Maintenance steps of mobile elevator
Today's rapid economic development has also seen many aerial operations. Traditional scaffolding no longer satisfies people's needs. Traditional scaffolding is a huge expense both in terms of labor cost and cost of things, and the scaffolding is far away. There is no aerial vehicle safety. Therefore, the emergence of aerial work vehicles can be said to completely replace scaffolding. Because of this, the emergence of aerial work trucks has quickly occupied the mall, so what are the maintenance steps of the mobile elevator?
The hydraulic oil in the mobile elevator is the life of the hydraulic system. There are many fine couples in the hydraulic system, some have damping small holes, and some have gaps, etc.; if solid impurities invade, it will cause fine couples to be injured, hairpin, blockage of oil passage, etc., endangering the safe operation of the hydraulic system. The general solid impurities invade the hydraulic system through: refueling and maintenance, careless maintenance; hydraulic components, etc.
The solid impurities can be prevented from invading the system from the following aspects:
① When refueling
The hydraulic pressure should be filtered and filled, and the refueling should be cleaned reliably. No one can remove the filter at the filler port of the fuel tank in order to increase the refueling speed. Oilers should use clean gloves and work clothes to prevent solid impurities and fiber impurities from falling into the oil.
② During maintenance
The disassembly of the hydraulic oil tank refueling cap, filter cover, detection hole, hydraulic tubing and other parts of the mobile elevator causes the system oil channel to be exposed to dust, and the dismantled parts must be thoroughly cleaned before being turned over. For example, when disassembling the hydraulic oil tank refueling cap; first remove the dirt around the oil tank cap, loosen the oil tank cap, and remove the debris remaining at the joints (do not wash with water to prevent water from entering the oil tank), and only open the fuel tank cap after confirmation. If you need to use scrubbing materials and hammers, you should choose scrubbing materials that do not remove fiber impurities and special hammers with rubber attached to the hitting surface.
Second, do a good job of cleaning
The cleaning oil should use the same hydraulic oil as that used in the system. The oil temperature should be between 45 and 80°C. Use large flow to remove impurities from the system as much as possible. The hydraulic system should be cleaned repeatedly more than three times. After each cleaning, release all of the oil while the oil is hot. After cleaning, clean the filter, replace with a new filter and add new oil.
