Description
Technical field
The utility model relates to water level monitoring device fields, are based on air pressure and water more particularly to one kind in the field
The Novel sewage elevator pump water level monitoring system of position electrode.
Background technique
The water level monitoring of existing sewage pump only relies only on level electrode, is more than that high water level electrode starts water pump, is lower than
Low water level electrode stops water pump.When there are dirt and damage in level electrode surface, whole system will be because not acquiring start and stop
Signal leads to cisco unity malfunction;The setting of level electrode is generally two to three gears, cannot accomplish the monitoring of continuous liquid level,
When the impeller of water pump, which goes wrong, is unable to normal pumping, water pump can only be monitored by the pump working time whether extremely, when
When sewage caching tankage is excessive, the working time of water pump is longer, causes the serious waste of the energy.Furthermore level electrode is commonly used
Detection is most of to select direct current scheme, level electrode electrification, chassics earth, the explanation when detecting that the electrode voltage is low level
Liquid level reaches the level electrode, since the conductivity of sewage is higher, after electrification level electrode is grounded by sewage, is easy to make electrode
It is electrolysed, long-play will lead to the damage of electrode.There are also the 4-20ma liquid levels that part of contaminated water pump product selects customization
Meter, price is more expensive, and volume production is costly.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of Novel sewage based on air pressure and level electrode
Elevator pump water level monitoring system.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
A kind of Novel sewage elevator pump water level monitoring system based on air pressure and level electrode, thes improvement is that: institute
The system stated includes shell, the baroceptor and electrode cable installing controller in shell and being electrically connected with the controller,
Wherein baroceptor is connected with the snorkel stretched out outside shell, and the end of snorkel is connected with air guide amplifier tube, air guide
The bottom end of amplifier tube is inserted to liquid level or less;Electrode cable stretches out outside shell, and end is connected with the level electrode of neighbouring liquid level,
There are four the level electrodes, is followed successively by public electrode, low electrode, middle electrode and high electrode from low to high, wherein common electrical
Pole is powered using exchange.
Further, the controller is single-chip microcontroller.
Further, signal condition and filter amplification circuit are additionally provided between controller and baroceptor.
Further, AC signal is delivered to public electrode through signal conditioning circuit.
Further, low electrode, middle electrode and high electrode pass through signal processing and AC/DC conversion circuit and controller electricity
Connection.
The beneficial effects of the utility model are:
Novel sewage elevator pump water level monitoring system disclosed in the utility model based on air pressure and level electrode, by air pressure
Sensor dominates the continuous monitoring of sewage level, level electrode auxiliary, when baroceptor and level electrode any one go out
When existing problem, the normal operation of system is not influenced, improves the accuracy and stability of system.When pump working, pass through liquid level
And the change rate of time, it can quickly judge the abnormal conditions of pump working, safety that is energy saving and improving system.Furthermore
System also has low-cost advantage compared with liquidometer.
