Description
Technical field
The invention belongs to water pump control technology field, it is related to a kind of Based Intelligent Control structure of water pump, particularly a kind of automatic
Control the Based Intelligent Control structure of pump motor start and stop.
Background technology
There is drawback in traditional water pump：During pump water, only operated by rule of thumb, to the water level at A toward at B at A using water pump
Cannot monitor, easily cause sky and take out.Some water pumps are configured with mechanical switch or electrical switch carrys out automatically controlled water pump start and stop at present.
For example, Chinese patent discloses a kind of automatic pumping water pump [Authorization Notice No. be CN202266399U], including the pump housing, motor and
Pressurized tank, the side of the pump housing is provided with gland, and the pump housing is provided with water inlet and outlet, and the pump housing is connected with motor, pressurized tank with
The pump housing is connected, and water pump also includes pressure switch, and pressure switch is located at the one side lower end of the pump housing, the electricity of pressure switch and water pump
Source electrically connects.When hydraulic pressure at water falls below the minimal pressure force value of pressure switch design, pressure switch automatically opens up, and
Start pump power, water pump is carried out drawing water work；When hydraulic pressure at water rises to the maximal pressure force value of pressure switch design,
Pressure switch is automatically switched off, and simultaneously closes off pump power, and water pump quits work.
But above-mentioned water pump still suffers from problems with：Structure arrangement is unreasonable, and structure is not compact, installs required spatial loop
Border is larger, is unsuitable for some narrow spaces, and the scope of application is little；Need to put into substantial amounts of fund and water pump, pressurized tank etc. are carried out
Individually buy, and also need to take a significant amount of time water pump to be installed, higher to the skill set requirements of workman；Pressurized tank, pressure leave
Pass significantly impacts the service life of water pump outside being chronically exposed to when using in the presence of a harsh environment；This water pump globality is poor,
Carrying or transport are inconvenient.
And for example some water pumps are by increasing wiring board come receipt signal thus reaching the purpose controlling water pump start and stop, but existing
The water lev el control of water pump and protection be required to an external control case, electric pump power line is connected to control chamber, and by water level switch,
Temperature detect switch (TDS) equisignal line is also connected to control chamber, by the signal of wiring board receives input in control chamber and detect electric current electricity
Pressure value is controlling the start and stop of electric pump.Because control chamber is the outside being external in submersible pump, during use, there is problems with：For
Mobile frequently or electric pump work under bad environment, particularly for the place in field such as construction, using not convenient, during use for
The waterproof of control chamber and install all extremely inconvenient, and because holding wire is more, also extremely inconvenient for adjunction electric wire, using without
Ji.
