What should I do if the temperature of the asphalt delivery pipeline in the asphalt mixing plant does not meet the requirements?
March 2, 2023
During the use stage of the asphalt mixing plant, such a problem is sometimes encountered: the temperature of the asphalt conveying pipeline does not meet the regulations, resulting in the raw materials being conveyed will directly affect the later manufacturing work. So, how could such a problem happen?

First of all, let's introduce what harm will be caused to the manufacture of asphalt mixing plants if the heating temperature does not meet the regulations. Generally speaking, when the ambient temperature rises, the viscosity of fuel oil will gradually decrease, making it more convenient during transportation. Therefore, in order to better achieve this effect, we will use the heating method during transportation.

After we checked the problem, we found that the heat transfer oil boiler was in normal operation. However, in the process of inquiring about asphalt circulation, we found that because the temperature of the asphalt delivery pipeline in the asphalt mixing plant did not meet the regulations, the asphalt in the pipeline even had condensation problems. In view of this situation, we analyze that there may be four reasons that may lead to such a thing. Each is: 1. The relative height of the low oil tank of high-temperature heat transfer oil is insufficient; 2. The inner axial force of the two pipes; 3. The high temperature heat transfer oil pipeline is too long; 4. The high temperature heat transfer oil pipeline lacks insulation measures.
Next, let's discuss this reason in detail. After the operation of the asphalt mixing plant is completed, the high-altitude heat transfer oil furnace will return to the high temperature heat transfer oil low oil tank, causing a large amount of gas to enter the high temperature heat transfer oil circulation system pipe. When the manufacturing work is carried out again, because the gas cannot be removed, the high-temperature heat transfer oil circulation system is poor, and the actual heating effect is not ideal.
Therefore, if we encounter this problem in actual work, we must immediately check the cause, and then take targeted countermeasures. For many reasons mentioned above, we can take effective measures to solve it. If the temperature of the asphalt mixing plant is low, certain insulation measures must be taken for the high temperature heat transfer oil pipeline.
