AS2251 and AS2301 Asphalt Screed Caterpillar


Changes in Auger Action

Usage:

AS2301 AWC
在螺旋分料器将物料从熨平板当中分散到熨平板外缘时,物料将对偏导板施力。 偏导板上的力随着螺旋分料器室中物料水平高度的变化而变化。

振动影响铺层密度以及施加在熨平板上的压力。 为了确保最佳的稳定性和平整铺层,螺旋分料器应在干扰尽可能少的情况下运转。

调整螺旋分料器的高度,使螺旋分料器叶片的下缘高于铺层调整后的厚度 50.8 mm (2 in)到 76.2 mm (3 in)。 螺旋分料器的速度应为 40 RPM。 每当摊铺机在操作时,螺旋分料器应以 40 RPM 运转。 螺旋分料器室中的物料水平高度应调整为:始终可看到螺旋分料器叶片的上半部分和螺旋分料器轴。 为获得最佳结果,应保持螺旋分料器室中的物料水平高度。 如果螺旋分料器室中物料的水平高度升高,那么匀料区中的压力将增加,熨平板将升高。 如果螺旋分料器室中物料的水平高度降低,那么匀料区中的压力将下降,熨平板将降低。
