Detailed Description
Special equipment embodiment:
the special equipment power accessory system comprises an engine and a double-oil-tank oil supply system. The double-oil-tank oil supply system is arranged on two sides of the rear part of the engine, so that the length and installation complexity of oil pipes of the oil supply system are reduced, the power accessory system and the oil supply system are both arranged in the engine cabin body and are sealed, the hardness of external factors to the power accessory system and the oil supply system of the special equipment is reduced, and the situation that the special equipment cannot escape after losing power is avoided. The working principle of the fuel supply system for the engine is shown in figure 1, and the double-fuel-tank fuel supply system comprises a 1# fuel tank, a 2# fuel tank, a first electric control valve, a second electric control valve, a third electric control valve, a fourth electric control valve, a fifth electric control valve, a first three-way joint and a second three-way joint.
The No. 1 fuel tank is connected to the first end of the first three-way joint through a first oil outlet pipeline, and a second electric control valve is arranged on the first oil outlet pipeline; the No. 2 fuel tank is connected to the second end of the first three-way joint through a second oil outlet pipeline, and a third electric control valve is arranged on the second oil outlet pipeline; and the third end of the first three-way joint is connected to an oil inlet of the engine through a corresponding pipeline.
The 1# fuel tank is connected to the first end of the second three-way pipe joint through a first oil return pipeline, and a fourth electric control valve is arranged on the first oil return pipeline; the No. 2 fuel tank is connected to the second end of the second three-way joint through a second oil return pipeline, and a fifth electric control valve is arranged on the second oil return pipeline; and the third end of the second three-way pipe joint is connected to an oil outlet of the engine through a corresponding pipeline.
A connecting pipeline is arranged between the 1# fuel tank and the 2# fuel tank, and a first electric control valve is arranged on the connecting pipeline.
The whole double-oil-tank oil supply system is installed in the closed space of the special equipment and is not easy to operate manually, and all electric control valves in the double-oil-tank oil supply system are switched on and off through remote control of a cab, so that abnormal oil tank oil supply can be cut off remotely under the condition that the special equipment is not stopped.
The special equipment power accessory system with the structure can enable the two oil tanks to work in three working modes of series connection, parallel connection and independence. The working principle of the entire special equipment power accessory system is explained below.
1. And (4) a parallel operation mode.
When the two fuel tanks and the oil outlet pipeline and the oil return pipeline of the two fuel tanks have no faults (no leakage), the first electric control valve is closed and the other electric control valves are opened through remote control of a cab, at the moment, the engine generates pressure to absorb oil from the 1# fuel tank and the 2# fuel tank through the oil pumping function of the engine, the fuel oil in the 1# fuel tank sequentially enters the engine through the second electric control valve, the first three-way joint and the oil inlet of the engine, the fuel oil in the 2# fuel tank sequentially enters the engine through the third electric control valve, the first three-way joint and the oil inlet of the engine to provide power fuel for the engine, the redundant fuel oil sequentially returns to the 1# fuel tank through the oil outlet of the engine, the second three-way joint and the fourth electric control valve on one hand, and returns to the 2# fuel tank through the oil outlet of the engine, the second three-way joint and the fifth electric control valve on the other hand, and fuel circulation is realized.
2. A stand-alone mode of operation.
When a fault (leakage) occurs in the oil outlet pipeline or the oil return pipeline of one fuel tank or one fuel tank, the fuel tank with the fault and the first electric control valve are closed, and the other fuel tank without the fault in the oil outlet pipeline and the oil return pipeline is controlled to provide power fuel. For example, under the condition that a 1# fuel tank or a first oil outlet pipeline corresponding to the 1# fuel tank fails and other pipelines are normal, a cab is used for remotely controlling and closing a first electric control valve, a second electric control valve and a fourth electric control valve, opening a third electric control valve and a fifth electric control valve, closing the 1# fuel tank, enabling the engine to pump oil through the self-oil pumping function to generate pressure to absorb oil from the 2# fuel tank, enabling fuel oil in the 2# fuel tank to sequentially pass through the third electric control valve, a first three-way joint and an oil inlet of the engine to enter the engine, providing power fuel for the engine, and enabling redundant fuel oil to sequentially pass through an oil outlet of the engine, the second three-way joint and the fifth electric control valve to return to the 2# fuel tank, so that fuel oil circulation is achieved. If the second oil outlet pipeline or the second oil return pipeline corresponding to the 2# fuel tank fails and the rest pipelines are normal, the process is similar, and the description is omitted here.
3. A series operating mode.
When the oil outlet pipeline or the oil return pipeline of one fuel tank has a fault (leakage) but the fuel tank has no fault, the fuel tank is not closed at the moment. For example, under the condition that a first oil outlet pipeline corresponding to the No. 1 fuel tank is in fault and other pipelines are normal, the second electric control valve and the fourth electric control valve are closed through remote control of a cab, the first electric control valve, the third electric control valve and the fifth electric control valve are opened, at the moment, the engine generates pressure to absorb oil from the No. 2 fuel tank through the oil pumping function of the engine, the fuel oil in the No. 2 fuel tank sequentially enters the engine through the third electric control valve, the first three-way joint and an oil inlet of the engine to provide power fuel for the engine, the redundant fuel oil returns to the No. 2 fuel tank through the oil outlet of the engine, the second three-way joint and the fifth electric control valve, meanwhile, the oil in the No. 1 fuel tank also enters the No. 2 fuel tank through the first electric control valve, so that the two fuel tanks work in series is realized, the fuel oil of the two fuel tanks is independently absorbed by the No. 2 fuel tank to supply the engine, so that special equipment can normally run.
In a whole view, the arrangement of the two fuel tanks and the corresponding pipeline connection can ensure that the two fuel tanks work in various working modes, so that the special equipment adopting the power accessory system can still meet the running function of the special equipment under the condition that a single fuel tank system is abnormal, the special equipment can run out of a battlefield even if the single fuel tank system is damaged in the battlefield environment, and the anti-strike capability of the special equipment on the battlefield is greatly improved.
In this embodiment, the control valves in the dual-tank oil supply system are all electric control valves. As other embodiments, these control valves may also be pilot operated valves.
