产品描述

摊铺前应做好的准备工作首先是熨平板的预热和保温：

（1）作业前20～40min，应对熨平板进行预热，使其接近混合料的温度；
（2）因故停止作业时，需使用预热系统进行保温，防止熨平板冷却；
（3）用燃气进行预热熨平板时，应注意控制热量，防止局部过热而使熨平板变形。加热时，应采用间歇燃烧多次加热操作法，使其靠自身热传导均匀预热。有热风循环系统的，可采用点火燃烧和熄火热风循环交替进行加热。无论采用何种方式，每次点燃时间均不得大于10min；
（4）没有燃烧加热装置的，应逐个分别点燃@700618；
（5）预热时，要加强对燃烧情况的观察，若火焰熄灭，应即关闭燃气开关，找出起因，排除故障，并待燃气排尽后方可重新点燃；
（6）严禁在加热过程中，熨平板处于无人看管状态和向摊铺机各部喷油清洗。
其次在摊铺前，除了对机器本身各部分进行良好状况的检查外，还要根据施工要求做许多准备和调整工作。其项目有：摊铺带厚度的确定以及熨平板宽度的调整；熨平板拱度的调整；摊铺厚度的确定与熨平板的初始工作迎迎角的调整；熨平板的加热；工作速度的选择与送料汽车配合数量的确定；自动调平装置参考基准的准备。

The first preparation work to be done before paving is the preheating and insulation of the ironing plate:

(1) 20-40 minutes before homework, the ironing plate should be preheated to be close to the temperature of the mixture;

(2) When stopping work due to reasons, a preheating system should be used for insulation to prevent the ironing plate from cooling down;

(3) When using gas to preheat the iron plate, attention should be paid to controlling the heat to prevent local overheating and deformation of the iron plate. When heating, the intermittent combustion multiple heating operation method should be used to evenly preheat it based on its own heat conduction. For those with a hot air circulation system, heating can be achieved by alternating ignition combustion and shutdown hot air circulation. Regardless of the method used, the ignition time should not exceed 10 minutes each time;

(4) If there is no combustion heating device, ignite @ 700618 one by one;

(5) When preheating, it is necessary to strengthen the observation of the combustion situation. If the flame goes out, the gas switch should be turned off immediately to identify the cause, eliminate the fault, and wait for the gas to be completely discharged before reigniting;

(6) It is strictly prohibited to leave the ironing plate unattended and spray oil to clean all parts of the paver during the heating process.

Secondly, before paving, in addition to checking the good condition of each part of the machine itself, many preparations and adjustments need to be made according to the construction requirements. Its projects include: determining the thickness of the paving belt and adjusting the width of the ironing plate; Adjustment of the arch of the ironing plate; The determination of paving thickness and the adjustment of the initial working angle of attack of the ironing plate; Heating of the ironing plate; The selection of work speed and the determination of the number of feeding trucks to cooperate with; Preparation of reference benchmark for automatic leveling device.
