Problems solved by technology

In very high areas, there is no work in the economic operation area, resulting in a decline in the economic performance of the power system of the paver
At the same time, as the engine speed increases, the mechanical loss of the power system will also increase; under the premise of meeting the same working conditions, the displacement of the hydraulic pump will inevitably be reduced, reducing the overall efficiency of the hydraulic system

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 As shown, in the energy-saving control method of the paver of the present invention, the process parameters such as the preset paving thickness, paving width, and paving speed during paving work are input into the control unit through the input unit such as a keyboard and the display unit. In the engine operating point configuration unit of the controller unit, the controller unit obtains the preset engine speed value accordingly, and the controller unit adjusts the paver engine according to the obtained engine preset speed value, so that the actual speed of the paver Equal to the preset speed value. The controller unit drives the adjusting rack of the paver engine through the DC motor to control the speed of the paver engine, or the controller unit directly controls the engine of the electric spray paver. In...

Abstract

The invention discloses an energy-saving control method for paver. Presetting paving thickness, paving width, and paving velocity in paving work are inputted into the collocating cell of engine working point in controller. According to it presetting rotating speed value of engine is obtained. The controller adjusts the engine of paver so that the actual rotating speed of paver is equal to the rotating speed of engine according to the presetting rotating speed value of engine obtained. The method in invention is provided with simple operation, high automaticity. It can adjust the rotating speed of engine according to the change of actual working condition so that not only the whole efficiency is improved but also it is provided with the energy saving under the presence of ensuring working performance.

Description

technical field [0001] The invention mainly relates to the field of paver in road construction machinery, in particular to an energy-saving control method of a paver. Background technique [0002] The paver equipped with a diesel engine as a power unit often does not work under the rated load, the actual production rate is only about 50% of the theoretical production rate, and the actual working frequency of the vibration and vibrating device is much lower than the highest frequency. However, during the paving operation, the engine is set to work at the rated speed, so that the engine can work at the fuel consumption rate g while ensuring the torque and power output. In the very high area, there is no work in the economic operation area, which causes the economic performance of the power system of the paver to decline. At the same time, as the engine speed increases, the mechanical loss of the power system will also increase; under the premise of meeting the same working co...
