5) When excessive impurities are accumulated at the bottom of the fuel tank (20) and need to be cleaned after the generator set (10) operates for a long time, starting self-circulation filtering operation;
the self-circulation filtering working steps are as follows: the working personnel operate the power generation vehicle controller to send out a cleaning signal, the oil drain valve (21), the oil supplementing valve (26) and the first ball valve (23) are opened, the first oil supply pump (24) is powered on, fuel in the fuel tank (20) is pumped out through the oil drain valve (21), and the fuel enters the fuel tank (20) through the oil filter (22), the first ball valve (23), the first oil supply pump (24), the second flowmeter (25) and the oil supplementing valve (26), so that a self-circulation filtering function is realized; when the cleaning is required to be stopped, the electric power generation vehicle controller is operated to send a cleaning stopping signal to close the oil drain valve (21), the oil supplementing valve (26) and the first ball valve (23), and the first oil supply pump (24) is in power failure to stop supplying oil to the fuel tank (20);
6) When the power generation vehicle is in emergency rescue and disaster relief, the road condition is complex, the oil tank truck and the oil storage equipment cannot arrive in time, and when the auxiliary vehicle or other equipment lacks oil, the oil is discharged outwards;
the outward oil discharge working steps are as follows: the external oil drain valve (32) is communicated with an oil inlet of the oil storage device (30), the electric generator controller is operated to send out an oil drain signal, the oil drain valve (21) and the external oil drain valve (32) are opened, the first oil supply pump (24) is powered on, and fuel in the fuel tank (20) is pumped out through the oil filter (22), the first ball valve (23), the first oil supply pump (24) and the second flowmeter (25), so that oil is drained to the oil storage device (30), and an outward oil drain function is realized; when the oil discharge is required to be stopped, the electric power generation vehicle controller is operated to send out an oil discharge stopping signal, the oil discharge valve (21) and the external oil discharge valve (32) are closed, the first oil supply pump (24) is in power failure, the internal combustion oil in the fuel tank (20) is stopped to be pumped out, and the outward oil discharge is closed;
7) When excessive impurities are accumulated at the bottom of the oil storage device (30) and need to be cleaned, the external circulation filtering work is started; the external circulation filtering operation comprises the following steps: the external oil supply valve (31) and the external oil drain valve (32) are simultaneously connected with the oil storage device (30), the electric generator controller is operated to send out an external circulation signal, the external oil supply valve (31) and the external oil drain valve (32) are opened, fuel oil in the oil storage device (30) is pumped out through the oil filter (22), the first ball valve (23), the first oil supply pump (24) and the second flowmeter (25), and enters the oil storage device (30) through the external oil drain valve (32), so that an external circulation function is realized; when the fuel tank needs to be closed, the power generation vehicle controller is operated to send out an external circulation closing signal, the external fuel supply valve (31) and the external fuel discharge valve (32) are closed, the first fuel supply pump (24) is powered off, the fuel in the fuel storage device (30) is stopped to be pumped out, and the external circulation is closed;
8) In the actual use process, when the first oil supply pump (24) or the first ball valve (23) fails, the second flowmeter (25) monitors the running flow of the pipeline system and feeds back a low oil or oil shortage signal to the generator car controller, and the generator car controller starts standby uninterrupted operation; the steps of spare uninterrupted operation are as follows: the power generation vehicle controller starts the second ball valve (27) and the second oil supply pump (28) to ensure the normal operation of the pipeline.
