Piston rod hydraulic system maintenance methods and methods
Piston rod For mechanized construction company, the technical condition of construction machinery is excellent or not whether the company can directly produce the direct elements. In the case of hydraulically driven construction machinery, the normal operation of the hydraulic system is a prime symbol of its superior technical condition. The hydraulic oil is qualified to ensure the reliable operation of the hydraulic system, accurate maintenance is the basis for reliable hydraulic system work.
Select the appropriate hydraulic oil, hydraulic oil in the hydraulic system plays the role of transmission pressure, lubrication, cooling, sealing, hydraulic oil inappropriate choice is the primary cause of hydraulic system shortcomings and durability decline. The hydraulic oil should be chosen according to the rules in the random "Operation Manual". When the special condition requires the use of alternative oil, its function and function should be the same as that of the original trademark. Different brands of hydraulic oil can not be mixed to prevent the onset of chemical reaction of hydraulic oil, functional changes. Dark brown, milky white, smell the hydraulic oil is a metamorphic oil, can not use the air filter.
Clean hydraulic oil is the life of the hydraulic system. Hydraulic system has many sophisticated parts, and some damping holes, and some have gaps and so on. If the solid impurities infringement will constitute a precision coupling strain, hairpin, oil blockage, endangering the safety of the hydraulic system. The general solid impurities infringe the hydraulic system are: hydraulic oil dirty; unclean fuel things; refueling and repair, careless care; hydraulic components such as scaling. From the following aspects to prevent solid impurities from violating the system:
Hydraulic oil is necessary to filter filling, fueling things should be reliable and clean. It is not possible to remove the filter at the tank fill for the purpose of going forward. Refueling staff should use clean gloves and clothing to prevent solid impurities and fiber impurities fall into the oil.
Open the hydraulic tank fuel cap, filter cover, test hole, hydraulic tubing and other parts of the composition of the oil gallery to avoid dust to reveal, open the site to completely clean before turning open. If you open the hydraulic tank fuel cap, first remove the dirt near the fuel tank cap, loosen the fuel tank cap, the eradication of debris remaining in the joints (can not be washed with water to prevent water from entering the tank), confiscated after cleaning open the fuel tank cap . For the use of wipe materials and hammers, should choose not to wipe fiber material impurities and hitting the rubber surface with a dedicated hammer. Hydraulic components, hydraulic hoses should be carefully eradicated, assembled with high-pressure wind drying. The selection of genuine packaging without missing the filter (the packaging damage, although the filter is no shortage, you can not dirty). When the oil change with the eradication of the filter, the filter element before using the wipe material carefully clean the bottom of the filter shell dirt.
Oil removal is necessary to use the system with the same trademark of the hydraulic oil, the oil temperature between 45 ~ 80 ℃, with a large flow of impurities in the system away as much as possible. Hydraulic system to be repeatedly eradicated more than three times, after each eradication, taking advantage of oil heat all its release system. Eradicate and then eradicate the filter, replace the new filter after the new oil.
