Changes in Forward Speed of the Paver
当机器的前进速度改变时,匀料区中的物料密度也会变化。 匀料区的振动频率取决于熨平板匀料板的速度。 该区域的振动频率还取决于熨平板通过混合物的速度。
当摊铺机放慢速度时,压实力较高,熨平板升高。 当摊铺机加快速度时,压实力较低,熨平板降低。
摊铺机必须以不同的速度进行作业,才能满足不同的摊铺速率、不同的摊铺宽度和不同的摊铺厚度要求。 必须避免出现不能控制的速度变化,浮动熨平板才能达到最佳性能。
摊铺机的正确速度由摊铺机的供料速率决定。 要获得最佳效果,不要停止摊铺机的行驶。
选择正确的速度后,需要调整熨平板的迎角才能获得正确的铺层厚度。 如果改变摊铺机的速度,则需要调整熨平板的迎角才能保持正确的铺层厚度。 如果摊铺机的速度提高,则需要增大迎角设置。 这样,更多物料通过匀料区,以此保持相同的铺层厚度。 如果摊铺机的速度降低,则需要减小迎角设置。 这样将限制通过匀料区的物料量,以此保持相同的铺层厚度。
