FCI provides move switch to protect from dry running

เกจ์ออกซิเจนsumo swap provides an early warning alert to the potential of dry operating situations, cavitation and other pump issues that can result in emergency shutdowns and costly maintenance.

FCI’s FLT93 Series circulate swap reliably displays the circulate and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, the place sudden, unexpected reductions in media move rates can leave pumps susceptible to over-heating situations that shutdown course of strains and require troubleshooting and fixing. The SIL2 rated instrument is intended for heavy-duty, doubtlessly hazardous process trade environments and comes with a comprehensive listing of world safety approvals.
It has a no moving components design and presents a robust scheme for pump safety with its dual alarm capability. With Alarm 1, the switch detects a low flow scenario anyplace between 0.01 and 3 ft per second FPS (0.003–0.9 m per second MPS). This low circulate alarm is a pre-warning sign for the control system or operator who can then resolve to keep the pump operating or to close it down.
If an Alarm 2 occurs as a result of the feed line to the pump is running dry, this may be an emergency signal to close down the pump immediately as a outcome of the bearings now see gas instead of a liquid as a heat switch media. In such situations, the temperature of the bearings might rise very fast. Using a flow change prevents permanent damage to the pump’s bearings.
