Judgment basis and standards for lubricating oil need to be replaced
Thread Content
For the reducer oil that has not been replaced for a long time, the reducer speed is 1420. The other one is also a mixing reducer oil, and the speed is around 1200. After sampling and analysis, the following results were obtained. According to the standard GB/T511-2014, I would like to ask the senior heroes in the forum, should I replace this oil with new oil, filter it and continue to use it, or can I continue to use it?
I don't need money to replace it with new oil ;P However, after the oil has been regenerated and meets the requirements, it can still be used. It is recommended that the unit prepare a vacuum oil filter. As long as it passes the processing and meets the index requirements, it can continue to be used. Usually, new equipment of this type needs to be disassembled and cleaned. There will be mechanical impurities accumulated at the bottom of the gear box and dead corners of the oil circuit, so it must be checked and cleaned in advance. For reference.
Since the test results are normal, continue to use it.
I don’t know how big the fuel tank is. If conditions permit, you can connect an external oil filter to filter and use it at the same time to ensure that the indicators are within the specified range.
It's just a matter of money, so I'll change it if it doesn't cost much. It can also be used after filtering, especially for large units, which are filtered.
