What are the hydraulic hammer of mechanical shovels?
The main use of hydraulic hammers of mechanical excavators is to break and break all kinds of small and large stones, which are used to separate them from the rocks of the mountains, as well as to destroy concrete structures, asphalt roads, and also many actions that are done to dig tunnels. Due to the very precise and unique performance and efficiency of the hydraulic circuit and hydraulic hammer parts, as well as the increase in fluctuations during the drilling process, the installation and maintenance of the Picor system is done in accordance with the standards of the manufacturing company.
How the hydraulic hammer works
By installing hydraulic hammers on mechanical excavators and loaders, by moving the piston and hitting the picker pen, a sudden force is applied to stone, concrete or any other hard objects, which leads to its destruction and disintegration. . With the movement of the piston in the cylinder, which is done through the hydraulic oil that is transferred by the hydraulic hoses from the excavator.
In this way, the hydraulic oil is transferred in the front of the piston and causes the piston to move upwards. slow When the piston moves to the highest set point, the oil is transferred to the regulator through the set channels. What the regulator does is direct hydraulic oil to the front of the piston, which causes the piston to drop suddenly and hit the picor pen.
What is the importance of gas?
When the piston moves up. At the end, the piston enters the upper head chamber, which contains compressed nitrogen gas. In this way, when it opens in front of the piston and the piston moves downward, it moves with more power and acceleration, and its impact is entered with the pen, which ultimately leads to its further destruction.
Safety Tips
When using picor or when repairing and servicing hydraulic hammer, you should pay attention to important safety points. When using the picker, it gets very hot, so you should avoid touching the tip of the pen.
While working with the hydraulic hammer, it is necessary that the pressure of the mechanical excavators on the picker should not be too high that the front of the long excavator to be Also, it should not be so low that the pen takes on a relief state.
You should keep in mind that when the gassing of the upper head moves under the influence of the gas pressure of the piston in the cylinder and hits the pen. In this case, you should avoid standing in front of the pen while gassing.
When separating the picker from the excavator, it is better to note that the hydraulic valves next to the stick of the machine are tight.
