Regularly charging nitrogen is a common practice for excavator operators who frequently utilize hydraulic breakers. However, a lack of knowledge regarding the appropriate amount of nitrogen to add is prevalent among many operators. Today, we'll delve into determining the correct quantity of nitrogen needed and the proper procedure for its addition.
When discussing nitrogen's role, a crucial component takes the spotlight: the accumulator. Filled with nitrogen, the accumulator serves to store the residual energy from the hydraulic breaker's prior impact and the recoil of the piston. This stored energy is then released simultaneously during the subsequent impact, amplifying the striking force. Essentially, nitrogen's impact lies in augmenting the striking energy, thereby directly influencing the hydraulic breaker's performance based on the quantity of nitrogen employed.
These days, the prevalence of excavator hammer breakers is on the rise. They're a common sight at numerous construction sites, playing a crucial role in both urban and rural development...
Many excavator operators are concerned about the ideal nitrogen quantity. As more nitrogen goes in, the accumulator pressure increases. Optimal working pressure for accumulators differs based on the hydraulic breaker model and external factors. Typically, it should hover around 1.4-1.6 MPa (roughly 14-16 kg), but this can vary.
Driven by a hydraulic cylinder, hydraulic pulverize achieves the purpose of crushing objects by controlling the angle between the movable jaw and the fixed jaw. Jiangtu hydraulic pulverizer uses the speed-increasing valve to hydraulically return the oil in the rod cavity of the oil cylinder to the rodless cavity and then increase the speed when the hydraulic cylinder extends outwards, reducing time spent on empty stroke. While keeping the thrust of the oil cylinder unchanged, the operating speed of the oil cylinder is increased and then the working efficiency of hydraulic pulverizer is improved.
The oil cylinder is designed to be installed upside down, which avoids bumps and scratches on the piston rod.
Insufficient nitrogen leads to reduced accumulator pressure, resulting in weaker striking force. Damaged diaphragms require complex and costly whole-unit disassembly during maintenance. Thus, it's crucial to charge nitrogen to the specified pressure to avoid these issues.
Adding excessive nitrogen results in heightened accumulator pressure. Consequently, the hydraulic oil pressure becomes insufficient to push the cylinder rod upward for nitrogen compression. This renders the accumulator incapable of storing energy, causing the hydraulic breaker to malfunction.
Important Note: Before commencing operation, ensure that newly installed or repaired hydraulic breakers are charged with nitrogen, maintaining a pressure of 2.5, ±0.5MPa. If the hydraulic breaker will be inactive for an extended period, it's crucial to release the nitrogen and seal the oil inlet and outlet ports. Avoid storing it in high-temperature conditions or environments below -20 degrees Celsius.
Hence, insufficient or excessive nitrogen both impede its normal functioning. While charging nitrogen, it's vital to employ a pressure gauge to regulate the accumulator pressure within the optimal range. Adjustments based on actual working conditions not only safeguard the components but also enhance overall work efficiency.
