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.

The application discloses a self-pressurizing gear pump and relates to the technical field of hydraulic pumps.The main structure is that oil channel a and oil channel b are arranged in the side walls of the "8"-shaped installation cavities on the meshing starting side and the meshing separating side;the upper surface of the lower distribution disc is provided with a lower distribution waist-shaped port a communicated with the variable volume cavity on the meshing starting side and a lower distribution waist-shaped port b communicated with the variable volume cavity on the meshing separating side;one end of the oil channel a is communicated with the lower distribution waist-shaped port a through the lower oil channel a arranged in the lower distribution disc;and one end of the oil channel b is communicated with the lower distribution waist-shaped port b through the lower oil channel b arranged in the lower distribution disc.The self-pressurizing gear pump provided by the application utilizes the fact that the volume of the inner wall of the "8"-shaped cavity and the tooth top circle of the gear on the meshing side becomes smaller when the gear continuously meshes and rotates, so that the first-stage pressurization of the oil is realized;and the oil is extruded to realize the second-stage pressurization by the reduction of the volume of the variable volume cavity formed when the gear continuously meshes, so that the output pressure is greatly improved.

A parallel dual-head four-cylinder plunger pump. This invention aims to solve the problems of existing pumps, such as difficult installation, low installation efficiency, difficulty in increasing and adjusting output flow, and large size of the working device. The technical solution includes a pump head, a first motor, a second motor, a first plunger pump body, a second plunger pump body, a third plunger pump body, a fourth plunger pump body, a first plunger, and a second plunger. Each pump head has an outlet channel and an inlet channel. The first and second plunger pump bodies are symmetrically mounted on the front of the pump head, and the third and fourth plunger pump bodies are symmetrically mounted on the back of the pump head. The first plunger slides with both the first and second plunger pump bodies, and the second plunger slides with both the third and fourth plunger pump bodies. The first motor is mounted on the first and second plunger pump bodies and drives the first plunger. The second motor is mounted on the third and fourth plunger pump bodies and drives the second plunger.
