Factors influencing the smoothness of pavement and measures (three)       

3, paver speed is not stable, constant speed operation can not be

The reason is: the main control technology of paver backward or defective.

Measures：

Should choose with the function of constant speed paving paver can realize constant speed paving control. The driving system of paver with this function must be the drive mode of wheel side motor and wheel side reducer. Constant speed paving paver technology is characteristic of machine, electricity, liquid, instrument integration control technology, generally used electronically controlled variable piston pump and variable motor group closed loop walking track; independent drive; through the speed sensor wheel side reducer signal feedback to the central microcomputer controller, electronically controlled variable piston pump swashplate adjustment pendulum change the output angle of an oil pump, so as to achieve constant speed paving.

4, the paver for the uneven distribution of materials

Reasons: scraper conveyor system and screw conveyor system can not achieve automatic proportional control; material level controller quality is not stable or can not play a role.

Measures：

(1) the advanced technology of paver, drive and control system of this machine and the scraper conveyer system and screw conveyor system has two independent hydraulic drive, respectively about scraper and around the spiral conveying pipe, which can realize automatic control ratio. The height and rotation speed of the screw conveyor can be stepless adjusted, and the mixture of the opposite direction, the opposite direction and the same direction can be realized.

(2) the quality of a material scraper controller and screw conveyor system materiallevel controller should be reliable; mechanical pendulum type material level controller should be responsive, high reliability controller or ultrasonic sonar installation; material level controller.
