The construction machinery hydraulic system is currently set up an intelligent device, the device of the hydraulic system a warning of some hidden features, but its scope and extent of monitoring has certain limitations, so the hydraulic system inspection and maintenance should be intelligent device monitoring results with regular inspection and maintenance combined.
1. 1250 hours inspection and maintenance forhydraulic systems
Check the filter on the filter attachments, such as metal powder too much, often marked the pump wear and tear or pull cylinder tanks, which must be diagnosed and to take appropriate measures in order to boot. Filter is found damaged, dirt accumulation, must be promptly replaced, if necessary, at the same time oil change.
2. 2500 hours inspection and maintenance for hydraulic systems
No matter the state of filter should be replaced, because it is difficult to detect with the naked eye a small filter is damaged, and if prolonged high-temperature operation should be an appropriate replacement filter in advance.
3. 31000 hours inspection and maintenance for hydraulic systems
The long-term high-temperature oil change should be appropriate ahead of time. Of course, if oil quality testing through the analysis to guide the oil change is the most economical, but should pay attention to extend the use of oil, every 100h to be detected once, in order to detect and replace the oil deterioration.
4.47000 hours and 10000 hours check and maintenance forhydraulic systems
Hydraulic system required by the professional testing, make the necessary adjustments and maintenance. According to practice, imports of hydraulic pumps, hydraulic motors to be overhauled after 10000h of work, or hydraulic pumps, motors may be damaged due to neglect on the hydraulic system is to the fate of destruction.
