Description
Technical field
The utility model relates to a kind of miniature gas turbine generator mounting technique, specially refers to a kind of high-speed micro gas turbine powered generator mounting structure.
Background technique
In some high-tech sector, adopt miniature gas turbine as power source, more than it turns scooter 90000r/min.For making full use of the power source of gas turbine, need to generator be installed at the inlet end of gas turbine, with to system power supply.Prior art high-speed micro gas turbine powered generator mounting structure adopts generator fitting seat generator to be arranged on to the inlet end of gas turbine conventionally.Because the part between gas turbine support and generator support is more, cause the coaxality of gas turbine and motor poor, simultaneity factor rigidity is also low; Existing inlet casing and generator fitting seat structure space do not allow instrument to stretch into from inlet end, nut before centrifugal impeller and compression is removed to material, thereby cannot realize dynamic balancing; In addition, the intake duct area that inlet casing and generator fitting seat form is little, and air-flow sudden change obviously.Obviously, prior art high-speed micro gas turbine powered generator mounting structure exists the coaxality that affects generator shaft and gas turbine axle, motor and gas engine coupling stiffness can not meet, after assembling, can not go to expect dynamic balancing, affect the air inlet effect of gas turbine, to making, complete machine operational vibration is large, and efficiency is low.
Summary of the invention
For solving prior art high-speed micro gas turbine powered generator mounting structure, exist the coaxality that affects generator shaft and gas turbine axle, motor and gas engine coupling stiffness can not meet, after assembling, can not go to expect dynamic balancing, affect the air inlet effect of gas turbine, to making, complete machine operational vibration is large, and efficiency is low.The utility model proposes a kind of high-speed micro gas turbine powered generator mounting structure.The utility model high-speed micro gas turbine powered generator mounting structure arranges support plate on generator housing, and described support plate is the symmetrical wing and setting that recedes, and generator housing and support plate are whole processing structure; The end face of support plate coordinates with the conical surface of inlet casing, and adopts screw to be fixed on inlet casing central position, and inlet casing adopts screw to be fixed on Diffuser or Diffuser cover.
Further, in the utility model high-speed micro gas turbine powered generator mounting structure, inlet casing and Diffuser cover, by one-body molded and be fixed by screws on Diffuser, are processed the coaxality that guarantees the two by combination; Also increased the coupling stiffness of motor and gas turbine.The utility model high-speed micro gas turbine powered generator mounting structure is provided with locating stud between inlet casing and Diffuser, and guaranteeing still has higher coaxality after dismounting.
Further, the utility model high-speed micro gas turbine powered generator mounting structure is provided with the adjusting bolt of inlet casing coaxality in Diffuser shroud rim, between inlet casing and Diffuser cover, be provided with sealing, guarantees its coaxality and sealing.
The useful technique effect of the utility model high-speed micro gas turbine powered generator mounting structure is the high-axiality requirement that can guarantee that generator is installed, do not affect the air inlet effect of gas turbine, after can assembling, go to expect dynamic balancing, meet motor and gas engine coupling stiffness, thereby the vibration of complete machine, inlet loss are met the demands, can be normally, efficient operation, reach higher reliability.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model high-speed micro gas turbine powered generator mounting structure embodiment 1 structural representation;
Accompanying drawing 2 is structural representations of the utility model high-speed micro gas turbine powered generator mounting structure embodiment 2.
Below in conjunction with the drawings and specific embodiments, the utility model high-speed micro gas turbine powered generator mounting structure is further described.
Embodiment
Accompanying drawing 1 is the utility model high-speed micro gas turbine powered generator mounting structure embodiment 1 structural representation, and in figure, l is gas turbine, 2 is generator, 3 is inlet casing, and 4 is Diffuser, and 5 is coupling, 6 is screw, 7 is locating stud, and 8 is bolt, and 11 is gas turbine axle, 21 is generator shaft I, and 22 is support plate.As seen from the figure, the utility model high-speed micro gas turbine powered generator mounting structure arranges support plate 22 on generator 2 housings, and described support plate 22 is the symmetrical wing and setting that recedes, and generator housing and support plate 22 are whole processing structure; The tubaeform cambered surface of the external frame of support plate 22 and inlet casing 3 matches, and adopts screw 6 to be fixed on inlet casing 3 central positions, and inlet casing 3 adopts bolt 8 to be fixed on Diffuser 4.For guaranteeing the coaxality of generator and gas turbine, the utility model high-speed micro gas turbine powered generator mounting structure embodiment 1 is provided with locating stud 7 between inlet casing 3 and Diffuser 4, guarantees coaxality between the two; Because support plate and generator body are whole processing structure, the end face of support plate coordinates with the conical surface of inlet casing, and adopts screw to be fixed on inlet casing central position, processes the coaxality of assurance generator shaft and inlet casing by combination.Thereby support plate 22 makes inlet casing axis size decreases by rear-inclined design, form enough large space and guarantee that instrument stretches into that nut goes to expect to centrifugal impeller with before compressing, thereby realize dynamic balancing, support plate 22 direct (by one-body molded) is connected also and has further increased and removed material space with generator 2, and, when generator housing and inlet casing temperature distortion, the inclination symmetric design due to support plate, can guarantee coaxality equally.And support plate is the symmetrical wing and design that recedes, guarantee not affect the air inlet effect of gas turbine.In general, after model utility high-speed micro gas turbine powered generator mounting structure can guarantee gas turbine and generator assembling, operational vibration meets the demands, thereby complete machine can normally be worked, and reliability is higher.
Accompanying drawing 2 is structural representations of the utility model high-speed micro gas turbine powered generator mounting structure embodiment 2, and in figure, l is gas turbine, 2 is generator, and 3 is inlet casing, and 4 is Diffuser cover, 5 is coupling, 6 is screw, and 8 is bolt, and 9 is seal ring, 10 adjusting bolts, 11 is gas turbine axle, and 21 is generator shaft I, and 22 is support plate.As seen from the figure, as the utility model high-speed micro gas turbine powered generator mounting structure embodiment 2, employing arranges the adjusting bolt of inlet casing coaxality in Diffuser shroud rim, between inlet casing and Diffuser cover, be provided with the mode of seal ring, guarantee the coaxality of generator and gas turbine.This mode can regulate the coaxality of generator shaft and gas turbine axle after generator installs, and can reach best state.Also can in use for some time, during maintenance, the coaxality of generator shaft and gas turbine axle be regulated.Obviously, although the utility model high-speed micro gas turbine powered generator mounting structure embodiment 2 is structurally slightly aobvious complicated,, more practical.
Obviously, the useful technique effect of the utility model high-speed micro gas turbine powered generator mounting structure is the high-axiality requirement that can guarantee that generator is installed, and can go to expect dynamic balancing by complete machine, does not affect the air inlet effect of gas turbine.While making the joint work of gas turbine and generator, vibration, inlet loss meet the demands, thereby make the complete machine can normal, efficient operation.
