High-efficiency energy-saving multi-stage pumps are widely used in modern industrial fields. Their stable performance, large flow rate, and high head make them perform excellently in various production environments. To ensure the safe operation of multi-stage pumps and improve their efficiency, the configuration of monitoring and protection accessories is particularly important. The following will detail the functions and principles of these accessories.

I. Functions and Principles of Monitoring Accessories

1. Flow Monitor: Used to monitor the flow rate of the multi-stage pump in real-time, ensuring its operation within the specified range. When the flow rate is below or exceeds the set value, it will issue an alarm and automatically adjust or shut down to avoid equipment damage and energy waste. Its working principle is mainly to indirectly calculate the flow rate by measuring the fluid pressure or velocity.

2. Temperature Sensor: Used to monitor the operating temperature of the multi-stage pump. When the temperature is too high, the sensor will issue an alarm and activate the cooling system or adjust the pump's operating status to prevent damage from overheating. Its principle is to detect the temperature using a thermistor or thermocouple.

II. Functions and Principles of Protection Accessories

1. Overload Protector: Used to prevent equipment damage caused by motor overload. When the motor current exceeds the set value, the overload protector will automatically cut off the power to protect the motor from damage. Its principle is to determine whether the motor is overloaded by detecting the current and voltage.

2. Leakage Detector: Used to detect the sealing performance of the multi-stage pump and prevent liquid leakage from polluting the environment. When a leak is detected, it will issue an alarm and automatically shut down. Its principle is to determine whether a leak has occurred by detecting changes in liquid pressure or mass.

3. Vibration Monitor: Used to monitor the vibration status of the multi-stage pump and prevent equipment damage caused by abnormal vibration. When the vibration exceeds the set value, the monitor will issue an alarm and prompt for shutdown and inspection. Its principle is to detect the pump's vibration status using a vibration sensor.

In summary, the monitoring and protection accessories of high-efficiency energy-saving multi-stage pumps play an important role in ensuring the safe operation of the equipment and improving its efficiency. These accessories, through different working principles, achieve real-time monitoring and protection of key parameters such as flow rate, temperature, overload, leakage, and vibration of the multi-stage pump, ensuring that the multi-stage pump can operate stably in various production environments and provide reliable assurance for enterprise production.
