Abstract
The utility model diskloses a centrifuge emergency brake circuit structure. The structure comprises a power supply, a breaker and a fuse both arranged on the output end of the power supply, a frequency conversion driver circuit controlled by the power supply, and a main motor circuit driven by the frequency conversion driver circuit. A stop button switch, a start button switch and a relay KA1 are sequentially arranged between the output end of the fuse and the frequency conversion driver circuit. A sudden stop pedal switch and a relay KA2 are further arranged between the output end of the fuse and the frequency conversion driver circuit. The relay KA1 and the relay KA2 are arranged in a parallel way. The relay KA1 is connected with an FDW terminal of the frequency conversion driver circuit. The relay KA2 is connected with an S1 terminal of the frequency conversion driver circuit. The structure can make the frequency conversion driver circuit rapidly diskonnected and effectively protect a centrifuge and a frequency converter.

Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of centrifuge emergency brake circuit structure, to improve centrifuge safety in operation.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of centrifuge emergency brake circuit structure, comprise power supply, be arranged on circuit breaker and the fuse of described power output end, and the variable frequency drives circuit of being controlled by described power supply, and by the main motor circuit of described variable frequency drives drives, between the output of described fuse and variable frequency drives circuit, be disposed with stop button switch, start button switch and relay K A1, between the output of described fuse and variable frequency drives circuit, be also provided with anxious stop pedal switch and relay K A2, described relay K A1 and relay K A2 are arranged in parallel, described relay K A1 is connected with the FDW terminal of described variable frequency drives circuit, described relay K A2 is connected with the S1 terminal of described variable frequency drives circuit.
Pass through technique scheme, a kind of centrifuge emergency brake circuit structure that the utility model provides, it is by arranging relay K A1 in parallel and relay K A2, and by the FDW terminal of relay K A1 connection variable frequency drives circuit, relay K A2 connects the S1 terminal of variable frequency drives circuit, when centrifuge galloping and when may cause danger, step on the anxious pedal brake that stops, suddenly stopping pedal switch connects, relay K A2 control relay KA1 stops, and stop signal is delivered to variable frequency drives circuit by S1 terminal, thereby disconnect rapidly variable frequency drives circuit, effectively protect centrifuge and frequency converter.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.
Fig. 1 is the disclosed a kind of centrifuge emergency brake circuit structural representation of embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 1, the utility model comprises power supply, be arranged on circuit breaker Q F and the fuse FU of power output end, and the variable frequency drives circuit VF being controlled by power supply, and the main motor circuit being driven by variable frequency drives circuit VF, between the output of fuse FU and variable frequency drives circuit VF, be disposed with stop button switch AT, start button switch AQ and relay K A1, between the output of fuse FU and variable frequency drives circuit VF, be also provided with anxious stop pedal switch JXK and relay K A2, relay K A1 and relay K A2 are arranged in parallel, relay K A1 is connected with the FDW terminal of variable frequency drives circuit VF, relay K A2 is connected with the S1 terminal of variable frequency drives circuit VF.
A kind of centrifuge emergency brake circuit structure that the utility model provides, it is by arranging relay K A1 in parallel and relay K A2, and by the FDW terminal of relay K A1 connection variable frequency drives circuit VF, relay K A2 connects the S1 terminal of variable frequency drives circuit VF: when equipment normally moves, relay K A1 controls the operation of main motor circuit/stop, and the FDW terminal of variable frequency drives circuit VF is run signal terminal; When centrifuge galloping and when may cause danger; step on the anxious pedal brake that stops; suddenly stopping pedal switch JXK connects; relay K A2 control relay KA1 stops; and stop signal is delivered to variable frequency drives circuit VF by S1 terminal; thereby disconnect rapidly variable frequency drives circuit VF, effectively protected centrifuge and frequency converter.
To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.
