Background technology
Belted electronic balance is the ideal equipment for carrying out continuous metering in belt conveyor system to loose unpacked material, belted electronic balance
Have many advantages, such as it is simple in structure, weigh it is accurate, using stabilization, easy to operate, maintenance is few, extensively should should be in metallurgy, electric power, coal
The industries such as charcoal, mine, harbour, chemical industry, building materials, however also there are many problems in actual application in belt conveyer scale, dynamic
Metering has large error always compared with static weighing, how to reduce dynamic measuring error this little problem always
It is not well solved, to find out its cause, the predominantly following：
1. the effect precision and service precision of belt conveyer scale
International Legal Organization at present（OIML）The highest accuracy of the regulation of R50, belt conveyer scale is 0.5%.Home products was once
0.25% class of accuracy is proposed, but in actual use, this accuracy is extremely difficult to, finally in 2008
In GB/T7721-2008, integrate with international accuracy, with 0.5% for highest class of accuracy；
But the accuracy claimed with bucket（It is roughly equivalent to 0.1%）It compares, the error of belt conveyer scale is very big, makees in certain industries
For trade settlement, this accuracy is not acceptable.So the accuracy of belt conveyer scale should improve；
Actually only it is that 0.5% accuracy of measuring is also required to a large amount of manpower, material resources, the maintenance ability made nothing of hardships daily
Access guarantee.So that user puts into great effort in the daily maintenance of belt conveyer scale.
2. belt tension changes
Crane span structure of weighing equipped with load transducer is installed on the longeron of conveyer by conventional belt scale, the title weighed on crane span structure
Great trust roller detects the weight of material on belt, generates an electrical output for being proportional to belt load.Velocity sensor is straight
It connects and is associated on driven roller or on the carrying roller of major diameter, a series of pulses are provided.Integrator is passed from load transducer and speed
Sensor receives output signal, and electronically belt movement is multiplied with belt load, by the calculating to the time, generates one
Instantaneous flow value and accumulative gross weight.Accumulative gross weight is converted into selected engineering unit with instantaneous flow, shows over the display respectively
It shows to come.It is understood that belt conveyer scale is exactly to carry out weight to the material by metering section during belt-conveying to add up, belt
Scale is mounted under belt, and material is on belt conveyor, and belt is as transmission medium between belt conveyer scale and material.Belt
As material paves the variation of the uniformity, the variation of humiture, belt tension also constantly changes, since belt conveyer scale can not be direct
Material is weighed, so the variation of belt tension directly affects the accuracy of weight of material transmission, leads to belt scale metering error,
Long-time stability cannot be guaranteed.
