Turning measurement device and method of swing degree of upper operating oil pipe of hydraulic blade all-adjustable water pump

Abstract

The invention provides a turning measurement device and calculation method of the swing degree of an upper operating oil pipe of a hydraulic blade all-adjustable water pump. The turning measurement device comprises a turning tool mounted at the upper part of a motor shaft coupling, and four dial indicators respectively positioned on the upper side surface of a thrust head of a motor thrust bearing, on the lower side surface of an outer oil pipe of an upper operating oil pipe, on the upper side surface of the outer oil pipe of the upper operating oil pipe and on the upper side surface of an inner oil pipe of the upper operating oil pipe; turning is carried out on a station building coupling layer of a pump station; the read numbers of the dial indicators are measured and recorded when the eight positions of I, II, III, IV, V, VI, VII, and VIII peripherally spaced by 45 degrees of the upper operating oil pipe are turned to the dial indicators; and the net swing degrees of three parts of the upper operating oil pipe are listed and calculated. The device can reduce the swing of the upper operating oil pipe and a sealing gap between the upper operating oil pipe and a mating hole copper sleeve of an oil head body, guarantees safe and reliable operation of a blade adjusting mechanism in the variable-working condition optimizing operation, the set starting, the stop working condition adjustment and the normal set operation process of the pump station when oil pressure keeps the blade angle, saves the operation and maintenance costs of the pump station, fully exerts the functions of engineering irrigation, drainage and water transfer of the pump station, and guarantees the safety of life and property of the people.

Description

technical field [0001] The invention relates to a special tool and method for installation and adjustment of hydraulic machinery, in particular to a device and method for measuring a hydraulic blade full-adjustment water pump for operating an oil pipe swing bar. Background technique [0002] The large vertical water pump hydraulic blade full adjustment mechanism has the advantages of large adjustment force, high adjustment accuracy and reliable adjustment action. However, the installation process of the hydraulic blade adjustment mechanism is complicated and requires high installation accuracy. In order to form sufficient pressure and ensure reliable blade adjustment, it is required that the average unilateral clearance between the inner and outer oil pipes of the upper operating oil pipe and the copper bushing of the oil receiver body is only 0.10mm (the design bilateral clearance is 0.20mm), while ensuring the operation The oil pipe does not hold back, which requires that...

AI Technical Summary

Problems solved by technology

[0004] The above method has the following problems: on the one hand, the upper operation oil pipe swing measured and calculated by using the special tool for cranking and the dial gauge is only the swing caused by the inclination of the upper operation oil pipe, and cannot reflect the swing caused by the dislocation of the upper operation oil pipe; On the one hand, factors such as the non-verticality of the upper operating oil pipe itself, the unevenness of the regulator base itself, and the radial clearance of the guide bearing of the special tool will cause measurement errors in the swing of the upper operating oil pipe

Therefore, it is easy to cause the remaining swing of the upper operation oil pipe to be too large

If the normal sealing gap is used, it is easy to cause the upper operation oil pipe and the copper sleeve of the matching hole of the oil receiver body to burn and damage

If the sealing gap is selected larger, it will not be able to form sufficient operating oil pressure, and the vane cannot be adjusted
