Maintenance of linear boring machines mainly includes the following aspects:
Appearance and connection inspection:
Check leakage: Before starting the machine every day, carefully check whether there is oil leakage in the pipelines, joints, hydraulic cylinders and other parts of the hydraulic system. Small leaks may gradually develop into serious problems and affect system performance. Once a leak is found, it should be marked and repaired in time, and loose joints should be tightened or damaged seals should be replaced.
Check the pipeline condition: Check whether the hydraulic pipeline has wear, scratches, deformation, etc., especially at the connection between the pipeline and the equipment and the parts where the pipeline passes through large vibrations. For damaged pipelines, they should be replaced in time to prevent ruptures and cause safety accidents.
Confirm component connection: Check whether the connection of hydraulic pumps, valves, filters and other components is firm, loose or no abnormal noise. Ensure that the electrical connection is normal, without looseness, short circuit and other problems, to avoid system failures due to poor connection.
Oil management:
Check the oil level: Check the hydraulic oil level through the level gauge on the oil tank to ensure that the level is within the normal range. If the level is too low, the oil pump may be sucked empty and damaged; if the level is too high, the oil may overflow. If the level is insufficient, add hydraulic oil that meets the requirements in time.
Observe the oil quality: Regularly observe the color, transparency and cleanliness of the hydraulic oil. Normal hydraulic oil should be clear and transparent. If the oil becomes turbid, black or has a peculiar smell, it may mean that the oil has been contaminated or oxidized. It is necessary to conduct oil quality testing in time and decide whether to replace the oil based on the test results.
Control the oil temperature: Pay attention to the working temperature of the hydraulic oil, which should generally be controlled between 30℃-60℃. If the oil temperature is too high, it will accelerate the oxidation and deterioration of the oil, reduce the viscosity and lubrication performance of the oil, and affect the normal operation of the system; if the oil temperature is too low, the viscosity of the oil will increase, and the pressure loss and energy consumption of the system will increase. Pressure and flow monitoring:
Pressure check: Use a pressure gauge to regularly check the working pressure of the hydraulic system to ensure that the pressure is stable and meets the specified value of the equipment. If the pressure fluctuates or rises or falls abnormally, it may be a fault of the pressure control valve such as the overflow valve or the pressure reducing valve, which needs to be adjusted or repaired in time.
Flow observation: Although flow monitoring is relatively complicated, it is possible to indirectly judge whether the flow is normal by observing the movement speed and working status of the actuator (such as the hydraulic cylinder, hydraulic motor). If the actuator moves slowly or unstably, it may be insufficient flow or a problem with the flow control valve, which requires further inspection.
Filter maintenance:
Check the filter status: Regularly check the inlet and outlet pressure difference of the filter. If the pressure difference is too large, it means that the filter is clogged and needs to be cleaned or replaced in time. At the same time, observe whether the filter housing is damaged or deformed to ensure its normal operation.
Replace the filter element on time: Replace the filter element regularly according to the requirements of the equipment instruction manual. Even if the filter pressure difference does not meet the replacement standard, it should be replaced when the specified time is reached.
