Abstract
A damping erecting device for gas turbine fuel main pipe, belongings to the domain of damping erecting device technology, whose structure consists of a bumper and an erection supporting plate. The bumper structure comprises a hemline erection base, a main support bar, a damper spring, a locating bush and a compression nut, wherein the main support bar is provided above the hemline erection base, and the upper end of the main support bar is equipped with the compression nut, and the locating bush is equipped around the support bar, and the damping spring is installed between the locating bush and the main support bar. The erection supporting plate is fixed on the locating bush, and is opened with a plurality of adjustable-displacement mounting holes. In erection, the hemline erection base of the bumper is fixed to the gas turbine crankcase, and the fuel main pipe is dead fixed to the erection supporting plate via locating screws. The utility model has the advantages of avoiding the seams at the joint between the fuel main pipe and the crankcase caused by engine vibration in the transportation and the working process, and guaranteeing the normal operation of the gas turbine.
Description
Technical field
The utility model belongs to a kind of damping erecting device technical field, and the damping that is used for reaching between gas turbine and the fuel manifold between the jumbo is installed, and particularly relates to a kind of fuel manifold damping erecting device.
Background technique
Modern gas turbines mostly adopts thick-wall tube as fuel-supply pipe, and purpose is in order to improve its intensity and safety reliability.But because its quality is big, can produce very big active force,, can seminess occur in the joint of fuel manifold and casing through working long hours to casing; For this reason, combustion machine fuel manifold in the past all is fit to ground handling.For promptly being applicable to ground handling, be applicable to the combustion machine of boats and ships work again, the fuel-supply pipe of this thick-wall tube is unsuitable for firing the whole Transporting and the installation of machine.
The model utility content
In order to solve the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of gas turbine fuel house steward damping erecting device, by this device gas turbine and fuel manifold is linked into an integrated entity, and makes things convenient for the whole Transporting and the installation of combustion machine.
Structure of the present utility model, comprise vibration damper, support plate is installed, its vibration damper structure comprises base fitting seat, main support rod, damping spring, positioning adapter, gland nut, the base fitting seat is used for fixedlying connected with the casing of gas turbine, above the fitting seat of base, be equipped with main support rod, the main support rod upper end is equipped with gland nut, positioning adapter is installed around the main support rod, between positioning adapter and main support rod, damping spring is installed, is used to eliminate the vibration stress between fuel manifold and the casing; Support plate is installed to be fixed on the positioning adapter of vibration damper, be used for fixing fuel manifold, on the installation support plate, have several displacement-adjustable mounting holes, the position of displacement-adjustable mounting hole and number based on fuel house steward's position, size and decide, when fuel manifold is installed, positioning screwn can move up and down in the displacement-adjustable mounting hole, convenient fuel house steward's installation.Between the base fitting seat and main support rod of vibration damper, between positioning adapter and the installation support plate for being welded to connect.
The utility model is to install like this: the base fitting seat of vibration damper is fixed on the casing of gas turbine, and fuel manifold is fixedlyed connected with the installation support plate by positioning screwn.According to actual needs, can be fixed on side by side on the installation support plate organizing vibration damper more.
The utility model has the advantages that in transportation and working procedure, avoided causing the seminess of fuel manifold and the appearance of casing joint, guaranteed the normal operation of combustion machine because of engine luggine.
