Description
Technical field
The utility model relates to a kind of submersible pump automatic control technology.
Background technique
The design deficiency of the basement in a lot of electric substations hyperbaric chamber owing to building throughout the year seep water (can't make up), annual flood season particularly, the very large normal operation to high pressure 6kv equipment of water percolating capacity causes very large potential safety hazard, establish submersible pump for this reason in a wet pit is built in the rises, adopt magnetic starter to control manually the submersible pump start-stop on ground.There is certain defect in the submersible pump control gear that starts and stop by manual control submersible pump, be difficult to control water discharge time (there is uncertain factor in water percolating capacity) and will establish special messenger's nurse when water percolating capacity is large, submersible pump (during the submersible pump running, motor is by water cooling) human accident is burnt in careless slightly will precocity the water full excessive or anhydrous running of submersible pump, therefore, be necessary to develop a kind of submersible pump unit that can automatically control start and stop.
The model utility content
The purpose of this utility model is the difficult problem of controlling of time that starts and stop in order to solve manual control and submersible pump, and a kind of submersible pump automatic controller is provided.
submersible pump automatic controller described in the utility model comprises submersible pump, the spacing meter of water level, A.C. contactor, fus, the time relay and thermorelay, the control coil KT of the described time relay connects with the limit switch LSK of the spacing meter of water level and consists of the first series arm, the coil KM of A.C. contactor connects with the time-delay normally opened contact KT1 of the time relay and consists of the second series arm, described the second series arm and the first series arm formation in parallel parallel branch, the normally-closed contact RJ1 of described parallel branch and thermorelay, fus is connected between any live wire and zero line of power supply circuits of three-phase alternating-current motor M of submersible pump, the main contact KM1 of A.C. contactor and the coil RJ of thermorelay are connected in the current supply circuit of three-phase alternating-current motor of submersible pump.
Submersible pump automatic controller described in the utility model also comprises air-break switch ZK, and described air-break switch ZK is connected in the current supply circuit of three-phase alternating-current motor M of submersible pump.
Submersible pump automatic controller described in the utility model is controlled the submersible pump startup by the limit switch LSK of the spacing meter of water level, controlling submersible pump by the clocking capability of the time relay stops automatically, need not manually to control submersible pump starts and stops, eliminate the accident that the submersible pump unit of manual control may cause, also avoided unnecessary personnel's waste simultaneously.
Description of drawings
Fig. 1 is the structural representation of submersible pump automatic controller described in the utility model;
Embodiment
embodiment one: present embodiment is described in conjunction with Fig. 1, the described submersible pump automatic controller of present embodiment comprises submersible pump, the spacing meter of water level, A.C. contactor, fus, the time relay and thermorelay, the control coil KT of the described time relay connects with the limit switch LSK of the spacing meter of water level and consists of the first series arm, the coil KM of A.C. contactor connects with the time-delay normally opened contact KT1 of the time relay and consists of the second series arm, described the second series arm and the first series arm formation in parallel parallel branch, the normally-closed contact RJ1 of described parallel branch and thermorelay, fus is connected between any live wire and zero line of power supply circuits of three-phase alternating-current motor M of submersible pump, the main contact KM1 of A.C. contactor and the coil RJ of thermorelay are connected in the current supply circuit of three-phase alternating-current motor of submersible pump.
The described submersible pump automatic controller of present embodiment in actual use, the spacing meter of water level is positioned over wet pit inside, determine as required the height of the spacing meter of water level, according to the timing time of the water yield that will discharge and submersible pump watt level set time relay.
Embodiment two: present embodiment is described in conjunction with Fig. 1, the difference of present embodiment and the described submersible pump automatic controller of mode of execution one is: described device also comprises air-break switch ZK, and described air-break switch ZK is connected in the current supply circuit of three-phase alternating-current motor M of submersible pump.
Working principle
Submersible pump automatic controller described in the utility model utilizes water level in the spacing meter monitoring of water level wet pit, when water level meets or exceeds the spacing meter of water level position, the limit switch LSK of the spacing meter of water level is closed, electric, its time-delay normally opened contact KT1 closure that the coil KT of the time relay gets, electric, its main contact KM1 closure that the coil KM of A.C. contactor gets, the current supply circuit conducting of submersible pump, submersible pump is started working; When water level drops under the spacing meter of water level position, the limit switch LSK of the spacing meter of water level disconnects, the coil KT dead electricity of the time relay, the time relay begin timing, when time relay timing finishes, its time-delay normally opened contact KT1 disconnects, the coil KM dead electricity of A.C. contactor, its main contact KM1 disconnect, and the current supply circuit of submersible pump disconnects, and submersible pump cuts off the power supply and quits work.
Submersible pump automatic controller described in the utility model is controlled the submersible pump startup by the limit switch LSK of the spacing meter of water level, utilize the clocking capability control submersible pump of the time relay automatically to stop, need not manually to control submersible pump starts and stops, eliminate the accident that the submersible pump unit of manual control may cause, also avoided unnecessary personnel's waste simultaneously.
