Many people are not unfamiliar with the five major pieces of excavators, but if you ask them how to do proper maintenance, it may not be clear. Proper maintenance of the excavator can keep the excavator in good working condition and increase the life of the excavator. Therefore, this is an important thing.
Excavator engine
1: The engine oil and the oil filter element must be genuine parts and replaced according to the prescribed maintenance cycle. The old machine needs more care, and the replacement time of the oil filter can be shortened as appropriate to make the engine life longer.
2: Use diesel fuel provided by regular gas stations as much as possible. Even if the diesel fuel is added by regular gas stations, do not directly add it to the fuel tank. Filter before adding. Drain water at the bottom of the diesel tank and at the oil-water separator before starting work every day. Buy genuine parts for the diesel filter, and replace the diesel filter according to the specified maintenance cycle.
3: The air filter element is often checked. When the outer filter element is dusty, use compressed air to blow from the inside to the outside. The air pressure should not be too large to prevent the filter element from being blown. The internal filter cannot be cleaned. After the external filter is washed 2 or 3 times, replace it with the internal filter at the same time.
4: Do not use idling for a long time in order to save fuel to prevent carbon deposition.
Excavator hydraulic
1: Replace the hydraulic oil, oil return filter element, pilot filter element according to the specified maintenance cycle, and pay attention to whether there is iron or copper debris adsorbed on the filter element. When using a breaker, the deterioration and deterioration of hydraulic oil accelerates, and the replacement cycle should be shortened.
2: Do not work for a long time without oil.
3: After replacing hydraulic oil or hydraulic components, pay attention to exhaust air.
Excavator Electric
1: Pay attention to waterproofing, do not involve deep water operations, and do not directly rinse electrical components with water when doing cleaning.
2: Do not stack debris, especially metal tools, in the battery box, which may cause fire.
3: Do not replace the insurance with iron or copper wire, and do not replace it with non-standard insurance.
4: When the excavator is parked for a long time, the battery cable should be removed to prevent feeding.
Excavator Machinery
1: Rotary reducer and walking reducer change gear oil periodically. In the overall structure of the excavator, the gear plays an important role in color. Once a crack appears on the gear surface of the excavator, the maintenance personnel must repair the gear at the first time.
2: Pay attention to the cleaning of dirt and debris on the pin part. Adding butter. In the overall structure of the excavator, the gear plays an important role. Once the surface of the gear of the excavator is cracked, the maintenance personnel must repair the gear at the first time.
3: When wading operation, when the water overflows the rotating ring gear, pay attention to replace the butter in the rotating ring gear.
4: Pay attention to the rust prevention of the cylinder rod.
5: When the excavator is parked for a long period of time, apply grease to the exposed (exposed) metal parts to prevent rust.
Excavator structure
1: Check the pin bolts for looseness, shedding, and missing every day, and tighten them in time.
2: Check the structure daily for cracks and deformation.
3: Pay attention to the surrounding environment when parking the excavator, park on a solid, stable and hard ground, do not park on the river, cliff, or under the slope to prevent accidents.
4: The bucket cylinder is fully retracted when parked, and the bucket falls to the ground to prevent the cylinder from being hit. The basic contents include: equipment maintenance, equipment inspection and equipment repair.
