目前在筑路工程方面，沥青拌合站都会采用投料机来投放沥青改性剂，那么，沥青拌合站采用投料机与人工投放相比有怎样的优势呢?沥青拌合站采用投料机运输沥青等物料，运输安装方便，操作简单，可以有效的降低工人的劳动强度及用工成本。沥青拌合站采用机器代替人工，在降低拌合站人工成本的同时，可以提升拌合站的经济效益。沥青拌合站采用投料机，通常会采用Plc控制系统，而且还会配备称重系统，所以对于投放的沥青改性剂是可以进行准确称重的，有效提高沥青拌合站的生产效率以及产品的质量。

Currently, in road construction projects, asphalt mixing stations utilize feeders to dispense asphalt modifiers. So, what are the advantages of using feeders compared to manual dispensing in asphalt mixing stations? Asphalt mixing stations that adopt feeders for transporting asphalt and other materials offer convenient transportation and installation, simple operation, and can effectively reduce labor intensity and labor costs for workers. By replacing manual labor with machines, asphalt mixing stations can not only reduce labor costs but also enhance their economic benefits. When using feeders, asphalt mixing stations typically employ a PLC control system and are equipped with a weighing system, ensuring accurate weighing of the asphalt modifiers dispensed, thereby effectively improving the production efficiency and product quality of the asphalt mixing station.

沥青拌合站在长期使用之后，会有配件磨损的情况，要做好保养工作，同时还会有很多不利脏污需要及时处理，在清洗拌合站和拌合站耐磨配件的时候也要注意方法。要定期进行保养规程所规定项目的维护、保养作业，如清洗、润滑、加油等。拌合站开动前要先检查各控制器是否良好，停工后要用水和石子倒入搅拌筒内10-15分钟进行清洗，再将水和石子清洗出。操作人员如须进入搅拌筒内清洗时，除切断电源和卸下熔断器外，并须锁好开关箱。禁止用大锤敲打的方法清理积存在沥青拌合站筒内的混凝土，只能用凿子清理。在严寒季节，工作完毕后应用水清洗拌合站滚筒并将水泵、水箱、水管内积水放净，以免水泵、水箱、水管等冻坏。不要只注意沥青拌合站和拌合站耐磨配件的维护工作，而忽略了其清洗过程，否则时间久了日积月累会对拌合站各方面造成很大的影响。

After long-term use, the asphalt mixing plant will experience wear and tear on its components, necessitating proper maintenance. Additionally, there may be many unfavorable contaminants that need to be promptly addressed. When cleaning the mixing plant and its wear-resistant components, care must be taken with the methods used. Regular maintenance procedures, including cleaning, lubrication, and refueling, should be carried out as specified. Before starting the mixing plant, it is important to check the condition of all controllers. After shutdown, water and stones should be poured into the mixing drum for 10-15 minutes for cleaning, and then the water and stones should be removed. If operators need to enter the mixing drum for cleaning, they must lock the switch box in addition to cutting off the power and removing the fuse. It is prohibited to use a sledgehammer to knock out the concrete accumulated inside the asphalt mixing plant drum; only a chisel can be used for cleaning. In severe cold seasons, after work is completed, the mixing plant drums should be cleaned with water, and the water pump, water tank, and water pipes should be drained to prevent freezing damage. Do not only focus on the maintenance of the asphalt mixing plant and its wear-resistant components, but also neglect its cleaning process. Otherwise, over time, it will have a significant impact on all aspects of the mixing plant.

沥青拌合站影响导热油炉的因素，柴油滤清器如果没有进行及时的清洗，燃油油路不通畅的状况就会发生，断火报警信号就会对其进行警告。因此，工作人员要对柴油滤清器进行清洗，首先要从一层级滤网做起，当一层级滤网比较脏时，需要对二级滤网以及三层级滤网进行清洗。关于清洗的方法，可以将柴油泡洗以及用气吹二者结合起来。油泵喷出的油雾化不良也是一个重要的故障原因。解决方法是用更好的柴油进行替换，对油路阀和风门调节阀进行清洗。燃油喷出的连续性差，这和空气进入燃油管道有很大的关系。解决方法是：对柴油泵接触器进行控制。

Factors affecting the heat transfer oil furnace in an asphalt mixing plant include the diesel filter. If the diesel filter is not cleaned in a timely manner, fuel oil passages may become blocked, triggering a flame failure alarm signal. Therefore, staff should start by cleaning the primary filter screen. If the primary filter screen is dirty, the secondary and tertiary filter screens should also be cleaned. Regarding cleaning methods, a combination of diesel soaking and air blowing can be used. Poor atomization of the oil sprayed out by the oil pump is also a significant cause of failure. The solution is to replace the diesel with better quality fuel and clean the fuel line valve and air damper regulating valve. The poor continuity of fuel spraying is largely related to air entering the fuel pipeline. The solution is to control the diesel pump contactor.

燃油压力不足，这和正常机械磨损有很大的关系。解决方法是：调大高压油泵上的调压阀。导热油压力异常。解决方法：将燃烧器关掉，将排气阀打开。这样，循环泵就会继续运作。假如在长时间以后，压力还是没有稳定，需要让油降温，之后对过滤器进行检查。沥青搅拌设备在城市公路建设中发挥着重要作用。掌握基础的故障维修可以为生产赢得更多的时间，提高生产效率，同时也能节省一部分费用。

Insufficient fuel pressure is largely related to normal mechanical wear. The solution is to increase the pressure regulating valve on the high-pressure fuel pump. The heat transfer oil pressure is abnormal. The solution is to turn off the burner and open the exhaust valve. In this way, the circulating pump will continue to operate. If the pressure remains unstable after a long period of time, the oil needs to be cooled down, and then the filter should be checked. Asphalt mixing equipment plays an important role in urban road construction. Mastering basic fault maintenance can win more time for production, improve production efficiency, and also save some costs.
