The sharing frequency converter switching control device comprises a frequency converter, air switches, a contactor, a thermal relay, change-over switches, start and stop buttons, an indicator lamp and a cable, motor main loops of an acidification pump D1 and an acidification pump D2 are parallel and connected to terminal U, terminal V and terminal W of an BPQ output end of the frequency converter, the two motor main loops are respectively provided with the air switch Q2 and the air switch Q3 after being parallelly connected out from the BPQ output end of the frequency converter, a pump control power source Q21 and a pump control power source Q31 utilize alternating current 220V, an anode power source is respectively connected to lower ports of the air switch Q2 and the air switch Q3 of the two pump power sources, the positions are further provided with a three-position change-over switch GHK, two normally open contacts thereof are respectively serially connected among the control power source Q21, the control power source Q31, a stop button SB4 and a stop button SB6, a pair of normally closed contacts of a contactor KM2 is serially connected between a start button SB3 and a contactor coil KM1, and simultaneously, a pair of normally closed contacts of the contractor coil KM1 is serially connected between a start button SB5 and a contactor coil KM2.
Description
Technical field
The utility model relates to the switching control of the shared frequency converter of a kind of two pumps.
Technical background
Iron ore iron ore concentrate pipeline transfer ore pulp requires pH value usually between 10-11, otherwise the meeting corrosion pipeline influences its useful life, needs regulate pulp PH value by adding sour pump before entering pipeline for this reason.Generally there are two to add sour pump, working method is that a worker one is equipped with, but have only a pump to use frequency converter to control its flow size, in case this pump breaks down, the flow of stand-by pump can only be controlled by the manual adjustment valve, be difficult to control flow size like this, easily cause pulp PH value not in prescribed limit and corrosion pipeline, and the back operation is filtered moisture content control have a negative impact.
Summary of the invention
The utility model purpose is the deficiency that overcomes above-mentioned prior art, the shared frequency converter switching control that provides shared same the frequency converter of a kind of two pumps to control, also conveniently switch.
The utility model comprises frequency converter, air switch, contactor, thermal relay, change over switch, start and stop button, indicator light and cable; Two motor main circuits that add sour pump D1, D2 are arranged side by side, and directly receive on frequency converter B PQ output U, V, the W terminal, two motor main circuits are installed air switch Q2, Q3 respectively after frequency converter B PQ leading-out terminal picks out side by side simultaneously, move preceding two air switches in closed position, carry out two pumps and switch the preceding preparation that puts into operation at any time.Two pumps control power supply Q21 and Q31 adopt alternating current 220V, cathode power supply is connected to two pumps power supply air switch Q2 and Q3 end opening respectively, three-position switch GHK also is equipped with in this position, 3.-4., 5.-6. its two normally opened contact is serially connected with respectively between control power supply Q21, Q31 and stop button SB4, the SB6, spends the selection that rotation realizes which platform pump of operation in the two pumps by a left side 45 degree and right 45 of change over switch GHK handle.When the GHK handle was threaded to the centre position, 3.-4. and 5.-6. two normally opened contacts were not closed; When the GHK handle is threaded to a left side 45 ° the time, 3.-4. normally opened contact closure; When the GHK handle is threaded to right 45 °, 5.-6. normally opened contact closure.Between start button SB3 and contactor coil KM1, seal in a pair of normally-closed contact of contactor KM2; between start button SB5 and contactor coil KM2, seal in simultaneously a pair of normally-closed contact of contactor KM1; in the independent start and stop loop of two pumps, seal in the contactor normally-closed contact of the other side's pump so respectively; realize the interlocking of two pumps contacts of contactor, thereby realize that frequency converter only controls a pump operation simultaneously.
The utility model is imported three phase mains with an air switch and contactor adhesive to frequency converter, two pumps inserts inverter output terminal side by side, and insert two air switches and two contactor contacts between the motor respectively, three air switches often send during operation, start main contactor to frequency converter input 380V AC power, select any platform pump by selector switch again, start and stop the respective pump button simultaneously and make the contactor adhesive and disconnect the control pump running and stop, realizing adding acid with control start and stop of frequency converter panel and debugging knob and measure and be controlled in the prescribed limit.Protected the safe operation of main pump and concentrate pipeline, guaranteed to produce and carry out smoothly.Stablize the ore pulp characteristic, for filtering means dehydration creates conditions.
