2. device feature is few, simple to operate, and maintenance is little, and few easy workout part is not high to maintainer's competency profiling, and common electrician, universal machine maintenance mans implement maintenance under can instructing at producer technician's phone;
3. production cost is low, safeguards that simply use cost is low, and reliability is high, and the life-span is long, has quite high promotional value.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
As shown in Figure 1, the invention discloses the water distribution control device of weighing that a kind of brick-tile industry is used, comprise Weighing module, electric control module and water supply module;
Wherein, Weighing module comprises electronic load cell and weighing-up wave amplifier;
Electric control module comprises power supply, the first potentiometer R1, the second potentiometer R2, frequency converter;
Described power supply is connected with LOAD CELLS, weighing-up wave amplifier respectively, the low pressure end of described the first potentiometer R1, high-pressure side are connected with power supply, output terminal respectively with the second low pressure end of potentiometer R2, the GND of frequency converter end is connected, the high-pressure side of described the second potentiometer R2 is connected with the output terminal of described weighing-up wave amplifier, output terminal is connected with the input end of frequency converter external command frequency signal;
Water supply module comprises water pump, and the motor of described water pump is connected with the lead-out terminal of described frequency converter.
As a kind of further prioritization scheme of water distribution control system of weighing of the present invention, described power supply Wei Er road output direct-current switch power supply, wherein a road is exported and is connected with weighing-up wave amplifier with LOAD CELLS respectively, and another road output is connected with the first potentiometer R1.
It is all the convenience of the simulating signal of this same type of direct current 0～10V that this device utilizes the external command frequency signal of weighing-up wave and frequency converter, use 2 potentiometers (slide rheostat), i.e. the first potentiometer R1 and the second potentiometer R2, directly weighing-up wave is converted to the operating frequency signal of frequency converter, realized calculating and just reach the object of following the tracks of in time water distribution with the instantaneous weight of principal goods material.
This device be according to the instantaneous weight of principal goods material and whether reinforced actuating signal decide synchronously add that hydrodynamic(al) does from dynamic control device, without staff on duty, can will for eletric starter button, be arranged on union operation on the operator's console of main post work.Cabinet face is only provided with the pilot lamp HL1 that powers on, solenoid valve YV conducting pilot lamp HL2, the control of amount of water provides basis signal by weighing-up wave, the command switch K that whether adds water synchronously determines (being also interlocking) by the reinforced action of principal goods material, separately establish SA-2, be convenient to debugging and maintenance etc. and initiatively cut off water route and frequency converter work.The weight of principal goods material obtains by the electronic load cell of installing, then converts 0～10V direct current signal to through signal amplifier.From deserving to be called the weight resultant signal that the weight signal of acquisition is subordinate mechanism and principal goods material, subordinate mechanism is generally belt conveyor.When equipment does not add the idle running of principal goods material, we are called the deadweight of subordinate mechanism or tare weight, deserve to be called still and can be subject to certain power, can produce corresponding Voltage-output.We are transferred to maximum value point by the sliding point of the second potentiometer R2, and the first potentiometer R1 is transferred to minimum resistance point, and now on the nixie display of frequency converter, shown frequency number becomes certain proportionate relationship with above-mentioned voltage.Indirectly know in other words voltage.And now require water pump not turn or amount of water is zero, substantially constant to the mounted subordinate mechanism weight of specifically weighing.Now just can be by regulating a DC voltage of adjustable contact output of the first potentiometer R1 carry out this analog voltage of balance, near equilibrium point the displayed value of frequency converter in zero left and right, each several part work while reaching dry run but do not add water.
In actual production, the contained moisture time of principal goods material self has been grown also and can change, each producer of the water percentage of production requirement may be not identical yet, this just requires water addition ratio example adjustable, in design, by the second potentiometer R2, the nt wt net weight signal of principal goods material being carried out to certain ratio regulates, signal after adjusting is controlled the frequency of operation of frequency converter again, all the time guarantee that adding hydrodynamic(al) working frequency becomes certain proportionate relationship with principal goods material instant cleaning liquid weight signal, further reach the object of controlling suitable amount of water.
After frequency converter powers on, element task program is opened.Detect on the one hand the voltage signal of the external command operating frequency size between AI1 and bis-points of GND, after by nixie display, show pre-operating frequency number.Wait on the other hand working signal (COM and FWD conducting).On this path, be provided with SA-1 and force on-off switch, the conveying arrangement of another and principal goods material has been implemented electric interlock.
