Excavator breaking hammer flow control method and system, storage medium and equipment
The invention discloses an excavator breaking hammer flow control method and system, a storage medium and equipment, a current and breaking grade association control thought is adopted, the current of a main pump is associated with the breaking grade, constant power limitation is not needed any more, only the maximum power (namely the current power of an engine) is set for monitoring, and the maximum power of the breaking hammer is set for monitoring. When the nitrogen pressure rises along with striking work, if the current output power of the main pump is smaller than the current power of the engine, and the difference value between the current output power and the current power is larger than the threshold value, the current of the main pump is not adjusted, the output flow is basically stable, and then the crushing frequency is constant.
本发明公开了一种挖掘机破碎锤流量控制方法、系统、存储介质及设备，本发明采用电流与破碎等级关联控制思路，将主泵电流与破碎等级进行关联，不再受恒功率限制，只设定一个最高功率（即发动机当前功率）进行监控，当氮气压力随着打击做功出现温升时，若主泵当前输出功率小于发动机当前功率、且两者的差值大于阈值时，主泵电流不进行调节，保障输出流量基本稳定，进而保障破碎频率的恒定。
