Description of drawings
Fig. 1 is the utility model schematic diagram.
Wherein 1-storage vat, 2-magnetic drive pump, 3-filling exit, 4-frequency converter, 5-potential device, 6-control circuit.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to Fig. 1, magnetic drive pump 2 and the filling exit 3 of the storage vat 1 that connects successively through pipeline, frequency converter 4 controls, described frequency converter 5 power supplies are connected with frequency converter 4 through K switch, the control circuit 6 of described frequency converter 4 comprises respectively first loop and the second servo loop in parallel with the converter power supply two ends of two ends, and the tertiary circuit of connecting with control signal wire A, the B end of frequency converter 4; Described the first loop comprises successively the normally closed contact of control button OA, the second ticker SA2 of series connection and the coil of very first time relay SA1, the described very first time continue the first open contact of electrical equipment SA1 and the second time relay SA2 often to drive the time-delay break contact in parallel with the two ends of start button OA; Described second servo loop comprises the normally closed time-delay break contact of often opening time closing contact, the second time relay SA2 of the very first time relay SA1 that connects successively and the coil of the second time relay SA2, and the open contact of described the second time relay SA2 is in parallel with the two ends of often opening the time closing contact of very first time relay SA1; The second open contact of described very first time relay SA1 is connected with control signal wire A, the B of frequency converter 4 end.Described frequency converter 4 also is connected with potential device 5.
Principle of work:
Step (1): during can, the power turn-on K switch, press control button OA, electric current makes the coil of very first time relay SA1 get electric work through the normally closed contact of control button OA, the second time relay, the second ticker SA2, so that the very first time is continued the first open contact of electrical equipment SA1 is closed and the second open contact is closed, control frequency converter 4 makes magnetic drive pump 2 begin the can work, liquid is by storage vat 1, magnetic drive pump 2, carry out can through filling exit 3;
Step (2): when magnetic drive pump 2 is worked to setting-up time (can to set amount time), very first time relay SA1 often opens the time closing of time closing contact; Then electric current makes the coil of the second time relay SA2 get electric work through the normally closed time-delay break contact of often opening time closing contact, the second time relay SA2 of very first time relay SA1, the normally closed contact of the open contact closure of the second time relay SA2, the second ticker SA2 that connects with the coil of very first time relay SA1 disconnects, the coil blackout of very first time relay SA1, so that disconnect with the second open contact of very first time relay SA1, control frequency converter 4 makes magnetic drive pump 2 stop can work;
Step (3): when magnetic drive pump 2 quits work to setting-up time, the normally closed time-delay break contact time-delay of the second time relay SA2 disconnects, the coil blackout of the second time relay SA2, the normally closed contact closure of the second ticker SA2, the open contact of the second time relay SA2 are disconnected, the coil of very first time relay SA1 gets electric, enters step (1) periodical duty.
Can be by regulator potentiometer 5 to adapt to different pressures liquid, by can control amount and the pitch time of can to the adjusting of two time relay SA1, SA2.
