Document Type and Number:
WIPO Patent Application WO/2017/071306
Kind Code:
A1
Abstract:
Disclosed is a modularized fuel oil conveying device for a railway vehicle, comprising a support (15). A first electric oil pump (1), a second electric oil pump (2), a first fuel oil coarse filter (4), a second fuel oil coarse filter (5), a manual rocker pump (3) and a magnetic filter (6) are fixed to the support (15). An upper oil tank oil supply interface (9) and an upper oil tank oil inflow interface (10) are arranged at the upper part of the support (15). A unit oil supply interface (11), a lower oil tank oil inflow interface (12) and a lower oil tank oil supply interface (13) are arranged at the lower part of the support (15). Oil conveying ends of the first and second electric oil pumps (1, 2) and the manual rocker pump (3) are connected to the upper oil tank oil inflow interface (10) via valves. Oil inflow ends of the manual rocker pump (3) and the first electric oil pump (1) are connected to the lower oil tank oil supply interface (13) via the first fuel oil coarse filter (4). An oil inflow end of the second electric oil pump (2) is connected to the lower oil tank oil supply interface (13) via the second fuel oil coarse filter (5). An oil outlet of the magnetic filter (6) is connected to the unit oil supply interface (11). An oil inlet of the magnetic filter (6) is connected to the upper oil tank oil supply interface (9) and the lower oil tank oil inflow interface (12) via an oil supply valve (7) and an oil drain valve (8), respectively. The fuel oil conveying device can be mounted to different types of vehicles, improving vehicle modularity and vehicle production efficiency.
