Description

Alternating lubricating oil filter tube group based on cantilever beam sliding system Technical Field The utility model relates to the technical field of cantilever beam lubrication systems, in particular to an alternating lubricating oil filter tube group based on a cantilever beam sliding system. Background The lubricating system of the cantilever beam sliding system of the self-elevating drilling platform is used as a core subsystem for guaranteeing the efficient operation of equipment, and a circulating lubricating oil mode is generally adopted to cope with the challenges of high salt fog, high humidity and frequent mechanical abrasion of the marine environment. In the system, lubricating oil is required to be filtered in multiple stages to remove metal scraps (such as iron and copper particles) and pollutants (such as sediment and colloid sediment), so that the wear rate of key parts such as a sliding rail, a hydraulic cylinder, a gear box and the like is reduced, and the overall service life of equipment is prolonged. In the prior art, the lubricating oil filtration generally adopts a grading treatment process, namely a rough filtration stage, namely a metal filter screen is adopted to intercept larger particles and construction residual impurities, and a fine filtration stage, namely a high polymer material filter core is configured to carry out deep purification, so that the cleanliness of the oil can meet the requirements of more than 18/16/13 grade in the ISO 4406 standard. However, in practical application, the metal filter screen in the rough filtration step is easy to generate rapid blocking phenomenon due to long-term exposure to high pollution environment (such as drilling mud infiltration and metal abrasion and debris accumulation), and is characterized in that flow rate is attenuated, the pressure difference of an oil way is increased due to the blocking of the filter screen, the flow rate of a system is reduced by 30% -50%, shutdown maintenance is carried out, a traditional flushing mode needs to cut off an oil supply loop of a lubricating system, the filter screen is disassembled for high-pressure water gun back flushing or chemical solvent soaking, single maintenance takes 2-4 hours, the operation of a platform is interrupted, and secondary pollution risks are caused, external pollutants can be introduced in the manual disassembly and assembly process, so that the cleanliness degradation of the system is aggravated.
