Embodiment
The present inventor develops a kind of control of dredge pump automatic detecting device first by in-depth study extensively
Circuit.The purpose of this utility model is to carry out automatic detecting to water pump in the case of untapped for a long time for dredge pump, when
Water level can interrupt inspection immediately when rising, and pump direct plunges into operation.
The utility model circuit is using the time relay KT1, KT2, auxiliary reclay KA7, indicator lamp HL6, composition control
Circuit.Automatic position is got to by switch, a time relay KT1 is met, sets setting valve (i.e. timing) as 240 hours,
When under the situation that timing to dredge pump also off-duty is crossed, KT1 turns on adhesive auxiliary reclay KA7 and KT2, transports two pumps
Row gets up, and inspection indicator lamp is HL6.KT2 setting values are 5 seconds, and KA7 is interrupted after waiting pump operation 5 seconds, and pump is out of service, so as to real
Existing automatic inspection function, prevents water pump from not having to and getting rusty for a long time.
The utility model is completed on this basis.
The setting valve of first relay can be set to 120 hours, 168 hours, 240 hours, 360 hours, 480 hours or
Person 720 hours.
The run time of second relay may be set to 3 seconds, 5 seconds, 10 seconds, 20 seconds, 30 seconds or 60 seconds.
Major advantage of the present utility model includes：
(a) control circuit of the present utility model can be with the time of field requirement regulating time relay, so as to change pump
Run time and monitoring time, be suitable for the needs of various control pattern；
(b) control circuit of the present utility model, its circuit structure is simple, easy to operate, and cost is cheap.
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.
It should be noted that in the claim and specification of this patent, such as first and second or the like relation
Term is used merely to make a distinction an entity or operation with another entity or operation, and not necessarily requires or imply
Any this actual relation or order be present between these entities or operation.Moreover, term " comprising ", "comprising" or its
