Everyone knows that in the paving operation process, it is necessary to comprehensively consider many influencing factors in order to achieve high-quality paving.

如果熨平板前料头过大，且温度过低，会对预压实和熨平板浮动带来不良影响。

If the material head in front of the ironing plate is too large and the temperature is too low, it will have a negative impact on pre compaction and floating of the ironing plate.

熨平板前保持恒量的料头有利于熨平板的浮动。

Maintaining a constant amount of material in front of the ironing plate is beneficial for the perfect float of the ironing plate.

摊铺层越厚，熨平板所受承托力越强。

The thicker the paving layer, the stronger the supporting force on the screed.

按比例控制的刮板输料器和螺旋分料器，为在熨平板前保留理想数量的料头提供了可能。

The proportional control of the scraper conveyor and spiral distributor provides the possibility of retaining the desired number of material heads before the ironing plate.

夯锤行程及夯锤速度

Ram stroke and hammer speed

夯锤行程的幅度及夯锤速度是影响摊铺料预压实与熨平板浮动的重要影响因素。

The amplitude of the ram stroke and the ram speed are important factors affecting the pre compaction of paving materials and the floating of the screed.

福格勒熨平板的夯锤行程可以设定为不同长度。夯锤的行程越长，其预压实效果和压实深度越理想。因此，应使夯锤行程的设定与摊铺厚度相匹配，以获得**正向摊铺仰角。如果夯锤行程的相对摊铺厚度设定过长，会导致熨平板负仰角，从而导致摊铺层出现裂纹，甚出现摊铺层起伏不平。夯锤速度

The hammer stroke of the Fogler ironing plate can be set to different lengths. The longer the stroke of the rammer, the more ideal its pre compaction effect and compaction depth are. Therefore, the setting of the rammer stroke should be matched with the paving thickness to obtain a positive paving elevation angle. If the relative paving thickness of the rammer stroke is set too long, it will lead to a negative elevation angle of the screed, resulting in cracks in the paving layer and even uneven paving layer. Hammer speed

夯锤速度与摊铺机行驶速度是否匹配，会对摊铺层的预压实带来巨大影响。这意味着必须调整夯锤速度使之与摊铺机行走速度匹配，或者改变摊铺机行走速度与夯锤速度匹配。但理想的比例关系很难确定，要根据具体工况进行必要调节，使熨平板摊铺仰角尽可能小，从而降低摊铺料对熨平板底板的磨损。

Whether the speed of the rammer matches the driving speed of the paver will have a significant impact on the pre compaction of the paving layer. This means that the speed of the compactor must be adjusted to match the walking speed of the paver, or the walking speed of the paver must be changed to match the speed of the compactor. However, the ideal proportional relationship is difficult to determine, and necessary adjustments should be made according to the specific working conditions to minimize the elevation angle of the screed paving, thereby reducing the wear of the paving material on the bottom plate of the screed.

熨平板硬度

Screed hardness

当对熨平板摊铺仰角做大幅度改变或单侧改变时，可能会导致熨平板出现扭转。

When making significant or unilateral changes to the paving elevation of the screed, it may cause the screed to twist.

熨平板防爬锁

Screed anti creep lock

熨平板锁定是熨平板浮动模式下摊铺机停机后，开始继续行走前执行的短暂锁定动作。此时有大约30 bar压力作用于熨平板升降油缸的活塞端，这样可避免重新开始工作时由于熨平板被抬升而造成的摊铺面凸起。

Screed locking is a brief locking action performed after the paver stops in the floating mode of the screed and before continuing to walk. At this point, approximately 30 bar of pressure is applied to the piston end of the ironing plate lifting cylinder, which can avoid the protrusion of the paving surface caused by the ironing plate being lifted when starting work again.

摊铺速度摊铺速度决定了摊铺面的预压实效果。

The paving speed determines the pre compaction effect of the paving surface.

摊铺速度和熨平板前的料头应相互匹配。

The paving speed and the material head in front of the screed should match each other.

当进行高速摊铺时，对摊铺料的消耗量很大，因此应确保摊铺料的及时供应。摊铺速度应控制在料车能够持续不间断地为摊铺机供料的范围内。

When high-speed paving is carried out, the consumption of paving materials is high, so timely supply of paving materials should be ensured. The paving speed should be controlled within the range where the hopper truck can continuously supply the paver with materials.

摊铺速度对摊铺层的预压实有着关重要的影响。应尽可能保持小摊铺仰角，这样可避免出现摊铺凸起，实现**预压实效果。而摊铺机速度与摊铺仰角成正比，因此应将摊铺速度控制在小仰角摊铺的范围内。

The paving speed has a crucial impact on the pre compaction of the paving layer. Try to maintain a small paving elevation angle as much as possible to avoid paving protrusions and achieve a pre compaction effect. The speed of the paver is directly proportional to the paving elevation, so the paving speed should be controlled within the range of small elevation paving.

振动器频率

Vibrator frequency

当进行厚层摊铺时，振动器频率会对预压实效果有一定影响。由于磨耗层需要是结构致密、平整的摊铺面，振动器的频率对磨耗层摊铺更为重要。压力梁频率与压力压力梁在脉冲液压流的驱动下上下摆动。此脉冲由安装在熨平板上的旋转分配阀产生，其频率在 58 到 68 Hz之间。液压油缸驱动压力梁作用于整个摊铺宽度。当脉冲结束后，压力梁在反向弹簧的推动下返回其原始位置。作用在压力梁上的脉冲压力大小决定压力梁的行程。

When conducting thick layer paving, the frequency of the vibrator will have a certain impact on the pre compaction effect. Due to the need for a dense and flat paving surface for the wearing layer, the frequency of the vibrator is more important for paving the wearing layer. The frequency of the pressure beam and the pressure beam oscillate up and down under the drive of pulse hydraulic flow. This pulse is generated by a rotating distribution valve installed on the screed, with a frequency between 58 and 68 Hz. The hydraulic cylinder drives the pressure beam for the entire paving width. After the pulse ends, the pressure beam returns to its original position under the push of the reverse spring. The pulse pressure acting on the pressure beam determines the stroke of the pressure beam.
