Description
Technical field
The utility model relates to a kind of steam turbine and is used for the dynamic balancing setting tool of steam turbine.
Background technique
Steam turbine all needs to carry out the field high-speed dynamic balancing after rotating part is carried out overhaul of the equipments, the shafting vibration that brings owing to reasons such as mass unbalances with the elimination rotor exceeds standard.Existing steam turbine when carrying out high-speed balancing, need be with unit outage, destroy vacuum after, operator's hole door from the low pressure (LP) cylinder enters into steam turbine inside to carry out balancing weight and installs additional.Steam turbine is stopped transport to from red switch test and is entered low pressure (LP) cylinder inside and install balancing weight additional and finish and generally need about 24 hours, greatly reduces manufacturing efficiency, causes than large economy and loses.And low pressure (LP) cylinder built-in function space is narrow and small, need carry out pincers worker and electric fiery welder's work, the danger that therefore also can bring the person and equipment.
The model utility content
For problems such as the dynamic balancing complicated operation, the operation cycle that solve existing steam turbine are long, the utility model provides a kind of steam turbine and has been used for the dynamic balancing setting tool of steam turbine.The technical solution adopted in the utility model is: comprise low pressure (LP) cylinder and rotor and the impeller be located in the low pressure (LP) cylinder, impeller is connected on the rotor, axle big envelope place at described low pressure (LP) cylinder has a window, and the root of described impeller is provided with the screw that matches with the screw section of balancing weight.
Preferably, described window is provided with gasket seal.
Preferably, described gasket seal is a plastic film.
A kind of dynamic balancing setting tool that is used for steam turbine, described setting tool comprises sleeve pipe, is arranged in the swingle and the balancing weight of sleeve pipe, balancing weight has hole and screw section, and first end of swingle cooperates with the hole of balancing weight, and the screw section of described balancing weight cooperates with the screw of impeller root.
Preferably, described swingle second end is a screw rod, and described screw rod matches with nut on it.
Preferably, first end and the balancing weight of swingle pass through screw-thread fit.
The utility model carries out equilibrium block by special-purpose dynamic balancing setting tool and installs by setting up screw at low pressure (LP) cylinder uplifting window mouth with at the impeller root.Need not operator and enter low pressure (LP) cylinder work, only be used in the low pressure (LP) cylinder peripheral operation, the end of operation closed window, the operating time is short, has improved high working efficiency.
Description of drawings
Fig. 1 is the structural representation of the dynamic balancing setting tool of the utility model steam turbine;
Fig. 2 is a steam turbine structural representation of the present utility model.
Embodiment
Steam turbine that the utility model is provided below in conjunction with accompanying drawing and the dynamic balancing setting tool that is used for steam turbine describe in further detail:
As shown in Figure 2, it is steam turbine structural representation of the present utility model, the steam turbine that the utility model provides comprises low pressure (LP) cylinder 1 and rotor 6, low pressure (LP) cylinder 1 and rotor 6 are sealed by axle big envelope 2, axle big envelope 2 places at low pressure (LP) cylinder 1 and rotor 6 have a window 3, impeller 5 is connected on the rotor 6, and impeller 5 roots are provided with screw 4, and screw 4 matches with the screw section of balancing weight 7 to be added.Window 3 is provided with gasket seal.Preferably, gasket seal is a plastic film.
Because low pressure (LP) cylinder inside is negative pressure when normally moving, so need install gasket seal additional, after finishing, construction can realize that locking is tight, ensure unit starting and the not blank gas of run duration, guarantee unit degree of vacuum is kept economical operation.Open during operation, close behind the end of operation and get final product.By the dynamic balancing setting tool equilibrium block is installed in the impeller root.The utility model is realized equilibrium block being installed to low pressure (LP) cylinder inside from the outside, can calculate according to practical application as for the size and the setting angle of equilibrium block.
As shown in Figure 1, the structural representation of dynamic balancing setting tool of the present utility model, dynamic balancing setting tool comprise sleeve pipe 8, are arranged in the swingle 9 and the balancing weight 7 of sleeve pipe 8.First end of swingle 9 cooperates with the hole of balancing weight 7.The front end of balancing weight 7 is provided with the spiral shell button, and the spiral shell button of the front end of balancing weight 7 matches with the screw of impeller root, by swingle 9 balancing weight 7 is pushed low pressure (LP) cylinder 1 from window 3, and balancing weight 7 is installed in the screw of impeller 5 roots.When the screw of window 3 and impeller root during not at corresponding position, only need rotor 6 is rotated, forward the screw of impeller root to and window is corresponding gets final product.
Preferably, swingle 9 second ends are screw rod 11, and screw rod 11 is provided with nut 10 and matches with it.First end and the balancing weight 7 of swingle 9 pass through screw-thread fit.Swingle of the present utility model two ends all have screw rod, and the second end screw rod of swingle 9 cooperates with nut 10, screwing and unscrewing, realization swingle moving forward and backward in sleeve pipe 8 by swingle second end and nut 10.Swingle 9 also adopts screw-thread fit with balancing weight 7, and when swingle 9 advanced in sleeve pipe 8, the screw on balancing weight 7 was screwed in.When balancing weight is installed, balancing weight 7 is stretched into low pressure (LP) cylinder, the spiral shell button of the balancing weight 7 front ends screw 4 with impeller 5 roots is screwed in by revoling tube 8.Balancing weight 7 is screwed in a time-out with the screw 4 of impeller 5 roots, installs, and unscrews nut 10 after installing, and swingle 9 is unloaded from impeller, setting tool is taken out from low pressure (LP) cylinder 1, and shut window 3.
In the turbine rotor dynamic balancing measurement that the utility model carries out.After the stall of low pressure (LP) cylinder rotor, operator open low pressure (LP) cylinder axle big envelope place window, and the balancing weight that adopts the equilibrium block setting tool to weigh screws in the rotor counterweight hole and fixes, and seals the counterweight window then.The integrated operation time has only been used 2 hours 40 minutes, and unit starts again towards car.Relatively originally, carry out a practical operation nearly 23 hours, greatly shortened the operating time, improved working efficiency, evaded the person and equipment risk.
Although the utility model is to be described by above-mentioned preferred embodiment, but it realizes only being not limited to above-mentioned mode of execution, should be realized that under the situation that does not break away from the utility model spirit and scope those skilled in the art can make different variations and modification to the utility model.
