The rational use and careful maintenance of road construction machinery are two basic points for the use of road construction machinery by our mechanized construction enterprises. To use good road construction machinery, we must first maintain and repair road construction machinery. Conversely, the purpose of maintaining road construction machinery is to make the road construction machinery use well. Therefore, highway mechanization construction enterprises must properly handle the relationship between the two, rational use and careful maintenance, in order to enable road construction machinery to exert greater potential, ensure the quality of highway construction, speed up the construction progress of highway projects, and improve the economic benefits of enterprises.
The asphalt mixing equipment production unit consists of three parts: water heating and blending; drain ratio and emulsification; finished product output. Among them, the drainage ratio and emulsification are the key to the whole machine. In order to solve the ratio of oil to water, two speed-regulating electric gear pumps are adopted. According to the ratio of oil to water, the speed of the gear pump is adjusted to meet the specified ratio, which is intuitive and convenient to operate. The emulsified modified asphalt production core component emulsifier (ie colloid mill) uses a unique three-layer grinding shear structure to maintain a very small stable gap. The specially treated stator and rotor have good wear resistance and corrosion resistance, ensuring emulsification effect and stability.
The emulsion tank equipped with this machine is made of stainless steel and is equipped with PPR material emulsion delivery pipeline, which has strong corrosion resistance. The supporting asphalt pump is a circular arc gear oil pump with stable operation and low noise. High-quality matching electrical components greatly improve the operational stability of the equipment, expand the adaptability of the unit, and extend the service life of the equipment.
Equipped with high-efficiency heat exchanger, the finished emulsified modified asphalt is cooled by heat exchanger to improve its storage stability; the cooling water is heated at the same time, used for emulsified asphalt production, eliminating the heating cost of clean water and reducing the production cost of emulsified asphalt. energy saving.
When assimilated with road construction machinery, it should have excellent compatibility and should not cause condensation or demulsification. It is recommended to use sbs in areas where the temperature is more severe, and sbr in areas where the temperature is more severe. The process of emulsification, mixing and formation is also a process in which the emulsion system is demulsified and the emulsifier is adsorbed by the stone. The purpose of its growth target can be divided into the following several annual savings in material costs. Should be loose and dry, no poly unity block is subject to moisture.
