Abstract
The invention discloses a test rotor. The test rotor comprises a test section and a main body section which are split, wherein the test section is axially arranged on the main body section, and the test section is replaced on the main body section according to test requirements. According to the invention, based on test characteristics in the process of rotor research and development, and on the premise of ensuring the validity and reliability of test operations, the test rotor is divided into the main body section with universality and the test section which can be replaced and changed correspondingly according to the test requirements of different test stages, so that the test rotor has a certain degree of universality, and can be repeatedly used, thereby achieving the purpose of effectively saving the research and development resources (include materials, manpower, equipment, time, and the like) of new products, and then reducing the test cost, shortening the test cycle, speeding up the pace of research and development of new products, and seizing market opportunities, so, the test rotor is strong in practicability.
Description
Technical field
The present invention relates to rotary part and carry out the trial target reached for performance test, for example performance test in turbine rotor or other equipment (as chemical plant) main shaft R&D process.
Background technology
Along with the development of steam turbine industry, the rotor structure of steam turbine is more and more diversified.In the R&D process of the rotor of steam turbine before putting into production use, need to carry out a lot of and loaded down with trivial details testing experiment to the rotor of newly designing, various mechanical propertys with the checking rotor, rotor reliability after guarantee puts into production use, these tests include but not limited to, moving frequency modulation test and stage efficiency test, the strength test of blade root and the wheel rim strength test of blade root etc. of blade.Due to the content difference of each test, just need to, when each test, newly design, produce the test rotor of Pass Test requirement.Yet, the test rotor is structurally similar, this each test just redesigns, produces new test rotor, can cause various resources (comprising material, manpower, equipment, time etc.) profligacy, and then increase experimentation cost, extend the test period, thereby restricted the research and development paces of new product, be unfavorable for seizing the first market opportunities, extremely impracticable.
Summary of the invention
The object of the invention is to: for above-mentioned the deficiencies in the prior art, under the prerequisite of guaranteeing the testing operation validity and reliability, provide a kind of and can reuse, effectively save research and development of new product resource, practical test rotor.
The technical solution used in the present invention is: a kind of test rotor, and described test rotor comprises test section and the main paragraph of split, and described test section axially is assemblied on main paragraph, and test section is changed on main paragraph according to testing requirements.
Further, described test section axially is assemblied on main paragraph by clamping screw.
Further, the end face of described main paragraph is provided with a plurality of bolts hole, and these bolts hole are circumferentially uniform; Described test section is provided with a plurality of bolts hole corresponding with the bolt hole on main paragraph.
Further, described test section is one or more levels wheel disc; Described multistage wheel disc is axially combined.
The invention has the beneficial effects as follows: according to the test feature in the rotor R&D process, under the prerequisite of guaranteeing the testing operation validity and reliability, the test rotor is divided into to main paragraph with versatility and testing requirements that can the corresponding different tests stage and changes the test section of variation, make to test rotor with this and there is versatility to a certain degree, can reuse, reach effective saving research and development of new product resource and (comprise material, manpower, equipment, time etc.) purpose, and then reduction experimentation cost, shorten the test period, accelerate the research and development paces of new product, seize the first market opportunities, practical.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is a kind of structural representation of the present invention.
Code name implication in figure: 1-test section; 1-1-first order wheel disc; 1-2-second level wheel disc; 2-clamping screw; 3-main paragraph.
Embodiment
Now take the turbine rotor research and development as example, describe the present invention in detail.Shown in Figure 1: the present invention includes test section 1 and main paragraph 3, this test section 1 and main paragraph 3 are separate Split type structure.Be processed with a plurality of bolts hole on the end face of aforementioned body section 3, these bolts hole are circumferentially uniform on the end face of main paragraph 3.Also be processed with a plurality of bolts hole on afore-mentioned test section 1, the number of bolt hole on test section 1 not necessarily must equal the number of bolt hole on main paragraph 3, but on test section 1, the setting position of these bolts hole must form with the bolt hole on main paragraph 3 a plurality of corresponding.In the bolt hole corresponding with main paragraph 3, clamping screw 2 is housed respectively at test section 1, these clamping screws 2 axially are assemblied in test section 1 on main paragraph 3, with this, are combined into a complete test rotor, carry out testing operation.After testing operation, in the time of need to carrying out the next item down testing operation, by the operation to clamping screw 2, test section 1 is unloaded from main paragraph 3, change the test section that Pass Test requires, the test section that to newly change by the operation to clamping screw axially is assemblied on main paragraph, is combined into new complete test rotor, carries out corresponding testing operation.That is to say, test section 1 of the present invention is changed on main paragraph 3 according to the testing requirements in different tests stage, and main paragraph 3 has versatility, can be reusable.
Above-mentioned test section 1, according to testing requirements, consists of the two-stage wheel disc, i.e. first order wheel disc 1-1 and second level wheel disc 1-2, and first order wheel disc 1-1 and second level wheel disc 1-2 axially combine, and by common clamping screw 2, are assemblied on main paragraph 3.The wheel disc progression of afore-mentioned test section determines jointly according to structure and the testing requirements of research and development new product.
The structural strength of above-mentioned clamping screw and tighten dynamics, should determine according to the test moment to the test rotor in testing operation.
Foregoing is to using turbine rotor research and development to describe the present invention in detail as example, certainly, technical scheme of the present invention, except being applicable to turbine rotor research and development, can also be applicable to the research and development of other rotary part, such as the chemical plant main shaft of High Rotation Speed etc.The test section of above-mentioned test rotor and main paragraph assembly structure can adopt other connected mode to replace, such as pin joint, joggle etc., but for convenience, reliability and the validity of testing operation, preferred bolt connected mode.
