Practice 1: Identification of the elements of machines of fluid in assemblings CAD. Aims and development:
In this first practical session the student goes to open media files (images, videos, CAD files) prepared by the professor to visualise the constitutive elements of hydraulic installations and machines of fluids.
The main aim of this practical is to strengthen the nomenclature and facilitate the three-dimensional visualisation of the flow in the interior of the machines of fluid.
Practice 2: Mentored work (TT). Bank of positive displacement pumps Aims and development:
The aim of this second practical session is the visualisation of the different positive displacement pumps by means of the available multimedia content to the effect. It treats to characterise and comprise the operation of these pumps, looking for the understanding of his characteristics and possible applications.
Indeed, it supposes the start of the mentored work.
Practice 3: Simulation of oleohydraulic circuits with demostrative software FluidSim Aims and development:
To strengthen the theoretical knowledges of the subject 4, in this practice will design a simple hydraulic circuit, with the aim to comprise the activities of each one of the elements involved: elements of generation, of performance and of control. It uses the software Fluidsim (hydraulic version, previusly instaled in portable teams), with the last updates. It delivers to the student presentation of introduction, example guided and problem proposed.
Practice 4: Simulation of pneumatic circuits with demostrative software FluidSim. Aims and development:
To strengthen the theoretical knowledges of the subject 5 pretends that the student design a pneumatic circuit of intermediate complexity to satisfy some requirements imposed by the professor, analyse the operation of the different elements and research of the greater simplicity of the circuit. It uses the software Fluidsim (pneumatic version, previusly instaled in portable teams), with the last updates. It delivers to the student presentation of introduction, example guided and problem proposed.
Practice 5: Mentored work (TT) Aims and development:
Realisation of the mentored work.
Practice 6: Mentored work (TT). Calculation of a real hydraulic installation by means of the software Epanet Aims and development:
In this practice model is created and problems of installations of real pumping with the software Epanet (previusly installed in portable computers) are resolved. This practice aims to convey the importance of using the sofware, although the user needs the knowledges of necessary engineering for the correct introduction of the data and interpretation of the results. It delivers to the student presentation of introduction, example guided and real case proposed.
This content will be implemented in the mentored work.
Practice 7: Mentored work (TT) Aims and development:
Realisation of the mentored work.
