For by the analytical tool of weight difference before and after mensuration example reaction, it is both needed to dress sample container (such as crucible, beaker etc.) and sample are weighed respectively before example reaction, i.e. needs to carry out twice weighing stage.
Routine weighing flow process is: first weigh dress sample container (such as crucible, beaker etc.)；In dress sample container, add sample again, weigh sample and the weight of dress sample container (such as crucible, beaker etc.)；Finally by being calculated example weight.That is:
As it is shown in figure 1, coal sample is carried out moisture and the application process of ash analysis detection for existing weighting manner in automatic industrial analytical tool.Idiographic flow is:
S1: place all crucibles；
S2: balance of weighing resets；
S3: sample dish declines, and weighs the weight of current crucible, is denoted as M0, sample dish rises；Rotate to next bushing position, operate successively, until all crucibles are weighed；
S4: rotate at first sample position, sample dish declines, and to weighing, balance resets, and places sample, and the weight weighing sample is M1, sample dish rises；Rotate to next bushing position, operate successively, until all crucibles are weighed；
S5: the M obtained by weighing0And M1, participate in the calculating of index.
Have in the instrument of multiple sample test at the same time, use conventional flow process of weighing, after each shuttle (such as crucible, beaker etc.) need to being weighed respectively, then add sample one by one；The most respectively the container after adding sample is weighed, be finally calculated the actual weight of each sample.
In existing instrument and equipment, weigh dress sample container (such as crucible, beaker etc.) and sample, can be by weighing manually and instrument automatic Weighing realizes.As used the artificial manual mode weighed, this is accomplished by weighing each dress sample container (such as crucible, beaker etc.) and sample respectively, the most also needs to carry out the operation of twice weighing stage, and when sample size is more, manual steps is more, and the operating time is long.As used the mode of instrument automatic Weighing, test sample need to be changed by conversion sample on-position or rotation sample dish.But, in existing instrument and equipment, generally using motor drives sample dish to realize the conversion of sample position, it is required to start a driving means every time after weighing and is transformed into next sample position, it is longer that this conveying transformation process expends the time, especially when sample number is more time, the conveying conversion time is long, eventually has influence on Instrumental Analysis testing efficiency.It addition, the most general automatic Metage Eguipment is all to support sample dish by a sample weighting rod to complete to weigh operation, in the transformation process repeatedly weighed, it is easy to the problem producing off-centring of weighing, weighing precision impacts.Specifically, have the disadvantage that
1, during twice weighing, owing to industrial analysis instrument weighing room environment is unstable, the possible gap of other factors such as the ambient temperature of twice weighing, humidity is relatively big, and the accuracy of weighing has certain uncertain impact.
2, in the Industrial Analysis instrument of automatic Weighing, commonly used balance connects push rod and weighs weight, the method being dropped to realize on push rod weighing reading by rotating disk or manipulator control crucible during weighing.In such Weighing system, owing to selecting disc spins or mechanical hand running accuracy error when repeatedly weighing, rising or falling speed and the diversity in direction, may cause the center of gravity of placed crucible to be varied from every time, and impact weighs the moment of balance thus produces weighing error.
3, owing to, in Weighing system, weighing and being required for carrying out last result the revision of the convention every time, unnecessary weighing number of times will increase the cumulative error that the revision of the convention brings, and has influence on weighing precision.
