Abstract
The utility model relates to the automatic control device of a bittern pump. The existing device makes use of bittern to conduce, and electrodes are put in the bittern to control circuits, but the bittern corrodes the electrodes, so the lifetime of the electrodes is short; an electrode support attaches to the bittern, which can wrongly conduce. The automatic control device of a bittern pump comprises a support, pull wires, floats, a pulley, and the triggering cylinder of circuits, wherein, pull rods for connecting with the pull wires are arranged in the triggering cylinder of circuits; upper contact pieces, lower contact pieces, and balancing weight blocks are arranged on the pull rods; the upper and the lower parts of the triggering cylinder are respectively provided with an upstroke switch and a downstroke switch. The floats and a stopping cylinder use anti-corrosive plastic pieces to control the circuits not to conduce by the bittern; the automatic control device of a bittern pump is not influenced by corrosion, and the working state is stable and safe.
Description
The utility model relates to a kind of automatic controller of electric water pump, the automatic controller of the electric water pump of using especially for saltern allocation and transportation bittern.
The existing automatic controller that is used for the electric water pump of saltern allocation and transportation bittern is the electric conductivity that utilizes bittern, places pair of electrodes in water inlet place of water pump, when the extremely certain water flooding electrode of bittern, connects circuit, starts water pump.Electrode breaks away from bittern when bittern has been beaten, and can cut off the electricity supply the machine in case water pump fans the air automatically.But the shortcoming of this control mode is because of electrode will lean on the bittern conduction, and the corrosivity of bittern is very strong, adds electrolysis accelerated corrosion electrode, makes the life-span of electrode very short.In addition, because the damp-suction of bittern is very strong, sometimes, bittern has been beaten dried, still adheres to the very thin bittern of one deck on the electrode suppor, makes electrode still keep on state.And the concentration difference of bittern, electric conductivity is also different, can produce misoperation when controlling with light current.
The utility model has proposed a kind of float type automatic controller of electric water pump at the deficiencies in the prior art.
Task of the present utility model is to realize like this, the utility model is a kind of automatic controller of electric water pump, partly form by water level triggering part, control circuit, the water level triggering part comprises float, pulley and the circuit triggers tube of support, band backguy, there is one can move up and down and the upper end is connected in pull bar in the backguy in the circuit triggers tube, be installed with contact, following contact, balancing weight on the pull bar, the upper stroke switch of may command circuit is housed on the top of circuit triggers tube, and the lower stroke switch of may command circuit is equipped with in the bottom.Also be equipped with on the support and can limit the flow isolating cylinder that float swings, the upper base of flow isolating cylinder leaves exhaust port and backguy hole, and going to the bottom is open type.Last contact in the circuit triggers tube, following contact are to slide on pull bar and orientable contact.Timer and manual normally closed switch TA are equipped with in series connection in the control circuit
1, upper stroke switch CK
1, lower stroke switch CK
2, lower stroke switch CK
2The two ends parallel connection contact C of A.C. contactor is housed
4With manual enable switch QA
1, timer and manual normally closed switch TA
1And manual enable switch QA
1All be arranged on control close in.
The utility model compared with prior art because float and flow isolating cylinder can be selected cheap etch-proof working of plastics for use, control circuit is not conducting medium with bittern, circuit part is not subjected to the influence of environmental corrosion away from bittern; Again because of the float of measuring water level has adopted flow isolating cylinder, so the influence that float is not flowed by bittern is not subjected to the influence of floating foreign material and wave in the bittern yet, stable working state can not produce misoperation; And regulate two contact distances, the preceding water-head of start can be adjusted, to be fit to different usage requirements; And replenish with timer and manual cooperate control mutually with float, selectable range is big; Whole installation cost is low, and is safe and reliable, easy to maintenance.
Fig. 1 is the structural representation of the utility model water level triggering part.
Fig. 2 is the circuit diagram of the utility model control circuit.
Fig. 1, Fig. 2 are an embodiment of the present utility model, below in conjunction with accompanying drawing, further describe.Task of the present utility model is to realize like this, the utility model is the automatic controller of a kind of electric water pump (14), by the water level triggering part, control circuit is partly formed, the water level triggering part comprises support (4), the float (1) of band backguy (3), pulley (5) (6) and circuit triggers tube (13), there is one can move up and down and the upper end is connected in pull bar (8) in the backguy in the circuit triggers tube (13), be installed with contact (9) on the pull bar (8), following contact (11), the balancing weight of constant weight (10), the upper stroke switch (7) of may command circuit is housed on the top of circuit triggers tube (13), and the lower stroke switch (12) of may command circuit is equipped with in the bottom.Also be equipped with on the support (4) and can limit the flow isolating cylinder (2) that float (1) swings, the upper base of flow isolating cylinder (2) leaves exhaust port and backguy hole, and going to the bottom is open type.Last contact (9) in the circuit triggers tube, following contact (11) are can go up at pull bar (8) to slide and orientable contact.Timer (15) and manual normally closed switch TA are equipped with in series connection in the control circuit
1, upper stroke switch CK
1, lower stroke switch CK
2, lower stroke switch CK
2The two ends parallel connection contact C of A.C. contactor is housed
4With manual enable switch QA
1, timer and manual normally closed switch TA
1And manual enable switch QA
1All be arranged on control and close in (16), upper and lower stroke switch is contained in and triggers in the tube (17)!
Like this, the main switch that at first closes is opened timer, circuit is in preparatory work dress attitude, and when water pump water inlet place water level rose, float rose, pull bar descends under the effect of balancing weight, and when water level reached predetermined altitude, the following contact on the pull bar compressed lower stroke switch CK
2, control wiring is connected, the AC coil energising, and water pump begins to start operation.Float descends thereupon when drawdown, and contact left lower stroke switch under pull bar rose, and lower stroke switch disconnects, but the contact C of A.C. contactor
4Still closed, water pump is still worked, and when water level is reduced to predetermined shutdown water level and timing does not arrive, presses position limit switch CK on the last contact of pull bar
1, upper stroke switch disconnects, the A.C. contactor outage, and water pump quits work.If arrival timing, timer disconnect water pump and also quit work.After water pump stopped, water level was higher than the shutdown water level, was lower than the start water level need start shooting the time, pressed hand switch QA
1Starting water pump gets final product; When needing artificial the shutdown midway, press hand switch TA
1Get final product.
