Abstract

PURPOSE: To prevent the breakage of the apparatus due to the rush flow, by using the ramp-type signal which is generated simultaneously with the start of liquid supply pump for the flow rate control signal for a fixed period.
CONSTITUTION: With start of the liquid supply pump 17, the flow rate control valve 18 receives simultaneously the output 10A of the rush flow preventing device 10 and then opens gradually to start the supply of liquid to the centrifugal separator 20. On the other hand, the device 10 receives the liquid supply flow rate signal 12A as the input and then performs the operation 41 for the deviation to the target set value to supply the result of operation to the low value selecting circuit 42. At the circuit 42, a comparison is given between the input of the circuit 42 and the input of the ramp-type signal 43A which is supplied from the ramp-type signal generating circuit 43 and simultaneously with the start of the pump 17. And the lower input is selected to be delivered as the output 10A of the device 10 and then to control the divergence of the valve 18. In such way, the breakage of the apparatus due to the rush flow can be prevented.
