Abstract
A kind of splashing disc device, belongs to centrifugation pump technical field.The device is covered outside pump shaft using annulate shaft set, and ring sleeve diameter and pump shaft take interference fit, and heating assembly, tight beam is fixed on pump shaft axis, then with positioning pin after cooling.Annulate shaft set lower section sets gradually link block, connecting rod and centrifugation；When pump shaft rotation, alternative splashing ring mechanism turns together, and centrifugation acts on the oil of oil storage pool, oil splashing is got up to be thrown on bearing chamber internal chamber wall, by trapped fuel groove, inflow need to lubricate place.Oil can be thrown on inner wall by specially designed concave structure in time, improved bearing service life, delayed to lead to bearing damage because of oil starvation, and bearing service life is improved or extend.Low level oil when because of oil shortcoming and can be splashed on bearing bearing service life can be improved by this device, delay to lead to bearing damage because of oil starvation, improve or extend bearing service life.
Description
Technical field
The utility model relates to a kind of splashing disc device, especially prevent the splashing for reducing bearing oil starvation because of oil level from getting rid of
Oil ring device belongs to centrifugation pump technical field.
Background technique
In use for some time, the rubbing surface of sealing can be because of the finish of axis, beating degree ring for the centrifugal pump of various types
The factors such as border grit pollution generate motility gap, the lubricating oil inside bearing housing can be flowed out by this gap cabinet with
Outside, there is oil leakage phenomenon.The safeguard measure that can be taken in operation is exactly to refuel in fuel tank, and in dynamic, fuel tank just has
A possibility that being likely to occur the state of super oil level, more increasing oil leak.The phenomenon that very likely occurring more leaking all the more, all the more more leaking.
Due to leaking or being lost the reduction of pump bearing box oil level, and bearing because oil starvation damages because of oil starvation in a short time (or
Cannot artificially feed in time causes).When unit is run, the phenomenon that oil or mist of oil in water pilot bearing run out of bearing oil groove, referred to as
Bearing gets rid of oil.This not only wastes lubricating oil, pollution environment, and unit is oily serious because getting rid of sometimes, and operation oil level decline is caused to cause
Oil level is too low, causes tile kilning.Sometimes unit is oily serious because getting rid of, and operation oil level decline is caused to cause oil level too low, causes tile kilning.
The consequence of oil leak: 1) equipment consumes one's energy concern thus daily, becomes the weak link on production line, is larger hidden trouble of equipment.
But hidden danger shutdown system maintenance and inspection thus, production can be delayed, cause environmental pollution, cost waste.2) if site environment has
In the case where biggish dust, oiling of uncapping, it is easy to dust be taken in fuel tank, and pollute lubricating oil, also result in bearing
, there is equipment breakdown in abnormal breakage.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of splashing disc device, to occur
When leakage or loss pump bearing box oil level reduce, oil is thrown on bearing chamber internal chamber wall by splashing ring mechanism, then by having
Groove is transported at bearing.
The technical solution adopted in the utility model is: a kind of splashing disc device, it is using pump shaft by the bearing at both ends
It supports, forms bearing chamber between bearing, splashing ring mechanism is set on the pump shaft, splashing ring mechanism includes annulate shaft set and the knot that splashes
Structure, annulate shaft set cover outside pump shaft, and annulate shaft set is fixed on pump shaft by positioning pin；The side that the splashing structure passes through link block
It is connected to annulate shaft to put on, the other side of link block is using connecting rod connection centrifugation；The bottom of the bearing chamber is equipped with bearing chamber
Oil storage pool, centrifugation act on the oil of bearing chamber oil storage pool, and bearing chamber internal chamber wall is equipped with trapped fuel groove, trapped fuel groove two sides
It extends at bearing.
The annulate shaft, which is put on, covers splashing structure equipped with 2-4.
Its principle is splashing ring mechanism to be fixed on axis with pin, when pumping when rotating under motor drives in pump shaft
Rotation drives lower and pump shaft synchronous rotary, and splashing ring 2 ~ 4 under the action of the centrifugal force on splashing ring are small in rotary course
The indoor low level oil of bearing can be splashed on bearing for the sub centrifugation of generation under the influence of centrifugal force of centrifugation or bearing chamber internal chamber wall
On, on bearing chamber internal chamber wall design there are two front and back flow direction trapped fuel groove, when splashing ring pump rotation when centrifuge blade from
The effect of mental and physical efforts is located to extend downwards, while rotating the trapped fuel groove that oil in bearing chamber oil storage pool can be thrown to bearing chamber internal chamber wall,
Oil can flow supply lubricating oil to bearing front and back end along trapped fuel groove.
The beneficial effects of the present invention are: the device is covered outside pump shaft using annulate shaft set, ring sleeve diameter and pump shaft were taken
Be full of cooperation, heating assembly, it is cooling after tight beam fixed on pump shaft axis, then with positioning pin.Annulate shaft set lower section set gradually link block,
Connecting rod and centrifugation；When pump shaft rotation, alternative splashing ring mechanism turns together, and centrifugation acts on the oil of oil storage pool, will
Oil splashes.Usually oil level is lower than the lower camber side of axis, will not oil leak when static.In centrifugal pump high speed rotation, leak
Or when loss pump bearing box oil level reduction, oil is thrown on bearing chamber internal chamber wall by splashing ring mechanism, pass through trapped fuel groove, stream
Place need to be lubricated by entering.Oil can be thrown on inner wall by specially designed concave structure in time, improve bearing service life, be delayed because lacking
Oil and lead to bearing damage, improve or extend bearing service life.The device uses centrifugal drying oil ring cooperation outside framework oil seal can be with
Accomplish that oil dripping does not leak high speed shaft in a dynamic state, thoroughly solves oil leak hidden danger, environmental pollution, shortens the problems such as bearing life.
Detailed description of the invention
Fig. 1 is a kind of structure chart of splashing disc device.
Fig. 2 is the sectional view of A-A in Fig. 1.
In figure: 1, bearing chamber, 1a, bearing chamber internal chamber wall, 2, bearing, 3, positioning pin, 4, pump shaft, 5, trapped fuel groove, 6, axis
Hold room oil storage pool, 7, splashing ring mechanism, 7a, annulate shaft set, 7b, link block, 7c, connecting rod, 7d, centrifugation.
Specific embodiment
Structure of the invention is described further referring to the drawings.
Figures 1 and 2 show that a kind of splashing disc device, it is supported using pump shaft 4 by the bearing 2 at both ends, bearing 2 it
Between form bearing chamber 1, splashing ring mechanism 7 is set on pump shaft 4, and splashing ring mechanism 7 includes annulate shaft set 7a and splashing structure, annulate shaft set
7a covers outside pump shaft 4, and annulate shaft set 7a is fixed on pump shaft 4 by positioning pin 3；Splashing structure is connected by the side of link block 7b
On annulate shaft set 7a, the other side of link block 7b is centrifuged sub- 7d using connecting rod 7c connection；The bottom of bearing chamber 1 is equipped with bearing chamber
