Abstract
The utility model relates to a vertical water pump impeller shaft radial supporting mechanism, in particular to an impeller shaft radial supporting mechanism used on a seawater desulfuration vertical diagonal flow pump, and belongs to the technical filed of water pump accessories. The structure comprises that four guide bearings are disposed on the upper side of a water pump impeller to provide radial support for a water pump main shaft, and is characterized in that a guide bearing is added on the lower side of the impeller to provide radial support for the main shaft, which makes both the lower side and the upper side of the impeller have supporting points, and forms a two-end supporting mode. The impeller is changed with the two-end supporting mode from a cantilevered structure in the utility model, which greatly enhances running stability of water pumps, and prolongs fault-free running time and overhauling period of equipment.
Description
Technical field
The utility model relates to a kind of vertical water pump impeller shaft radial support mechanism, and particularly a kind of impeller shaft radial support mechanism that is applied on the seawater desulphurization vertical diagonal flow pump belongs to water pump accessory technical field.
Background technique
The vertical water pump impeller shaft radial support mechanism of prior art mostly is cantilever structure, because of radial force effect in the water pump vane running, shockproofness is big, and impeller shaft cantilever end rigidity is relatively poor, cause the less stable of water pump operation, pump shaft and supporting element thereof and easily impaired influence equipment operation, the maintenance cost height.
The model utility content
The utility model technical issues that need to address provide a kind of vertical water pump impeller shaft radial support mechanism, by the improvement to the water pump radial support structure, improve the pump shaft rigidity, reduce shockproofness, prolong water pump working life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
A kind of vertical water pump impeller shaft radial support mechanism, comprise in its structure that layout four guide bearings in water pump vane top are set up a guide bearing to the main shaft radial support to water pump main shaft radial support below impeller, make the upper and lower strong point that all exists of impeller, form the two end supports form.
The further improvement of the technical solution of the utility model is:
The guide bearing that the impeller below is set up is arranged in the suction cone of water pump.
The bearing bracket and the suction cone of guide bearing are structure as a whole.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
This novel vertical water pump vane diameter of axle changes impeller into the two end supports form by cantilever structure to supporting mechanism, has greatly strengthened the stability of water pump operation, has prolonged equipment Mean time to failure and repair cycle.
