Abstract

The invention relates to a pipeline delivery pump, which is suitable for the pipeline delivery of crude oil and natural gas and the sea water transportation in long distance in the field of desalination of sea water. The pump comprises a pump body, an impeller, a shaft, a left bearing device and a right bearing device; the impeller is arranged on the shaft in the pump body; two ends of the shaft extending out of the pump body are respectively provided with the left and right bearing devices which are connected with the pump body; the shaft end of the right bearing is connected with the outputshaft of a motor; two ends of the shaft are respectively provided with an axial hole; a shaft platform is arranged on the shafts of the first bearings of the left and right beating devices; and a circular groove is arranged in the middle of the shaft platform; and any part of the circumference of the circle groove is provided with a radial hole communicated with the axial hole. In the invention, the problems of difficult disassemble of the pipeline delivery pump bearing and unbalanced axial force are solved, and the bearing is extremely convenient and rapid to disassemble and maintain, a great amount of time is saved, and the work efficiency is greatly improved; and in addition, the impact of the axial force to the bearing is reduced and the service life of the bearing is improved by improving the structure of the bearing device.

Description

technical field

[0001] The invention relates to a pipeline delivery pump, in particular to a pipeline delivery pump used for pipeline delivery of crude oil and natural gas and seawater long-distance delivery in the field of seawater desalination. technical background

[0002] At present, there are many types of pumps, but according to different performance requirements and uses, their structures are also different. Pipeline transfer pump is one of them. It is mainly composed of pump body, impeller, shaft, bearing device, mechanical seal and other components. However, in the prior art, there are problems such as difficult disassembly of the bearing, unbalanced axial force, short service life of the bearing, and frequent replacement, which seriously affect the use of users. In order to solve this problem, our company has made major improvements to the shaft and bearing device of the pipeline pump, completely solving the above technical problems.
