An important part of the hydraulic breaker is the accumulator. The accumulator is used to store nitrogen. The principle is that the hydraulic breaker stores the remaining heat from the previous blow and the energy of the piston recoil, and in the second blow. Release energy and increase the blow strength, so the blow strength of the hydraulic breaker is directly determined by the nitrogen content. The accumulator is often installed when the breaker itself cannot reach the hitting energy to increase the hitting force of the breaker. Therefore, generally small ones do not have accumulators, and medium and large ones are equipped with accumulators.
1.Normally, how much nitrogen should we add?
Many buyers want to know how much nitrogen should be added to the purchased hydraulic breaker. The best working state of the accumulator is determined by the hydraulic breaker model. Of course, different brands and models have different external climates. This leads to a difference. Under normal circumstances, the pressure should be around 1.3-1.6 MPa, which is more reasonable.
2.What are the consequences of insufficient nitrogen?
Insufficient nitrogen, the most direct consequence is that the pressure value of the accumulator does not meet the requirements, the hydraulic breaker is weak, and it will damage the components of the accumulator, and the maintenance cost is high.
3.What are the consequences of too much nitrogen?
Is more nitrogen, the better? No, too much nitrogen will cause the pressure value of the accumulator to be too high. The hydraulic oil pressure cannot push the cylinder upward to compress the nitrogen, and the accumulator cannot store energy and cannot work.
In conclusion，Too much or too little nitrogen can not make the hydraulic breaker work normally. Therefore, when adding nitrogen, a pressure gauge must be used to measure the pressure, so that the pressure of the accumulator can be controlled in the normal range, and a little can be done according to the actual working conditions. Adjust, so that it can not only protect the components of the energy storage device, but also achieve good work efficiency.
