Abstract
A large power installation for water fed automatically of the utility model belongs to the technological improvement of the installations for water fed automatically. A tin bar is designed to be arranged in a water-tower or a water tank to be used as an electrode according to the characteristics of the large water power and the high delivery head of the large power pump making no use of the conduction method of a float or a keg float. The buffering starting of the motor windings of the large power water pump is realized by the adoption of a transistor ejection pole combining circuit and a Y-A conversion circuit, and the water shortage and overflow alarm is also equipped. The utility model has the advantages of simple device, safe using, resource saving, electricity saving, etc.
Description
The invention belongs to the technological improvement of water level automatic control device.
The water-supply apparatus of water tower in the past, water tank, reservoir and motor-pumped well generally all adopts ball float or keg float to bump the direct conducting of electrode.Its shortcoming is because moving melting point contact frequently with decide melting point, burns out the contact easily, and owing to being shifted or ball float contact reason such as get rusty, and cause loose contact, and it is feasible upward that water is inaccurate, and phenomenons such as lack of water, Shi Yi often take place.In addition, generally adopt the direct conducting starter motor of A.C. contactor, like this, can only be used for the motor below 10 kilowatts, because of starting current be normal operating current 7-8 doubly, cause the damage or the other accident of motor easily as frequent starting.So heavy-duty motor must be taked the reduced-voltage starting measure.For this reason, designed a kind of high-power automatic water-supply apparatus.
The objective of the invention is to solve the problem of water on the high powered water pumps such as water tower, water tank.
Fig. 1 is the schematic diagram of water tank.1 is the lack of water potential electrode among the figure, and 2 is that low water level electrode, 3 is the middle water level electrode, and 4 is high water level electrode, and 5 for overflowing level electrode.
Fig. 2-the 1st, the control section circuit diagram.
Fig. 2-the 2nd, the actuating section circuit diagram.
The present invention is that to utilize water be the characteristics of conductor, make the electrode thing and the water surface that are placed in the water carry out conducting according to situation about changing, cut-off, be fixed contact with the electrode that is placed in the water, the water surface is movable contact, the electrode that arranges in the water has: lack of water potential electrode (1), low water level electrode (2), middle water level electrode (3), high water level electrode (4), overflow their amongs of level electrode (5) one segment distance is arranged, and can adjust according to the height of water level of the water tank of installing or water tower the distance of electrode, the electrode that is placed in the water can adopt tin bar or stainless steel, is characterized in rustless, nontoxic, conduct electricity very well.
The automatic control section of water level:
Water level control automatically is by transistor BG
1And BG
2The emitter-coupled trigger of forming, when water level be lower than " in " during (3) point, be equivalent to power cathode and R
2Separately, BG
1Base stage lose bias voltage, end BG by saturated change
2Manage corresponding by ending change conducting, J
1Relay adhesive its normal battle of J
1-1Closure makes auxiliary reclay J
4Adhesive, its J of often making war
4-1Remove to connect the SJ time relay, make it adhesive.For A.C. contactor, to the action of a series of contactors, and form Y-△ switched conductive, the starter motor running in auxiliary reclay J adhesive.
When drawdown arrived " low " point (2), " low " point (2) separated with " lacking " point (1), promptly is equivalent to power cathode and resistance R
7Disconnect BG
3Pipe loses base voltage, is become by saturation conduction and ends, at this moment J
2Relay discharges, its normally closed some J
2-1Closure, the news Chinese percussion instrument sends low water stage and reports to the police.
The part of reporting to the police is by BG
3, BG
4Two pipes are realized.When water level reaches desired height, if line failure can not in time stop water pump and supply water, and water level still continues to rise, when reaching spill point (5), BG
4Be in control bias voltage, be equivalent to power cathode and resistance R this moment
11Connect relay J
3Adhesive its normal battle of J
3-1Closure, the news Chinese percussion instrument sends chimes of doom, simultaneously its normal opening and closing points J
3-2Open, auxiliary reclay outage is discharged, cut off the electricity supply, water pump stops to supply water.J wherein
4-4Node strings is at R
2And between the mid point water level, effect is to prevent the water pump frequent starting, and its strictness is controlled at water level between " high, in ".
Electric motor starting control is when water level control contact takes place, and begins action by auxiliary reclay, the time relay sj adhesive, and also adhesive simultaneously and self-locking of contactor 1C, 2C after the auxiliary reclay J adhesive, motor is connected into " Y " shape and carries out reduced-voltage starting.After treating that the electric motor starting electric current descends, time relay sj is fixed time and release immediately to giving, and contactor 2C outage is ended, and contactor 3C just can obtain electric adhesive, and at this moment motor is connected into " △ " shape, obtains full voltage and runs well.After the water level flop signal was cut outage automatically, contactor all discharged, and made the motor stall, just stopped to supply water.
This machine is adjustable to the Y-△ switching reduced-voltage starting of the electric motor starting employing of high-power running and the time length of normal operation; can finish by the time relay; within 5～120 seconds; can free adjustment control start-up time; change the detent torque of motor, and overload and no-voltage protection device are arranged.
The present invention starts big capacity pump motor---stop dependable performance, have simple in structure, easy to use, save the energy, advantage such as economical and practical.
10～30 kilowatts of The present invention is applicable to the motor of.
