Description
Technical field
The utility model belongs to mechanized equipment field, more particularly to a kind of centripetal wheel oil pump.
Background technology
Under normal conditions, the oil pump of gas compressor is generally lubricated using bent axle as power, and at the end of bent axle
End installation gear pump, discharges after lubricating oil is drawn by vacuum chamber, plays lubricating action.
Since the field of conjugate action to gear may be due to matching defect and the caused abrasion that works long hours, between the field of conjugate action
Gap increases the supply capability that will substantially reduce oil pump, while higher using the failure rate of gear pump；On the other hand, gear pump exists
In the case of negative pressure, micro air leakage may occur for oil inlet pipe, and air will be preferentially entered in inlet line, make lubrication
The supply amount of oil reduces.Bearing to ensure bent axle can obtain continual and steady lubrication, it will usually the secondary grease pump of setting, not only
It increases manufacturing cost, and increases the space of installation and the complexity of pipeline.
Utility model content
In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of centripetal wheel oil pumps, use
In solve the problems, such as in the prior art gas compressor using gear pump high failure rate, complicated, cost is higher.
In order to achieve the above objects and other related objects, the utility model provides a kind of centripetal wheel oil pump, for lubricating axis
It holds and main shaft, the bearing matches with the main shaft, the centripetal wheel oil pump includes：Several centripetal tracks, it is described centripetal
Center of circle direction spiral of the track from the centripetal circumference for taking turns oil pump to the centripetal oil pump, in each centripetal track
The strainer for filtering lubricant oil is equipped with close to one end of the centripetal wheel oil pump circumference, in each centripetal track close to institute
The one end for stating the centripetal wheel oil pump center of circle is equipped with the plug screw for being used for lubricating oil described in water conservancy diversion.
Further, one end of the centripetal wheel oil pump circumference is in lubricating oil liquid level hereinafter, the centripetal wheel oil pump circle
One end of the heart is in more than lubricating oil liquid level.
Further, it is provided with nozzle on the plug screw, the opening direction of the nozzle is towards the bearing.
Further, the quantity of the centripetal track is 3-8, and is evenly distributed on the centripetal wheel oil pump towards described
The one side of bearing.
Further, the centripetal wheel oil pump is connect by trip bolt with the main shaft.
Further, the plug screw has U-lag close to the one end in the centripetal wheel oil pump center of circle.
As described above, the centripetal wheel oil pump of the utility model, has the advantages that：
1st, centripetal wheel oil pump is small, light-weight, convenient for I＆ M.
2nd, the reliability of centripetal wheel oil pump is high, even if when pump housing Oil Guide pipeline has fraction damage, nor affects on other U
The work of shape slot, U-lag work independently from each other, and the influence to lubrication is only to reduce lubricants capacity.
3rd, during centripetal wheel oil pump follows crank rotation, lubricating oil is pushed to by inertia and flows to bearing, as long as occurring to turn
It is dynamic to generate supply lubricating oil.And gear pump is in compressor start, due to being air in pipeline, air is easily between gear
Oil inlet direction is leaked back in gap, gear engagement place will be difficult to generate pressure.Or if when oil inlet pipe leaks, because of sky
The gas characteristic lighter than quality of lubrication oil, gear pump can suck more air from leakage hole in a manner of drawing and enter oil inlet pipe,
Be difficult to lubricating oil being drawn in oil supply system so as to gear pump, thus the structure of centripetal wheel oil pump it is simple, convenient for manufacture.
4th, at low cost, which is casting, and manufacturing procedure is few, and processing request is low, easy examination and maintenance, and repair is necessary
Property is small, and replacement process is simpler, and oil mass has certain controllability.
5th, failure rate is low, because being mounted in crankcase, by ectocine small (such as human accident, safety accident, low temperature phenomenon
Deng), and it is simple in structure, it is highly reliable.
