The management of hydraulic oil is a key part of the maintenance of the full hydraulic core drilling rig. Before each operation, check whether the hydraulic oil level is within the standard range. If the level is too low, add hydraulic oil of the same model—avoid mixing different types of oil, as this can lead to reduced performance. After the operation, observe the color and transparency of the hydraulic oil. If it turns black or turbid, replace it in time to prevent impurities from clogging the hydraulic pipelines.
The inspection of hydraulic pipelines cannot be ignored. Regularly check whether the sealing rings at the pipeline interfaces are aged. If the sealing rings are deformed or damaged, replace them immediately to prevent hydraulic oil leakage. At the same time, check whether the pipeline surface has wear or cracks. For slightly worn pipelines, wrap them with protective tape; if there are cracks, replace the pipelines with new ones to prevent safety accidents caused by pipeline bursts during operation.
The maintenance of hydraulic filters is also crucial. Filters need to be replaced regularly according to the service cycle. When replacing, clean the residual impurities inside the filter housing to avoid old impurities mixing into the new filter and affecting the filtering effect. In addition, after operating in dusty or humid environments, shorten the filter replacement interval to prevent dust and moisture from entering the hydraulic system, which could affect the normal operation of the full hydraulic core drilling rig.
