The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, oil extraction-generated waste water is handled the dosing pump controller, comprise an automatic branch road, be used for controlling dosing pump 11 operations automatically by setting-up time, automatically branch road comprises first time-delay relay 6, second time-delay relay 7, A.C. contactor 9, electrothermal relay 8, the first time-delay relay coil 6 is in series with change-over switch 4, be in parallel with the first time-delay relay coil 6 after the normally open contact 12 of the second time-delay relay coil 7 and first time-delay relay is in series, the normally closed interlock 16 of second time-delay relay is in parallel with the second time-delay relay coil 7 after being in series with ac contactor coil 9 and electrothermal relay 8; Manually branch road is used for forcing as required dosing pump 11 operations, and branch road is changed by change-over switch 4 with manual branch road automatically.Manually a route stop button 13, start button 14 are in series with change-over switch 4 and form.What be parallel with A.C. contactor at manual start button 14 two ends of branch road often opens auxiliary contact 15.
The course of work of the present utility model is: at the relevant index parameter of sewage disposal system water quality just often, change-over switch 4 is turned round automated location, breaker 1 closes a switch, when one or more inserts this circuit when external start signal 2, power supply indicator 5 redness are lighted, power supply is through overcurrent fuse 3, change-over switch 4 powers up for the first time-delay relay coil 6, the normally opened contact 12 of the first time-delay relay coil 6 is closed after T1 minute in enabling signal 2 one or more accesses, the readiness time that the T1 time cycle need be set for other associated device, dosing pump 11 does not move in during this, because normally-closed contact 16 closures of second time-delay relay 7, power supply makes A.C. contactor 9 coils get electric adhesive through overtemperature relay 8, startup contact 10 closures of A.C. contactor, make dosing pump 11 must establish the beginning startup by cable, the auxiliary contact 15 closed self-insurance operations of A.C. contactor 9 simultaneously, run signal lamp 17 greens are lighted.After T2 minute, the normal operation that is dosing pump 11 is after T2 minute, and the normally-closed contact 16 of second time-delay relay 7 disconnects, and makes dosing pump 11 disconnect out of service because of its ac contactor coil 9 dead electricity, run signal lamp 17 greens are extinguished, and finish the course of work of dosing pump 11.
Defective or think and produce when need force to control when water quality to dosing pump 11, change-over switch 4 is turned round manual position, breaker 1 closes a switch, when external start signal 2 one or more places in circuit, power supply indicator 5 redness are lighted, press start button 14, power supply forms the loop through overcurrent fuse 3, change-over switch 4, stop button 13, start button 14, ac contactor coil 9, electrothermal relay 8, make startup contact 10 closures of A.C. contactor, dosing pump 11 brings into operation, and run signal lamp 17 greens are lighted simultaneously.Press stop button 13, the circuit dead electricity, the startup contact 10 of A.C. contactor disconnects, and makes dosing pump 11 out of service, and run signal lamp 17 greens are extinguished, and finish the manual control procedure of dosing pump 11.Electrothermal relay 8 protection dosing pumps 11 are no more than rated current.
As shown in Figure 2, each parts of the utility model can be integrated in the casing, observe intuitively, operate.
The utility model and sewage mechanical filter programmable controller program operation switch board relating operation, one or more is the auxiliary normally opened contact that two covers stir backwash motor A.C. contactors external start signal 2, the auxiliary normally opened contact closure of its A.C. contactor when a cover filter stirs motor work, be equivalent to outside one tunnel enabling signal and insert this sequence circuit, setting 11 operations 8 minutes (T2) of stirring (T1) back startup in 5 minutes dosing pump stops then, effluent filter stirs and backwash total time generally is set at 15～20 minutes, treats that the next cycle arrival repeats above-mentioned dosing program.The working procedure of another set of filter is same as described above.Can start dosing pump in the random time during filter stirs backwash in the time of manually.
The utility model can insert two time-delay relays according to different enabling signals and controlled electric appliance actual needs, it is often opened or normally-closed contact carries out different combinations, sets working procedure flexibly.For example, behind the T1 that delays time after enabling signal inserts sometime, controlled electric appliance begins to start, and moves sometime behind the T2 out of service automatically; Again for example, enabling signal inserts the operation of last controlled electric appliance, and out of service behind the T1 that delays time sometime, another controlled electric appliance then begins to start, through out of service automatically behind the T2 sometime.Therefore the utility model also is applicable to other various simple associate device operation controls.
