1、 Maintain lubrication system clean

Architecture Material elevator equipment The hydraulic oil in is the life of the hydraulic system. There are many precision coupling parts in the hydraulic system, some of them have damping holes Some of them have gaps, etc. if the solid impurities invade, it will cause the precision coupling parts to be pulled, jammed and blocked, which will endanger the safe operation of the hydraulic system. The common ways of solid impurities invading hydraulic system are: oil and maintenance, careless maintenance; hydraulic components desquamation, etc.

Solid impurities can be prevented from invading the system in the following aspects:

① When refueling

The hydraulic oil must be filtered and filled, and the refueling tools should be clean and reliable. You can't remove the filter at the filler port of the tank in order to increase the filling 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

Material elevator equipment Remove the oil filling cover, filter cover, inspection hole, hydraulic oil pipe and other parts of the hydraulic oil tank, so as to avoid dust when the oil duct of the system is exposed. The disassembled parts should be cleaned thoroughly before opening. For example, when removing the oil filler cap of hydraulic oil tank, first remove the soil around the oil tank cover, and after loosening the oil tank cover, remove the debris remaining in the joint part (do not wash with water to prevent water from seeping into the oil tank), and then open the oil tank cap after confirming that it is clear. If it is necessary to use wiping materials and hammers, the wiping materials that do not remove fiber impurities and special hammers with rubber attached to the striking surface should be selected.

Hydraulic components and hydraulic hose should be carefully cleaned, dried with high-pressure air and then assembled. We should choose the well packaged genuine filter element. When changing the oil, clean the filter at the same time. Before installing the filter element, we should carefully clean the dirt at the bottom of the filter housing with wiping materials.

2. Do a good job in cleaning the hydraulic system

The cleaning oil must use the same brand of hydraulic oil as that used in the system. The oil temperature is between 45 ℃ and 80 ℃. The impurities in the system should be taken away with large flow rate as far as possible. The hydraulic system should be repeatedly cleaned for more than three times. After each cleaning, all the hydraulic system should be discharged when the oil is hot. After cleaning, clean the filter and replace it with new oil.

Finally, the conclusion is as follows Building material hoist equipment Hydraulic system to do a good job in regular maintenance, can not be negligent; because it directly affects the working efficiency and the service life of the lifting platform, please remember!
