Dry burning, overload, phase loss and voltage instability are the most common causes of deep well pump failures and equipment burnout. To eliminate potential operational safety hazards fundamentally, Jinyu Pump has developed and upgraded a new generation of intelligent multi-protection technology equipped with a self-developed intelligent electronic control protection system. The system real-timely monitors core operating data including voltage, current, temperature and water level. It realizes millisecond-level automatic power-off and shutdown and synchronous fault warning records once abnormal conditions such as water shortage dry burning, abnormal voltage, load overload and line phase loss occur. Compared with the traditional single protection mode, Jinyu Pump’s intelligent protection technology achieves all-round, fully automatic and accurate safety control without real-time manual duty. It effectively avoids equipment damage caused by various working condition faults, greatly reduces operation and maintenance risks and maintenance costs, and comprehensively improves the operational safety and stability of deep well pumps.
