The utility model has the advantages that the starting or the stopping of the water pump is automatically controlled according to the liquid level sensor, the water pump can be started to run in an alternate circulating manner according to the height of the liquid level, and the utility model can control a plurality of water pumps for work at the same time, and also can control at least one water pump for work; and in addition, a series of protection of short circuit, overcurrent, low-current, phase failure and water leakage is adopted for the water pump, so that the normal work of the water pump is ensured.
Description
Technical field
The utility model relates to pumping plant, relates in particular to a kind of pumping plant blowdown liquid level automatic control device.
Background technique
The blowdown pumping plant is widely used in occasions such as building site, hospital, municipal administration, traffic, residential quarters, hotel and carries out blowdown, sewage treatment etc.At present, the proof submersible sand discharging pump that draining is used has a dual mode in control: a kind of is to adopt manual monitoring, opens and stop the running of submersible pump according to the height of water level by the special messenger, and deficiency is to need the special messenger to nurse, and automaticity is not high, uses inconvenience; Another kind is the start and stop of adopting external electric control box control pump, and electric control element adopts electromagnetism contact control element more in this mode, complex structure, and the life-span is short, poor reliability, rate of fault height; And electric control box separates with the pump housing, and installation, transportation and use are all inconvenient, need take certain space during installation.
The model utility content
The technical problems to be solved in the utility model is: a kind of convenient, pumping plant blowdown liquid level automatic control device that automaticity is high is provided.
In order to overcome the defective that exists in the background technique; the technological scheme that its technical problem that solves the utility model adopts is: a kind of pumping plant blowdown liquid level automatic control device; comprise programmable controller; the water pump and the text display operator of band protector; described water pump; text display operator and programmable controller electrically connect; described pumping plant is provided with liquid level sensor; described liquid level sensor and programmable controller electrically connect; be provided with detector and circuit breaker in the described protector, described detector; circuit breaker and programmable controller electrically connect.
According to another embodiment of the present utility model, pumping plant blowdown liquid level automatic control device comprises that further described water pump, text display operator are connected with programmable controller by the MODBUS-RUT agreement.
According to another embodiment of the present utility model, pumping plant blowdown liquid level automatic control device comprises that further described water pump starts by the mode of self coupling step-down.
The utility model has solved the defective that exists in the background technique, the beneficial effects of the utility model are, start or stop according to the liquid level sensor automatically controlled water pump, and can take turns loop start operation water pump at height according to liquid level, the utility model can be controlled many pump workings simultaneously, also at least one pump working of may command.In addition water pump is adopted short circuit, excess current, low current, phase shortage, a series of protections of leaking, guaranteed the proper functioning of water pump.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of pumping plant blowdown liquid level automatic control device as shown in Figure 1; the water pump and the text display operator that comprise programmable controller, band protector; described water pump, text display operator and programmable controller electrically connect; described pumping plant is provided with liquid level sensor; described liquid level sensor and programmable controller electrically connect; be provided with detector and circuit breaker in the described protector, described detector, circuit breaker and programmable controller electrically connect.By liquid level sensor the pumping plant liquid level signal is transmitted programmable controller,, the data after handling are shown the pumping plant liquid level by the text display operator by the data processing of programmable controller.And relevant parameters such as water pump electric current are to detect the pump operation situation constantly by the detector that is arranged in the water pump, to detect data and be sent to programmable controller, by the data processing of programmable controller, the data after handling are shown the relevant parameters such as electric current of water pump by the text display operator.
Be short-circuited when detector detects water pump, excess current, low current, phase shortage, when situation such as leaking; to detect data and be sent to programmable controller, by the data processing of programmable controller, and then the control circuit breaker; water pump and circuit are disconnected, thereby play the effect of protection water pump.
Described water pump, text display operator are connected with programmable controller by the MODBUS-RUT agreement, thereby can read the relevant parameters such as electric current, voltage of water pump at the text display operator, understand the pump operation situation constantly.In addition, the text display operator is write-in program simply, control pumping plant liquid level, and according to the operation of pumping plant water level height control of pump loop start.
Described water pump starts by the mode of self coupling step-down, by at component such as the inner increase of water pump transformers, makes the starting resistor of pump motor reduce, thus the working life that can improve water pump greatly.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
