“…Large international enterprises mainly include Atlas Copco, Sandvik, etc. [11]. Due to the short R&D period in China and the strict confidentiality of design and control technology by foreign companies, the emulsion pump station developed in China lags far behind foreign countries in terms of promotion and application.…”

No matter in metal mines or coal mines, an emulsion pump station has a wide range of application market and can play an important role. In this paper, the frequency conversion constant pressure control system of the mine emulsion pump station is taken as the research object. The two kinds of water-based drawing fluids used are dispersed drawing fluid and emulsion drawing fluid. After the intelligent level of the equipment reaches a very high level, an environmentally friendly, safe, and efficient Internet of Things technology system will be added. Combined with 3D laser scanning technology based on self-scanning of road contours, the blast method is input to the terminals of the emulsion pump station for automatic blast hole positioning and semiautomation of the emulsion pump station. Combined with 5 g communication and other intelligent key technologies, it realizes high-end functions such as fault self-diagnosis, remote operation, and remote monitoring of the emulsion pump station and rock drill, which can be called full intelligent stage. The results show that the initial friction coefficient of drawing fluid A lubrication is 0.21, and then, with the extension of time, the friction coefficient gradually decreases to 0.14. The initial friction coefficient of drawing fluid B is 0.22, then it decreases rapidly to 0.13, then it is stable at 0.17, and then it remains basically unchanged. When the temperature is 55°C, the initial friction coefficient is 0.16 and then decreases to 0.12. Therefore, the frequency conversion constant pressure control system of the mine emulsion pump station should be selected according to the environment and application scenarios.

“…The main purpose of the parallel-flow drying drum is to obtain a finished product with a moisture content of 0.4 -0.5 %. To maintain the stability of the technological process, it is necessary to control it, taking into account the mutual influence of temperatures in the furnace, in the mixing chamber and in the drum itself [2, 12,13,14]. In cases where temperature control in the furnace does not allow maintaining optimal humidity, at low humidity, the temperature in the mixing chamber should be adjusted by increasing the supply of secondary air, and in a situation where the humidity is high, the number of revolutions in the drying drum should be reduced.…”

The process of removing liquid from the surface or inner layers of materials is widely used by various enterprises. To implement such a process, such a method of dehydration as drying is most often used. In drying technology, drum dryers are the most common type. Controlling a drum dryer causes problems such as low efficiency (0.4-0.6) and high operating costs. To eliminate these problems, it is proposed to develop a system of adaptive fuzzy control of a continuous-flow drum dryer in order to increase the efficiency of control of technological processes of drying sand by using intelligent technologies. The method for this article is adaptive control using fuzzy logic control, which has the ability to control the parameters of the dryer depending on changes in the parameters of the control object or external disturbances acting on the control object. Adaptive fuzzy controllers are created on the basis of the proposed method. A model of the control object has been developed taking into account the links between the parameters of the technological regime. The processing of the research results was carried out using the MatLab software. The practical significance of the article lies in the fact that the results can be used in enterprises where parallel-flow drying drums are used to obtain a product of the highest quality, as well as to reduce the cost of purchasing raw materials.

We have developed control system for a fermentation unit process based on a fuzzy controller. The objects under control are fermentation tanks located at “Bashspirt” Joint-Stock Company. The process of saccharifiedwort fermentation is carried out by yeast. The task was to improve the process of fermentation of saccharifiedwort by yeast and replace the outdated control system with a newer and more modern one. In this regard, a fuzzy controller system has been designed to control the process of fermentation unit capable of controlling the following twelve output parameters: valve position for supplying wort to six fermentation tanks and for supplying yeast to six fermentation tanks. Twelve control output parameters control the following seven input parameters: the fill level of the prefermenter, the fill level of six fermentation tanks. The output parameters are controlled on the base of the information obtained from the wort and yeast input level sensors. The introduction of an automatic control system that takes into account the basic parameters of a multi-connected object and is capable of controlling the entire process of the fermentation unit allowed to solve the following problem: stabilization of the input parameters and the output process parameters control.
