If you are looking for a hydraulic breaker that can handle heavy-duty tasks, the DOPRO DPTB680 is a great choice. For those in need of a more compact hydraulic breaker, It is an excellent option. This breaker is specifically designed for mini excavators and backhoes, making it ideal for smaller construction projects.
For excavator drivers who frequently use hydraulic breakers, charging nitrogen is a routine. But many excavator operators don’t know how much nitrogen should be added, so today we will discuss how much nitrogen should be added and how to add it.
Why Do We Charge The Hydraulic Breaker With Nitrogen?
When it comes to the role of nitrogen, we have to mention an important component – the accumulator. The accumulator is filled with nitrogen, which can store the remaining energy of the hydraulic breaker in the previous blow and the energy of the piston recoil, and release the energy at the same time during the second blow to increase the striking power. In short, the effect of nitrogen is to increase the strike energy. Therefore, the amount of nitrogen determines the performance of the hydraulic breaker.
