As shown in fig. 2, a ground effect craft fuel starting system includes: left oil tank and right oil tank, left engine and right engine and supplementary oil pump, the starting system includes:
the pre-starting pipeline consists of a right oil tank, a first oil discharge switch, an auxiliary oil pump, a first one-way valve and an oil conveying pipeline, wherein the allowed flow direction of the first one-way valve is that the right oil tank flows to the auxiliary oil pump, and fuel oil in the right oil tank is output through the auxiliary oil pump and the one-way valve to be pre-started;
the left engine starting pipeline consists of a left oil tank, a second oil drain switch, a third one-way valve, an oil filter, a second cut-off switch and a left engine, wherein the allowed circulation direction of the third one-way valve is that the fuel oil flows from the left oil tank to the left engine, and the fuel oil in the left oil tank supplies the fuel oil to the left engine through the left engine starting pipeline;

and a cross switch installed between the first cut-off switch and the second cut-off switch for switching the direction of the fuel flow to the left engine or the right engine.
A first oil-gas return one-way valve is connected between the right engine and the right oil tank to return oil gas to the right oil tank.
And a second oil-gas return one-way valve is connected between the left engine and the left oil tank to return oil gas to the left oil tank.
The working process of the utility model is as follows:
when the engine is started in advance, the auxiliary oil pump is started, a certain amount of fuel oil is pumped from the oil tank, so that the two engines have starting conditions, and the rear auxiliary oil pump is closed.
When the left engine is started, the left oil tank supplies oil through a left engine starting pipeline, the cross switch is switched on, the second cut-off switch is switched on, and the first cut-off switch is switched off; after the left engine is started, the cross switch is switched off, the first switch is switched off, and the right engine is started through the right engine starting pipeline.
After the two engines are started, the cross switch is switched off, and the oil supply ways of the left engine and the right engine are as follows:
a. the left oil tank transfers oil to the left engine to work normally, and each working state of the engine is finished.
b. The right oil tank transfers oil to the right engine to normally work, and each working state of the engine is completed, which is a normal oil supply state.
If the right oil tank has oil transportation fault and can not normally transport oil to the right engine, the oil transportation route is changed, the cross switch is opened, and the oil path transports the oil from the left oil tank to the right engine through the second oil drainage switch, the third one-way valve and the first cut-off switch.
Similarly, if the left oil tank has oil delivery fault and can not deliver oil to the left engine, the cross switch is turned on, and the oil delivery line supplies oil to the left engine through the second cut-off switch, so that various working states of the engine are met.
The left oil tank and the right oil tank can independently supply oil for the left engine and the right engine, and can also simultaneously supply oil for the left engine and the right engine through the cross switch, so that the normal work of the engines cannot be influenced due to the fault of a unilateral fuel oil system, and the engine test proves that 2 engines can normally work.
The existing fuel oil starting system is arranged at the rear section of a passenger cabin, and according to the requirements of the ground effect wing ship inspection guide on the design of a wing ship: the fuel system should be separated from the passenger cabin.
The fuel starting system is not separated from the passenger cabin and has a great risk to the environment and the safety of passengers in the passenger cabin.
In this embodiment, the starting system is mounted on the rear of the inner wing of the WIG craft.
In the prior art, the installation position of the auxiliary oil pump is incorrect, the installation position of the auxiliary oil pump is higher than the fuel oil level line of the fuel tank, and the problem that the auxiliary oil pump cannot suck oil during idle stroke operation is easily caused when an engine is started. The idle stroke working time of the auxiliary oil pump is not allowed to exceed 90 seconds, and the auxiliary oil pump is easily damaged if the idle stroke working time exceeds the time.
And, the motor of the auxiliary oil pump and the fuel pump are horizontally installed, which is a great risk. The correct mounting mode is that the motor is arranged below the fuel pump, so that the condition that the motor catches fire due to oil leakage of the fuel pump can be avoided.
In this embodiment, the installation height of the auxiliary oil pump is higher than the installation height of the fuel pumps of the left and right engines. The installation position of the auxiliary oil pump is lower than the installation positions of the left oil tank and the right oil tank.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
