Abstract
A low-speed spinning making up control system comprises a metering pump, a winding machine and a frequency converter. A second speed control signal is added to a frequency conversion control panel of the frequency converter; when the winding machine stops to send signals, a second speed of the frequency converter is triggered; and when the winding machine stops to send signals, the frequency converter is switched to a first speed automatically. Speeds of the frequency converter are switched by a multi-speed terminal S5. The frequency converter further comprises a metering pump running control terminal S1 with a start-stop function; under the circumstance that the S1 is on, the metering pump runs at a high speed when the S5 is on, and runs at a low speed when the S5 is off; and under the circumstance that the S1 is off, whether the S5 is on or off, the metering pumps dose not run. Stopping/starting signals of the winding machine are sent by a relay, and contacts of the relay are connected with the multi-speed terminal S5. By the aid of the low-speed spinning making up control system, when the winding machine is faulted and stopped, the speed of the metering pump is automatically controlled to be decreased by signals, and accordingly amount of silk waste is decreased greatly, and production cost is lowered for enterprises.
