Preventing solid impurities from mixing into the hydraulic system. There are many precision parts in the hydraulic system. If solid impurities invade the damping holes or the gaps of the parts, it will cause strains on the precision parts, blockage of the oil passage, etc., endangering the safe operation of the hydraulic system. Generally, the reason why solid impurities invade the hydraulic system is due to the unclean hydraulic oil; unclean refueling tools; careless refueling and repair and maintenance; desquamation of hydraulic components. It can prevent solid impurities from invading the system from the following three aspects:

1. When refueling the waste paper baler. The hydraulic oil must be filtered and refilled, and the refueling tools should be kept clean. The filter at the fuel tank filler opening cannot be removed in order to increase the fueling speed. Fueling personnel should use clean gloves and work clothes to prevent solid impurities and fiber impurities from falling into the oil.

2. When cleaning the waste paper baler. The cleaning oil must use the same brand of hydraulic oil as the system used, the oil temperature is between 45-80 degrees Celsius, and the large flow rate is used to remove impurities from the system as much as possible. The hydraulic system should be cleaned more than three times repeatedly. After each cleaning, let it out of the system while the oil is hot. After cleaning, clean the filter, replace the new filter element and add new oil.
3. When the waste paper baler is maintained. When disassembling the hydraulic oil tank filler cap, filter cap, inspection hole, hydraulic oil pipe and other parts, pay attention to avoiding dust when the system oil passage is exposed. The disassembled parts must be thoroughly cleaned before opening. For example, when removing the hydraulic fuel tank filler cap, first remove the soil around the fuel tank cap. After loosening the fuel tank cap, remove the debris remaining in the joint (not flush with water to prevent water from leaking into the fuel tank), and then open the fuel tank cap after confirming that it is clean.
If you need to use a wiping material and a hammer, be careful to choose a wiping material that does not remove fiber impurities and a special hammer with rubber attached to the striking surface. The hydraulic components and hydraulic hoses should be carefully cleaned and assembled after drying with high-pressure air. Use genuine filter elements with intact packaging (the inner packaging is damaged, although the filter element is intact, it may be unclean). Clean the filter at the same time when changing the oil. Before installing the filter element, use the wipe material to carefully clean the bottom dirt in the filter housing
