What are the reasons for the pump to stop automatically? What should be done in this situation? http://bbs.hcbbs.com/static/image/hrline/4.gifhttp://bbs.hcbbs.com/static/image/hrline/4.gif Answer: Reason: (1) Excessive operating time ； (2) Excessive overload time ； (3) The motor or pump fails. Treatment: (1) Switch to the backup pump ； (2) Check the pump that stopped automatically to identify the cause ； (3) After the fault is resolved, conduct a trial run; if it cannot be eliminated, hand it over to the equipment maintenance fitter for handling.
Power outage; the motor burned out. Handle it as a power outage; start the standby pump
Motor-related issues, bearing box problems, issues with the pump itself: External factors: power outages, misoperations. Start the backup pump to maintain production first, and then investigate the cause of the pump shutdown

Power outages, mechanical failures, system interlocks. Handle it by shutting down power, activating a backup pump, troubleshooting to unlock it, or manually.
Answer: Reasons: (1) Excessive operating time; (2) Prolonged overload; (3) Fault in the motor or pump. Handling: (1) Switch to the backup pump; (2) Check the pump that stopped automatically to identify the cause; (3) Eliminate the fault
Answer: Reason: (1) Excessive operating time； (2) Excessive overload time ； (3) The motor or pump fails. Treatment: (1) Switch to the backup pump ； (2) Check the pump that stopped automatically to identify the cause ； (3) After the fault is resolved, conduct a trial run; if it cannot be eliminated, hand it over to the equipment maintenance fitter for handling.
(1) Excessive operating time； (2) Excessive overload time ； (3) The motor or pump fails. (4) Power supply issue (5) The protection current is set too low
Reason: 1. Motor issues, such as motor overcurrent protection. 2. Mechanical interlocks, such as vibration and temperature. 3. Process interlocks, such as low liquid level in the suction tank. Solution: 1. Contact the electrical repair team. 2. Contact the maintenance team. 3. Contact the instrument repair technician.
Reasons: 1. Interlock; 2. Overcurrent; 3. Power outage. Solutions: 1. Reset the interlock; 2. Restore power supply and restart, being careful of the current level; 3. Apply protection measures such as current protection and voltage protection based on the actual situation, as well as address cases of widespread power outages
