失重秤
Weight loss scale
 
       失重秤是一種連續(xù)給料的稱重設(shè)備,由于失重控制在料倉(cāng)中進(jìn)行,可達(dá)到較高的控制精度。該系統(tǒng)給出料倉(cāng)過(guò)程為密封結(jié)構(gòu),環(huán)保無(wú)污染,廣泛應(yīng)用于冶金、建材等微粒粉末物料的輸送計(jì)量的控制。
1、失重秤計(jì)量原理稱重料倉(cāng)和稱重給料螺旋安裝在一起,形成料倉(cāng)總成,該總成放置在稱重傳感器總成上,組成一個(gè)單獨(dú)的計(jì)量裝置,通過(guò)進(jìn)、出物料軟連接,使料倉(cāng)總成與支承結(jié)構(gòu)隔離,料倉(cāng)的重量接受計(jì)量摔制系統(tǒng)的監(jiān)視和控制。失重給料摔制系統(tǒng)將根據(jù)料倉(cāng)總成的重量的減少,連續(xù)計(jì)算出投料暈,并將該投料暈與設(shè)定值進(jìn)行比較,控制螺旋的速度,保證投料罩與設(shè)定值相同。投料控制連續(xù)工作,直到稱重料倉(cāng)總成的重量達(dá)到預(yù)設(shè)定的下限設(shè)定值。達(dá)到下限設(shè)定值時(shí),稱重倉(cāng)上面的加料閥將自動(dòng)打開,向稱重料倉(cāng)進(jìn)行加料,加料系統(tǒng)將保持給料狀態(tài),直到稱重倉(cāng)總成的重暈達(dá)到預(yù)設(shè)定的上限設(shè)定值,此加料系統(tǒng)將關(guān)閉,開始新的失重控制周期。
2、失重秤的結(jié)構(gòu)組成失重秤由進(jìn)料系統(tǒng)、料倉(cāng)總成、稱重傳感器、螺旋給料系統(tǒng)、空氣平衡系統(tǒng)和控制系統(tǒng)等部分組成。

Weightlessness steelyard is a continuously for material weighing device, due to loss of weight control in the silo is. higher control accuracy is achieved The system gives bin process for sealing structure. environmental protection, no pollution, widely used in metallurgy, building materials. such as the particles of powder material conveying and metering control
1 , weight loss scale measurement principleWeighing hopper and a weighing to spiral installed together, forming silo assembly, the assembly is placed on the weighing sensor assembly. a separate metering device Is composed. through an inlet and a soft material connection The bunker assembly and isolation of supporting structure, the weight of storehouse accept metering control sVstem monitoring and control. WeighTlessness feeding control system will according to the bin weight reduction, continuous calculated feeding amount. and the feeding value and the set value is compared. spiral control speed. ensure feeding volume and setting values are the same Feed control of confinuous work. unfU the assembly weight weighing hopper reaches its limit preset value Lower reaches the set value, weighing chamber above the charging valve will automatically open to a weighing hopper charging. the charging system will keep state. until the weighing bin assembly weight reaches a preset limit setpoint. the dosing system will shut down and began to new weightlessness control cvcle
