"S-engineering" has many years of practical experience in the development of power supply systems and automatic process control systems for oil-extraction plants (OEP), port and linear elevators and other industrial enterprises in the food processing industry.

In our solutions, we apply basic and unique functions, advanced foreign manufacturers' technologies and own patented technologies SENUMAC and LEFFOL.

Unique functions in the process automation systems:

The electric drive of power lifting and handling equipment of bulk cargo is designed to launching the process equipment under load, and involves excess capacity at nominal operating conditions. This principle leads to the presence in the processing chain of "weak" points, that with increased power consumption. Thus the technological chain performance is limited by the capacity of the "weak" point. At that the potentially maximum performance of the line is not used.

To solve this problem S-engineering has developed a unique technology LEFFOL. This technology through the creation of mathematical models of each element of production line and their interaction allows to determine mathematically the modes of "weak" points operation with playback of operating characteristics of electric motors for maximum line performance and to extend the equipment operation term.

An important problem of the enterprise, especially for port grain terminals is the direct dependence of production line performance on the experience of process operator. Unscheduled stops of the processing equipment are associated with the occurrence of bucket conveyor obstruction, and are determined by a lack of coordination of technological line elements capacities and the human factor.
To eliminate the influence of the human factor and ensure stable maximum performance of lifting and handling equipment S-engineering has developed a unique technology SENUMAC.
The introduction of this technology allows gaining automatic load control of flow-transport line of bulk materials, and allows achieving the following results:

  • Increasing productivity (up to 20%)
  • Reducing energy consumption (by 20-30%)
  • Minimizing the occurrence of accidents
  • Increasing equipment lifetime
  • Diagnosing and predicting equipment failures
  • Improving the efficiency and failure safety of technological processes

An important problem of grain drying technological process is the low accuracy of grain moisture regulation by measuring devices. The lack of industrial solutions of humidity measurement in the grain flow and special algorithms of humidity control, lead to certain difficulties, which generally make the process uneconomical and fire hazardous requiring closer attention of the process operator.
"S-engineering" has developed solutions that allow:

  • Reducing the consumption of energy for removing moisture from the grain by 5 – 15%;
  • Reducing the loss of marketable grain mass by preventing its overdrying by 0.5 – 1.5%;
  • Reducing the time for drying grain party, which in its turn implies energy savings by 6 – 18%.

The constant growth of the requirements to the quality of the output product requires precision in the control of equipment technological parameters. It is rather difficult to achieve the precision dictated by modern requirements with the standard control methods. The control parameter falling beyond the process regulations entails defective goods, the need for recycling the product back for revision, increasing the time of manufacturing a unit of output, overconsumption of energy resources.

Complying with the process regulations, minimizing the number of defective goods, improving energy efficiency of production will be possible due to the special control algorithms designed by our experts. We offer control algorithms with high dynamic accuracy, ensuring and optimization.

The controller parameters are calculated for each controlled object individually and optimized on a mathematical model of the controlled object by our specialists. As a result, the customer receives a working regulator that requires no additional adjustment on the site.

"S-engineering" has successfully implemented such solutions algorithms for hammer crushers, presses-granulators, presses-extruders, multi-component dosing units, dryers, pasteurizers.

Modern solutions of basic functions in the processes automation systems

The industrial processes automation system must clearly carry out the tasks assigned to it - the basic functions, without which no automation system can exist. The method for implementing these functions affects directly the performance optimality, efficiency, reliability of the system.

"S-engineering" offers the realization of the basic functions with modern methods meeting the high demands of the technological process and the scientific-technical progress.

application of distributed I/O systems for gathering information from the process equipment can significantly reduce cabling and wiring products costs and cable support systems, their installation, which in its turn leads to the reduction of the budget for the construction of the facility and the deadlines.

 

function of automatic route planning with the choice of only 2 endpoints (start and end), eliminates mixing products during their transportation, product loading and unloading. Such a principle of route planning eliminates the error of the process operator.

 

Integration of the automation system with enterprise management software systems (1C) allows building a single management system with centralized control and management of all the inbound and outbound flows.

function of remote access to the automation system allows the developer to quickly analyze the causes and problems in the system, give recommendations, indicating corrective actions to the maintenance staff, ensuring minimized downtime of the process equipment without the system developer's arriving to the facility for maintenance.

application of standard libraries, honed over many years, allows shortening the time of writing software, reducing the object launching time.

  • function of hours in service;
  • control of important parameters of the equipment, signaling of the need for maintenance/repair;
  • recommendations on the action plan for replacement/repair of the faulty equipment allow optimizing the servicing of the process, thereby reducing the service costs.

The functions of "Grain Board", "tips with action options" do not just simplify to the maximum the work of the process operator, but also eliminate mechanical errors in the management of elevator/grain terminal.

implementation of algorithms for road and rail scales allows not only applying the advanced developments in weighing, but also fully integrating scales in the technological processes automation system and enterprise management software systems (1C).

implementation of algorithms of the hopper scales allows not only making precise and fast weighing, providing high-performance of the processing equipment, but also fully integrating scales in the technological processes automation system and enterprise management software systems (1C).

the optimal control of the preparatory room performance of oil extraction plant performance is ensured by maintaining the maximum-achievable performance of the room; prevention of the occurrence and development of all possible accidents, in particular an imbalance of the performance of series-connected processing units groups; load balancing between parallely working expellers in case of reduction of the seed kernel feed for pressing.

wireless networks allow controlling mobile units, such as ship-loader, decentralized system of valves on the pipeline. This solution allows making connection with remote mechanisms, which can not be achieved through other wired solutions.

The application of electric control equipment, assembled by the technology SIVACON S8 and SIMOPRIME which have been tested and confirmed by the certificates, provides security for staff due to the accident localization in the compartment in which the accident occurred.
