Description
Technical field
The present invention relates to a kind of concrete batching scale load calibration methods.
Background technique
Burden balance are a kind of more special weighing apparatus, it is by previously given mass ratio, to by several objects in title object
The weighing apparatus of matter progress batching metering.Concrete batching scale is by automatic weighing mode, and by different bulk materials, (concrete is former
Material: aggregate, cement, water and additive etc.) synthesize the concrete of predetermined quality and secure fit ratio.The weighing of burden balance
Principle is the quality of object to be determined using the gravity acted on scale hooper, that is, the power that quality of material converts is passed through survey
Device survey calculation is measured, then variable is shown with mass unit.
Concrete batching scale mainly includes one or more weighing units, and each weighing unit presses corresponding material
Progress quantita-tive combinations are accumulative after carrying out quantitative weighing according to preset ratio, are finally stirred output concrete.General concrete is matched
Material system includes the burden balance of four seed types: aggregate, cement, water, additive, the admixtures scale such as special increase flyash.Class
As include weighing (control) system with automatic (quantitative) ingredient such as concrete batching and mixing tower, asphalt mixing building and proportioning machine
Equipment.Universal with commerical ready-mixed concrete, concrete batching scale is widely used in all kinds of building trades in China, and burden process
It is the key link produced in Concrete, directly affects the performance and quality of concrete.The basic device and core of ingredient
It is exactly burden balance.Burden balance metering it is accurate whether be just particularly important.Currently, the calibrating for concrete batching scale does not have also
There is special national verification regulation.The characteristics of for burden balance, need to carry out static verification and dynamic calibration simultaneously, referring to country's inspection
It establishes rules journey JJG539-1997 " digital indication scale " (static verification), JJG564-2002 " gravity type automatic charging weighing apparatus " (dynamic
Calibrating) some areas have write provincial standard such as: JJG (Zhejiang) 96-2007, JJG (Shandong) 66-2008, JJG (Fujian) 1040-2011.
But static verification still uses standard test weight as standard in all kinds of calibration methods, and concrete batching scale has due to hopper space
Effect, is not available big counterweight, and miniweights put it is time-consuming and laborious；Dynamic calibration is examined and determine using material, but the handling number of material
It at least wants as requested 10 times, it is also labor intensive.As for now widely used HZS120 type burden balance, it has 4
Maximum weighing can reach (3000~5000) kg. and also reach 2000kg or more in actual use, and in addition there are also 4 other scales, such as
Cement weigher, flyash, water scale, additive scale etc..Once 25kg standard test weight at least needs 300 times or more static verification up and down；
Dynamic calibration examines a common movable loading point if every platform balance, is calculated with 8 platform balances, to fill 80 materials, both can not find so
More materials, it is also desirable to spend a large amount of manpower and material resources.
In conclusion enterprises and institutions require increasingly the calibrating of concrete batching scale with economic rapid development
Height, traditional standard method is difficult to accomplish that full scale is examined and determine, and work consuming effort.
