Embodiment 3
The utility model also provides a kind of water pump controller of the following course of work:
When after starting mode of pump, namely the motor of water pump starts working, now, if there is normal discharge to pass through in water pipe, then water jet propulsion current lodicule 6 makes the closing of contact of described microswitch 2, if discharge is less in feed pipe, or when not having discharge, then the contact of described fine motion exploitation can not close, and is namely in off-state; In Preset Time, as in 10S, whether the contact detecting described microswitch 2 closes, when the closing of contact of described microswitch 2, water pump normally works, when in Preset Time, as the contact of microswitch 2 as described in detecting in 10S there is no a normally closed time, then after Preset Time, namely after 10S, switch off the pump.
After water pump is opened, the described microswitch 2 of discharge switch does not have closed reason to have: the first, and water supply network has been cut off the water, and causing does not have water in water pipe; The second, water pump plugs, and causes water pump can not by the water in water supply network in normal suction water pipe; 3rd; short circuit in water pump; cause water pump can not by the water in water supply network in normal suction water pipe; during arbitrary middle generation in these three kinds of situations or more susceptible condition; the automatic pump controller that the present embodiment provides can stop water pump in Preset Time (10S), then protect water pump.
When the automatic pump controller that the present embodiment provides, for control water tower supply water water pump time, following situation will be had to occur: when water tower level is for time full, the float valve of column head will be closed, then will not have current in water pipe, under normal circumstances, fork 4 in described discharge switch can under the pulling force effect of extension spring 7, and get back to original position, microswitch 2 disconnects, this just can switch off the pump for time full at water tower level in time, avoids the waste of water resource; If fork 4 or extension spring 7 are due to malfunctioning and when can not get back to original position, then microswitch 2 can not disconnect, now water pump also can continue to supply water, in such cases, over-current detection circuit can detect that the electric current flowing through pump motor is greater than preset value, then also can close water cut-off pump, this just further ensures the safety in water pump use procedure.
The timing circuit that this enforcement provides can arrange the automatic start-up time of water pump, and described automatic start-up time can be divided into two kinds: the first, Preset Time point starts, and as in one day 24 hours, exports at interval of 1 hour 30 minutes the signal starting water pump; The second, interval Preset Time starts, as hour outputs such as automatic spacing 1,3,6,12,24 start the signal of water pump automatically.By arranging timing circuit, easy to use, as concentrating in the community needing water pump to fetch water to water tower, by the start-up time of each water pump that staggers, avoiding discharge and can not meet the problem that each water pump starts simultaneously.And the automatic pump controller that the present embodiment provides adopts mechanical rotational potentiometer to realize starting Preset Time point can be in harmonious proportion that to start interval Preset Time adjustable, intuitively and easily operate.Timing circuit in the present embodiment can adopt 51 single-chip microcomputers and chip DS1302 to realize, and as shown in Figure 4, because timing circuit is more common in the prior art, can think known technology, so be not described in detail in the present embodiment.
Simultaneously, the automatic pump controller that the present embodiment provides, when timing circuit does not export the signal starting water pump, can emergency starting water pump, manual position is pushed by automatic/hand switch, common by automatic/hand switch is connected with the first contact, then can feed pump control relay coil electricity, emergency starting water pump; When the water level of water tower is for time full, then still can close water cut-off pump by the microswitch 2 in discharge switch.After having a power failure suddenly, then when being energized, the automatic pump controller that the present embodiment provides can restart.
In automatic pump controller as shown in Figure 3, when the first contact of automatic/hand K switch-3 is connected with common, and when the microswitch of described discharge switch closes, the coil electricity of water pump control relay, water pump can work; When the second contact of automatic/hand K switch-3 is connected with common, and triode Q1 conducting, when the microswitch of discharge switch closes, the coil electricity of water pump control relay, water pump can work.
The automatic pump controller that the present embodiment provides, required dc source can be obtained by rectification circuit and filter circuit, the input of described rectification circuit is connected with external power supply, the output of described rectification circuit is connected with filter circuit, and the output of described filter circuit is as the output of described dc source.Rectification circuit in Fig. 3 adopts full-bridge rectification bridge to realize, and those skilled in the art should be appreciated that and adopt other rectifier system to be also fine, as long as the direct current realizing external AC to be converted into predeterminated voltage is just passable.Filter circuit in Fig. 3 adopts RC filtering to realize, and the dc source exported can be made to stablize more gently by arranging filter circuit.As shown in Figure 3, described DC power supply circuit can also comprise Zener diode D68, and the negative electrode of described Zener diode D68 is connected with the output of described filter circuit, the plus earth of described Zener diode D68.By arranging Zener diode D68, then, when the voltage that filter circuit exports is excessive, puncturing Zener diode D68, making large voltage discharge the safety that ensure that subsequent conditioning circuit.
The automatic pump controller that the present embodiment provides, red light emitting diodes can also be connected in external power supply loop, then, when external power supply normal power supply, the red led on automatic pump control panel is bright; Green emitting diode can also be parallel to the two ends of the contactor coil of water pump control relay, then when contactor coil energising, contactor closes, and during water pump normal water supply, the green indicating lamp on automatic pump control panel is bright.
The present embodiment provides automatic pump controller, as shown in Figure 5, panel only has interval hour rotational potentiometer, start-up time rotational potentiometer, start/stop button, an emergency starting button and a power supply indicator and run indicator, operate very simple, intuitive, just can use without the need to manual.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
