In this case, the power take-off 500 facilitates taking off and inputting the first power of the engine into the hydraulic starting system 200 for the hydraulic starting system 200 to operate. Moreover, in practical application of the gas turbine starting system, a worker can select a specific installation position of the power takeoff 500 according to the power required by the hydraulic starting system 200, so that the power takeoff 500 can realize the access of different powers of the engine, and the specific installation position of the power takeoff 500 on the chassis 100 is not limited in the application. Of course, the power takeoff 500 has various specifications, and power that can be extracted from the engine by power takeoff 500 of different specifications is different, and the application does not limit the specific specification of the power takeoff 500.
In the gas turbine starting system disclosed in the embodiment of the present application, the hydraulic starting system 200 may include an oil tank 210, a hydraulic pump 220, and a hydraulic motor 230, an inlet of the hydraulic pump 220 is communicated with the oil tank 210, an outlet of the hydraulic pump 220 is communicated with an oil inlet line of the hydraulic motor 230, an oil return line of the hydraulic motor 230 is communicated with the oil tank 210, the hydraulic motor 230 is connected with the gas turbine 300, so that the second power of the hydraulic motor 230 is transmitted to the gas turbine 300, and the engine is connected with the hydraulic pump 220. So that the engine can transmit the first power to the hydraulic pump 220 to drive the hydraulic motor 230 to operate.
Specifically, after the engine is started, the engine may transmit its first power to the hydraulic pump 220, that is, the engine drives the hydraulic pump 220 to operate, the hydraulic pump 220 may send oil in the oil tank 210 into the hydraulic pump 220 from an inlet of the hydraulic pump 220, and the hydraulic pump 220 may discharge the oil with pressure to the hydraulic motor 230 through an outlet of the hydraulic pump 220, so as to drive the hydraulic motor 230 to operate, and further, the hydraulic motor 230 may drive the gas turbine 300 to operate.
In the gas turbine starting system disclosed in the present application, the rotating speed requirements of the gas turbine 300 at different starting stages are different, and in order to meet the different rotating speed requirements of the gas turbine 300, in a further technical solution, the hydraulic starting system 200 may further include a speed regulating valve 240, and the speed regulating valve 240 is disposed between the hydraulic pump 220 and the hydraulic motor 230, and is respectively communicated with the hydraulic pump 220 and the hydraulic motor 230.
Under the above circumstances, the hydraulic pump 220 can discharge the oil with pressure to the speed control valve 240 through the outlet of the hydraulic pump 220, the opening degree of the valve of the speed control valve 240 is adjusted, so as to adjust the oil amount entering the hydraulic motor 230, the oil amount entering the hydraulic motor 230 is different, the rotating speeds of the hydraulic motor 230 are different, and the hydraulic motors 230 with different rotating speeds can be connected with the gas turbine 300 through the clutch or the reducer, so as to realize different rotating speeds of the gas turbine 300, and further, different rotating speed requirements at different stages when the gas turbine 300 is started can be met. That is, the governor valve 240 can regulate the amount of oil passing through, so as to meet different requirements for the rotation speed at different stages when the gas turbine 300 is started.
Since the hydraulic motor 230 has different oil quantities entering the hydraulic motor 230 at different rotation speeds, that is, the oil quantity entering the speed regulating valve 240 from the outlet of the hydraulic pump 220 and then entering the hydraulic motor 230 varies. Specifically, when the rotation speed of the hydraulic motor 230 is low, the opening degree of the speed regulating valve 240 is low, so that the amount of oil that needs to be discharged from the outlet of the hydraulic pump 220 to the speed regulating valve 240 is low, at this time, in the case that the hydraulic pump 220 is a fixed displacement pump, the amount of oil discharged from the outlet of the hydraulic pump 220 may be larger than the amount of oil allowed to pass through the speed regulating valve 240, so that the outlet of the hydraulic pump 220 may overflow, in order to avoid the overflow of oil from the outlet of the hydraulic pump 220, in a further technical solution, the hydraulic starting system 200 may further include a first bypass valve 250, an inlet of the first bypass valve 250 is communicated with the outlet of the hydraulic pump 220, and an outlet of the first bypass valve 250 is communicated with the oil tank 210. The first bypass valve 250 may specifically be a relief valve, such as a pressure relief valve, a flow relief valve, and the like, and the specific type of the first bypass valve 250 is not limited in the embodiment of the present application. Of course, a common on-off valve may be used.
In the above case, when the amount of oil introduced into the governor valve 240 is smaller than the amount of oil discharged from the outlet of the fixed displacement pump, the excessive amount of oil discharged from the outlet of the fixed displacement pump can be returned to the oil tank 210 through the first bypass valve 250, so that the oil can be prevented from overflowing from the outlet of the hydraulic pump 220.
In another alternative, the hydraulic pump 220 may be a variable displacement pump. In this case, in the case that the amount of oil allowed to pass through the governor valve 240 is changed, the amount of oil discharged from the outlet of the variable displacement pump can be adaptively changed to adapt to the adjustment of the governor valve 240 to the rotation speed of the hydraulic motor 230, and at this time, the first bypass valve 250 is not required to be disposed at the outlet of the hydraulic pump 220, which is beneficial to simplifying the overall configuration of the hydraulic starting system 200.
In the gas turbine starting system disclosed in the embodiment of the present application, the hydraulic starting system 200 may further include a filter, and a filter is disposed between the oil tank 210 and an inlet of the hydraulic pump 220, and/or a filter is disposed between an oil return line of the hydraulic motor 230 and the oil tank 210. Optionally, the filter may include a first filter 260, and the first filter 260 is disposed between the oil tank 210 and the inlet of the hydraulic pump 220 and is in communication therewith. Under the condition, the oil flowing into the hydraulic pump 220 from the oil tank 210 passes through the first filter 260, so that the first filter 260 can filter impurities and particles of the oil, thereby being beneficial to the good operation of the components such as the hydraulic pump 220 and the hydraulic motor 230, namely, the problem that the impurities and the particles in the oil wear the components such as the hydraulic pump 220 and the hydraulic motor 230 can be relieved, and further being beneficial to the good operation of the whole hydraulic starting system 200.
In the gas turbine starting system disclosed in the embodiment of the present application, optionally, the filter may further include a second filter 270, and the second filter 270 is disposed between the oil return line of the hydraulic motor 230 and the oil tank 210, and is in communication with both. Under the condition, the oil liquid flowing back to the oil tank 210 from the oil return pipeline of the hydraulic motor 230 passes through the second filter 270, so that the second filter 270 can filter impurities and particles in the oil liquid flowing back to the oil tank 210, the impurities and particles in the oil liquid flowing back to the oil tank 210 can be reduced, the circulation of the oil liquid in the oil tank 210 in the whole hydraulic starting system 200 is favorably reduced, and the abrasion problem of elements and pipelines in the hydraulic starting system 200 is solved.
The hydraulic starting system 200 of the present application may include both the first filter 260 and the second filter 270, or may include only one of them, and may be selectively installed by a worker according to the quality of the oil and the use requirement, and the number and the installation position of the filters are not particularly limited in the present application.
In the case that there are many impurities and particles in the oil or the second filter 270 is used for a long time, the second filter 270 may be blocked by the impurities and the particles, and at this time, the oil in the oil return line of the hydraulic motor 230 cannot flow back to the oil tank 210 through the second filter 270, which results in that the whole hydraulic starting system 200 cannot continue to operate.
To avoid this, in a further embodiment, the hydraulic starting system 200 may further include a second bypass valve 280, an inlet of the second bypass valve 280 is communicated with the return line of the hydraulic motor 230, and an outlet of the second bypass valve 280 is communicated with the oil tank 210. In this case, when the second filter 270 is clogged, the oil in the oil return line of the hydraulic motor 230 can flow back to the oil tank 210 through the second bypass valve 280, so that it is possible to prevent the entire hydraulic starting system 200 from being stopped immediately due to clogging of the second filter 270, that is, the provision of the second bypass valve 280 can alleviate an adverse effect on the operating state of the hydraulic starting system 200 after clogging of the second filter 270.
In case of an abnormality of the hydraulic motor 230, the oil pressure in the oil return line of the hydraulic motor 230 may be lower than the oil pressure in the oil tank 210, which may cause the hydraulic motor 230 to suck the oil in the oil tank 210 back to the oil return line through the second bypass valve 280, and even suck the oil back to the hydraulic motor 230, thereby affecting the operation of the whole hydraulic starting system 200. To avoid this, in a further aspect, the second bypass valve 280 may be a check valve that is open in a direction that the oil flows from the hydraulic motor 230 to the oil tank 210. Under the condition, the one-way valve can only realize conduction in the flowing direction of the hydraulic motor 230 to the oil tank 210, so that the oil in the oil tank 210 can be prevented from flowing back to the hydraulic motor 230 through the one-way valve, the normal operation of the hydraulic starting system 200 is further influenced, and the normal operation of the whole gas turbine starting system is further influenced.
In the gas turbine starting system disclosed in the embodiment of the present application, the hydraulic starting system 200 may further include an accumulator that is disposed on a pipeline between the hydraulic motor 230 and the hydraulic pump 220 and is in communication therewith. In this case, when the oil amount required in the hydraulic motor 230 is smaller than the oil amount discharged from the outlet of the hydraulic pump 220, the accumulator can temporarily store the excessive oil amount discharged from the outlet of the hydraulic pump 220, and when the oil amount required in the hydraulic motor 230 is larger than the oil amount discharged from the outlet of the hydraulic pump 220, the accumulator can discharge the previously stored oil amount to compensate for the oil shortage at the outlet of the hydraulic pump 220. That is to say, the accumulator can stabilize the demand of the hydraulic pump 220 to the hydraulic motor 230 with different oil quantities, so that the hydraulic motor 230 can be switched smoothly in different rotating speeds, and the stability of the gas turbine 300 in the operation process can be improved.
In the gas turbine starting system that this application embodiment discloses, gas turbine starting system can also include thermostat and radiator, and the thermostat is linked together with the radiator, thermostat and radiator set up in between the export of hydraulic pump 220 and hydraulic motor 230's the oil inlet pipe way to make thermostat and radiator can realize the adjustment to the temperature of the export exhaust fluid of hydraulic pump 220, and then can avoid the high or low normal operating that influences whole hydraulic starting system 200 of crossing of the temperature of fluid in the hydraulic pump 220.
