The utility model relates to a metering pump and spin finish pump external frequency converting device for chemical fiber filament spinning. The metering pump and spin finish pump external frequency converting device comprises multiple metering pumps and spin finish pumps, and is characterized by further comprising a three-phase electricity input end, a first PLC, a second PLC, a metering pump frequency converter and a spin finish pump frequency converter. The first PLC is connected with the control end of the metering pump frequency converter and the control end of the spin finish pump frequency converter, each metering pump is connected with the output end of the metering pump frequency converter through a trigger, and each spin finish pump is connected with the output end of the spin finish pump frequency converter through a trigger. The three-phase electricity input end supplies power to the metering pump frequency converter, the spin finish pump frequency converter and a transformer, the transformer supplies power to the second PLC through a 24-V power circuit, and the second PLC is connected with a touch screen, a first trigger and a cooling fan. Complex manual wiring can be replaced, and reliability and safety are enhanced.
