Description

[0002] With the rapid development of the gas turbine industry, the number of gas turbines in operation has increased exponentially, resulting in a large number of gas turbines that need to be overhauled and then undergo factory test runs after the overhaul is completed. Currently, all gas turbine test benches on the market are single-model test benches, so they cannot meet the test run requirements of multiple models of front and rear output gas turbines. Only some models can be tested, resulting in a large number of imported gas turbines having to be returned to the equipment's place of origin for maintenance tests.

[0003] The current traditional solution is to build more types of gas turbine test benches to meet the test needs, but the test bench construction cost is high and wastes manpower and material resources. The characteristics of overhauled gas turbines are that there are many types, but the number of gas turbines of each type is limited. Therefore, if the traditional solution of building multiple types of test benches is adopted, some types of gas turbine test benches will be idle for a long time. Summary of the invention

The common air intake filter and silencer 1 is arranged in a test plant 25. One end of the common air intake filter and silencer 1 is connected to the atmosphere, and the other end is connected to the common air intake flow pipe 2. The common air intake flow pipe 2 in this embodiment has a flow monitoring function, and the pipeline roughness is 1.6~3.2, and the smoothness is relatively high. One end of the front output machine air intake sound insulation channel 3 is connected to the common air intake flow pipe 2, and the other end is used to be connected to the air intake port of the front output type gas turbine main engine 11, one end of the rear output machine air intake sound insulation channel 4 is connected to the common air intake flow pipe 2, and the other end is used to be connected to the air intake port of the rear output type gas turbine main engine 15, and the first blocking plate is used to block the end of the front output machine air intake sound insulation channel 3 or the rear output machine air intake sound insulation channel 4 away from the common air intake flow pipe 2. The first blocking plate in this embodiment can be connected to the end of the front output machine air intake sound insulation channel 3 or the rear output machine air intake sound insulation channel 4 away from the common air intake flow pipe 2 by bolts.

[0039] One end of the rear output machine air intake sound insulation channel 4 in this embodiment is connected to one side of the front output machine air intake sound insulation channel 3, thereby realizing the communication between the rear output machine air intake sound insulation channel 4 and the common air intake flow pipe 2.

[0044] The middle ground rail and the side ground rail 91 in this embodiment are installed below the ground level of the test plant 250 meters, and mainly play a supporting role. For different types of gas turbines, support seats 93 of different heights can be replaced to adapt to the centerline height of each type of gas turbine.

[0049] It can be seen that the test bench system in this embodiment is provided with two positions, one position can be used to test the front output type gas turbine, and the other position can be used to test the rear output type gas turbine, and by adjusting the size and interface of the transfer section of the intake system and the exhaust system close to one end of the gas turbine, and switching the interface of the auxiliary system, it can be realized that one test bench system is suitable for the test requirements of the vast majority of gas turbines on the market, that is, the front output position is suitable for the test requirements of various types of front output type gas turbines, and the rear output position is suitable for the test requirements of various types of rear output type gas turbines. At the same time, in the gas turbine test preparation stage, when testing the two types of gas turbines with front and rear output, there is no need to adjust the position of the double-end input generator 14, the intake system, the exhaust system and the auxiliary system. Compared with the traditional gas turbine test bench system, the gas turbine test preparation cycle is shortened, and there is no need to build multiple types of special test benches, saving floor space and cost. It can be seen that by setting two positions, the test requirements of multiple types of gas turbines can be met, with high adaptability and strong practicality, shortening the test preparation cycle, and improving the utilization rate of the test bench system.
