The replacement of the excavator oil seal kit in the central rotary joint and the oil seal in the boom cylinder on the excavator is time-consuming and labor-intensive, and cannot be quickly replaced and repaired in the field due to the limitations of the site and equipment.
According to statistics, about 70% of the failures of the hydraulic system of excavators are caused by improper selection of excavators hydraulic oil, careless use and untimely replacement.
When the working device is not fully retracted, the bucket can easily hit the rock, and the piston rod of the excavator hydraulic piston will generate a large load, resulting in damage to the inside of the oil cylinder and cracking around the pin shaft.
So what are the reasons for the oil leakage of the excavator hydraulic piston? What should we pay attention to when using excavators to avoid oil leakage of hydraulic cylinders?
The particularity of the working environment of excavators, therefore, should be paid more attention to in daily maintenance. When it comes to the maintenance of the excavator hydraulic cylinder, everyone must know that the purpose is to prevent the hydraulic oil from being polluted.
Hydraulic oil should be replaced regularly during the use of the excavator hydraulic cylinder, and the system filter should be cleaned to ensure cleanliness and prolong service life.
Reversing valve card. After the excavator breaker hammer was disassembled and inspected, it was found that other parts were in good condition. After checking the reversing valve, it was found that its sliding and astringent were more likely to be issued.
There are roughly two situations for the fracture of the excavator breaker hammer steel brazing:
Excavator sheet pile drivers are mainly used for piling. The types of piles include pipe piles, steel sheet piles, steel pipe piles, prefabricated concrete piles, wood piles and photovoltaic piles driven on water.
The excavator vibratory pile driver is mainly used for piling, and the types of piles include pipe piles, steel sheet piles, steel pipe piles, concrete prefabricated piles, wood piles and photovoltaic piles driven on water;
The excavator vibrating hammers is an environmentally friendly pile machine. Compared with electric hammers and diesel hammers, high-frequency hydraulic vibrating hammers have less vibration and noise during construction, and do not disturb the people.
The principle of excavator vibrating hammers technology is to generate up and down vibration through the relative motion of two eccentric gears, so that the object being acted on is separated from the surrounding soil layer, reducing frictional resistance and achieving the purpose of sinking and pulling.
