4. Taikuang shearer frequency converter is commissioned to be OEM proced by a company in Shenyang. We have been looking for someone to repair it for many years. The proct has not improved for several years, and the quality is not very good. There are always problems on site. We don't understand why taikuang technology has not improved.

6. 2、 Daily maintenance of the machine
1. The machine should be cleaned (washed) every shift to remove the gangue, cement mortar, wire rope and other foreign matters on the working mechanism, crawler walking parts and other moving parts
2. Lubricating oil should be regularly injected at the pin shaft of the propulsion cylinder, the upper and lower pin shafts of the front and rear support cylinder, and the shaft sleeve of the fixed column
3. The bolts and other fasteners of rotating components and propulsion components in the working parts should be inspected frequently to ensure no looseness, damage or loss. Fasten the loose bolts of track shoes and connecting bolts of structural parts, and replace those that cannot be fastened in time
4. The hydraulic motor, recer in the power rotating device and the propulsion oil cylinder in the propulsion assembly are important parts of drilling operation. Before each shift, they should run without load for 2-5 minutes. If there is any abnormality, they should be eliminated before proction
5. Lubricating oil should be poured on the guide surface every shift, and the sliding clearance should not be too loose, so as to prevent the frame from shaking when drilling, and the pushing resistance will increase when it is too tight
6. Check the hydraulic oil and oil circuit of the hydraulic system
6.1 check the hydraulic oil level
6.2 check the oil return resistance of the oil filter (below 0.2MPa), and flush the filter element according to the situation
6.3 check each pipe joint for oil leakage. Check whether the sealing ring of the hose joint is damaged and whether each pipe fitting joint is loose
6.4 check the hose for extrusion and wear
6.5 record the oil leakage places. If the oil leakage is not serious, analyze the reasons according to the situation. Do not remove or replace the hose and seal in harsh environment. If there is oil leakage or after removal and replacement, check it
III. maintenance and precautions of hydraulic system
1. Safety requirements for maintenance of hydraulic system
when there is pressure in the system, do not loosen the pipe joint, remove the fastening thread and any hydraulic components. After the pump is stopped, the components in the system can be removed after checking that there is no pressure in the system
2. Cleanliness requirements of the maintenance site
when repairing the hydraulic system on site and on the ground, it is necessary to ensure a clean environment and strictly prevent pollutants from entering the hydraulic system. Before loosening each coupling, the surface of the component or connector shall be cleaned, and the opening shall be sealed immediately with the specified plug after disassembly. Gloves shall not be worn and cotton wire shall not be used to scrub the hydraulic component. Oil to the system must pass through the oil filter
3. Oil pipe replacement: replace the damaged oil pipe immediately. The new soft and hard pipes shall meet the requirements of system pressure. Before the installation of the new hose, compressed air shall be used to clean the dirt on the inner wall, and the pipe orifice shall be checked for deburring; The hard metal pipe should be pickled, and the sealing cap should be used immediately after cleaning
4. Refueling: store the hydraulic oil in a clean special sealed container. During ground maintenance, oil should be added to the machine through the oil filter. Before refueling, clean and lint free cloth shall be used to clean the refueling port
5. Replacement of hydraulic components. The model of the replaced components must be correct. When replacing the components, the seals at the joint must be prepared in advance, and the replaced seals must be discarded and must not be reused. The threaded fasteners should be tightened evenly and step by step, and the indivial bolts should not be stressed too much, causing the deformation of components
7. Inspection and replacement of hydraulic oil
7.1 liquid level inspection. If the liquid level is too low, the piston pump and gear pump will be damaged by suction. Therefore, the liquid level indicator on the side of the oil tank should be checked every shift. If the liquid level cannot be seen, the oil should be replenished immediately. Replenish with N46 / N100 anti-wear hydraulic oil
7.2 oil temperature inspection. The maximum allowable working temperature of oil temperature is 65 ℃ ~ 70 ℃. When the temperature is too high, it will accelerate the aging of the oil, shorten the life of the seals and hydraulic parts, increase the leakage, and rece the efficiency of the system. Therefore, attention should be paid to detect the change of oil temperature. If the oil temperature rises suddenly, stop the machine immediately and check the working condition of the oil sample or components
7.3 oil quality inspection. Whether the oil is aged or not can be judged by visual observation
7.3.1 the color becomes dark. There are oxides in the oil. The reason is that the system is overheated, oil change is not complete, or mixed with other oil
7.3.2 emulsification. Pollutants are water or foam. The reason is water or air immersion
7.3.3 water liquid stratification. The pollutant is water. The reason is that the water is immersed in the tank or the cold air is soaked in the humid environment and condensed into water droplets
7.3.4 bubbles. The pollutant is air. The reason is that the liquid level is too low or the oil suction pipe leaks
7.3.5 there are suspended or precipitates. The pollutants are solid particles. The reason is that the oil is aging or the prototype is worn
7.3.6 the oil gives off tar smell. It shows that the aging is serious and caused by fever
7.3.7 oil change: under the condition of good management, the oil in the machine must also be changed once a year
8. Filter inspection. The filter should be checked every shift. The filter should be checked when the oil temperature reaches the normal working temperature of 45 ℃ ~ 55 ℃. If there is still too high oil filtration resistance (the indicator needle is in the red area), the filter element should be replaced. The old filter element cannot be reused
9. Daily maintenance of electrical system
9.1 the machine shall not be parked in the place with water drenching in the roadway
9.2 check the insulation and withstand voltage of the system at least once a month
9.3 check the tightening of bolts on the motor and the tightening of cable inlet and outlet wires
