How to maintain the electric scraper to extend the service life

At present, industrial and mining electric scrapers are mainly maintenance, in order to meet the needs of high reliability and long life of industrial and mining electric scrapers, proactive preventive maintenance should be taken. Proactive preventive maintenance is the maintenance work carried out when the hydraulic system is working normally, mainly including:

1. Determine the target cleanliness that can extend the life of hydraulic components and systems. Practice has proved that when the pollution of the system is lower than NAS9 level, there is basically no failure, and when the pollution degree exceeds NAS10 level, there is often a failure. The pollution degree of the electric scraper should be controlled at NAS9-NAS10 level.

2, maintain good filtration to control the pollution of the oil, so that the pollution of the oil reaches a dynamic balance within the range of the target cleanliness. At present, the main means is to filter the hydraulic oil, and the filter should choose a reasonable filtration accuracy, and require frequent replacement.
