Abstract
The utility model relates to a deep-well centrifugal lubricating oil pump, which comprises a pump body, a pump cover and an impeller and is characterized in that: a pump shaft is arranged in a connecting pipe through a middle bearing component; one end of the pump shaft is provided with an upper bearing sleeve, and the other end of the pump shaft is arranged in the pump cover; an upper bearing is adjacent to a bearing gland; an outlet connecting pipe is provided with a first reflux oil pipe communicated with the pump cover and a second reflux oil pipe communicated with the bearing gland; and the bearing gland is provided with a third reflux oil pipe communicated with the connecting pipe. The lubricating oil pump has the advantages that: a structure consisting of three bearing sections is adopted and the pump is directly lubricated by conveying a liquid medium without any mechanical or packing seal, so that the pump is more convenient and rapid to maintain, insertion depth can be adjusted by changing the lengths of the pump shaft and the connecting pipe and the effect of plug and play is achieved; moreover, most components are welding parts which do not need sealing, have simple structures and are easy to process, maintain and replace.
Description
Technical field
The utility model belongs to the industrial pump technical field, particularly relates to the centrifugal lubricating oil pump of a kind of deep-wall type.
Background technique
The centrifugal lubricating oil pump lower bearing of common deep-wall type is generally sliding bearing, is directly installed on the pump housing, can be short of to some extent aspect the radial force of trunnion shaft, and particularly the radial force effect to axle strengthens under the operating mode of single channel, big flow.Upper bearing (metal) is a rolling bearing, be installed on the bearing bracket stand, bearing support is connected by bolt with the fuel tank upper plate, link span is connected by bolt with bearing support again, structure is complicated, and it is big to take up room, and bearing adopts grease lubrication, more common problem is to be easy to generate bearing heat, and then has shortened the working life of bearing.
Summary of the invention
The utility model provides a kind of simple in structure for solving the technical problem that exists in the known technology, can realize selflubricating, need not the centrifugal lubricating oil pump of deep-wall type of sealing configuration.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the centrifugal lubricating oil pump of deep-wall type, comprise the pump housing, pump cover, lower bearing, be installed on the impeller on the pump shaft, pump cover links to each other with upper bearing sleeve by connecting tube, upper bearing sleeve links to each other with hitch by bearing support, the side of the pump housing also is provided with discharge connection, it is characterized in that: described pump shaft is installed in the connecting tube by the intermediate bearing assembly, pump shaft one end is equipped with upper bearing sleeve by upper bearing (metal), and the pump shaft the other end is installed in the pump cover by lower bearing; Described upper bearing (metal) and bearing gland adjacency are provided with first backflow oil pipe that is communicated with pump cover and the second backflow oil pipe that is communicated with bearing gland on discharge connection, also be provided with the 3rd backflow oil pipe that is communicated with connecting tube on the bearing gland.
The utility model can also adopt following technological scheme: described intermediate bearing assembly is a sliding bearing.
Described lower bearing is a roller bearing.
Described lower bearing is a sliding bearing.
Advantage and the good effect that the utlity model has are: the centrifugal lubricating oil pump of this deep-wall type, and lower bearing can adopt rolling bearing or sliding bearing, and promptly rolling bearing and sliding bearing can exchange, thereby can choose suitable bearing according to different operating modes.The upper bearing (metal) body separates with bearing housing, is convenient to the installation and removal bearing; Link span and bearing support link together by bolt and fuel tank upper plate, and be simple in structure, good stability.Upper bearing (metal) adopts the selflubricating mode, and is promptly lubricated by institute's fed sheet of a media, makes the problem of upper bearing (metal) heating be well solved.Adopt three sections bearing structures and carry liquid medium directly lubricated, need not mechanical seal or packing seal, make that the maintenance of this pump is more convenient, can adjust insertion depth by change pump shaft and connecting tube length, thereby reach the effect of plug and play.Most of assembly adopts weldment, need not sealing, and is simple in structure, is easy to processing and maintain and replace.
