  From the data released by the European Asphalt Pavement Association, the methods of asphalt pavement regeneration in Europe and America are mainly heat and temperature mixing, and the international Organization for Economic Cooperation and Development (OECD) survey on the recycling of pavement in 14 countries shows that (asphalt part), Hot mix regeneration (plant mixing heat regeneration) is a commonly used regeneration method, cold regeneration generally only accounts Other regeneration methods are also used in only a few countries.

The main problems that may arise include: 1, can not be commutative or the commutative action is slow, 2, the valve core seal ring damage is serious, 3, the pilot solenoid valve stomata is blocked, can not be commutative and so on.

In response to these problems, we not only need to carry out regular inspections, but also to maintain a good degree of cleanliness.

In addition, damaged parts should be replaced in a timely manner to reduce the probability of problems occurring.

In the work of asphalt mixing station, it will be affected by many factors.

And in order to ensure the quality of the work, we need to fully analyze these influencing factors.

Among the many influencing factors, there is a class of influencing factors that can be divided into human factors, the following we will be in response to this factor to help you analyze, I hope to be able to help.

After multiparty consultation and market research, at present, China has very few burner manufacturers can produce gas burners, but not the asphalt mixer burner has been modified, and the technology is very immature, can not be connected with the mixer automatic control system, to achieve automatic temperature control, there are safety risks, so domestic burners do not consider.

Imported asphalt mixer Burner technology mature, safe and stable, China has been transformed a number of, and is currently using good.

Imported burners are mainly the United States Howe and the Italian general two brands, the United States Hao Ke has simple operation, high degree of automation, good security, a wide range of fuel and other advantages, but the price is more expensive, oil, gas dual-use burner transformation Total price of 750,000 yuan, gas burner also need 600,000 yuan.

  2. Cold regeneration  Cold regeneration refers to the asphalt pavement in the process of regeneration of old materials do not need to heat the old materials, according to the requirements of the restoration of the performance of the old material emulsified asphalt and other additives, and then carry out other cold regeneration process.

  (1) The commutator valve can not be commutative or commutative action is slow, generally due to poor lubrication, spring is jammed or damaged, oil or impurities stuck in the sliding part and other reasons caused.

In this regard, you should first check whether the oil mist is working properly, the viscosity of the lubricant is appropriate.

If necessary, replace the lubricating oil, clean the sliding part of the commutator valve, or replace the spring and commutator valve.

In addition, the technical level of operators of different types of workers.

Every job is very important and indispensable.

As the host operator of asphalt mixing station, it is necessary to have a strong sense of responsibility and professional quality, skilled operation of equipment, in the course of work, have a strong judgment and adaptability.

And can be under the guidance of technical personnel, timely elimination of some security risks and other issues.

The third is the possible failure of the cylinder in the asphalt mixing station.

The main problems that may arise include: 1, internal and external leakage of cylinders, 2, insufficient output force and uneven movement, 3, poor cushioning effect, 4, piston rod and cylinder head damage and so on are included.

For these problems, for reasons that vary, we need to identify the causes and take targeted measures to deal with them.

Geothermal regeneration.

  Geothermal regeneration technology was once considered a revolution in the road industry; However, later practice has proved that there are many limitations in the field thermal regeneration: small treatment thickness, can not effectively adjust the mix ratio of recycled mixture, mainly used for surface regeneration, the road surface thickness is not uniform or the quality of the road surface changes are difficult to ensure quality requirements.

In China's asphalt pavement diseases, mainly water damage, cracks and other structural damage, surface treatment is difficult to solve these problems, so geothermal regeneration equipment should not be popularized in China.

  The fault of the oil mist device is: The adjustment of the adjustment needle is too small oil road blockage, pipe leakage and so on will make the liquid oil droplets can not be atomized.

In this regard, the blockage and leakage of the place should be dealt with in a timely manner, adjust the amount of oil dripping, so that it reached about 5 drops of/min.

When used normally, the oil surface in the oil asphalt mixing cup should be kept within the upper and lower limits.

Moisture deposited at the bottom of the oil cup should be removed in time.
