Definitions
- the present invention relates to a supply system for coolants and / or lubricants, in particular for transmissions and generators.
- Gearboxes are among the most heavily loaded components of large-scale systems, especially wind turbines. They have to withstand enormous torques, vibrations and climatic conditions. At the same time, the efficiency of the transmission should be as high as possible.
- the demands on the attachments of the gearbox increase.
- these include, but are not limited to, the supply systems e.g. for cooling and / or lubricants. They ensure the lubrication of bearings and gears of the gearbox.
- the lubrication system thus reduces wear and friction and increases the life and load capacity of the components of the transmission.
- WO 2009/147147 now discloses a lubrication system for transmissions in which, in addition to a lubricant tank for supplying a pump for dry sump lubrication of the transmission, there is provided a second lubricant tank in which an increased pressure prevails.
- the pump can no longer supply the transmission with lubricant from the first lubricant tank.
- the changing pressure conditions in the lubricant lines are measured and a valve between the second lubricant tank and the transmission opens. Due to the increased pressure in the second lubricant tank lubricant is pressed into the gear, which is wet-lubricated in this way and takes no damage.
- the second lubricant tank geodetically higher than the transmission and supply the gear in emergency operation by the hydrostatic pressure with lubricant.
- the disadvantage here is the need to provide additional space for a second lubricant tank.
- WO 201 1/048183 moreover discloses a lubrication system for transmissions, in which a lubricant tank is connected to a vacuum pump. This vacuum pump ensures that the pressure in the lubricant tank during normal operation is lower than in the gearbox, so that the lubricant flows from the gearbox into the lubricant tank and a dry sump lubrication is realized.
- the vacuum pump In emergency mode, the vacuum pump is switched off. This leads to an increase of the pressure in the lubricant tank to atmospheric pressure, whereupon lubricant flows from the lubricant tank into the transmission and a wet sump lubrication is realized.
- the disadvantage here is the need to integrate a vacuum generator in the lubrication system.
- Second conveyor which can also promote coolant or lubricant from the tank into the machine when an operating power supply fails, one obtains in a secure manner a supply that produces a dry sump operation in normal operation and is suitable for emergency operation, flood the machine with coolant and / or lubricant to produce emergency cooling / emergency lubrication. Only one tank is needed.
- the second conveyor allows a high degree of flexibility in the technical design and the structural arrangement.
- the lubrication system according to the invention is significantly more energy-efficient, in particular because of the omission of a vacuum pump, than known lubrication systems according to the prior art, see above.
- the optimum lubricant level and thus also the optimum efficiency are achieved with the lowest possible churning losses in the transmission, without the service life or the load capacity of the components dropping.
- the first conveyor can in normal operation, e.g. Use a pump coupled to the gearbox to pump the lubricant out of the lubricant reservoir through a lubricant circuit.
- the invention associated with the lubricant tank second conveyor may have a pressure accumulator and / or a compressor.
- the second conveyor comprises a pneumatic pressure accumulator and a compressor.
- the compressor can be used on the one hand to increase the pressure in the lubricant tank and the lubricant level in the transmission, and on the other hand, to fill the pressure accumulator after it has increased the pressure in the lubricant tank.
- the construction for increasing the pressure in the lubricant tank is advantageously redundant in this respect.
- the second variant is particularly useful when an increase in pressure in the lubricant tank with the compressor was temporarily not possible and therefore the pressure accumulator has jumped. For example, this could happen if the compressor is driven by an electric motor and the power supply suddenly fails.
- the second conveying device comprises a pneumatic pressure accumulator, for example in the form of a gas cylinder.
- the accumulator must be replaced after emptying or manually refilled.
- the advantage here is the simple and space-savingprine the second conveyor.
- the second conveyor comprises a hydraulic pressure accumulator, which is hydraulically connected to the lubricant tank as well as the transmission. Charged the hydraulic pressure accumulator, for example via the different displacement of two different sized hydraulic motors that can be driven, for example, by the lubricant flow from the lubricant circuit.
- FIG. 1 shows a first embodiment of the supply system according to the invention with a first conveying device for conveying smelting agent in a normal mode and with a pneumatic second conveying device.
- Fig. 2 shows a detail of the second conveyor according to a second embodiment of the invention.
- FIG. 3 shows a third embodiment according to the invention with a second delivery device with a hydraulic accumulator.
- the essential components of the arrangement shown in Fig. 1 are the transmission 1 with its oil sump 14 and a closed lubricant tank 2.
- a valve 3 and a valve 8 are under power.
- the lubricating system is relieved atmospherically via the valve 8, so that the lubricant flows in the present embodiment via a geodetic height difference .DELTA. ⁇ from the oil sump 14 of the transmission 1 in the lubricant tank 2.
- Other principles to achieve this are known.
- the transmission 1 switches is lubricated in this way in a normal operation on dry sump.
- a mechanical pump 4 coupled to the transmission 1 and an electric pump 5 ensure the lubrication of the transmission 1.
- a filter 6 filters the lubricant before it enters the gearbox.
- the lubricant tank 2 can be pressurized via the valve 8 by using a compressor 11, a valve 9 or a pressure accumulator 10, whereby the lubricant is pressed back into the transmission 1.
- valve 3 and valve 8 are not energized.
- a lubricant level in the gearbox can also be regulated via the switching time of valve 8.
- An uncontrolled discharge of the pressure accumulator 10 is prevented by a throttle 12. If the electrical power supply collapses, the lubricant is also pushed back into the transmission 1 via the pressure accumulator 10 preloaded by the compressor 11. The adequate lubrication in case of power failure is guaranteed.
- Valve 3 prevents in these operations, the unwanted backflow of the lubricant in the lubricant tank.
- a pipe bend 7 separates the hydraulics from the pneumatics.
- the pressure accumulator 10 can be recharged at any time from the compressor 1 1 via a check valve 13.
- the second embodiment of the invention uses a simplified second conveyor, which can be seen in FIG. On the compressor 1 1 was omitted.
- the solution is suitable only for a limited number of flooding of the transmission 1 with lubricant, for example, only at Power failure.
- the pressure accumulator 10 or gas cylinder 10 may need to be replaced or refilled for the restart of the transmission 1.
- the embodiment shown in Fig. 3 uses a second conveyor with a hydraulic accumulator 15 and with hydraulic motors 16, 17.
- the hydraulic accumulator 15 is loaded via the check valve 25 and valve 26 due to the different displacement of the hydraulic motors 16, 17.
- the large hydraulic motor 16 acts here as a drive, which is set in motion by the pressure and volume flow of the lubrication circuit.
- the smaller of the two hydraulic motors 17 loads the hydraulic accumulator 15.
- the throttles 18 and 23 ensure during the charging process, the sufficient lubrication of the transmission by dividing the flow through the back pressure. In case of power failure or if the lubricant level in the transmission 1 is to be increased, is none of the valves 3, 19, 26 under power.
- the small hydraulic motor 17 then drives with the energy from the hydraulic accumulator 15 to the large hydraulic motor 16, which in turn promotes the lubricant from the lubricant tank 2 via a check valve 24 back into the transmission 1.
- the throttle 22 controls the speed of the discharge.
