Selection and replacement of excavators hydraulic oil

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.

The reason why the excavator hydraulic piston is always bad

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.

Excavator hydraulic piston leaks, the consequences are very serious

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?

Excavator hydraulic cylinder maintenance details revealed

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.

Daily maintenance of excavator hydraulic cylinder

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.

The reason of excavator breaker hammer stops hitting during the working process

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.

Several situations of fracture of excavator breaker hammer steel brazing

There are roughly two situations for the fracture of the excavator breaker hammer steel brazing:

Four Standard Operating Procedures for excavator sheet pile drivers

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.

Operation specification for excavator vibratory pile driver

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;

What are the advantages and characteristics of excavator vibrating hammers

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.

What fields are excavator vibrating hammers used in?

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.

Correct choice of cleaning agent to double the life of the excavator pile hammer

We all know that excavator pile hammer basically work outdoors because of their work content, and some of them are not paved roads, and the dust is also serious during drilling operations, and it is easy to be contaminated with sand and dust, which will continue to rise over time.
