Abstract
Can be used for a Balance disc rotor structure for Compressor test part, it is characterized in that: the described Balance disc rotor structure that can be used for Compressor test part, comprises drum barrel axle, attachment bolt, Balance disc, plate nut; Wherein: the rear end of drum barrel axle is connected with Balance disc by attachment bolt, the rear portion of Balance disc is provided with plate nut.The top of described Balance disc is with two-layer labyrinth gas seals structure.Advantage of the present utility model: install the Balance disc rotor stack that this patent proposes at rotor-support-foundation system rear portion additional, realizes the axial equilibrium of forces of Compressor test part.Balance disc assembly parts can according to different compressor rotor structures, key effect is had in adjustment rotor dynamics characteristic, can under the prerequisite meeting intensity and counterbalance effect, adjustment partial structurtes, the quality changing Balance disc assembly parts just can realize the critical speed of rotation adjusting compressor rotor, make it avoid working speed, meet the demand for security of the rotor-support-foundation system that runs up.
Description
Technical field
The utility model relates to Compressor test part design field, particularly a kind of Balance disc rotor structure that can be used for Compressor test part.
Background technique
Along with the development of gas compressor designing technique, in combustion engine beforehand research field, gas compressor progression gets more and more, carrying out compressor part test is inevitable course in development process, and the axial force of testpieces controls to seem particularly important in process of the test, except the balanced capacity of exerciser itself, testpieces self also will have the ability of certain balancing axial thrust.
Compressor rotor rear portion and Balance disc connect formation testpieces rotor-support-foundation system, according to assembly relation, rear drum barrel axle and Balance disc constitute Balance disc rotor stack, see Fig. 1, testpieces rear cavity is divided into Balance disc ante-chamber and Balance disc back cavity by Balance disc, see Fig. 1, according to the size of testpieces axial force, the pressure adjusting two chambeies by air logical in stand bleed and chamber carrys out the safe operation of proof test part.
Model utility content
The purpose of this utility model is for ensureing that the carrying out of Compressor test part safety is tested, at compressor rotor rear portion combination assembling Balance disc rotor stack, the design of Balance disc both can Adjustment Tests part axial force, also can adjust the critical speed of rotation of rotor-support-foundation system, spy provides a kind of Balance disc rotor structure that can be used for Compressor test part.
The utility model provides a kind of Balance disc rotor structure that can be used for Compressor test part, it is characterized in that: the described Balance disc rotor structure that can be used for Compressor test part, comprises drum barrel axle 1, attachment bolt 2, Balance disc 3, plate nut 4;
Wherein: the rear end of drum barrel axle 1 is connected with Balance disc 3 by attachment bolt 2, the rear portion of Balance disc 3 is provided with plate nut 4.
The top of described Balance disc 3 is with two-layer labyrinth gas seals structure.
Described two-layer labyrinth gas seals structure, the number of two-layer comb tooth is not etc.
Because Balance disc rotor stack is assemblied on testpieces rotor-support-foundation system, and be positioned at the chamber of High Temperature High Pressure, the Intensity Design of Balance disc, ability of obturaging, assembling are all the claim points that this patent proposes.
In order to ensure assembling reasonable, the plate nut in Balance disc rear design, had so both ensured easy to assembly, had again saved the space of rear fulcrum, ensure that the span of testpieces.
The design gaps of Balance disc top comb tooth and coating, namely to ensure to touch the excessive testpieces that causes that rubs to vibrate, ensure the reliability of obturaging again, can not leak gas, by the calculating of professional software, devise according to the radial displacement of Balance disc gap of reasonably obturaging and ensure that Balance disc separates the function of pressure chamber.
Advantage of the present utility model:
The Balance disc rotor structure that can be used for Compressor test part described in the utility model, have the prerequisite of demand at Compressor test part under, by installing the Balance disc rotor stack that this patent proposes additional at rotor-support-foundation system rear portion, can realize the axial equilibrium of forces of Compressor test part.Balance disc assembly parts can according to different compressor rotor structures, key effect is had in adjustment rotor dynamics characteristic, can under the prerequisite meeting intensity and counterbalance effect, adjustment partial structurtes, the quality changing Balance disc assembly parts just can realize the critical speed of rotation adjusting compressor rotor, make it avoid working speed, meet the demand for security of the rotor-support-foundation system that runs up.
