Author: Smartweigh-Multihead Weighter

Nrog rau kev txhim kho ntawm kev nruam thiab meej metrological pov thawj tswj cov kev cai rau cov khoom siv raw, tshwj xeeb tshaj yog cov khoom siv raw, hom tshiab ntawm cov khoom siv ntsuas ntsuas——Lub xeev tsis muaj zog ntsuas ntsuas tshuab thiab khoom siv tau los ua hauv xyoo 1990. Lub multihead weighter tsis tu ncua thiab meej ntsuas cov khoom siv raw raws li qhov kev hloov pauv hauv qhov hnyav ntawm cov khoom siv raw ntawm lub ntsuas lub cev. Qhov tshwm sim ntawm multihead weighter maj mam hloov cov khoom siv hluav taws xob qub qub, kauv nplai thiab txawm tias tag nrho cov nplai.

Raws li txoj kev ntsuas tshiab thiab hloov kho tshiab, nws tau siv dav hauv kev lag luam metallurgical, mining, chemical plant thiab chemical fiber zog kev lag luam. Lub platform hnyav, pub rau hauv thiab tag nrho cov tshuab thiab cov cuab yeej ua haujlwm ntawm qhov kev pabcuam hnyav yog siv tag nrho lub cev hnyav, thiab lub sensor tsis tu ncua xa cov yuag hloov pauv ntawm lub cev hnyav mus rau ntau lub taub hau hnyav manipulator (lub manipulator yog tus yuam sij ntawm multihead weighter Ib feem ntawm kev daws teeb meem, txhua qhov kev tswj hwm thiab kev daws teeb meem yog ua los ntawm nws). Lub ntsuas ntsuas ntsuas ntsuas qhov ntsuas qhov hnyav elastic coefficient ntawm lub ntsuas lub cev hauv ib lub sijhawm raws li cov ntaub ntawv teeb liab raws li qhov tshwj xeeb tam sim no tag nrho ntws, thiab tom qab ntawd muab piv nrog cov teeb tsa tag nrho lub hom phiaj tag nrho ntws.

Tom qab PID xam, tso zis 4-50mA tam sim no cov ntaub ntawv teeb liab, hloov cov zis zaus ntawm lub cev muaj zog inverter, thiab tom qab ntawd hloov lub cev muaj zog sib piv, kom tus nqi pub mis tshwj xeeb yog ze li sai tau rau lub hom phiaj tag nrho cov dej ntws, yog li ntawd. raws li kom tiav qhov tseeb Lub hom phiaj ntawm pub. Txhawm rau kom ua tiav qhov kev noj zaub mov tsis tu ncua thiab ntsuas kev ntsuas qhov tseeb ntawm lub tshuab ua haujlwm ntau lub taub hau, lub hopper loj rau kev pub noj tsis tu ncua thiab lub siab tsis siv neeg lub valve rau kev pub mis noj yuav tsum tau teem rau ntawm qhov chaw pub mis. Muaj tus nqi txwv siab tshaj (recharge_terminated) thiab tus nqi qis dua (recharge_started) hauv qhov ntsuas ntsuas.

Thaum lub net hnyav ntawm lub teev nce mus txog qhov tsawg kawg nkaus tus nqi, lub teeb liab yuav raug xa mus qhib lub reloading valve, reloading valve yuav qhib, cov ntaub ntawv raw nyob rau hauv lub warehouse yuav raug txo mus rau lub loading rau hauv raws li cov conductive saj zawg zog kev twb kev txuas. , thiab qhov hnyav ntawm qhov ntsuas yuav nce.
