For masters who often operate excavators, adding nitrogen is a task that cannot be avoided. Regarding how much nitrogen should be added, many excavator masters do not have a clear concept, so today we will discuss how much nitrogen should be added.
Why add nitrogen?
To talk about the role of nitrogen in the breaker, we have to mention an important component – the energy accumulator. The energy accumulator is filled with nitrogen. The hydraulic breaker uses the remaining energy and the energy of the piston recoil during the previous blow. Store it and release the energy at the same time during the second strike to increase the strike capability. In short, the effect of nitrogen is to amplify the strike energy. Therefore, the amount of nitrogen directly determines the performance of the breaker hammer.
How much nitrogen should be added?
How much nitrogen should be added is a question that many excavator masters are concerned about. The more nitrogen is added, the greater the pressure in the accumulator, and the optimal working pressure of the accumulator will be slightly different depending on the specifications and models of the breaker and external climate conditions. Normally the pressure value should be about 1.4-1.6 MPa (approximately equal to 14-16 kg).
What will happen if there is less nitrogen?
If insufficient nitrogen is added, the pressure in the accumulator cannot meet the requirements, which will cause the crusher to be unable to strike. And it will cause damage to the cup, an important component in the energy accumulator. If the leather cup is damaged, repair requires a full dissection, which is troublesome and costly. Therefore, when adding nitrogen, be sure to add sufficient pressure.
What happens if there is too much nitrogen?
Since insufficient nitrogen will affect the performance of the breaker, is it better to add more nitrogen? the answer is negative. If too much nitrogen is added, the pressure in the accumulator is too high, and the hydraulic oil pressure is not enough to push the cylinder rod upward to compress the nitrogen. The accumulator will not be able to store energy and the breaker will not work.
Therefore, adding too much or too little nitrogen will not make the breaker work properly. When adding nitrogen, be sure to use a pressure gauge to measure the pressure to control the accumulator pressure within the normal range, and make some adjustments based on actual operating conditions. Adjustment can not only protect the components, but also achieve good operating efficiency.
