AI Technical Summary
Condensate pumps operate in high-temperature environments, making them prone to corrosion and detachment. This leads to reduced efficiency, inability to drain water properly, equipment damage, and production downtime, affecting both production efficiency and product quality.
A flow meter is installed at the outlet of the condensate pump, connected in parallel with an electric angle valve. By detecting the condensate flow rate and the direct discharge pipeline, if the flow meter has no flow data, the electric angle valve is automatically activated to recover the condensate through direct discharge, thus avoiding the pump running dry for a long time.
It protected the condensate pump, prevented equipment damage, ensured normal production, and improved production efficiency and product quality.
