How often does the rotary drilling rig do maintenance?
In drilling rig construction, it is necessary to do the routine maintenance work for the drilling rig at any time:1, each work before the drill rod feeder (wire rope connector), add butter;Note: make sure that the grease nozzle at the other end is unscrewed when greasing the end of the boot. This will help to squeeze the butter out. On the contrary, the oil seal in the lifting device may be squeezed out, and the dirty water containing fine sand can be easily entered, and the bearings can be worn down and the sensitivity of the lifting device can be lowered.Note: the new lifting device has been improved. Please contact the SANY customer service department for maintenance.2, each job before the drill rod to follow the guide frame (drill pipe support), bearing, add butter;3 、 always check whether the wire rope is in good condition;4 、 check the damage of tubing and sealing ring regularly, prepare spare parts to meet the urgent need;5, always pay attention to whether the circuit relay aging, early preparation of spare parts;6, check the drill rod lift (wire rope connector) bearing rotation is flexible, if damaged, should be replaced immediately;7. Check the bolts and pins regularly for wear and tear. If damaged, replace them immediately.
1) each movement shall pay the grease according to the lubrication sign, and the main part of Carter shall be carried out according to Carter's lubrication requirements. For example: turning on the car, slewing bearings and other relatively large parts of the rotation, it must be in the entire rotary surface plus enough butter, each rotation of a certain angle to fill once;2) lubricate the main and auxiliary steel wire rope and butter each share;3) apply grease to the three sides of the mast rail;
Maintenance of rotary drilling rig before and after constructionFirst, before drilling rig construction, it is necessary to do the following maintenance work on the rig:1, check the fuel tank is sufficient oil, oil is normal;2, check the gear reducer oil is sufficient, the oil quality is normal;3, check whether there is oil leakage fault;4. Check whether the main and auxiliary steel wire rope is broken or not and whether the connection is safe and reliable, and whether the rope driver is enough or not;5. Check whether the boot is flexible and whether the internal butter is contaminated;6, check the parts of steel structure has no cracks, corrosion, welding and other damage and repair;7. Fastening the loosened hose and bolt;8, according to "rotary drilling rig and matching drill pipe simple use and maintenance manual" requirements check and repair drill rod;9, lubrication
