3. Prevent solid impurities from mixing into the hydraulic system
Clean hydraulic oil is the life of the hydraulic system.There are many precision couplings in the hydraulic system, some with damping holes or crevices.If solid impurities invade, precision accidental injuries, hairpins, blockages in oil pipelines, etc. will endanger the safe operation of the hydraulic system.General ways of solid substance intrusion are: dirty hydraulic oil; dirty refueling tools; inadvertent refueling and maintenance; debris of hydraulic components, etc.Solid impurities can be prevented from invading the system in the following ways:
(1) Hydraulic oil must be filtered during filling and the filling tools should be reliable and clean.It is not possible to remove the filter at the filling opening of the hydraulic tank in order to increase the filling speed.Fueling personnel should use clean gloves and work clothes.
(2) Remove the filling cap, filter cap, detection hole, hydraulic oil pipeline etc. of the hydraulic tank during maintenance. Avoid dust lifting when the oil pipeline of the hydraulic system is exposed. The disassembly part must be thoroughly cleaned before opening.If you disassemble the oil tank cap, remove the dirt around the cap, unscrew the cap and remove the debris that remains in the joint (you cannot rinse it with water to prevent water from seeping into the tank), and confirm that the cap is clean before you open it.When using abrasive materials and hammers, select a special hammer that does not remove fibre impurities and that attaches rubber to the strike surface.Hydraulic components and hoses should be carefully cleaned and dried with high pressure air before assembly.Choose genuine filters with good packaging (if the package is damaged, the filters may be dirty even though they are intact).Clean the filter at the same time when changing the oil, and carefully remove the dirt inside the filter housing by applying abrasive material before installing the filter cartridge.
(3) The cleaning oil of the hydraulic system must use the same type of hydraulic oil as that used in the system. The temperature of the oil is between 45-80 C, and the impurities in the system should be removed as far as possible with a large flow rate.The hydraulic system needs to be cleaned more than three times repeatedly, and all of it is released from the system when the oil is hot after each cleaning.Clean the filter after cleaning, replace the new filter cartridge and add new oil.
