How to love and care for mobile lifts
A total of the following points.
1、Cautions in operation
Mechanical operations should be soft and smooth, mechanical operations should avoid rough, otherwise it is bound to produce shock loads, so that mechanical failure is frequent and greatly shorten the service life. The impact load generated during operation, on the one hand, the mechanical structure early wear, fracture, broken, on the one hand, the hydraulic system to generate impact pressure, impact pressure will cause damage to hydraulic components, oil seals and high-pressure hose joints and hose pressure at premature failure of oil leakage or burst pipe, relief valve frequent action oil temperature rise.
2, to prevent air and water intrusion into the hydraulic system
Hydraulic oil at atmospheric pressure and temperature contains a volume ratio of 6 to 8% of air, when the pressure is reduced air will be free from the oil, bubble rupture so that the hydraulic components “cavitation”, producing noise. A large amount of air into the oil will make the “cavitation” phenomenon intensified, the hydraulic oil compressibility increased, work instability, reduce efficiency, the implementation of the work of components “crawl” and other adverse consequences. In addition, the air will also make the hydraulic oil oxidation, accelerate the deterioration of the oil.
3、Choose the suitable hydraulic oil
Hydraulic oil in the hydraulic system plays a role in cooling, pressure transmission, lubrication, sealing, hydraulic oil is not properly selected is the main reason for early failure and durability of the hydraulic system. The hydraulic oil should be selected according to the grade specified in the random “instruction manual”, and when special circumstances require the use of substitute oil, the performance should be the same as the original grade. Different grades of hydraulic oil should not be mixed to prevent chemical reaction and performance change of hydraulic oil. Milky white, dark brown, odorous hydraulic oil is deteriorated oil, can not be used.
4、Prevent solid impurities from being mixed into the hydraulic system
Clean hydraulic oil is the life of the hydraulic system.
There are many precision couples in the hydraulic system, some have small damping holes, some have gaps and so on. If the invasion of solid impurities will cause the precision coupling strains, card, blockage of the oil channel, etc., endangering the safe operation of the hydraulic system. General solid impurities invade the hydraulic system through: unclean fueling tools; unclean hydraulic oil; hydraulic components off chip; fueling and repair, maintenance carelessness, etc..
5, hydraulic oil maintenance and cleaning
Cleaning oil must be used with the same grade of hydraulic oil used in the system, oil temperature between 45 ~ 80 ℃, with a high flow as far as possible to take away the impurities in the system. Hydraulic system should be repeatedly cleaned more than three times, after each cleaning, while the oil is hot, all of them will be released from the system. After cleaning, clean the filter and replace it with a new filter element and fill it with new oil.
