What are the maintenance techniques for mobile lifts?
1. Keep the hydraulic system clean
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 holes, some have gaps, etc.; if solid impurities invade, it will cause fine couples to be injured, hairpin, oil passage blockage, etc., endangering the safe operation of the hydraulic system. ---The way in which solid impurities invade the hydraulic system are: refueling and repairing, careless maintenance; hydraulic components, etc.
The solid impurities can be prevented from invading the system from the following aspects:
① When refueling
The hydraulic oil must be filtered and refilled, and the refueling items should be clear and reliable. We cannot remove the filter at the fuel filler opening of the fuel tank in order to improve the fueling speed. Refueling personnel 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 filler cap, filter cover, detection hole, hydraulic tubing and other parts of the mobile elevator caused the system oil passage to be exposed to avoid dust, and the dismantled parts must be completely cleared before they can be opened. For example, when disassembling the hydraulic oil tank filler cap; first remove the dirt around the fuel tank cap, unscrew the fuel tank cap, and remove the debris remaining at the joints (you cannot rinse with water to prevent water from seeping into the fuel tank). . 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. Hydraulic components and hydraulic hoses should be carefully cleaned and assembled after being dried with high-pressure air. We need to choose a well-packed filter element, and clean the filter at the same time when changing the oil. Before installing the filter element, use scrubbing materials to carefully clean the bottom dirt in the filter housing.
Second, do a good job of cleaning the hydraulic system
The cleaning oil must use the same hydraulic oil as that used in the system. The oil temperature is 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 the oil while the oil is hot. After cleaning, clean the filter, replace with a new filter and add new oil.
