Abstract
The invention discloses a sea-island filament PET and COPET metering pump switch interlocking circuit which comprises a COPET frequency changing circuit, a PET frequency changing circuit, a COPET motor starting circuit and a PET motor starting circuit connected between a live wire and a null wire. The COPET motor starting circuit comprises a first contactor which is connected in series with the PET motor starting circuit. A contactor in a COPET switch circuit is connected in series to a PET switch circuit, accordingly, if someone wants to open a PET metering pump, a switch of a COPET metering pump needs to be opened first, if the COPET metering pump stops operation, the PET metering pump stops operation, and therefore hidden danger caused by a PET single component is avoided.
Description
Technical field
The application belongs to spining technology field, particularly relates to the chain circuit of a kind of sea island filament PET, COPET volume pump switch.
