High-speed electromagnetic valve worked according to the different stages, need to be produced by driving voltage and drives electric current I and maintain electric current i.
Electric current I: electromagnetic valve is driven to overcome contained spring acting to open electromagnetic valve, when starting to drive electromagnetic valve to stretch spring
Time, required strength is bigger, and this design is to utilize big electric current to make electromagnetic valve open as early as possible, thus improves valve opening speed.
But, research finds, after driving voltage reaches to a certain degree, the rising of electric current can become very slow, and this has resulted in needs
Driving power supply that will be the biggest could produce big electric current, and during this, unnecessary energy can produce the biggest heat, causes efficiency
Reduce and the shortening in electromagnetic valve life-span.
Maintain electric current i: after electromagnetic valve is opened, it is only necessary to maintaining the spring in extended state, required strength is slightly smaller.
The invention is intended to, use twin voltage to drive, not only improve electromagnetic valve opening and closing frequency, also reduce energy consumption, prolong
Grow the life-span of electromagnetic valve.
In actual applications, the present invention high-speed electromagnetic valve driver circuit be about prior art is made that following two
Place improves.
Improvement 1,
In the valve opening stage, driving voltage VH changes a high level (T1 stage) and continuous print several PWM ripple (T2 stage) into.?
In the T1 stage, electric current can raise rapidly along with the rising of VH, when arriving T2, drives the electric current rate of climb can become very slow, as
Fruit now VH continues to keep high voltage, and electric current rises the least, and unnecessary ability is used for generating heat, and causes efficiency to reduce and the electromagnetic valve longevity
Life loss (it is found that original driving electric current meeting I is a little big than the driving electric current I1 after improving from oscillogram, but electromagnetism
The main energetic loss of valve just occurs at electric current during I1 is raised to I, and the present invention has avoided this stage).And now drive
The strength of electric magnet can overcome the spring within electromagnetic valve to do work, and is opened by electromagnetic valve.So, it is only necessary to several pwm pulses,
Keep driving electric current, just can open electromagnetic valve, improve efficiency, reduce heat release.
Improvement 2,
Employing twin voltage drives, and adds a driving voltage VL.The effect of VL is (T4 rank after closed electromagnetic valve
Section), continue as electromagnetic valve and one reference current is provided, when next electromagnetic valve opening signal is come interim, can improve rapidly and drive
Streaming current, thus more quickly open electromagnetic valve, reach the purpose of high speed opening and closing (owing to the reference current of VL offer compares
Little, energy loss and the infringement to electromagnetic valve are the lowest).When there is no valve opening signal for a long time, close VL, thus reach to improve energy
Effect and the effect of protection electromagnetic valve.
Have employed the high-speed electromagnetic valve driver circuit of this invention, in the valve opening stage, driving voltage VH first exports a high electricity
Flat, then output pwm pulse level, thus in the case of ensureing electromagnetic valve on-off action, it is to avoid heating, reduces energy and damages
Lose, improve high-speed electromagnetic valve service life, and then utilize driving voltage VL to export in order to keep high-speed electromagnetic valve in the valve closing stage
The reference voltage of reference current, thus meet the requirement of electromagnetic valve high speed opening and closing, raising electromagnetic valve opening and closing frequency, and the present invention
High-speed electromagnetic valve driver circuit, its simple in construction, with low cost, range of application is the most extensive.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still may be made that
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, specification and drawings is considered as illustrative
And it is nonrestrictive.
