Processing a rotary drilling rig because the mast to adjust the cylinder seals of a serious oil spill drill rig, often affect rig construction, after a group of seals replaced after the commissioning of the mast no problem. In the afternoon to the site ready for drilling operator when it carried out the first look at the mast debugging, but suddenly not the right tone decentralized, operator thought it was the beginning of the mast upper limit position solenoid valve stuck, and checked no, small rig manufacturers, and then check the mobilization of the valve solenoid valve-related, small drills, did not find the problem, and that in the end is what a problem? After much thought to check, the final decision on the two upper and lower hydraulic cylinder locks washable adjustment once installed and then see how the mast debugging. Flat again mast erected around tilt back and forth repeatedly to do everything to normal after several debugging, small rigs offer, let the machine start to pile operator position to begin construction. The reason is, there should be two things: one, is itself one of the hydraulic lock in the absence of replacement seal on a problem, when the mast left no right tone adjustment flexible, small-scale mining rig, so the two hydraulic Lock the pressure was adjusted so that the two pressure remains the same; second, the incumbent oil seals, cylinder tubing that somehow disassembly. The demolition of a mounted pipe to form a vapor lock, sometimes affect the hydraulic pressure vapor lock can not be opened by the upper hydraulic cylinder lock, can not form a hydraulic circuit, certainly not lowered. So by this draw so little experience, speak out and we were discussed. Auger drill head maintenance measures is a rotary drilling rig foundation engineering construction machinery operations fit into the hole. Mainly suitable for construction sand soil, clay soil, silty soil, etc., in piles, multiple continuous wall, foundation reinforcement and other foundation construction has been widely used. Today, small series of rotary drilling ring powerhead maintenance experience to share with you, first of all talk about replacing the auger drill head grease ways, besides inspection and replacement of the power head spline gear oil step, I hope to bring the faithful circle some help. Replace the auger drill head lubricant 1. Remove the power head drive device located below viewing cover. 2. From the holder on the upper frame to remove drain hose, the hose end of the vessel. 3. Use a universal joint having a sleeve extension section to loosen the vent valve, drain the oil into a suitable container. 4. Tighten the bleed valve. The exhaust pipe hanging in the holder, make sure the hose end upwards. 5. Replace the auger drill head oil should Remove the dipstick. 6. Fill quantitative dipstick tube oil. 7. Keep the oil in the oil-foot top and dipstick tags. Small hydraulic rig rig _ _ small dragon industry machinery supplied by Shandong Machinery Co., Ltd. Dragon.
