Regular replacement of hydraulic oil and filters
Good hydraulic oils contain a variety of additives, which can avoid oil degeneration.
But the additives will lose their efficacy after a period of time, so the hydraulic oil should be changed regularly to ensure that the additives play a role.
The filter can only absorb a limited amount of dirt particles and other impurities from the oil.
When replacing the hydraulic filter, check whether there are metal particles or debris in the filter; if there are copper or iron scraps indicating that the hydraulic pump, hydraulic motor or valve may be damaged or will be damaged; if there are rubber, it means that the seal of hydraulic cylinder is damaged.
2. Regular discharge of tank contamination
Regular discharge of water and sediment in the tank is very important for removing impurities in the oil, but regular replacement of hydraulic oil in the whole hydraulic system is also very important. This is the only reliable way to completely remove impurities in the system, oxidized hydraulic oil and other harmful impurities.
Discharge contamination from tank of hydraulic tank every 250 working hours.
If the hydraulic oil of plunger pump is polluted, especially when the hydraulic pump or hydraulic cylinder and motor are damaged, it is necessary to replace all the hydraulic oil and clean the tank.
Keep the working area clean.
When the hydraulic oil is added to the tank or re-joined, the area around the filter cover is cleaned.
Only clean funnels or containers can be used.
Do not bring dirt into the system.
When maintaining the hydraulic system, only clean plastic plugs can be used to seal the end of the pipeline.
When maintaining hydraulic components, the worktable must be absolutely clean.
Check the use of tools, they should also be very clean.
