Hydraulic oil is used to transmit pressure, lubricate, cool and seal the hydraulic system, and the selection of hydraulic oil is the main reason for the early failure and durability of the hydraulic system. The hydraulic oil should be selected in the quantity specified in the "Instruction Manual". In particular, performance should be the same as the original brand. Different grades of hydraulic oil cannot be mixed to prevent chemical reactions and performance changes between hydraulic oils. Dark brown, milky, unpleasant hydraulic oil is inferior oil and cannot be used.
Preventing solid impurities from mixing with the hydraulic oil cleaned by the hydraulic system is the life cycle of the hydraulic system. Hydraulic systems occasionally have many precisions, some have damping holes, some have gaps, and so on. If solid impurities invade, it will cause precise coupling strain, card issuance, oil blockage, etc., and endanger the safe operation of the hydraulic system. The way solid impurities penetrate the hydraulic system is that the hydraulic oil is not pure and the tools are not clean. Refueling and maintenance; debits for hydraulic components, etc. The intrusion of solid impurities into the system can be prevented in the following ways:
Fueling: Hydraulic oil must be filtered and filled, and tools must be reliable and clean. The filter cannot be removed from the fuel tank to increase the speed of the fuel. Fuelers should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.
Maintenance: Remove the fuel cap, filter cover, test hole, hydraulic oil tank of the hydraulic oil pipe parts, which will cause system oil when exposed, avoid dust, and thoroughly clean the parts before opening. For example, remove the hydraulic cylinder of the fuel cap, remove the cover around the soil, loosen the bottle cap, and remove the remaining impurities in the connection area (do not rinse to prevent water from seeping into the water tank). After cleaning, open the bottle cap.
When using the wiping material and hammer head, you should choose not to remove the fiber impurities, and use a rubber hammer to hit the special hammer. Hydraulic components and hydraulic hoses should be carefully cleaned, blown with high pressure air and assembled. Choose a packed real filter element (the internal packaging is damaged, although the filter element is intact, but may not be clean). Before changing the oil, clean the filter at the same time and apply wiping material before installing the filter to carefully clean the bottom of the filter element.
