Positive displacement pump output monitor |
摘要 |
Disclosed is a positive displacement pump output monitor which is employed by (a) passing the discharged fluid from said pump through a pulse receiving chamber, the pressure of said pumped fluid during the discharge stroke of the pump causing a diaphragm in said pulse receiving chamber to be moved outwardly by said fluid; (b) causing the outward concurrent movement of a spring-loaded metal shaft when the diaphragm is moved outwardly; (c) contacting a fixed element with said outwardly moved spring-loaded shaft, thereby causing a time-delayed relay connected to said fixed element to be reset; and (d) causing said time-delayed relay to send an alarm signal to an alarm annunciation means if said relay is not reset within a predetermined amount of time.
