Abstract
An RQVK speed governor with a full-load power compensating function comprises a speed governing handle, a limit piece, a plunger pair and a limiter, wherein the limit piece is in transmission connection with the speed governing handle, the plunger pair is in transmission connection with the limit piece, and the limiter limits the maximum bidirectional stroke of the limit piece. The RQVK governor is characterized in that compensating pieces made of low-abrasion-degree materials are arranged on the limit piece and at positions contacting with the limiter, and both the limit piece and the limiter are made of high-abrasion-degree materials. The RQVK speed governor with the full-load power compensating function has the advantages that decrease of oil supply quantity of the plunger pair at quick-abrasion stage can be compensated, and output power of an engine is guaranteed to be identical with a design value.
Description
Technical field
The present invention relates to a kind of speed regulator, relate in particular to a kind of RQVK speed regulator with the full load power compensate function.
Background technique
The schematic diagram of RQVK speed regulator as shown in Figure 1, the driver comes the motion of transmission banking stop by the operation speed-regulating handle, banking stop rotates by the gear on the fuel-flow control bar driving ram pair of band tooth bar again, driving plunger when gear rotates takes place circumferentially to rotate, thereby the oilhole on the change plunger and the relation of the position between the plunger bushing finally play the effect that the trunk piston set oil pump capacity is regulated; Banking stop is except playing the driving ram pair, and banking stop also cooperates with snubber, and the adjustable extent of speed regulator is limited, and its restriction is realized by the physics block between banking stop and the snubber;
Existing trunk piston set technology is very ripe, its material and preparation process relative fixed, after new trunk piston set comes into operation, normal wear must appear, and when just having begun to wear and tear, the rate of wear very fast (this stage definitions is quick wear stage), wait to wear up to a certain degree after, the rate of wear slows down again, scraps (do not consider situation that miscellaneous part scraps under) until wearing up to trunk piston set; Because the existence of wear stage fast causes the circumferential stroke of trunk piston set to shorten, its actual fuel delivery is lower than design load, thereby causes engine power also corresponding on the low side.
Summary of the invention
At the problem in the background technique, the present invention proposes a kind of RQVK speed regulator with the full load power compensate function, the banking stop that comprises speed-regulating handle, is in transmission connection with speed-regulating handle, the trunk piston set that is in transmission connection with banking stop and the snubber that the two-way range of banking stop is limited, its improvement is: on the described banking stop, with snubber position contacting place be provided with compensating plate, because the existence of compensating plate, the stroke of banking stop and trunk piston set is all relative less when just beginning; Compensating plate adopts the material of low abrasion resistance to make, and banking stop and snubber all adopt the material of high abrasion degree to make;
Principle of the present invention is: after new equipment put into operation, because the abrasion resistance of compensating plate is lower, compensating plate and trunk piston set were worn and torn synchronously, and along with the progressively wearing and tearing of compensating plate, the stroke of banking stop progressively increases, thereby the stroke of trunk piston set is also progressively increased; After pad wear to be compensated was intact, banking stop directly contacted with snubber, and the stroke of banking stop and trunk piston set also stops to change; In this programme, by at banking stop compensating plate being set, thereby make banking stop before putting into operation, possess certain wear allowance, along with gradually reducing of wear allowance, the stroke of banking stop progressively increases, and the circumferential stroke of trunk piston set also correspondingly progressively increases, and reduces thereby offset the circumferential stroke that causes because of the trunk piston set wearing and tearing, the fuel delivery of trunk piston set is remained near the design load substantially, thereby guarantee that engine output meets design load.
Preferably, described compensating plate adopts the metallic material of hardness below HRC40 to make, and described snubber and banking stop all adopt the metallic material of hardness more than HRC50 to make.Concrete material, the size of compensating plate can be determined in the following way: earlier trunk piston set is carried out wear test, obtain it in the stroke reduction data of quick wear stage, be ready for use on the material of making compensating plate by aligning then and carry out wear test, rationally determine concrete material and the size of compensating plate, those skilled in the art should be understood that, also there are certain proportion relation in the stroke of trunk piston set and the stroke of banking stop, and this proportionate relationship can be by carrying out length measuring to actual part and simple computation is known.Implement for the ease of those skilled in the art, the invention also discloses following concrete material: compensating plate can be selected low-durometer material such as general 20# steel, 20Cr, 35# steel, 45# steel, perhaps use middle-carbon steel such as general 35# steel, 45# steel with hardness quenching and tempering below HRC40; Banking stop and snubber can select low carbon steel such as 20# steel, 20Cr to carry out quenching in contact segment after the Carburization Treatment, and its hardness is reached more than the HRC50.
Preferably, described compensating plate or be pasted on the banking stop by adhesive means perhaps adopts welding manner to be welded on the banking stop.
Useful technique effect of the present invention is: can descend to the fuel delivery that the quick wear stage of plunger synetion causes compensates, and guarantees that engine output is identical with design load.

The corresponding parts of each mark are respectively among the figure: speed-regulating handle 1, banking stop 2, compensating plate 3, high speed snubber 4, low speed snubber 5(indication snubber of the present invention comprise high speed snubber and low speed snubber), fuel-flow control bar 6, trunk piston set 7, be used for the secondary gear 8, the flyball assembly 9 that circumferentially rotate done of driving ram.
Embodiment
A kind of RQVK speed regulator with the full load power compensate function, the banking stop 2 that comprises speed-regulating handle 1, is in transmission connection with speed-regulating handle 1, the trunk piston set that is in transmission connection with banking stop 2 and the snubber that banking stop 2 two-way ranges are limited, its improvement is: on the described banking stop 2, with snubber position contacting place be provided with compensating plate 3, because the existence of compensating plate 3, the stroke of banking stop 2 and trunk piston set all relative less (for the situation after compensating plate 3 has worn and torn) when just beginning; Compensating plate 3 adopts the material of low abrasion resistance to make, and banking stop 2 and snubber all adopt the material of high abrasion degree to make;
After new equipment put into operation, compensating plate 3 and trunk piston set were worn and torn synchronously, and along with the progressively wearing and tearing of compensating plate 3, the stroke of banking stop 2 and trunk piston set all progressively increases; After having worn and torn for to be compensated 3, banking stop 2 directly contacts with snubber, and the stroke of banking stop 2 and trunk piston set also stops to change; In the aforementioned schemes, the trunk piston set fuel feeding decrease that the stroke increase of banking stop 2 is used for the normal wear of plunger synetion is caused compensates.
Further, described compensating plate 3 adopts the metallic material of hardness below HRC40 to make, and described snubber and banking stop 2 all adopt the metallic material of hardness more than HRC50 to make.
Further, described compensating plate 3 or be pasted on the banking stop 2 by adhesive means perhaps adopts welding manner to be welded on the banking stop 2.
