Abstract
The utility model relates to an automatic circulating cooling water feeding device which comprises a floater arranged in a water tank, wherein the floater comprises a hollow floater, a pair of contacts arranged at the bottom of the hollow floater and a conductive sphere which is arranged on the pair of contacts, wherein the contacts are connected with a power switch control circuit arranged on a water feeding pump, and a lead wire connected with the contacts in the water tank is provided with a fixed node or is connected with a balancer. When the automatic circulating cooling water feeding device works, the floater is floated on the surface of water in the water tank, and the conductive sphere is arranged on the pair of electrode contacts; and when the water level drops, the position of the node is basically fixed, therefore, the floater gradually inclines until the conductive sphere is separated from the pair of electrode contacts so that the power switch control circuit of the pump is used for measuring that the water level is lower than a set value, the water pump is controlled to feed water until the floater ascends to a set height, and when the conductive sphere comes back to the pair of electrode contacts, the automatic circulating cooling water feeding device is used for controlling the water feeding pump to stop working.
Description
Technical field
The utility model relates to a kind of recirculated cooling water automatic water-supply apparatus.
Background technology
Existing recirculated cooling water automatic water-supply apparatus often adopts the level sensor that is arranged on differing heights to judge the water level in the water tank.In case during level sensor incrustation, the function of its water level detecting has just been lost, cause going up by mistake and when water or water tank do not dry up water.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, reliability recirculated cooling water automatic water-supply apparatus preferably.
In order to solve the problems of the technologies described above; The utility model provides a kind of recirculated cooling water automatic water-supply apparatus; It comprises: be located at the float in the water tank, this float comprises: hollow buoyancy aid, be located at the pair of electrodes contact of this hollow buoyancy aid bottom and alternate setting and be positioned over this to the conductor ball on the electrode contact; Described pair of electrodes contact links to each other with the water level signal input of the power on-off control circuit of charging pump; With lead that described pair of electrodes contact links to each other on exist a node to be fixed in the water tank, or be connected with a counterweight and place water tank; The conductor length between this node and the said float and the water level higher limit of water tank are corresponding.
As the embodiment of optimizing, the spherical in shape or olive shape of said hollow buoyancy aid.
Make said conductor ball from space that described pair of electrodes contact tumbles when further, having the contiguous said node of the water level that is suitable in water tank in the said hollow buoyancy aid.
As the embodiment of optimizing, the inner wall smooth of said hollow buoyancy aid.
The technique scheme of the utility model is compared prior art and is had the following advantages: when the recirculated cooling water automatic water-supply apparatus of the utility model is worked; Float floats on the water surface in the water tank by buoyancy, and the conductor ball of this moment places on the described pair of electrodes contact; When drawdown; Because the position basic fixed of said node, so float run-off the straight gradually break away from from described pair of electrodes contact until conductor ball; Thereby the power switch control loop that makes water pump records water level and is lower than setting value; Water on the control of pump, when float rose to setting height and said conductor ball and gets back on the described pair of electrodes contact, the control charging pump quit work.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the structural representation of the recirculated cooling water automatic water-supply apparatus among the embodiment;
Fig. 2 is the structural representation of the float among Fig. 1.
The specific embodiment
See Fig. 1,2; The recirculated cooling water automatic water-supply apparatus of present embodiment; Comprise: be located at the float 3 in the water tank 1, this float 3 comprises: hollow buoyancy aid 3-1, be located at the pair of electrodes contact 3-2 of this hollow buoyancy aid 3-1 bottom and alternate setting and be positioned over this to the conductor ball 3-3 on the electrode contact 3-2; Described pair of electrodes contact 3-2 links to each other with the water level signal input of the power on-off control circuit of charging pump; With lead that described pair of electrodes contact 3-2 links to each other on exist a node to be fixed in the water tank 1, or be connected with a counterweight 6 and place water tank 1; The conductor length between this node and the said float 3 and the water level higher limit of water tank 1 are corresponding.
As the embodiment of optimizing, the spherical in shape or olive shape of said hollow buoyancy aid 3-1.
Make said conductor ball 3-3 from space that described pair of electrodes contact 3-2 tumbles when having the contiguous said node of the water level that is suitable in water tank 1 in the said hollow buoyancy aid 3-1.
As the embodiment of optimizing, the inner wall smooth of said hollow buoyancy aid 3-1.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection domain of the utility model.
