Description
Technical field
The water level and flow detection component used the present invention relates to a kind of control system of immersible pump.
Background technique
Immersible pump is the important equipment for transmit to Distance Transmission farther out or higher position the water source of water head site,
There is extremely wide application in numerous lives such as mining of groundwater, mine operation and fountain sight and production field, due to
Dive under water pump operation when, need to impregnate in water, therefore its drive motor is in fully sealed position, when causing its operation without
Method is radiated by air, and is fully relied on water flow and is radiated, if therefore when dive under water pump work when generation water shortage, in short-term
In will result in motor and burn, so that diving failure of pump is caused, simultaneously because immersible pump operating position is in water, so maintenance
Etc. being inconvenient, and in order to solve this problem, current common method is that increase water level switch on immersible pump latent to control
Shut down in time when water pump water shortage, but discovery in use, it is single on the one hand cannot be fully effective to latent by water level switch
Water pump carries out water shortage protection, while can not also be monitored to the working condition of diving pump operation, and in pump operation of diving under water, in addition to
Phenomena such as water level decline is outer, motor fault, the blocking of immersible pump water inlet will also result in immersible pump generation motor and burn
Failure, it is therefore desirable to a kind of new immersible pump water shortage management method and equipment are developed, to improve immersible pump operational management ability,
And necessary anticipation can be made to diving failure of pump.
In the prior art, Chinese patent (CN104712561B, a kind of immersible pump water shortage automatic protecting control device and use
Method) in order to solve problem above, following technical scheme is proposed, the control method of immersible pump water shortage automatic protection is by water
The detection of source liquid level, the detection of immersible pump water inlet water flow and immersible pump driving motor running temperature detection three classes diving
Pump operation parameter detecting, and data will test by carrier communication and transmitted at a distance, at the same to immersible pump exsiccosis into
The timely shutdown processing of row, immersible pump water shortage automatic protecting control device, including controller, water level controller, drainage tube, temperature pass
Sensor and flow sensor.
It detects water source liquid level sensed water level height when independent by the detection of setting water level, flow and temperature
When less than immersible pump minimum operation water level, then illustrate that immersible pump is up into water shortage operating status.
When individually detecting that immersible pump water inlet water flow works normally water suction range of flow lower than immersible pump, then
Illustrate that the blocking water inlet of immersible pump water inlet is unsmooth.
Detect immersible pump driving motor running temperature and driving motor maximum running temperature gap less than 3-10 when independent
DEG C when, then illustrate magnet exciting coil failure inside immersible pump driving motor.
Water suction range of flow and latent is worked normally lower than immersible pump when being detected simultaneously by immersible pump water inlet water flow
When water pump driving motor running temperature and driving motor maximum running temperature gap are less than 3-10 DEG C of two groups of data, then explanation is latent
Pump motor generation operating load is excessive, and submersible pump rotor rotational resistance is excessive.
This covering device is very cumbersome, and real cost of production increases, sensor element, high failure rate, and stability is low.Especially
Water level detecting uses floating ball and connecting rod, and device occupied space is big.In addition, floating ball and connecting rod are located at outside immersible pump, make in river
Used time is easy the interference by screw clamp or other sundries, it is inaccurate to lead to water level detecting, and then lead to pump working state
