Stream and Vibration Condition can drive desiccant body to carry out disconnecting diving except wet construction, and driving main relay after alarming
The power supply of pump motor, to reach in the course of work and start-up course once electric leakage, circuit dampness and overheat occurs,
The technical purpose for notifying person on shore, automatic dehumidifying and disconnecting circuit in time, preventing fault harm further expansion.
For this purpose, technical solution provided by the utility model is, a kind of immersible pump monitoring and protective device, including successively connect
Sensor group, meter bus, arithmetic element and 485 bus interface connect, arithmetic element by data line respectively with police instruction
Lamp group, state instruction lamp group, desiccant body and main relay are connected, the output loop of main relay also with motor for submerged pump
It is connected, in which:
485 bus interface are by the measurement data from sensor group, and come from desiccant body, main relay and immersible pump
The status data of motor is interacted with external system；
The measurement data from sensor group is sent arithmetic element by meter bus；
Meter bus indicates signal collected with 4-20 milliamperes of electric currents.
Further, sensor group includes ponding sensor, temperature sensor, current transducer, humidity sensor and vibration
Dynamic sensor.
Further, police instruction lamp group includes ponding indicator light, overheating indicator lamp, overcurrent indicator light, high humility instruction
Lamp and strong amplitude indicator light.
Further, state instruction lamp group includes desiccant body status indicator lamp, main relay status indicator lamp and diving
Pump motor status indicator lamp.
The utility model has the following beneficial effects:
Firstly, the immersible pump monitoring of the utility model and protective device, include sensor group, can acquire in immersible pump in real time
Ponding, temperature and humidity, electric current and the Vibration Condition in portion, so that person on shore obtains the parameter information of immersible pump working condition in time,
And obtain alert notice；
Secondly, the utility model immersible pump monitoring and protective device, also with arithmetic element driving desiccant body with
The function of the actuating of relay carries out dehumidifying and disconnecting circuit after sensor group detects immersible pump status alert in time, from
And prevent fault harm further expansion.
It synthetically says, the immersible pump monitoring of the utility model and protective device can pass through sensor group and operation list
Member monitors the situation of motor in real time, increases substantially the service life of motor and the operation stability of motor, latent suitable for various specifications
Pump motor monitoring control, has apparent economic benefit.
