Chinoyera misoro yakawanda chinoshanda sei? (pfungwa)

Munyori: Smartweigh– Huremu hwemisoro yakawanda

Chiyero chemitsetse yakawanda muchina unoshandura simba rekinetic kubva kune imwe nzira kuenda kune imwe. Zvikuru sei, chiyero chemitsetse yakawanda isimba rinoshandura simba remakanika (senge simba rekutsigira, shrinkage, working pressure kana torque) kuita masaini emagetsi anogona kuyerwa nemazvo. Simba rekumanikidza rechiratidzo chedata rinoshanduka nesimba rekumanikidza resimba rekuburitsa.

Kune mhando nhatu huru dze multihead weigher zvichibva pachiratidzo chedata chinobuda: hydraulic, pneumatic uye resistance strain gauge. Rudzi rweweigher runonyanya kushandiswa mukugadzirwa kwemaindasitiri imultihead weigher ine built-in strain. Resistance strain gauge multihead weigher ine muviri wesimbi wakasimba (kana "elastic yellow component") inogadzirisa resistance strain gauge.

Imba yacho inowanzogadzirwa nearuminiyamu, simbi yekabhoni kana simbi isina ngura, zvichiita kuti ive yakasimba asi ine ductile zvakanyanya. Maitiro emuchina wekuyeresa une misoro yakawanda anochinja zvishoma kana chikero chikashandiswa, asi anodzokera kuchimiro chayo chepakutanga mukati, kunze kwekunge chiri mutoro. Kuti iite zviri nani pakupindura kuchinjwa kwechimiro chemuviri, resistance strain gauge inochinjawo chitarisiko chayo.

Izvi zvinokonzeresa kuchinja kwe resistance strain gage, iyo inogona kuyerwa nemazvo se operating voltage transition. Nekuti kuchinja kwakadaro mukubuda kwakabatana zvakanaka nehuremu hwese hunoburitswa, huremu hwese hwechinhu hunogona kuonekwa kubva pa operating voltage transition. Multihead weiger inoshanda sei? Kuti upindure kuti "Mumwe weigher weigher unoshanda sei?" unofanira kutanga wanzwisisa kuti "Mumwe weigher weigher unoshanda sei?" Mumwe weigher weigher mudziyo unoyera nemazvo kuchinja kwe resistor kana simba raburitswa.

Gaji rekudzivirira simba rinogara riripo rine waya yakapfava yefoil, yakaiswa muchimiro chegrid, zvichiita kuti resistor yesimbi ishanduke kana simba resimbi raburitswa pamwe chete. Kune mhando dzakasiyana dzegaji dzekudzivirira simba rekusarudza kubva padziri: Gaji rekudzivirira simba remutsara: Tambo yemagetsi yakabatana nekumashure kwegaji rekudzivirira simba iri yakafanana nemucheto wegaji rekudzivirira simba resimbi. Izvi zvinoshandiswa kuyera nemazvo radial strain nekukombama.

Mageji ekudzivirira kusimba kwekucheka: Tambo dzemagetsi dzakabatana kumashure kwemageji ekudzivirira kusimba dzakaiswa kumativi ese efuremu yekushanda iri padanho re45o. Izvi zvinoshandiswa kuyera kusimba kwekucheka nemazvo. Mageji ekudzivirira kusimba anowanzo shandiswa pamwe chete nehuwandu hwakawanda hwemageji ekudzivirira kusimba kwekucheka kuti zvive nani.

Imwe nzira yedigital power amplifier resistance strain gauge inonzi kota bhiriji, mbiri dzedigital power amplifier resistance strain gauges dzinonzi hafu bhiriji, uye ina dzedigital power amplifier resistance strain gauges dzinonzi full bridge. Kuchinja kwe resistor strain gage resistor hakuna kufanana nekurema bhatiri rinochajwazve musimba rinotsigira. Daro rekumanikidzwa kunoita kuti resistance strain gauge ive nyoro uye yakarebeswa, zvichisimudza resistor.

Simba rekusunga rinopfupisa ukobvu hwegauge yekumanikidzwa kwesimba uye rinoderedza kuramba. Gauge yekumanikidzwa kwesimba inosungirirwa kumusana mutete (fixed bracket), iyo inosungirirwa pakarepo ku weighing module, zvichiita kuti gauge yekumanikidzwa kwesimba inzwe simba rekumanikidzwa kwemuyero we multihead. Kuchinja kwe resistor kunoyerwa nemazvo negauge imwe chete yekumanikidzwa kwesimba idiki kwazvo, inenge 0.12°.

Kunzwa kwemutoro wemodule kunowedzera nenhamba yemageji ekustrain akaburitswa. Nzira yakanaka yekushandura shanduko iyi diki kuita chimwe chinhu chinofungidzika ndeyekubatanidza semabhiriji ekuyera akangwara. Mhando dzemageji ekustrain ekustrain Mageji ekustrain ekustrain akarongwa nenzira dzakasiyana, uye chokwadi chiri murudzi rwesimba rinoyerwa nemazvo.

Kukombama kwesimba, kuchekwa kwesimba, kumanikidzwa kweradial, torque uye kushanda nesimba zvese zvinoyerwa nemazvo uchishandisa nzira yakakosha yekuenzanisa magauge ekudzivirira simba. Dunhu reSmart weigh bridge rine ma resistors mana ekuenzanisa uye rinoshandisa voltage inoshanda inozivikanwa, sezvakaratidzwa pazasi: 5 ndiyo voltage inoshanda yakasimba inozivikanwa uye VO inoyerwa nemazvo. Kana ma resistors ese akaenzana, zvinoreva kuti R1/R2R3/R4 uye VO izero.

Kana paine shanduko mune imwe yemhando dze resistance, pachava neshanduko muVO, iyo inogona kuyerwa nemazvo uye kuratidzwa uchishandisa mutemo weOhm. Mutemo weOhm unosimbisa kuti huwandu hwemagetsi (I, muamperes) hunopfuura nemuchina wemagetsi pakati pemapoinzi maviri hune hukama hwakanaka nevoltage inoshanda (V) iri pakati pemapoinzi maviri. Resistor (R, inoyerwa nemazvo muohms) inounzwa setsananguro inoshanduka mukubatana uku uye haina chekuita nekuyerera kwemagetsi.

Mutemo weOhm unoratidzwa mufomura I=V/R. Kana ukashandiswa pamitsetse mina yemapepa eSmart weigh bridge power circuit, maequation anobuda ndeaya: Mumuchina we multihead weigher, resistance iyi inotsiviwa ne resistance strain gauge mukutsiva simba rekutsigira uye kuyerwa kwakarurama kwe shrinkage. Kana simba raburitswa kubhatiri rinochajwazve, ma resistor ari mu resistance strain gauge yega yega anochinja uye VO inoyerwa nemazvo.

Kubva paruzivo rwedata rwunobva, VO inogona kutsanangurwa zviri nyore uchishandisa sisitimu yekuenzanisa iri pamusoro apa.
