Abstract

Un dispositivo di protezione di pompa di circolazione in una caldaia comprende sensori di temperatura e di pressione disposti in un tubo di aspirazione di una pompa di circolazione, un circuito convertitore analogico-digitale collegato ai sensori attraverso conduttori isolati, ed un microelaboratore avente estremità di ingresso collegate ai sensori ed una estremità di uscita collegata elettricamente al circuito convertitore analogico-digitale. Il rumore della cavitazione generato dal vapore viene prodotto parzialmente dalla pressione dell'acqua inferiore alla tensione di vapore dell'acqua e quando la pompa di circolazione marcia a vuoto a causa di un flusso insufficiente di acqua di riscaldamento nel sistema di circolazione, i cuscinetti nella pompa possono venire protetti efficacemente dal venire danneggiati.A circulating pump protection device in a boiler comprises temperature and pressure sensors arranged in a suction pipe of a circulating pump, an analog-digital converter circuit connected to the sensors through insulated conductors, and a microcomputer having input end connected to the sensors and an output end electrically connected to the analog-digital converter circuit. The cavitation noise generated by the steam is partially produced by the water pressure lower than the vapor pressure of the water and when the circulation pump runs idle due to an insufficient flow of heating water in the circulation system, the bearings in the pump can be effectively protected from being damaged.
