Test systems and processes for equipment vis-a-vis contaminated fuel
View Patent ↗A test system for equipment using fuel, including a closed supply circuit of the equipment configured to supply contaminated fuel to the equipment is provided. The circuit includes at least one tank including fuel, and a pollution module including on or more vats including fuel contaminated by solid contaminants. The module is configured to introduce contaminated fuel to a section of the supply circuit in which the fuel extracted from the tank circulates towards the equipment. The module also includes an agitating tool configured to take contaminated fuel from the vat and return it to the vat, so as to agitate the contaminated fuel in the vat.
1. A test system for equipment using fuel, comprising:
a closed supply circuit of the equipment, configured to supply contaminated fuel to the equipment, said circuit comprising:
at least one tank comprising fuel, and
a pollution module, comprising
a vat comprising fuel contaminated by solid contaminants, the vat comprising top and a bottom,
said module being configured to introduce contaminated fuel to a section of the supply circuit in which the fuel extracted from the tank circulates towards the equipment, and
an agitating tool configured to take contaminated fuel from the vat and return the contaminated fuel to the vat to hydraulically agitate the contaminated fuel, in the vat,
the agitating tool comprising a deflector arranged in the vat, said deflector having a cavity oriented to the top of the vat,
the agitating tool being configured to take contaminated fuel from the vat and to return the contaminated fuel in the direction of the deflector so as to cause ascending agitation motion of the contaminated fuel.
2. The test system according to claim 1 , wherein the vat comprises a conical base.
3. The test system according to claim 1 , wherein the pollution module comprises at least one peristaltic pump configured to:
take contaminated fuel from the vat, and
send the contaminated fuel to a section of the supply circuit in which the fuel extracted from the vat circulates towards the equipment.
4. The test system according to claim 1 , further comprising a parallel circuit configured to ensure non-zero circulation flow of fuel in the supply circuit, said parallel circuit being connected to the supply circuit upstream of the equipment and to the supply circuit downstream of the equipment.
5. The test system according to claim 1 , wherein the supply circuit comprises at least one conduit made of flexible material.
6. The test according to claim 1 , wherein the pollution module comprises:
a plurality of vats, and
a control unit, configured to control the pollution module so as to introduce contaminated fuel to a section of the supply circuit in which the fuel extracted from the tank circulates towards the equipment from one or more of the vats.
7. The test system according to claim 1 , further comprising a Pitot tube, arranged in the direction of circulation of the fuel, in a section of the supply circuit located between the vat and a circulation pump of the supply circuit.
8. The test system according to claim 1 , further comprising a filling connection between the vat and the tank for filling of the vat with fuel contained in the tank.
