Specific embodiment 2
As shown in Figure 1, Figure 2 and Figure 4, identical with embodiment 1.Different places is, drive circuit 8 is different, and described drive circuit comprises toggle switch K2, K switch 3, K switch 4, closes K1 by general formula by opening up, K switch 5, K switch 6, K switch 7, solenoid 6, storage capacitor C2, storage capacitor C3, storage capacitor C4, K switch 5, K switch 6 is linked switch, and drive circuit 8 is connected with power supply, and a pole of power supply is connected with K switch 1, the other end and storage capacitor C2, storage capacitor C3 is connected with the also tie-point of storage capacitor C4, storage capacitor C2, storage capacitor C3 and storage capacitor C4 respectively with K switch 2, K switch 3, K switch 4 is connected, K switch 2, K switch 3, connect with solenoid 6 again after the parallel connection of K switch 4 other end, wherein, one end of K switch 6 is connected on the contact of K switch 1 and solenoid 6 connection, the other end is connected on the contact of K switch 4 and storage capacitor C4 connection, one end of K switch 7 is connected on the contact of K switch 1 and solenoid 6 connection, and the other end is connected with the also tie-point (i.e. the contact of power supply V) of storage capacitor C.Power supply V is civil power.Storage capacitor C2, storage capacitor C3 and storage capacitor C4 are 200 ~ 300 microfarads; when the pattern of this three storage capacitor C parallel connection goes for powerful equipment to avoid transient pulse voltage/current excessive; to the requirement on devices of driver element too high (decomposing the load capacity of single metal-oxide-semiconductor field effect transistor); and the available field effect transistor compared with low parameter is in circuit, is conducive to scale and arranges and can effectively reduce costs.
It should be noted that, in actual sample, K switch 1, K switch 5, K switch 6, K switch 7 are for open in usual by opening up pass, K switch 2, K switch 3 and K switch 4 is toggle switch, under normality (initial condition), be set to conducting state, K switch 1, K switch 5, K switch 6, K switch 7 are because being Push switch open in usual, and normality (initial state) is off-state.K switch 2, K switch 3 and K switch 4 are set to conducting, close K1 conducting, charging (power supply connection) by opening up, and dynamic iron core 7 forward moves; First time electric discharge: K switch 3, K switch 4 are disconnected, K switch 2 keeping conducting, closing K7 conducting by opening up, dynamic iron core 7 oppositely movement; Second time electric discharge: K4 closes, and K switch 2, K switch 3 disconnect, K switch 1, K switch 7 maintain and disconnect, and close K5 K switch 6 (K5, K6 are interlock) by opening up, dynamic iron core 7 forward moves; Third time is when discharging: K switch 1, K switch 5, K switch 6 maintain and disconnect, and K switch 2, K switch 4 disconnect, K switch 3 conducting, closes K7 conducting by opening up, dynamic iron core 7 oppositely movement.
Owing to have employed the storage capacitor C of series connection, for solenoid reverse charging provides energy, serve the effect of blocking-up (direct current) power supply simultaneously.Still be articulated on electrical network even if the charging of such device is over, only consume be storage capacitor sew power consumption and field effect transistor sew power consumption.Even therefore low-voltage (as AC24V) design, is applied to AC220V situation and still can normally runs (rechargeable energy is constant, is only to have shortened in the charging interval).Therefore it has had the adaptive capacity for supply voltage greatly concurrently, does not worry that overcurrent burns the problem of coil.
For being adapted to a little bigger pump of power and compressor class, devise the another kind of form of drive circuit 8: repetition pulse is powered, force dynamic iron core reciprocating motion, due to required storage capacitor C comparatively large (hundreds of microfarad), the transient voltage of formation and electric current are all very large.Suitable coupling solenoid parameter and hard magnetic body magnetic field intensity, storage capacitor numerical value, dividing storage capacitor C by 2-3 parallel running as shown in Figure 4 can be designed: switch on power, charged in parallel, when power supply is in another level (be equivalent to power-off--the square pulse interval) period, it is controlled automatically, respectively 2-3 electric discharge is carried out to solenoid, so, can be popular to field effect transistor switch pipe, thus reduce costs.Switchette is used to simulate metal-oxide-semiconductor field effect transistor in sample: K switch 1, K switch 5, K switch 6, K switch 7 are by opening up pass, and K switch 5, K switch 6 link, and K switch 2, K switch 3, K switch 4 are small-sized toggle switch, carry out dry run.In actual application, can be connected with K switch 1, K switch 2, K switch 3, K switch 4, K switch 5, K switch 6, K switch 7 by single-chip microcomputer or other controller, in practical application, K switch 1, K2, K3, K4, K5, K6, K7 selection metal-oxide-semiconductor field effect transistor are replaced, then carry out logic by single-chip microcomputer automatically to control to close/open, realize automatically controlling.
