Abstract
The utility model provides a voltage-stabilization electronic speed regulator comprising a generator voltage setting component, a voltage measuring component, a comparison component, an arithmetic component, a drive output component, an executive component, an adjusting parameter setting component, and a protection or limit component, which are connected successively to form a closed loop control system through combination. The executive component is an electromagnetic actuator and generator voltage is set by a voltage setting potentiometer. An oil injection rack of a high-pressure oil pump of an internal combustion engine is driven directly through the executive component, so that the supply quantity of fuel of the internal combustion engine can be controlled. Therefore, the revolving speed of a generator can be controlled through control of current magnitude of the electromagnetic actuator, and thus the effect of constant voltage can be achieved through repeated revolving speed adjustment.

Technical field
The utility model relates to a kind of voltage stabilizing electronic speed regulator.
Background technique
The voltage constant pressure adjust of traditional generator output is to regulate through the switch power voltage stabilizing by excitation field adjustment or output voltage, and traditional voltage regulating mode has the shortcomings such as volume is large, Heavy Weight, complex structure, manufacturing process complexity.
The model utility content
The technical problems to be solved in the utility model provides that a kind of volume is little, lightweight, simple in structure, the simple voltage stabilizing electronic speed regulator of manufacturing process.
For solving the problems of the technologies described above; the utility model adopts following technological scheme: have with lower member: generator voltage setting member, survey voltage component, comparing element, computing element, driver output element, executive component, accommodation coefficient setting member, protection or limiting element, above-mentioned parts are in turn connected to form a closed loop control system through combination.
Further, described executive component is electromagnetic actuator.
Further, generator voltage is set the potentiometer setting by voltage.
Voltage stabilizing electronic speed regulator of the present utility model, owing to directly drive the high pressure oil pump oil spout tooth bar of internal-combustion engine by executive component, thus the fuel feed of controlling combustion engine; Therefore, the size of current of control electromagnetic actuator gets final product the rotating speed of control engine, can reach by rotational speed regulation repeatedly the effect of constant voltage.
Description of drawings
Fig. 1 is the schematic diagram of the utility model voltage stabilizing electronic speed regulator.
Embodiment
In the present embodiment; with reference to Fig. 1; this voltage stabilizing electronic speed regulator; have with lower member: generator voltage setting member, survey voltage component, comparing element, computing element, driver output element, executive component, accommodation coefficient setting member, protection or limiting element, above-mentioned parts are in turn connected to form a closed loop control system through combination.Wherein, described executive component is electromagnetic actuator.Generator voltage is set potentiometer by voltage and is set.
Its working principle is: will set rated operational voltage and compare with the generator virtual voltage that the survey voltage component records, result relatively comprises two-part information: deviation " positive and negative " information and deviation amplitude information, the effect of deviation " positive and negative " information is, if the generator virtual voltage is greater than the operating voltage of setting, deviation is " bearing ", the voltage stabilizing electronic speed regulator will be exported " negative sense " control, reduce fuel feed by executive component, the explosive motor rotating speed decreases, and generator voltage decreases; If the generator virtual voltage is less than the operating voltage of setting, deviation is " just ", and the voltage stabilizing electronic speed regulator will be exported " forward " control, increase fuel feed by executive component, and the explosive motor rotating speed increases, and generator voltage increases; The effect of deviation amplitude information is: deviation amplitude is through the processing of arithmetical organ, determine the size of output controlled quentity controlled variable, namely increase or reduce what of fuel feed, in the situation that deviation amplitude is certain, the size of output controlled quentity controlled variable must be suitable, excessive or too smallly all can cause the explosive motor rotary speed unstabilization or not reach the adjusting speed accuracy requirement, i.e. the shakiness of output voltage or pressure regulation required precision, the size of output controlled quentity controlled variable is determined by " computing " link.
Described executive component is electromagnetic actuator, by the coil current of control electromagnetic actuator, namely can control the output displacement of electromagnetic actuator.Electromagnetic actuator directly drives the high pressure oil pump oil spout tooth bar of explosive motor, thus the fuel feed of control explosive motor; Therefore, the size of current of control electromagnetic actuator can be controlled the rotating speed of explosive motor.
The rated operational voltage of generator is set potentiometer by voltage and is set, and the virtual voltage of generator is got by sampling generator output voltage rectifier; This signal is converted to VDC through buffer circuit, and obtains the voltage deviation amount behind the voltage setting value; This deviation is behind PID regulator operation amplifier, change into the PWM current control mode, to the electromagnetic actuator output driving current, to change the outgoing position of electromagnetic actuator, drive explosive motor high pressure oil pump injection pump rack to the direction motion of voltage deviation, this closed loop control process guarantees generator stable operation under the voltage that sets that explosive motor drives.
Voltage stabilizing electronic speed regulator of the present utility model, owing to directly drive the high pressure oil pump oil spout tooth bar of internal-combustion engine by executive component, thus the fuel feed of controlling combustion engine; Therefore, the size of current of control electromagnetic actuator gets final product the rotating speed of control engine, can reach by rotational speed regulation repeatedly the effect of constant voltage.
Below the utility model is described in detail, the above only is the preferred embodiment of the utility model, when not limiting the utility model practical range, be allly to do impartial change and modify according to the application's scope, all should still belong in the utility model covering scope.
