1. Install protection devices

Equip with low-flow sensors, suction pressure switches, dry-run relays for auto-shutdown on anomalies.

2. Optimize operation procedures

Ensure full priming before startup; ban long idle running; assign regular parameter checks.

3. Upgrade pipeline design

Add recirculation line for minimum lubrication flow; install inlet check valve to prevent backflow.

4. Strengthen maintenance

Calibrate sensors/alarm systems regularly; inspect inlet filters frequently to avoid blockage.
