Abstract

PURPOSE:To prevent damage of the bearing portion of a prime mover by connecting a fuel passage to a lubricating oil supply passage by means of a pressure generating means, and also by providing a control means which controls operation of respective pumps and a stop valve. CONSTITUTION:A pressure generating means 31 has a flexible partition 32 and a vessel 33 which contains the partition 32. The vessel 33 is communicated with a fuel passage 21, and the inside of the partition 32 is communicated with a lubricating oil passage 22. A control device 51 controls operation of respective pumps 7, 13 and a stop valve 12. When prime movers 1 and 3 are going to start, pressure of the lubricating oil contained in the partition 32 is increased through the partition 32 owing to the pressure of the fuel entering the vessel 33. This pressurized lubricating oil is discharged to the lubricating oil supply passage 22. Thus, it is possible to supply adequate quantity of the lubricating oil to the bearing portion of the prime movers, and also to prevent damage on the bearing portion.

In gas turbine engines, when the engine is stopped, lubricating oil is also transferred to the bearing box 1.
Since the inside of the engine is also at a high temperature, the lubricating oil flows down from the bearing, and the next time the engine is started, only a small amount of lubricating oil remains on the bearing. For this reason, if only a small amount of lubricating oil is supplied during startup, the bearing (shaft 4
damage to the exposed part). In particular, in gas turbine engines that use ball bearings as bearings and often supply lubricating oil to these by jet lubrication, a small amount of lubricating oil prevents the jet itself from reaching the ball bearings, resulting in full thermal lubrication. The damage is likely to be severe because the condition is close to that of the original one.

That is, FIG. 3 shows the operation sequence executed by the control device 58, and as shown in FIG. be satisfied. When starting the engine, first, before turning on the starter, the fuel pump motor 8 and the lubricating pump motor 14 are energized with the fuel system stop valve 12 closed. At this time, since the stop valve 12 is closed, the fuel system rises to the maximum pressure specified by the differential pressure regulating valve 9. On the other hand, the viscosity of fuel does not become extremely high even in cold weather, unlike lubricating oil, so pressure builds up quickly.

In a gas turbine engine, the maximum pressure in the fuel system is sufficiently higher than that of the lubricating oil, so this fuel pressure causes the bellows 41 to contract, causing the lubricating oil inside the bellows 41 to rapidly leak outside. The lubricating oil is pushed out from the lubricating oil introducing passage 35 to the lubricating oil introducing passage 22, and passes through the bearing box 18.
Supplied on the side. As a result, a certain amount of lubricating oil is supplied to the bearing portion in advance before starting. Next, as shown in FIG. 3, the starter for starting the gas turbine engine is turned on to start the engine. And when the engine starts,
After a predetermined period of time has elapsed, the stop valve 2 is opened and fuel supply to the combustor 2 is started.

On the other hand, when stopping, as shown in the timing chart of FIG. 3, the fuel pump 7 is stopped at the same time as the stop valve 12 is closed, and then the lubrication pump 13 is turned on for a while.
It cools the bearing box 18 and assists in filling the bellows 41 with lubricating oil. This allows the second
The bellows 41 is sufficiently filled with lubricating oil through the lubricating oil introduction passage 35 as shown by the arrow in FIG. 3(C). At this time, the fuel in the container 33 passes through the gap in the fuel pump 7 and returns to the fuel tank 10.

In this way, in this embodiment, a certain amount of lubricating oil is first supplied to the bearing section at the initial stage of startup, and the shaft 4 rotates for a while without causing damage due to the lubricating oil, during which time the starter is turned on. This allows each motor 8.
By increasing the voltage supplied to the engine 14 and by increasing the amount of lubricating oil as the lubricating oil warms up due to heat generation in each part, sufficient lubricating oil is supplied and safe continuous operation can be started.
