Application of PLC in asphalt mixing station

weighting-system-300x197.jpgThe surface of the oil slick on the asphalt surface is because there are more bubbles produced by the emulsification process, and the bubble ruptures and remains on the surface, forming the surface of the oil slick.
If the surface of the oil slick is not very thick, stir before use can dissolve, if the latter words need to be added to the appropriate defoamer or slow stirring, etc., can be eliminated.

From the above content can be seen, it is precisely because of the heating, heat from the hot end of the continuous transfer to the cold end, and which and then passed to the hot end, so that the continuous circulation, so as to meet the asphalt mixing station in the process of the relevant requirements, to achieve the requirements of cyclic heating.

Today, with the rapid development of the Times economy, the modern expressway is gradually booming, while its most commonly used equipment is asphalt mixing equipment, asphalt mixing equipment in the actual control is mainly the control of feed, temperature control, measurement control, finished product control and dust removal control.

I wonder if your friends have learned more about the work of the asphalt mixing plant.
If you have a certain understanding, then you should know that the asphalt mixing plant equipment has a more special function, this function is to be able to carry out circulating heating, so that the asphalt products to achieve the best state.
So how is this feature implemented? Next, let's take a look at the specific introduction.

In short, in the asphalt Batch mix plant mixing plant working process, due to the realization of the cycle of antipyretic this condition, thus also ensure that our asphalt products to achieve the best state.
This not only ensures our production requirements, but also provides favorable conditions for our next production work.
Hope that through this analysis, so that we have a new understanding and understanding of this knowledge.

As far as s7-300/400 High Performance plc is concerned, not only has the fast running speed, the larger memory and the more communication interface, at the same time the quantification feeder programming is compatible with the STEP7, the program is not used as one-sided modification.

  Therefore, in the production process of asphalt mixing equipment, it is necessary to predict the results in advance, pay attention to the production of the whole system, reasonable control of temperature, reduce or eliminate waste.

In fact, it is very normal for bitumen to precipitate during existence, and this is not treated as long as the requirements are met.
However, if it does not match the requirements of use, oil and water separation can be used to deal with it.
Asphalt will have precipitation, because the density of water fragrance is relatively small, so that the emergence of stratification phenomenon.

.

  In addition to the above two factors, the moisture content of raw materials is also an important factor that can not be ignored.
If the water content of raw materials is high, the temperature control in the production process of asphalt mixing equipment is also very difficult.
In addition, technology such as combustion systems, fuel pump pressure and injection volume can also have an impact on the temperature of the mixture.
If there are problems such as wear, leakage or blockage in the combustion system, the performance of the system will be reduced.

  In the working process of asphalt mixing equipment, the quality of the mixture is often related to the final quality of the construction.
Therefore, we need to improve the quality of the mixture as much as possible, and the temperature of the mixture is one of the criteria for the conformity assessment of the mixture.
That is, if the temperature is too high or too low, it will make the mixture into waste, can not meet the needs.

The use of emulsified asphalt produced by asphalt mixing equipment is very extensive, but there is a precipitation phenomenon in the process of storage, which is normal phenomenon? What causes this phenomenon to occur?

In the process of evaporation, because there will be a pressure difference in the asphalt mixing plant equipment, under the action of pressure difference, these steam will flow to the cold end of the heat pipe at a very high speed, and then by the which release of latent heat and condensation occurs.
We know that because of the effect of the suction core capillary suction, these condensate will return from the cold end to the hot end again.

The current highway engineering, is generally a big investment in the project.
In the actual project construction, it is necessary to control the cost of the project.
The control and management of production cost of asphalt mixing station in highway engineering is of great effect on the cost of controlling the whole highway project, because the main cost of highway engineering is concentrated on the mixing station, and almost all the materials used in highway engineering are closely related to the mixing station.
