Embodiment 1

[0024] Embodiment 1 (experiment one)

[0025] When no adjusting shim 15 is added between the thrust bearing 14 and the thrust head 13 and no adjusting shim 12 is added between the rigid coupling 11, measure the remaining swing of the motor shaft 8 and the water pump shaft 9. Record the readings of dial indicator 1 21, dial indicator 2 22 and dial indicator 3 23, and calculate the swing value and its orientation. The remaining swing should be very small and within the acceptable range.

Embodiment 2

[0026] Embodiment 2 (experiment two)

[0027] Add the adjustment gasket 2 15 on the side between the thrust bearing 14 and the thrust head 13, and calculate the swing value and its value at the flange of the rigid coupling according to the thickness of the adjustment gasket 2 15 and the relevant dimensions of the device. position. Measure and calculate the maximum value and azimuth of the swing at the flange of the rigid coupling with the dial gauge 222, and compare and analyze with the calculated predicted value.

Embodiment 3

[0028] Embodiment 3 (experiment three)

[0029] No adjusting shim 15 is added between the thrust bearing 14 and the thrust head 13, and an adjusting shim 12 is added on the end face side of the rigid coupling 11 between the water pump shaft 9 and the motor shaft 8, and the thickness of the shim 12 is adjusted according to the addition And the related dimensions of the device, calculate and predict the swing value and orientation that the pump shaft journal should have. Use dial gauge 3 23 to measure and calculate the maximum value and orientation of the swing at the journal of the water pump shaft, and compare and analyze with the calculated value.

Abstract

The invention provides a vertical type unit axis swing degree measuring and adjusting experimental device and experimental method. The experimental device comprises a supporting structure, a measuring and adjusting object and a measuring system. The measuring and adjusting object simulates a vertical type unit axis swing degree measuring structure, the axis swing degree can be set freely only by adding gaskets with the proper thickness to the position between a thrust bearing and a thrust block and the position between the thrust bearing and a rigid coupling, and the swing degree is applied to measurement, calculation, analysis and treatment. The axis swing degree is measured and calculated, the scraping value of the axis swing degree on the motor thrust bearing and the end face of the right coupling is calculated and treated, and consistency between the calculated scraping value and the direction of the swing degree and the thickness of the gaskets and the direction of the gaskets is verified. The swing degree is quite conveniently processed by removing the gaskets, a plurality of schemes can be test, calculated, analyzed and processed in a short time, and therefore a swing degree measuring tool can be used in a skilled mode, the swing degree measuring method can be mastered in a skilled mode, the measuring mechanism is known, and how to analyze and process the swing degree is learnt, so that the teaching quality is improved.

Description

technical field [0001] The invention relates to an experimental device and method for measuring and adjusting installation parameters of a vertical unit, in particular to an experimental device and an experimental method for measuring and adjusting the axis swing of a vertical unit. Background technique [0002] Vertical water turbine units and large vertical water pump units account for a large proportion of hydropower stations and pumping stations. The measurement and adjustment of the axis swing is a key link in the installation of new units and the regular or accidental overhaul of existing units, which is highly technical. If the technology is strong, the measurement and processing can be completed in only 2 to 3 days; on the contrary, it may not necessarily be adjusted in 2 to 3 weeks. If the swing is too large, the vibration of the unit will be aggravated, the guide bearing of the water pump will wear faster, and the guide bearing will be damaged, and accidents such ...
