Problems solved by technology
[0002] In industrial production, there will be many water storage equipment, and the water in the water storage equipment will be gradually consumed. At this time, it is necessary to replenish water to the water storage equipment, and this work requires special personnel to monitor and add water at any time, which is very It is a waste of manpower, and human monitoring will inevitably make mistakes, resulting in untimely water addition. Most of the existing control devices for automatic control of water pumps use intelligent controllers such as single-chip microcomputers, but in harsh environments, intelligent controllers will frequently be damaged.

The invention, which belongs to the water level control device field, relates to a self-control pump water-level control device comprising a water level sensor including a high water level sensor and a low water level sensor. The high water level sensor and the low water level sensor are connected to a signal receiving terminal of the control device; and a signal output terminal of the control device is connected with a water pump. The control device controls the water level according to signals fed back by the high water level sensor and the low water level sensor. Therefore, the water level can be controlled effectively; the manual intervention can be avoided; the manpower can be saved; the operation is stable; and the control device can adapt to a severe environment.
Description
technical field [0001] The invention relates to a water level control device for an automatic control pump, which belongs to the field of water level control devices. Background technique [0002] In industrial production, there will be many water storage equipment, and the water in the water storage equipment will be gradually consumed. At this time, it is necessary to replenish water to the water storage equipment, and this work requires special personnel to monitor and add water at any time, which is very It is a waste of manpower, and human monitoring will inevitably make mistakes, resulting in untimely water addition. Most of the existing control devices for automatic control of water pumps use intelligent controllers such as single-chip microcomputers, but in harsh environments, intelligent controllers will frequently be damaged. . Contents of the invention [0003] The invention provides an automatic control pump water level control device, which can effectively co...
