Problems solved by technology

[0004] The purpose of the present invention is to overcome that there is no experimental device for measuring and adjusting the axis swing of the vertical unit at present, and it is necessary to go to the equipment site to learn the method for measuring and adjusting the axis swing of the vertical unit. Because the learning time cannot be guaranteed, the learning effect is poor, resulting in vertical units. Disadvantages of poor axis swing measurement technology and low adjustment accuracy

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 an experimental device and an experimental method for measuring and adjusting the axis swing of a vertical unit. The experimental device includes three parts: support structure, measurement adjustment object and measurement system. The object of measurement and adjustment is the simulation of the measuring structure of the axis swing of the vertical unit. As long as a gasket of appropriate thickness is added at an appropriate position between the thrust bearing and the thrust head and between the rigid coupling, the axis swing can be set freely for measurement, Computing, analysis and processing. Measure and calculate the axis swing, calculate the scraping value of the axis swing at the thrust bearing of the motor and the end face of the rigid coupling, and verify the consistency of the calculated scraping value and its orientation with the thickness and orientation of the added gasket. Wobble is easily handled by removing the shim. In a short time, multiple scenarios can be tested, calculated, analyzed and processed. Therefore, you can skillfully use the swing measurement tool, master the swing measurement method, understand the measurement mechanism, and learn how to analyze and process the swing, so as to improve the teaching quality.

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 ...
