Abstract
The utility model provides a positive corrector of an oil jet pump of diesel engines, which is composed of a speed corrector case, a crown-shaped screw cap, a pretightening force adjusting sleeve, a stroke correcting and adjusting screw bolt, a top rod, a spring, an outer screw sleeve, and a hexagonal screw. Stroke of the top rod is controlled by the stroke correcting and adjusting screw bolt to adjust rotation speed of an oil pump. The positive corrector of an oil jet pump of diesel engines has the advantages of reasonable design, simple structure, easy manufacturing, small size, convenient and rapid adjustment, etc.
Description
The utility model relates to a kind of diesel engine part, specifically a kind of diesel injection pump speed regulator positive correction device.
The problem that the diesel injection pump speed regulator positive correction device of prior art in use exists is:
1. the variation of fuel injection correction pump plunger stroke will directly cause the change of the total oil mass limit value of calibration point distance, that is to say, need readjust declared working condition after the adjustment of correction operating mode, and want repeated multiple times, just can reach satisfied result, it is too high to exchange the technical requirement of trial work people.
2. the variation of fuel injection correction pump plunger stroke will directly cause correcting spring to give the change of tight power, thereby change and proofread and correct the rotating speed that works, and need the adjustment of frequent colony cushioning.
3. the correcting spring adjustment of the giving tight power heating examination of need disintegrating is gathered, and debugging technical ability requires high.
Thereby it is time-consuming to exist the diesel injection pump speed regulator to do in the positive correction work, deficiencies such as accuracy poor reliability.
The purpose of this utility model provides a kind of rapid, easy, technical less demanding, diesel injection pump speed regulator positive correction device of not needing frequent colony cushioning to adjust of debugging.
The purpose of this utility model realizes in the following manner, omoplate definite value mode in the correction push rod of corrector and the external thread sleeve employing, and by the tight power of giving of correcting spring, after the assurance nut check, the adjustment of proofreading and correct each parameter of operating mode does not influence the demarcation oil mass and places restrictions on a little.Employing is given tight power and is adjusted swivel nut and adjust and proofread and correct the rotating speed that works; Correction stroke is adjusted screw and is controlled correction stroke, thereby realizes the outside adjustment of Full Thread FT.
Accompanying drawing is the sectional structure schematic representation of diesel injection pump speed regulator positive correction device.
With reference to Figure of description positive corrector of disel engine oil jet pump of the present utility model is done Below explain.
Positive corrector of disel engine oil jet pump of the present utility model, its structure is by speed regulator Casing 11, crown nut 3, give that tight power is adjusted swivel nut 4, correction stroke is adjusted bolt 1, top Bar 9, spring 7, external thread sleeve 8, hex nut 10 consists of, and external thread sleeve 8 is fixed by screw thread On speed regulator casing 11, use then hex nut 10 standby tight, give tight power adjustment swivel nut 4 and will overlap Have the push rod 9 of spring 7 to be fixed in the middle of the external thread sleeve 8, outer locking nut 5 will give tight power and adjust spiral shell Cover 4 and external thread sleeve 8 locking positionings, correction stroke bolt 1 is fixed on by screw thread and gives tight power adjustment In the middle of the swivel nut 4, locking nut 2 is adjusted bolt 1 for tightly giving tight power adjustment swivel nut with correction stroke On 4.
Embodiment:
Its processing and fabricating of diesel injection pump speed regulator positive correction device of the present utility model is very simple and convenient, and manufacturing gets final product shown in the by specification accompanying drawing.Concrete using process is as follows:
1, declared working condition
The rising pump speed is adjusted high speed stop screw to oil mass and is demarcation oil mass CLV ceiling limit value to rated engine speed.To proofread and correct stroke adjustmenting screw and outwards screw out major part, and give tight power adjustment swivel nut and inwardly screw in, guarantee that correcting spring has certain tight power of giving; Then the inside screw-in of external thread sleeve is required the position to demarcating oil mass, be equipped with jack panel.
2, proofread and correct operating mode
Reduce pump speed, check whether proofread and correct the rotating speed that works meets the requirements, and give tight power by adjustment and adjust swivel nut and adjust and proofread and correct the rotating speed that works, inwardly screw in, the rotating speed that works reduces; Vice versa.Behind locking nut, continue to reduce rotating speed to proofreading and correct end point, adjust correction stroke by adjusting correction stroke adjustment bolt.Inwardly screw in, stroke reduces; Otherwise increase, adjusting finishes tightly gets final product locking nut fully.
Positive corrector of disel engine oil jet pump of the present utility model is compared with existing technology, tool Have reasonable in design, simple in structure, be easy to processing, volume is little, it is efficient and convenient to adjust, use peace The full characteristics such as reliable, thereby, have good value for applications.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
