Electromotor can be reduced cannot start because what tooth bar clamping stagnation led to；Reduce starting time, increase service life of aeroengine.
The purpose of this utility model is achieved through the following technical solutions.
A kind of anti-clamping stagnation diesel engine electronic speed setting controller, including anti-clamping stagnation controller, executor, decision circuitry, rotating speed
Feedback circuit, oil mass loaded circuit,
Described anti-clamping stagnation controller, including shake control circuit, described shake control circuit is connected with executor；
Described shake control circuit, applies electric current in engine start to executor, makes executor control injection pump to draw
Bar drives injection pump plunger to move back and forth；
Described decision circuitry, for relatively more default engine speed and actual engine speed, judges whether to start accordingly
Oil mass loaded circuit；
Described speed feedback circuit, is connected with decision circuitry, and the actual engine speed recording is fed back to decision circuitry；
Described oil mass loaded circuit, is connected with decision circuitry and executor, and according to the control signal of decision circuitry, control is held
Row device takes injection pump motion to, adjusts injection pump supply, controls the rotating speed of electromotor.
Described executor is preferably electromagnetic actuator.
The utility model has the advantage of：
This utility model is that a kind of electron speed regulator preventing injection pump ratch clamping stagnation adjusting oil pump exploitation for electricity controls
Device, shakes control circuit by increasing anti-clamping stagnation in electron speed regulator controller, and electricity can be avoided to adjust the engine start of oil pump
When can not start or difficulty in starting because of oil pump ratch clamping stagnation, the electromotor leading to.This utility model increased engine reliable
Property, improve the service life that electricity adjusts injection pump, reduce fault rate.
Brief description
By reading the detailed description of hereafter preferred implementation, various other advantages and benefit are common for this area
Technical staff will be clear from understanding.Accompanying drawing is only used for illustrating the purpose of preferred implementation, and is not considered as to this practicality
New restriction.And in whole accompanying drawing, it is denoted by the same reference numerals identical part.In the accompanying drawings：
Accompanying drawing 1 is anti-clamping stagnation Digital Governor for Diesel Engine controller fundamental diagram；
Accompanying drawing 2 controls pull bar to drive plunger to carry out the schematic diagram of pump oil for executor.
Wherein：1. oil spout pump rod, 2. injection pump plunger.
Specific embodiment
It is more fully described the illustrative embodiments of the disclosure below with reference to accompanying drawings.Although showing this public affairs in accompanying drawing
The illustrative embodiments opened are it being understood, however, that may be realized in various forms the disclosure and the reality that should not illustrated here
The mode of applying is limited.On the contrary, these embodiments are provided to be able to be best understood from the disclosure, and can be by this public affairs
What the scope opened was complete conveys to those skilled in the art.
According to embodiment of the present utility model, as shown in Figure 1 and Figure 2, a kind of anti-clamping stagnation diesel engine electronic speed regulating control
Device, including anti-clamping stagnation controller, executor, decision circuitry, speed feedback circuit, oil mass loaded circuit, described anti-clamping stagnation controls
Device, including shake control circuit, described shake control circuit is connected with executor；Described shake control circuit, applies to executor
Plus short-time current, make executor control oil spout pump rod to drive injection pump plunger to move back and forth；Described decision circuitry, is used for comparing
Default engine speed and actual engine speed, judge whether to start oil mass loaded circuit accordingly；Described speed feedback circuit,
It is connected with decision circuitry, the actual engine speed recording is fed back to decision circuitry；Described oil mass loaded circuit, with judgement electricity
Road is connected with executor, according to the control signal of decision circuitry, controls executor to take injection pump motion to, adjusts injection pump supply
Amount, controls the rotating speed of electromotor.Described executor is preferably electromagnetic actuator.
Operation principle of the present utility model：Because of oil pump poorly sealed intrusion dust at oil spout pump rod, during engine long
Between not actuated aeronautic ATE is sticky etc. that factor causes pull bar stiction fQuietIncrease.Power F when the not jittered streaming current of executorOpen＜
fQuietWhen, oil spout pump rod clamping stagnation can not normally start.
Anti- clamping stagnation controller, by applying of short duration high current when starting, makes executor during startup have enough Li Laibao
Card：FTremble＞ ＞ fQuiet.After shaking back and forth, because kinetic force of friction is f less than stictionQuiet＞ fDynamic.Injection pump is starting fuel-flow control
Under will normally run.
This utility model increases shake control circuit in the controller internal circuit of electron speed regulator.Open in activate switch
Qi Shi, applies of short duration high current to electromagnetic actuator, first shakes back and forth for several times when controlling executor with respect to normal startup.Apply
High current make executor produce to exceed moment needed for static friction.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model answers institute
State and be defined by scope of the claims.
