Description

A kind of full-automatic pumping control circuit

Technical field

The utility model relates to a kind of control circuit, specifically is a kind of industry that can be used for, agricultural and mineral products cause and various water tower, water tank, the full-automatic pumping control circuit that tanks such as boiler, wet pit and liquid container all can be installed and used.

Background technique

In the rural area of motor-pumped well for water, the perhaps tall building of hydraulic pressure deficiency, often will set up water tower or water reservoir, draw water with water pump, generally be knife switch or push-button switch to water pump control, opening or closing needs operator to carry out manual operations, this control mode wastes time and energy, in case and operator negligence appears, water is taken out full, water pump is also in the work that does not stop, thereby leads to the spilling water accident.In addition, if to arid season, groundwater recession takes place in the well when serious to dry up sometimes, and this moment, water pump can only be idle running, and took out not water outlet, worked on as water pump, not only waste energy, but also can be with infringement equipment itself.

The model utility content

In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of lack of water that realizes to draw water, the Automatic Control that water is completely shut down, and have simple in structurely, and cost is low, time saving and energy saving, energy-conserving and environment-protective, full-automatic pumping control circuit applied widely.

To achieve these goals, the technical solution adopted in the utility model is: a kind of full-automatic pumping control circuit, include motor, electronic switch, transformer, the relay A of tank, suction pump, the control switch of relay A is with after the motor of suction pump is connected, be connected on the ac power supply, it is characterized in that: the electromagnetic coil of described relay A, electronic switch also insert on the DC electrical source through forming after rectification, the filtering that the secondary winding by transformer provides described relay A relay B also in parallel with the form of serial connection; Be provided with the electrode of water level lower limit and the electrode of the water level upper limit in the described tank, the electrode of the water level upper limit is connected with the base stage of electronic switch, the lighting outlet of the electrode of water level lower limit links to each other with two contacts of the normal open switch of relay B with the lighting outlet of the electrode of the water level upper limit, and the bottom of described tank also is provided with a power electrode.

Described tank is water tower or water tank or boiler or wet pit or liquid container.

The ac power supply electrode of described power electrode for being connected with ac power supply.

The beneficial effects of the utility model: owing to be provided with the spacing up and down of water level in the tank; can guarantee tank hydraulic pressure normal water supply; can draw water automatically during lack of water, when water is full, autostop; need not labor management; automatically the application of pumping control circuit is not only time saving and energy saving, and has effectively prevented the generation of spilling water accident; prolong the working life of pumping equipment, but also saved the energy greatly.The utility model also has simple in structure, low, the advantage of wide range of application of cost.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is an electrical schematic diagram of the present utility model.

Among the figure: 1, tank; 2, motor; 3, electronic switch; 4, transformer; 5, relay A; 6, relay B; 7, the electrode of water level lower limit; 8, the electrode of the water level upper limit; 9, power electrode.

Embodiment

As shown in Figure 1, a kind of full-automatic pumping control circuit, include motor 2, electronic switch 3, transformer 4, the relay A 5 of tank 1, suction pump, the work of the control switch of relay A 5 and the motor that is connected on ac contactor coil control suction pump or stop, be connected on the ac power supply, it is characterized in that: the electromagnetic coil of described relay A 5, electronic switch 3 insert on the DC electrical source through forming after rectification, the filtering that the secondary winding by transformer 4 provides with the form of serial connection, described relay A 5 relay B 6 also in parallel; Be provided with the electrode 7 of water level lower limit and the electrode 8 of the water level upper limit in the described tank 1, the electrode 8 of the water level upper limit is connected with the ground level of electronic switch 3, be provided with the normal open switch of relay B 6 between the lighting outlet of the electrode 7 of water level lower limit and the ground level of electronic switch 3, described tank 1 is a water tower, also be provided with an ac power supply electrode 9 in its bottom, the lighting outlet of this electrode is connected on the described DC electrical source.Not corroding electrode in the ac electrode water receiving tank is because direct current corrosion is strong.

Working principle:

Because the control switch of relay A 5 is made as normally closed switch, when in the water tower when anhydrous, relay A 5 normally closed switching on reach 380 volts of ac contactor coil work, the driven by motor water pump draws water to water tower, water in water tower arrives the water level upper limit, when contacting with the electrode 8 of the water level upper limit, because the bottom of water tower is provided with an ac power supply electrode 9, at this moment, electrode 8 is a high level, thereby electronic switch is with circuit turn-on, relay A tripping operation, motor quits work, meanwhile, the normal open switch closure of relay B, the electrode 7 of water level lower limit is linked to each other with the ground level of electronic switch, when people constantly make water, when making the drawdown in the water tower, although water in the tower and the electrode of the water level upper limit 8 break away from, motor can not drive water pump and start working, because the electrode 7 of water level lower limit is positioned in the water, electrode 7 by the water level lower limit provides high level for electronic switch, thereby make relay in running order always, make motor keep halted state, water in tower falls back to the position of water level lower limit, when the electrode 7 of water and water level lower limit was separated, the electrode 7 of water level lower limit was for electronic switch provides low level, thereby circuit is disconnected, the magnetic of relay A and relay B disappears, make the normally closed switch of relay A reset to 380 volts of ac contactor coil energisings of closed state work again, motor begins to drive water pump and draws water in tower, meanwhile, the normal open switch of relay B resets to off state again, the electrode 7 that makes the water level lower limit disconnects with the ground level of electronic switch, even the electrode 7 of water level lower limit is with after water contacts, and the generation high level, can not pass to electronic switch, make electronic switch be in off state.Water in tower rises gradually, rises to when contacting with the electrode 8 of the water level upper limit, repeats aforementioned activities, goes round and begins again, and realizes that water begins to draw water the purpose of the Automatic Control that water stops pumping completely automatically less.

Mine water level controller working principle is basic identical with full-automatic water pumper circuit; just change relay A5 normally closed switch; utilize the normal open switch leading-out wire of relay A5, control 380 volts or 220 volts of ac contactor coil work and drive pump motor and draw water or shut down.Just only the electrode wire in the electrode 7 of water level lower limit, the electrode 8 of the water level upper limit, 9 three containers of power electrode being put in the mine water can the control of pump proper functioning.
