Digital Hydraulic Paver
The first digital hydraulic paver
Paver is an indispensable pavement construction machinery in road engineering construction, and its performance and reliability will directly affect the quality of the whole pavement engineering. With the progress of modern construction technology and the continuous improvement of the quality of modern construction pavement, the performance of paver is also put forward higher and higher requirements. Digital hydraulic is the common basic technology to realize the innovation and development of road construction machinery. | The hydraulic system of paver is based on digital programmable power sensitive pump, which not only reduces the energy consumption of the whole machine, but also realizes efficient work. | |
The spreading speed and steering of the paver are controlled by the digital hydraulic motor which drives the two tracks. Because the digital hydraulic motor can accurately control their rotational speed and rotation angle, the paver can automatically turn and run at different speeds according to the predetermined trajectory, and realize the intelligent (unmanned) paving operation. ?? Double track running error??< 0.1% ?? Minimum stable running speed: better than 0.2 m / s ?? Running repeat positioning accuracy: better than 5 mm | The paver engine is also controlled by AEMETEC using ECU developed by highly reliable reconfigurable logic devices to further achieve high efficiency and energy saving. | |
The pitch angle of the ironing plate of the paver is adjusted by digital hydraulic cylinder (DHC). According to the comprehensive situation, ECU can change the pitch angle of ironing plate by controlling the precise displacement of digital cylinder, and finally accurately control the thickness and evenness of paving asphalt. ?? Pitch angle DHC resolution accuracy: 0.5mm ?? Pitch angle DHC running speed range: 0.5 - 20 mm / s arbitrary adjustment | The digital hydraulic drive control system of paver makes pavement construction machinery move towards the era of digitization, information and intelligence. | |
According to the spreading speed, paving layer thickness, width and other parameters, the material distribution control system accurately controls the material distributor driven by digital hydraulic motor to realize the automatic transportation and distribution of paving materials. | ||
