Abstract
A dynamic balance testing method for a rotor of a nuclear-power chemical and volumetric make-up pump comprises the following steps that (1) before assembly, firstly, static balancing testing is independently performed on all impellers in the rotor so that the impellers can conform to the standard regulation range; (2) all the impellers are assembled on a pump shaft, through a three-coordinate measuring machine, beating of the shaft and the concentricity of the outer circles of seal rings of all the impellers relative to holes are respectively checked so as to meet the requirements of drawings; (3) based on a de-weight method, by using a high-speed dynamic balance tester, the rotor component of the nuclear-power chemical and volumetric make-up pump can meet the G2.5 grade standard in the standard regulation ISO1940-1 range; (4) after the nuclear-power chemical and volumetric make-up pump is integrally assembled, pump vibration measurement is performed on a non-driving-end bearing seat testing point, a discharge-end pump cylinder testing point and a driving-end bearing seat testing point, wherein vibration is 0.5 mm/s-1.5 mm/s at all the testing points. According to the testing method, operation is convenient, testing is accurate, product quality is improved, and service life is prolonged.
Description
Technical field:
The present invention relates to rotor dynamic balancing test method, relate in particular to a kind of nuclear powerization and hold small pump rotor dynamic balancing test method.
Background technology:
Various solid of revolution in equipment, due to material is inhomogeneous or blank defect, processing and assembling in the error that produces, while even designing, just have the many factors such as asymmetrical geometric configuration, make solid of revolution when rotated, the centrifugal intertia force that on it, each small particle produces can not be cancelled out each other, centrifugal intertia force is applied on machinery and basis thereof by bearing, cause vibration, produced noise, accelerate bearing wear, shorten mechanical life, when serious, can damage incidents.For this reason, must make its balance accuracy grade that reaches permission to balancing rotor, make so the mechanical vibration amplitude that produces is fallen in allowed limits.Concerning much equipment, not only need in manufacture process, to parts, carry out fine balance, and need to make field monitor and complete machine spot dynamic balance to production run state, people also have higher requirement to dynamic balance test of rotor.Adopt prior art, method to carry out dynamic balance running, effort, time-consuming not only, and can not obtain gratifying result.
Summary of the invention:
Technical matters to be solved by this invention is to provide a kind of easy to operate, and test accurately, is conducive to improve the quality of products, and the nuclear powerization increasing the service life is held small pump rotor dynamic balancing test method.
Technical scheme to be solved by this invention is: nuclear powerization is held small pump rotor dynamic balancing test method, it is characterized in that: comprise the following steps:
1), before assembling, first each impeller in rotor is carried out separately to static balancing test, the unbalanced value of its permission is reached in 1.27 grams, make it meet ISO1940-1 standard specialized range G6.3 grade standard;
2), impeller sets at different levels are contained on pump shaft, the concentricity of the sealing ring cylindrical that checks respectively beating of axle and each impeller by three-coordinates measuring machine to hole, makes it reach the requirement that drawing is less than 0.04mm;
3), with high-speed balancing testing machine, nuclear powerization is held to the grading action balance test of G2.5 that small pump rotor part is pressed ISO1940-1 dynamic balance running standard, adopt duplicate removal method, its residual unbalance, is reached in 0.3g, make it meet ISO1940-1 standard specialized range G2.5 grade standard;
4), nuclear powerization is held after small pump final assembly, non-driven-end bearing seat measuring point, the end pump barrel body examination point that spues, drive end axle bearing measuring point are carried out to the vibration survey of pump, the vibration values recording at each test point place after adjustment is 0.5 ~ 1.5mm/s, lower than the category-A limit value 2.8mm/s of JB/T8097 standard.
The present invention is easy to operate, and test accurately, has improved product quality, has extended to use to receive the order.
Accompanying drawing explanation
Fig. 1 is that nuclear powerization of the present invention is held small pump schematic diagram;
In figure 1, unusual drive end axle bearing measuring point, 2, the pump barrel body end measuring point that spues, 3, drive end axle bearing measuring point.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Nuclear powerization is held small pump rotor dynamic balancing test method, it is characterized in that: comprise the following steps:
1), before assembling, first each impeller in rotor is carried out separately to static balancing test, the unbalanced value of its permission is reached in 1.27 grams, make it meet ISO1940-1 standard specialized range G6.3 grade standard;
2), impeller sets at different levels are contained on pump shaft, the concentricity of the sealing ring cylindrical that checks respectively beating of axle and each impeller by three-coordinates measuring machine to hole, makes it reach the requirement that drawing is less than 0.04mm;
3), with high-speed balancing testing machine, nuclear powerization is held to the grading action balance test of G2.5 that small pump rotor part is pressed ISO1940-1 dynamic balance running standard, adopt duplicate removal method, its residual unbalance, is reached in 0.3g, make it meet ISO1940-1 standard specialized range G2.5 grade standard;
4), nuclear powerization is held after small pump final assembly, non-driven-end bearing seat measuring point 1, the end pump barrel body examination point 2 that spues, drive end axle bearing measuring point 3 are carried out to the vibration survey of pump, the vibration values recording at each test point place after adjustment is 0.5 ~ 1.5mm/s, lower than the category-A limit value 2.8mm/s of JB/T8097 standard.During concrete enforcement, the rotor that the present invention makes nuclear powerization hold small pump has reached very high balance quality, and nuclear powerization is held small pump and is in operation three test points of tool characteristic are tested, and the vibration values recording is:
Vibration values, well below the category-A limit value 2.8mm/s of JB/T8097 standard, has increased substantially product quality, has extended serviceable life.
