Description

Technical Field

[0001] The invention belongs to the field of power machinery engineering and relates to a standardized transformation method, system, equipment and medium for a dynamic balance influence coefficient. Background Art

[0002] Balancing refers to adjusting the mass distribution of the rotor to reduce the vibration or bearing dynamic reaction force caused by imbalance to within the allowable range. Taking a steam turbine generator set as an example, among its various vibration faults, vibration caused by imbalance accounts for about 70%. For rotating equipment such as pumps and fans, the situation is similar. Therefore, dynamic balancing has become an important means of vibration elimination for rotating equipment.

[0003] Dynamic balancing can comprehensively consider the impact of each stage of design, manufacturing, transportation, installation, and operation. When a rotating device has a vibration problem, its balance should be considered first. If there are other faults besides imbalance, the imbalance is generally eliminated first. This is done for the following reasons: ① It is conducive to reducing the vibration base and improving the safety margin; ② Imbalance is often a factor that induces other vibration faults; ③ The implementation of dynamic balancing is relatively simple and the workload is small. Therefore, even if there are faults other than balance, as long as the vibration can be improved through dynamic balancing, dynamic balancing should be chosen first.

[0004] The influence coefficient method is widely used in dynamic balancing calculations because of its clear concepts and principles, easy compilation of automated calculation programs, and high calculation accuracy. However, due to the various installation methods of key phase sensors and vibration measurement sensors for different rotating equipment, the influence coefficients that have been obtained cannot be conveniently used on other equipment with similar structures, resulting in a large number of equipment startups and time occupied when using dynamic balancing vibration elimination, and low timeliness. For example, the cost of starting a large steam turbine generator set is as high as hundreds of thousands of yuan, which does not include the loss of power generation of the unit. Therefore, it is particularly important to enhance the universality of the influence coefficient and make dynamic balancing vibration elimination more accurate and efficient. Based on this background, it is of great significance to perform standardized transformation of dynamic balancing influence coefficients. Summary of the invention

[0077] Embodiment 2

[0078] Taking the vibration problem of a 1000MW steam turbine generator set in a power plant as an example, the detailed implementation process of the present invention is introduced to illustrate the effectiveness and practicality of the present invention.

[0079] The steam turbine of the No. 1 steam turbine generator unit of a power plant is a N1000-26.25 / 600 / 600 (TC4F) supercritical, single-intermediate reheat, single-shaft, four-cylinder, four-exhaust, condensing steam turbine, equipped with a QFSN-1000-2 water / hydrogen / hydrogen cooling generator. The unit's shaft system consists of a high-pressure rotor, an intermediate-pressure rotor, a low-pressure 1 rotor, a low-pressure 2 rotor, a generator rotor, and an excitation shaft. The shaft system is supported by 8 bearings. The shaft system structure diagram is as follows: Figure 2 The actual installation position of the key phase sensor and relative shaft vibration sensor is shown in Figure 3 shown.

[0080] The unit was subjected to the B-level overhaul and the generator rotor was removed. After the overhaul, the relative shaft vibration at the #8 bearing was seriously exceeded the standard at rated speed, reaching a maximum of about 230μm, and the unit could not operate safely. Taking advantage of the opportunity of unit shutdown to eliminate faults, dynamic balancing was implemented in the fan ring balance groove between the positive and negative collector rings, successfully improving the vibration at this measuring point.

[0081] The specific implementation steps are as follows:

[0082] 1) Determine the rotation direction of the rotating equipment;

[0083] The rotating equipment is a steam turbine generator set, so the direction of rotation should be determined by looking from the steam turbine to the generator. The direction of rotation is determined to be clockwise on site. Figure 3 As shown in ω.

[0084] 2) Define the standard installation positions of key phase sensors and relative shaft vibration sensors;

[0085] The standard installation position of the sensor is Figure 3 The location of Key, SL, and SR in the.

[0086] 3) Obtain the actual installation positions of the key phase sensor and the relative shaft vibration sensor of the rotating equipment under test;

[0087] Depend on Figure 3 It can be seen that the key phase sensor Key0 is actually installed on the right side, and the angle formed by it and the standard installation position of the key phase sensor is θ = 55° or 305°. The power plant calls the relative axis vibration sensor actually installed on the left side X, and the angle formed by it and the standard installation position of the relative axis vibration sensor on the left side is Or 315°, the power plant calls the relative axis vibration sensor actually installed on the right side Y, and the angle formed by it and the standard installation position of the relative axis vibration sensor on the right side is or 315°.

[0088] 4) Calculate the dynamic balance influence coefficient at a certain measuring point of the rotating equipment under test.

[0089] The fundamental frequency components of the relative axis vibration of 8X and 8Y before dynamic balancing are:

[0090]

[0091] The dynamic balancing weight is:

[0092]

[0093] After dynamic balancing, the fundamental frequency components of the relative axis vibration of 8X and 8Y are:

[0094]

[0095] The influence coefficient is:

[0096]

[0097] A l ′=0.225 β l ′=249

[0098]

[0099] A r ′=0.106 β r ′=305

[0100] 5) The obtained 8X and 8Y relative axis vibration influence coefficients are standardized.

[0101] 51) Standardize the key phase sensor position;

[0102] Depend on Figure 3 It can be seen that the key phase sensor position is standardized by moving the key phase sensor Key0 to the position of the key phase sensor Key. When moving in the reverse rotation direction, θ=55°, and n is 1; if moving in the forward rotation direction, θ=305°, and n is 2.

[0103]

[0104] Among them, - indicates the direction of counter-rotation, so -56° and 304° are actually the same angle.

[0105]

[0106] Among them, 0° and 360° are the same angle.

[0107] 52) Standardization of relative shaft vibration sensor position

[0108] Depend on Figure 3It can be seen that the standardization of the relative axis vibration sensor position on the left is to move the relative axis vibration sensor X to the SL position. If it moves in the reverse rotation direction, then m is 1; if it moves in the forward direction of rotation, then m is 2.

[0109]

[0110] Among them, - indicates the reverse rotation direction.

[0111] Depend on Figure 3 It can be seen that the standardization of the relative axis vibration sensor position on the right side is to move the relative axis vibration sensor Y to the SR position. If it moves in the reverse rotation direction, then m is 1; if it moves in the forward direction of rotation, then m is 2.

[0112]

[0113] The final standardized influence coefficient is:

[0114]

[0115] Among them, - represents the counter-rotation direction, so -11° and 349° are actually the same angle.

[0116] At this point, the relative shaft vibration dynamic balance influence coefficient at the unit's #8 bearing has completed standardized transformation. Subsequent equipment with similar structures can directly use this influence coefficient for dynamic balance calculations, which can greatly improve the efficiency of dynamic balancing vibration elimination and reduce the number and duration of unit starts.
