In the usual common hydraulic lift products, many times involve hidden installation requirements, then this approach is bound to cause some hidden dangers in the health of the late, especially our hydraulic lift products, Jinan Lulong Xiaobian to everyone today in detail introduce:
First, prevent solid impurities from mixing into the hydraulic system: Clean hydraulic oil is the lifeblood of the hydraulic system. There are many precision parts in the hydraulic system, some have small holes, some have gaps, and so on. If the solid impurities intruded will cause the precision joints to be damaged, hairpins, oil channel blockage, etc., endanger the safe operation of the hydraulic system. Common solid impurities invade the hydraulic system through: impervious hydraulic oil; impure cleaning tools; inadvertent refueling and maintenance, carelessness; and descaling of hydraulic components.
Second, to prevent air from invading the hydraulic system: Under normal atmospheric pressure, the hydraulic oil contains 6 to 8% of the volume of air. When the pressure decreases, the air will be released from the oil, and the air bubbles will burst to make the hydraulic components “cavitationâ€. Generate noise. The large amount of air entering the oil will increase the phenomenon of “cavitationâ€, increase the compressibility of the hydraulic oil, make the work unstable, reduce the work efficiency, and cause adverse effects such as “crawling†on the actuator. In addition, the air will also oxidize the hydraulic oil and accelerate the deterioration of the oil.
Third, to prevent water intrusion into the hydraulic system: the oil contains excessive water, which will cause corrosion of the hydraulic components, deterioration of the oil emulsion, decrease of the strength of the lubricant film, and acceleration of mechanical wear. In addition to preventing moisture intrusion during maintenance, care must be taken to store oil. When the bucket is not in use, it is necessary to tighten the lid, preferably to place it upside down. Oil with a large amount of water must be filtered several times. Each time the filter is replaced, the filter paper should be replaced. When there is no special instrument, the oil can be dripped to the hot On the iron plate, no steam will emerge and burn immediately.
