(8) hydraulic oil overheating, low oil viscosity: Stop the Machine and check the hydraulic oil cooling system and hydraulic oil
(9) deterioration of hydraulic oil: replace hydraulic oil;
(10) relief valve failure on the two-speed valve: Clean the valve core or replace it
IV. Key points of drilling operation
1. Start the diesel engine at idle speed or low speed (the rotating speed is no more than 1000r/min), and run it at low speed for 10-30 minutes; If it is in winter, it must run at no load and low speed until the hydraulic oil temperature is above 10℃ before loading and construction.
2. Oblique drilling is very important. Do not make the drilling tool take a sharp bend. There should be more measuring points accordingly. During fixed-point measurement, the driller controls power head to rotate and monitors through synchronous display, making the return angle indication stop at 12 o'clock, measuring the depth of the drill vertex (dip angle), and determining that the next step is Rotary drilling, it is still inclined jacking (according to the depth requirement). If it deviates from the design track, it should be corrected in time. When the instruction stops at 12 o'clock, the drill bit inclines upward, and so on.
3. When pulling a drill pipe back, remove the upper and lower drill pipe buckles. Use the front and rear clamps to clamp the upper and lower drill pipe joints respectively, operate the shackle cylinder to loosen the lower clasp of the drill pipe, loosen the rear clamp, reset the shackle cylinder, and the power head reverse shackle is completed, use the rear clamp to clamp the lower joint, power head reverse screw and unload clasp, and then remove the drill pipe.
5. Key points of preparation before starting the rig
(1) Construction Site Detection: use detection instruments to find out the direction, depth and nature of the original underground pipe network, and make marks; Then use municipal archives, manual site survey and other methods to verify.
(2) Check that the oil level of the hydraulic oil tank should be no less than 1/2 of the oil standard; Fill in sufficient lubricating oil or grease according to the requirements of the lubricating parts of the rig.
(3) do a good job in the maintenance of diesel engine, change the three filters and engine oil regularly, and add antifreeze to the water radiator of diesel engine, and change it regularly. Before starting up, check whether the diesel oil is full, whether the antifreeze is sufficient, whether the oil level of the engine oil is normal, and whether the electrolyte of the battery is sufficient. Confirm that the throttle of diesel engine is in idle position..
(4) Check whether the handles of each valve and all electronic control switches of the hydraulic system are in the middle position and whether the handles of the mud pump are in the neutral position.
(5) confirm that the control direction system operates normally, the battery power of the instrument and probe is sufficient, and the positioning and orientation information (depth, vertex angle and tool facing angle) is accurate.
6: precautions for rig operation
1. Connect guiding drill bit of the installed probe rod with the drill pipe and power head, and confirm that the drill bit water faucet and the drilling rig waterway are smooth and free of leakage before drilling.
2. Align the upper and lower joints of the drill pipe, slowly turn the upper buckle while slowly feeding the power head, and do not tighten too tightly. Wipe the screw thread clean before the button, and apply the screw thread oil.
3. The drilling speed should not be too fast, and the drilling speed should be reasonably selected according to formation conditions.
4. Alkaline batteries should be used for the probe. After the battery is used once, it can never be used again.
5. When making inclined jacking, it is better to control the jacking volume at about 1m each time, and the curve should be slow.
6. When the engine oil pressure of diesel engine is abnormal, stop the machine for inspection (see its operating instructions).
7. When changing the displacement of mud pump, do not shift with speed.
8. Confirm that the operating handle of the rig returns to the neutral position and the diesel engine is idle before shutdown.
7: Power head failure and troubleshooting methods
(1) large leakage in hydraulic motor: maintenance or replacement;
(2) the motor is damaged by large impact load: replace the motor;
(3) low oil pressure: fine-tuning height is relief valve, and lock after adjustment. (It has been adjusted before leaving the factory, and the fine tuning has no effect. Please homing immediately to find other reasons);
(4) relief valve or damage: replace relief valve;
(5) safety valve spring loose or not reset: fine-tuning safety valve;
(6) valve core wear of control valve: Replace control valve
(7) oil pump wear: repair or replace the oil pump;
(8) low rotating speed of diesel engine: increase the throttle of diesel engine;
(9) hydraulic oil overheating, low oil viscosity: Stop the Machine and check the hydraulic oil cooling system and hydraulic oil
(10) deterioration of hydraulic oil: replace hydraulic oil;
(11) failure of relief valve on the double-speed valve: Clean the valve core or replace it
VIII: Diesel engine failure and troubleshooting
(1) line failure: Circuit break, short circuit, poor contact of plug connector, switch failure, etc;
(2) battery shortage: Measure the battery voltage, if it is less than 24v (2 batteries), charge;
(3) hydraulic handle not reset: Diesel engine load thrown on can not start, operating lever reset;
(4) The start button is not in place or the start time is short; Press the button hard and press it for a longer time in cold days;
(5) power switch not closed: close the switch;
(6) gas resistance of oil circuit: loosen the air release screw and press the hand pump to exhaust;
(7) lack of oil: Come on;
(8) no action of shutdown solenoid valve: maintain solenoid valve;
(9) fuse blowing: replace fuse;
(10) the emergency stop button is depressed: the emergency stop button is reset;
(11) cold weather in winter: start after heating circulating water.
IX: hydraulic oil usage and precautions
(1) hydraulic oil is the power Blood of the whole machine. The quality of hydraulic oil directly affects the efficiency and stability of the whole hydraulic system and the life span of each hydraulic component. Therefore, make sure that the hydraulic oil is clean. Considering that the working environment of the drilling rig is relatively harsh, therefore, the cleanliness of the oil should be paid more attention to at all times.
(2) when changing hydraulic oil every time, be sure to clean the oil tank thoroughly and replace all filter elements.
(3) it is recommended to use No. 46 anti-wear hydraulic oil when the temperature is between 10 degrees and 40 degrees; It is better to use No. 32 anti-wear hydraulic oil when the temperature is lower than 10 degrees; It is better to use No. 32 low-setting hydraulic oil when the temperature is lower than minus 10 degrees. To ensure the safety and service life of hydraulic components, please refer to this suggestion.
10: use and maintenance of track chassis
1. All traveling wheel should be filled with lubricating oil at one time. There is no need for refueling and maintenance at ordinary times, but the planetary gear box of walking reducer should be checked once after working for one year. Oil drain hole (outer end face cover) turn to the lowest position and loosen screw plug. If the lubricating oil is seriously polluted, the oil should be changed in time.
2. After completing a project, the track tightness should be checked. Inspection standard: lift the chassis off the ground with the front anchor board and rear legs of the mast, and keep the middle tread of the lower track within the outer edge of supporting wheel. If it is too loose, open the square cover on the side of the walking frame, remove the anti-withdrawal card block and tighten it. After meeting the requirements, install the card block, tighten the anti-loosening bolts, and cover the cover plate. When replacing a new track, adjust the tension screw to the innermost position of guide wheel for easy replacement.
3. During the use of rubber track, it should avoid quick start or turn on sharp protruded stones, rubber covering avoid contact with oil, and wipe it off immediately once there is oil.
