目前在筑路工程方面，瀝青拌合站都會(huì)采用投料機(jī)來投放瀝青改性劑，那么，瀝青拌合站采用投料機(jī)與人工投放相比有怎樣的優(yōu)勢(shì)呢?瀝青拌合站采用投料機(jī)運(yùn)輸瀝青等物料，運(yùn)輸安裝方便，操作簡單，可以有效的降低工人的勞動(dòng)強(qiáng)度及用工成本。瀝青拌合站采用機(jī)器代替人工，在降低拌合站人工成本的同時(shí)，可以提升拌合站的經(jīng)濟(jì)效益。瀝青拌合站采用投料機(jī)，通常會(huì)采用Plc控制系統(tǒng)，而且還會(huì)配備稱重系統(tǒng)，所以對(duì)于投放的瀝青改性劑是可以進(jìn)行準(zhǔn)確稱重的，有效提高瀝青拌合站的生產(chǎn)效率以及產(chǎn)品的質(zhì)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.

瀝青拌合站在長期使用之后，會(huì)有配件磨損的情況，要做好保養(yǎng)工作，同時(shí)還會(huì)有很多不利臟污需要及時(shí)處理，在清洗拌合站和拌合站耐磨配件的時(shí)候也要注意方法。要定期進(jìn)行保養(yǎng)規(guī)程所規(guī)定項(xiàng)目的維護(hù)、保養(yǎng)作業(yè)，如清洗、潤滑、加油等。拌合站開動(dòng)前要先檢查各控制器是否良好，停工后要用水和石子倒入攪拌筒內(nèi)10-15分鐘進(jìn)行清洗，再將水和石子清洗出。操作人員如須進(jìn)入攪拌筒內(nèi)清洗時(shí)，除切斷電源和卸下熔斷器外，并須鎖好開關(guān)箱。禁止用大錘敲打的方法清理積存在瀝青拌合站筒內(nèi)的混凝土，只能用鑿子清理。在嚴(yán)寒季節(jié)，工作完畢后應(yīng)用水清洗拌合站滾筒并將水泵、水箱、水管內(nèi)積水放凈，以免水泵、水箱、水管等凍壞。不要只注意瀝青拌合站和拌合站耐磨配件的維護(hù)工作，而忽略了其清洗過程，否則時(shí)間久了日積月累會(huì)對(duì)拌合站各方面造成很大的影響。

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.

瀝青拌合站影響導(dǎo)熱油爐的因素，柴油濾清器如果沒有進(jìn)行及時(shí)的清洗，燃油油路不通暢的狀況就會(huì)發(fā)生，斷火報(bào)警信號(hào)就會(huì)對(duì)其進(jìn)行警告。因此，工作人員要對(duì)柴油濾清器進(jìn)行清洗，首先要從一層級(jí)濾網(wǎng)做起，當(dāng)一層級(jí)濾網(wǎng)比較臟時(shí)，需要對(duì)二級(jí)濾網(wǎng)以及三層級(jí)濾網(wǎng)進(jìn)行清洗。關(guān)于清洗的方法，可以將柴油泡洗以及用氣吹二者結(jié)合起來。油泵噴出的油霧化不良也是一個(gè)重要的故障原因。解決方法是用更好的柴油進(jìn)行替換，對(duì)油路閥和風(fēng)門調(diào)節(jié)閥進(jìn)行清洗。燃油噴出的連續(xù)性差，這和空氣進(jìn)入燃油管道有很大的關(guān)系。解決方法是：對(duì)柴油泵接觸器進(jìn)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.

燃油壓力不足，這和正常機(jī)械磨損有很大的關(guān)系。解決方法是：調(diào)大高壓油泵上的調(diào)壓閥。導(dǎo)熱油壓力異常。解決方法：將燃燒器關(guān)掉，將排氣閥打開。這樣，循環(huán)泵就會(huì)繼續(xù)運(yùn)作。假如在長時(shí)間以后，壓力還是沒有穩(wěn)定，需要讓油降溫，之后對(duì)過濾器進(jìn)行檢查。瀝青攪拌設(shè)備在城市公路建設(shè)中發(fā)揮著重要作用。掌握基礎(chǔ)的故障維修可以為生產(chǎn)贏得更多的時(shí)間，提高生產(chǎn)效率，同時(shí)也能節(jié)省一部分費(fèi)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.
