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.
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.
The breaker hammer is an important accessory of the excavator, and the correct use of the breaker is crucial to the life of the excavator. This time, the editor brings the correct selection method of the breaker drill rod.
First remove the breaker return pin and rock breaker drill rods pin, reinstall the rock breaker drill rods, and insert the rock breaker drill rods
The operation of the excavator sheet pile driver can be completed by one excavator driver. The same set of equipment is used for piling and pulling. The operation between piling and pulling is fast, with good mobility, and there is no need to disassemble and assemble the transfer site.
The heat treatment process of the breaker hammer drill rod is preferably quenched as a whole and tempered in sections. The HRC hardness value of the impact part of the drill rod is 56-58, and the HRC of the impact part of the piston is 45-48.
