Abstract
The utility model relates to the technical field of liquid transfer, in particular to a novel automatic no-load protection type water pump, which is applicable to a high lift. The novel water pump of the automatic no-load protection type comprises a water pump body, a check valve, a pressure sensor and a circuit board, wherein the check valve is installed at a water outlet of the water pump body and preventing a medium from flowing back; the pressure sensor is installed inside the water pump body and contacts the medium at the water outlet; and the circuit board is installed inside the water pump body and controls a motor in the water pump body to work according to a signal provided by the pressure sensor. The novel water pump of the automatic no-load protection type has the advantages as follows: the check valve and the pressure sensor are installed at the water outlet of the water pump body, the pressure sensor detects the flow rate and the pressure at the water outlet and supplies the signal to the circuit board, and the circuit board controls the motor in the water pump body to work, so that the water pump can be prevented from working at a low efficiency point for a long time and the service life of the water pump is prolonged.
Description
Technical field
The utility model belongs to liquid conveying technology field, refers in particular to a kind of high-lift novel unloaded automatic protection type water pump that is applicable to.
Background technique
At present, the function that the submersible pump on the market does not have automatically controlled water pump to open and close mostly owing to being in different operating points during water pump operation, causes the working efficiency of water pump inconsistent, when water pump for a long time when low efficiency point is moved, can greatly reduce its working life.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, safe and reliable novel unloaded automatic protection type water pump.
The purpose of this utility model is achieved in that
A kind of novel unloaded automatic protection type water pump comprises water pump body;
Safety check, it is installed in the water outlet of water pump body and stops medium to flow backwards;
Pressure inductor, its be installed in water pump body inside and with the medium contact of water outlet; And
Circuit board, its be installed in the water pump body and the SC sigmal control water pump body that provides according to pressure inductor in the action of motor.
Above-mentioned safety check is Lift check valve, and Lift check valve comprises the valve seat that is installed on the water pump body water outlet inwall, and the valve seat middle part is connected with connecting rod, and the lower end of connecting rod is equipped with spool, is set with Returnning spring on the connecting rod between spool and the valve seat.
The utility model compared to existing technology outstanding and useful technique effect is:
The water outlet of water pump body of the present utility model is equipped with safety check and the pressure inductor that stops medium to flow backwards; pressure inductor detects flow and the pressure of water outlet; the signal that provides is to circuit board; the action of the motor in the circuit board control water pump body; when the pressure at pump outlet place greater than 1.3bar (± 0.2) or flow during less than 90ml/min; circuit board all will be controlled pump motor and quit work; also be provided with the no-load protection function in the circuit board; can effectively avoid water pump for a long time in the low efficiency point operation, prolong the working life of water pump.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of safety check of the present utility model.
Fig. 3 is the schematic diagram of pressure inductor of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3;
A kind of novel unloaded automatic protection type water pump comprises water pump body 1;
Above-mentioned safety check 4 is Lift check valve, Lift check valve comprises the valve seat 41 that is installed on water pump body water outlet 2 place's inwalls, valve seat 41 middle parts are connected with connecting rod 43, and the lower end of connecting rod 43 is equipped with spool 44, are set with Returnning spring 42 on the connecting rod 43 between spool 44 and the valve seat 41.
The utlity model has no-load protection, automatic flow sensing and pressure sensitive function.Behind the water pump plugged, enter automatic control state, pressure inductor can detect flow and the pressure at pump outlet place, when the pressure at pump outlet place greater than 1.3bar (± 0.2) or flow during less than 90ml/min, circuit board all will be controlled pump motor and quit work.When circuit board detects the signal obtain and judges that water pump is in no-load running according to pressure inductor (do not have in the water pump water then water pump be in unloaded state), this moment, circuit board entered the cycle detection state, the water pump 30S that turns round first stops 5S again, four cycles and so forth, detect the signal that obtains such as pressure inductor and judge that still water pump is in no-load running, then pump motor quits work, and then per 24 hours repeat above-mentioned detection once.
Flow sensing and pressure sensitive function are automatically: by the pressure condition in the pressure inductor induction water pump, when the force value in the water pump surpassed 1.3bar, water pump can stop behind operation 10s automatically.When the pump internal pressure returned to 1.3bar, water pump can restart.Thereby circulation reaches the function of automatic control control water pump and protection water pump and so forth.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
