all rig exposed bolts, nuts, safety pins and other solid and reliable. 3, injection of oil or grease shall be in strict accordance with the lubrication requirements, and must use reliable quality lubricants, deep drilling rig models, disabled poor quality lubricating oil, lubricating oil mixed with caution, try not to mix different grades of lubricating oil . 4. Carefully inspect the rig transmission, transfer case and fuel tank hydraulic system. 5. Check the rig vulnerability and seriously deal with the various components depending on the circumstances. Check the vulnerability causes, such as seals badly worn seals should be replaced. Abnormal leakage is necessary to consider downtime. 6, eliminate other faults occur within the same day of duty. Well drilling rig hydraulic pump failure Check the hydraulic pump is the core structure of the drilling rig, the hydraulic system of the power source, the equivalent of machinery and equipment "heart", of course in the long-term use or improper use, the Shanghai Deep Drilling Rig , will result in a failure to produce hydraulic pumps, hydraulic pump failure when we need timely resolution. The reason the first thing is to check the fault generated: 1. Check the boom cylinder leakage situation. The easiest way is to raise the boom to see if there is a significant decline in freedom. If the fuel tank drop significantly the disassembly inspection, such as worn seals should be replaced. 2. Check the control valve. First clean the safety valve, check valve body wear, such as wear and tear should be replaced. If after the safety valve remains unchanged, deep drilling rig, and then check the control valve spool wear, the gap is generally limits the use of 0.06mm, severe wear and tear should be replaced. 3. Measure the pressure of the hydraulic pump. If the pressure is low, deep drilling rig mass, adjusted, plus the pressure is still not tune up, then pump heavy wear.
