| Spiral scales Screw feeder is mainly used for powder materials weighing, plus or minus 0.5% to plus or minus 1% accuracy, pre feeder can be connected spiral feeder, also can choose other forms of feeder. If only for weighing, can choose 6001 integrator, if you need to control function, need to select 6105 controller. |
| Weightlessness balance Precise feeding of loose materials is very important to keep the product quality, accurate and reliable weighing feeding can reduce material waste, improve ingredients continuity and improve efficiency.Weightlessness feeder even in demanding system can accurately control the material flow, regardless of the material is powder, granule, flake powder or particles. Zero gravity type feeder is suitable for liquid flow control and measurement at the same time. |
The working principle of
Through the static scale weighing complete feed system (bin, feeder, and material) and by variable speed motor or electric vibration machine control flow of discharging material.
Material (through the spiral, vibration pipe or tank) discharged from the system, each unit of time measurement of weightlessness and needed to quantificationally compare (the default), the flow of the actual (measured) and expectations of the difference between (the default) flow through feeding controller (FH - 4), the correct signal is the controller can automatically adjust the feeding speed, and in the absence of process lag keep accurate quantificationally.
When measuring the weight of the bunker to bin low level (to feed), the controller will feed control system according to the feeding volume, then the bin to quickly charge (manually or automatically), weightlessness controller action again.
In batch weighing weightlessness in the system, the design is similar to continuous gravity system, however, the feeding (bulk) and eventually weight precision is higher than the actual control of quantificationally.
FH - 04 controller by variable speed drive with high feeding signal in order to achieve rapid feeding, then switch to low feeding control signal for precise control at the end of the batch.
The characteristics of gravity feed system
Accuracy: + / - 0.25-1%
Weighing range: 0.01 - after 20 m/h
Is not affected by dust and material accumulation
Weighing the whole system, no belt tension or sliding error
There is no delivery time delay, to ensure the accuracy of the second to second
During normal operation can check the accuracy of the feed and does not need to take out the samples

| Electronic belt scale calibration device Electronic belt scale is equipped with a variety of calibration methods: Physical check device Physical check calibration of electronic belt scale is the most reliable way. Physical detection device works when the material on belt conveyor through electronic belt scale weighing junior people weighing hopper, after weighing the material by discharging device returns to the transmission system.Shown by the material object detection device and belt scale material weight are compared, so as to achieve the purpose of checking belt scale.In order to ensure the accuracy of the real object detection device, the device is equipped with standard weight, approval for its accuracy |
The furnace coal metering device
Boiling coal furnace microcomputer monitoring measurement system (FJX type) used the experience of design and manufacture of electronic belt scale, and the most advanced automatic control technology and method of the combination of industrial control computer with the rise and fall of coal plough device signal to complete the measurement points of each furnace furnace.The system has accurate measurement, less maintenance and the complete statistical reports, less modification cost, etc.
FJX points furnace measurement monitoring system optional type material level switch, complete automation (programmed) on coal.Before the coal on the computer screen to choose several coal coal, choose the right after the system will this a few coal sequence control of coal plough.Automatically on coal, without operator intervention.Some material level switch is used to control the coal on the coal bunker, coal overflow problem at the same time.
Such as at the bottom of the coal, the upper is equipped with rotary type or capacitive material level switch, to monitor the coal bunker coal level, at the same time using the computer accurately simulated coal bunker coal a state.
The working principle of
Belt scale used to measure the coal conveying belt of coal, into a computer;The belt scale and the coal flow between coal plough, memory by Ramsey flow records, computer;From coal plough device of the proximity switch signal, after the judgment which coal into coal, the traffic on the record of coal flow and belt scale of the storage of coal flow on the computer together get the coal bunker.Using this method to calculate the coal quantity, high precision and little error.
specification
Accuracy: + / - 0.5% (0.25% accuracy of belt scale), conform to the requirements of the ministry
The rated working voltage: 220 vac + 10% to 15%
Works: run continuously
Working environment temperature: - 10 - + 50 ° C

| Three meter hopper scale Three meter technology is applied to the capacity of the hopper scale can be from a few kilograms to hundreds of tons, weighing sensor can number 2, 3, 4, 6. Hopper scale is supported by four weighing sensor directly, weighing sensor is divided into four independent signals into the digital converter, digital converter converts weighing on the analog signal into digital signal transmitted to the weighing display.Weighing display through software combination operation form three sets of measuring value: a group of the main measurement values and the two groups of auxiliary measuring values. Main measurement value generated by the four weighing sensor measurement signal combination, auxiliary measuring value in the other two groups, respectively by A and B of the weighing sensor measuring signals, C, D weighing transducer as A fulcrum;C, D weighing sensor measuring signals, A, B weighing transducer as A fulcrum. Weighing normal display the main measurement value, at the same time two groups of auxiliary real-time online measurement value, if the second group of auxiliary measuring values vary too much, is beyond the scope of setting, are in group 2 Po measurement values of weighing sensor output signal respectively to compare, judge the faulty weighing sensor, both two groups a set of auxiliary measurement value of auxiliary trouble-free measuring value alternative, according to the main measurement values so as to ensure the hopper scale in a weighing sensor failure is still reliable for weighing.Greatly improve the reliability of the electronic hopper scale and the accuracy of the measurement.Avoided because of the weighing sensor failure, metering, causing great economic losses. |
