失重秤
Weight loss scale
 
       失重秤是一種連續(xù)給料的稱重設備，由于失重控制在料倉中進行，可達到較高的控制精度。該系統(tǒng)給出料倉過程為密封結(jié)構(gòu)，環(huán)保無污染，廣泛應用于冶金、建材等微粒粉末物料的輸送計量的控制。
1、失重秤計量原理稱重料倉和稱重給料螺旋安裝在一起，形成料倉總成，該總成放置在稱重傳感器總成上，組成一個單獨的計量裝置，通過進、出物料軟連接，使料倉總成與支承結(jié)構(gòu)隔離，料倉的重量接受計量摔制系統(tǒng)的監(jiān)視和控制。失重給料摔制系統(tǒng)將根據(jù)料倉總成的重量的減少，連續(xù)計算出投料暈，并將該投料暈與設定值進行比較，控制螺旋的速度，保證投料罩與設定值相同。投料控制連續(xù)工作，直到稱重料倉總成的重量達到預設定的下限設定值。達到下限設定值時，稱重倉上面的加料閥將自動打開，向稱重料倉進行加料，加料系統(tǒng)將保持給料狀態(tài)，直到稱重倉總成的重暈達到預設定的上限設定值，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)組成失重秤由進料系統(tǒng)、料倉總成、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
