Description
Technical field
The present invention relates to a kind of vertical type pump bearing oil lubrication structure, belong to mechanical fluid field.
Background technique
Pump in service to connect the bearing of pump shaft carry out necessary lubricated be mainly in order to reduce friction power loss, play the effects such as cooling, dustproof, antirust and absorbing simultaneously.The means of bearing lubrication are generally oil lubrication and grease lubrication.Although wherein grease lubrication can play the effect that reduces friction power loss, but cannot carry out cooling to bearing, the pump in high temperature industrial and mineral to long-time running especially, adopts grease lubrication easily to make to be attached to after lubricating grease on bearing dissolves under high temperature condition and drops, and causes bearing because de-oiling damages.
For vertical pump, its pump shaft connection structure comprises upper and lower two groups of bearings, because its top connection bearing and bottom connection bearing are at a distance of higher, if employing oil lubrication conventionally need to be by lubricant oil submergence upper bearing (metal) ball position, can waste in a large number lubricant oil, therefore to be generally lower bearing be oil lubrication to the lubricating structure of vertical pump, and upper bearing is grease lubrication, so just causes vertical pump to be difficult to prolonged application under the working environment of high temperature.
Summary of the invention
The object of the invention is to be difficult to the problem of prolonged application under the working environment of high temperature in order to solve vertical pump, and a kind of vertical type pump bearing oil lubrication structure proposing.
The object of the invention is to be achieved through the following technical solutions:
A kind of vertical type pump bearing oil lubrication structure of the present invention, comprises oil thrower wheel, bearing housing, rolling bearing, oil guide pipe;
Oil thrower wheel is cirque structure, and the outer, lower end of oil thrower wheel extends outward the blade of circle distribution;
The top and bottom of pump shaft are connected with bearing housing with lower rolling bearing by upper rolling bearing respectively, in bearing housing, lower rolling bearing bottom is provided with shoe cream room, oil thrower wheel is fixed by a pin to the pump shaft sidewall of shoe cream room position, in bearing housing, the sidewall of shoe cream room position has oil outlet, in bearing housing, the sidewall of upper rolling bearing position has oil inlet hole, and the oil outlet of bearing housing and oil inlet hole are by oil guide pipe UNICOM.
Wherein, the lubricant oil pasta in bearing housing shoe cream room is higher than 1/2 place of lower rolling bearing, and the oil outlet position of opening of bearing housing and the leaf position on oil thrower wheel align, and the oil inlet hole position of opening of bearing housing is higher than 1/2 of upper rolling bearing.
Upper rolling bearing lower end is by oil baffle and pump shaft axial limiting, and the outer of oil baffle and bearing housing inwall Spielpassung, make the outer of oil baffle and bearing housing inwall form throttle structure.
Working procedure:
During vertical pump work, oil thrower wheel, with pump shaft High Rotation Speed, drives the lubricant oil High Rotation Speed in shoe cream room and lower rolling bearing is carried out to oil lubrication; Meanwhile, under the centrifugal force pulls effect producing at oil thrower wheel High Rotation Speed, lubricant oil enters the installation position of rolling bearing through oil guide pipe from the oil inlet hole of bearing housing upper end from the oil outlet of bearing housing lower end, and upper rolling bearing is carried out to oil lubrication; Lubricant oil is subject to the throttling action of oil baffle when the installation position of upper rolling bearing flows downward, and forms the oil reservoirs of certain altitude in the installation position of upper rolling bearing; Lubricant oil is back to the shoe cream room of bearing housing lower end under Action of Gravity Field from oil baffle lateral, realizes circulating of lubricant oil.
Beneficial effect
The present invention has realized the vertical pump of a small amount of lubricant oil and has carried out oil lubrication, has expanded the serviceability temperature scope of pump, the working life of having improved pump.The present invention is simple, practical, fabricating cost is low, and part is easy to process, has important use value.
