MI-GM0701 - Hydraulic of industrial systems

Fields of applications: auto manufacturing, aeronautics, mining, aluminum industry, pulp and paper, plastic industry, steel factories, …etc.

Industrial systems mean all fixed machines installed in a transforming or manufacturing products factory. They allow setting up very important powers in a specific sequence such as in a production chain: every function complies following the preceding one, until the complete cycle of task is effected. This seminar describing the active components in a hydraulic system will allow you to get a well understanding of their functional principle and prevent the possible failures which could be generated.

MI-GM0802 - Hydraulic of mobile systems

Fields of applications: naval, aeronautics, snow moving equipment, lifting machines, spreader, dump trucks, military equipments, ...etc

The mobile systems are defined as machines or materials which perform their function while being in movement. In the contrary of hydraulic systems, they allow to carry out often several operations simultaneously. The valves which are already installed are therefore conceived to obtain this flexibility. This seminar presents the functioning principle of valves used in the mobile applications, as well as characteristics of the energy savings relating to these machines.

MI-GEM0803 - Electrohydraulic systems

Fields of applications: industrial and mobile hydraulic systems with proportional valves and servo valves.

In most of industrial applications it is requested to transmit a hydraulic power, but it is presently requested more often to control it and regulate it. This implies that new components, of which the proportional directional valves, the pressure proportional valves and servovalves, appeared and took an important place: this is electrohydraulic. The use of these components requires a large and more and more deepened knowledge of their functioning: we present them to you through this seminar.

MI-GEM0804 - Control of Electrohydraulic systems

Fields of applications: industrial and mobile hydraulic systems with electronic cards and position, speed and force sensors.

A controlled system (close loop system), is a system which the result is directly releated to the command that sent to him. Thus, the system reaction is entirely done in advance, in verifying the different internal or external factors that could affect it. It follows that the servovalves and the proportional high performance valves are joined to sensors which allow acquiring the data from the permanent status of systems while they are working. Attending to this seminar, you will learn how the features of P.I.D controllers allow controlling efficiently position, speed or force of cylinders and hydraulic motors.

MI-GEM0805 - Preventive maintenance of hydraulic circuits

Fields of applications: industrial and mobile hydraulic systems

Most of machines and modern production are equipped with hydraulic circuits. These circuits have a better performance if their reliability is ensured, as well as their availability and security. Through this seminar, we present to you the maintenance principles based on periodical and conditional maintenance subordinated to the use of pressure gauge, flowmeter, sensors,…etc.

MI-GEM0806 - Corrective methodology of hydraulic circuits

Fields of applications: industrial and mobile hydraulic systems

Which one do you prefer? Mr. error-test or Mr. Methodic? Mr. error-test is the one working on the breakdown, replaces the parts until he maybe finds the failure, after having lost time and money. Whereas Mr. Methodic thinks first about the problem, determines all factors and analyzes them until he finds exactly and precisely the default. Next, he verifies the diagnostic by a control and then replaces the parts. Due to the complexity and dangers inherent to hydraulic systems; the research and control method used by Mr. Methodic is the only one valid. Would you like to know it? This seminar will give you a favorable answer.

MI-GM0807 - Properties and selection of hydraulic fluids

Fields of applications: industrial and mobile hydraulic Systems

Hydraulic fluid is considered as a substance which deforms itself according to its environment and that can elapse without rigidity. The most important physical properties regarding mechanics are the isotropy, mobility (or velocity), viscosity and compressibility. It implies that its role is preponderant in the hydraulic systems functioning, because it serves mainly to transmit the power. The choice of fluid to be used for your systems must be made in considering the features of the type of hydraulic pumps and its manufacturer, the temperature of operating, as well as the environment (interior or exterior of a factory, season, geography, etc) in which the machine will operate.

MI-GEM0808 - Safety of hydraulic machines

Fields of applications: industrial and mobile hydraulic systems

It's no longer necessary to demonstrate the power of hydraulic machines; it is the most important advantage of this type of energy transmission. However, this feature involves precaution considering the fact that conception, manufacturing, maintenance and troubleshooting are done by individuals. The energy generated or stocked in the pipings and the systems components can be very dangerous for the operators. We present through this seminar, not only the national and international standards that the design engineers must respect, but also the safety measures that all operators need to develop.

MI-GM0809 - Hydraulic circuits Design

Fields of applications: industrial systems

Designing a hydraulic system is a responsibility and difficult task; for this reason it is inserted by engineers act stipulating that this design type can only be made by an engineer who has the competencies, or at least under the direct supervision of a competent engineer. The hydraulic circuits design necessitates an efficient analysis of the specifications, a global vision of all direct and indirect implications during the using of the system to design, precise calculations of the different variables, a well detailed and thorough selection of the components to be used and above all, a best and safe choice of solutions which would allow to respect needs enumerated in the specifications.

MI-GE0910 - Grafcet for hydraulic systems

Fields of applications: industrial and mobile hydraulic systems

The GRAFCET or Sequential Function Chart, is an acronym from French: GRAphe Fonctionnel de Commande Etape Transition and it is a graphical tool for defining an automated sequence. It is also used in many combinatorial cases where there is a sequence to be respected. The basic concepts of this discrete system model are clear and simple: describe the automation with steps associated to actions and transitions.
This seminar is an introduction to the understanding of this clear language, strict and unambiguous, independent of the practical application and the technology used; but presented with cases of hydraulic automatisms to define the necessary steps to design,validate and implement the automated system.

MI-GM0911 - Hydrostatic circuits analysis

Fields of applications: naval, aeronautics, snow moving equipment, lifting machines, spreader, dump trucks, military equipments, ...etc

The hydrostatic transmission circuits, known in some cases as closed hydraulic systems are power transmission systems, designed for applications that require high operating yields with rotating receivers. This type of circuit is usually characterized by the fact that the oil used by the motor comes back directly to the pump without passing through the reservoir. This seminar describes the working principles of different parts of hydrostatic transmissions.

MI-GE0912 - Electricity control of hydraulic systems

Fields of applications: industrial and mobile hydraulic systems

Although a hydraulic system can be controlled through different technologies, for practical reasons, stability and flexibility, the hydraulic valves are usually controlled either electrically or by a combination of electro-hydraulics. When it comes to proportional valves, the signal is so small that it needs to be amplified in order to move the drawer's valves which requires average currents of about 1.6A.
This electric and electronic omnipresence in controlling hydraulic systems requires a basic understanding of electrical principles. Through this seminar and after an overview of the basic principles of electricity, we will analyze the electronic circuits of the amplifying boards which make it possible to generate the stability of given commands.

MI-GEM0913 - Security standards for hydraulic presses

Fields of applications: industrial systems

The industrial hydraulic presses carry out work with high pressure, this characteristic as well as the presence of a slide on these systems, needs special attention concerning security practices and must comply with the installation of security standards dictated by the Organizations for Standardization. Organizations such as the Canadian Standardization Association (CSA), European Committee for Standardization (CEN) and the International Standardization Organization (ISO), amongst other things enacted standards surrounding the systems of hydraulic presses very present in industries of manufacture and transformation. Through this seminar, you will know the most relevant standards which frame the work on the hydraulic presses.
