Abstract
The utility model discloses a drainage box water feeding device, which comprises a drainage box and a water feeding pump. The water feeding pump is connected with a water feeding pipe of the drainage box, the liquid level sensor is mounted on the drainage box and electrically connected with an electric control circuit, the electric control circuit includes a middle relay branch, a time relay branch and a water feeding pump contactor branch, the middle relay branch is controlled by the liquid level sensor, the time relay branch is controlled by a contact of a middle relay, and the water feeding pump contactor branch is controlled by a contact of another middle relay. After the technical scheme is adopted, the liquid sensor can convert the height of liquid level into electric signals, the electric signals automatically, timely and rapidly control start and stop of the water feeding pump by the aid of the electric control circuit, and overflow of saline is prevented. The drainage box water feeding device is sensitive in response and can effectively save labor cost.
Description
Technical field
The utility model relates to the preceding drain tank of a kind of steam turbine, relates in particular to a kind of water-supply apparatus of drain tank.
Background technique
The drain tank water-supply apparatus is generally and manually goes up water before the steam turbine, liquid level in finding drain tank is higher, the operator removes to open charging pump immediately, can be too far away at interval because of operating room, when charging pump was opened, drain tank is spilling water, cause the waste of a large amount of demineralized waters, therefore, be badly in need of a kind of device and can monitor liquid level automatically, and can in time open water on the charging pump.
The model utility content
Technical problem to be solved in the utility model provides a kind of drain tank water-supply apparatus that can control automatically.
For solving the problems of the technologies described above, the technical solution of the utility model is: the drain tank water-supply apparatus comprises, drain tank, with the charging pump that described drain tank water inlet is connected, on the described drain tank liquid level sensor is installed, described liquid level sensor is electrically connected with electric control loop.
As optimized technical scheme, described electric control loop comprises an auxiliary reclay branch road by described liquid level sensor control, article one, by the contact triggered time relay branch road of described auxiliary reclay, a contact triggered charging pump contactor branch road by described auxiliary reclay.
After having adopted technique scheme, the beneficial effects of the utility model are: described liquid level sensor can be converted into electrical signal with liquid level, described electrical signal is in time controlled the start and stop of charging pump automatically rapidly by described electric control loop, prevents that demineralized water is excessive.The utility model is quick on the draw, and can effectively save human cost.
Description of drawings
Accompanying drawing is the utility model embodiment's a electrical schematic diagram;
Among the figure: the SB1-stop button; The SB2-start button; SQ-liquid level sensor signal; The KA-auxiliary reclay; The KM-contactor; The KT-time relay; The FR-hot protective relay.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.
Embodiment: the drain tank water-supply apparatus comprises, drain tank, with the charging pump that described drain tank water inlet is connected, liquid level sensor SQ is installed on the described drain tank, described liquid level sensor SQ is electrically connected with electric control loop.
As shown in drawings, described electric control loop comprises an auxiliary reclay KA branch road by described liquid level sensor SQ control, article one, by the time relay KT branch road of the normally opened contact of described auxiliary reclay KA control, a charging pump contactor KM branch road by the normally opened contact control of described auxiliary reclay KA.
The working principle of described electric control loop is: when sensor signal contact SQ closure, perhaps press start button SB2, auxiliary reclay KA gets electric self-sustaining, KA normally opened contact closure, contactor KM closure, water on the charging pump, the closed beginning of time relay KT simultaneously regularly, timing arrives, KT contact Time Delay Opening, KA outage.If timing does not arrive, press stop button SB1, the KA outage, the KA normally opened contact resets, KM, the KT outage, charging pump stops.
In the utility model, owing on the drain tank liquid level sensor is installed, described liquid level sensor can turn to electrical signal with liquid level signal dress, electric control loop can be controlled automatically by the electrical signal of liquid level sensor, avoided operator on duty carelessness or when leaving, drainage pump is not in time opened, and causes the excessive situation of demineralized water to take place.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the drain tank water-supply apparatus comprises, drain tank, and the charging pump with described drain tank water inlet is connected is characterized in that: on the described drain tank liquid level sensor is installed, described liquid level sensor is electrically connected electric control loop.
2. drain tank water-supply apparatus as claimed in claim 1, it is characterized in that: described electric control loop comprises an auxiliary reclay branch road by described liquid level sensor control, article one, by the contact triggered time relay branch road of described auxiliary reclay, a contact triggered charging pump contactor branch road by described auxiliary reclay.
