This invention discloses a hydraulic power module, its application, a hydraulic system, a fire truck, and a method. The hydraulic power module, used in the hydraulic system of a fire truck, is suitable for adjusting various hydraulic components. It includes a pressure signal pipeline for monitoring the pressure values ​​of the hydraulic system and controlling the hydraulic output. The pressure signal pipeline collects dynamic pressure values ​​of the hydraulic system in real time, forming a continuous pressure feedback signal. The pressure feedback signal is compared in real time with a preset target pressure value. If the pressure feedback signal continuously deviates from the target pressure value, a fault signal is issued. This hydraulic power module, by setting multiple hydraulic power sources, allows other hydraulic power sources to provide emergency hydraulic power when one source fails, preventing loss of hydraulic power, improving the stability of the hydraulic system, and providing emergency hydraulic power support. The accumulator absorbs pressure signal peaks, stabilizing the pressure signal.

This invention discloses a flow control method, system, storage medium, and device for excavator breakers. The invention adopts a current-to-break level correlation control approach, linking the main pump current with the break level. It is no longer subject to constant power limitation, but only sets a maximum power (i.e., the current engine power) for monitoring. When the nitrogen pressure increases with the impact work, if the current output power of the main pump is less than the current engine power and the difference between the two is greater than a threshold, the main pump current is not adjusted, ensuring that the output flow is basically stable, thereby ensuring a constant break frequency.

The invention discloses a silencing and filtering box body structure of a fan and a working method of the silencing and filtering box body structure, and relates to the technical field of fan equipment, and the box body structure comprises an air inlet cabin body, a working cabin body and an air outlet cabin body which are arranged from top to bottom. A labyrinth type air inlet channel and a filtering unit are sequentially arranged in the air inlet cabin body in the air flow direction. An elastic membrane of the device divides a driving cavity into two chambers which are respectively communicated with a pressure pulsation source and a first filtering cavity, and the elastic membrane can directly act on an elastic core material of a first-stage filtering module through a top opening. When the system runs, the diaphragm can be driven to move periodically by utilizing pressure pulsation of the system or external pressure pulsation, so that the filter element is automatically cleaned. The noise reduction, filtering and self-cleaning functions are highly integrated, the structure is compact, noise can be effectively reduced, vibration can be effectively isolated, the maintenance frequency is remarkably reduced through self-adaptive cleaning, and the fan operation energy efficiency and reliability are improved.
