1. Nhanganyaya yeChigadzirwa
Mita yemazinga eLMU akatevedzana eultrasonicmudziyo wekuyera wakabatana une waya mbiri wakatangwa neLanry Instruments. Une sensor yeprobe yakabatana uye unit yemagetsi yekugadzirisa ine chimiro chakavharwa chose chinodzivirira kubuda kwemvura, zvichiita kuti zvinwiwa nezvinhu zvakasimba zvirambe zvichiongororwa nguva dzose. Zvakakodzera mamiriro akaoma ekushanda musimbi, makemikari, magetsi, peturu nedzimwe nzvimbo, chigadzirwa ichi chinotsigira screw neflange mounting. Ichitora musimboti wekuyera nguva yekubhururuka, ine automatic tembiricha compensation uye intelligent signal processing technology, inoburitsa zviratidzo zve analog zve4-20mA zvakajairwa, zvichishanda semhinduro yepasi rose yekutarisa tangi uye silo level.
Nhevedzano yeLMUinosanganisira mamodheru manomwe akarongwa zvichienderana nehuwandu hwepamusoro hwekuyera: LMU4, LMU6, LMU8, LMU12, LMU15, LMU20 uye LMU30, ane huwandu hwemvura inoyera hunosvika 4m kusvika 30m. Kune zvinhu zvakasimba, mafungu e ultrasonic anopararira nyore nyore uye anonyudzwa nehupfu, saka huwandu hwemvura inoyera hunosvika 50% chete kana iri mumamiriro ekushanda emvura. Kusarudzwa kwemodheru kunofanirwa kuenderana nenzvimbo yekuisa panzvimbo uye hunhu hwezvinhu. Chigadzirwa chose chinosvika giredhi rekudzivirira re IP67; chifukidziro chayo chekunze chesimbi chine mhepo inodzika uye alkali, zvichibvumira kushanda kwenguva refu pasi pe -40℃ ~ 80℃ uye ± 0.1MPa kumanikidzwa kwakajairika.
2. Nheyo Yekuyera Pakati
Chishandiso ichi chinopedzisa kuyera daro kuburikidza nenzira yekuratidza ruzha panguva yekubhururuka: sensor inoburitsa ma ultrasonic pulses pasi. Mushure mekurova pamusoro pechinhu, mafungu eruzha anodzokera ku probe. Meter inorekodha nguva t pakati pekutumira nekugamuchira, uye inoverenga daro D kubva pa probe kuenda pamusoro pechinhu pamwe chete nekumhanya kweruzha c, ichitevera fomura: D=c·t/2.
Vashandisi vanoisa hurefu hwese hwekuisa H (daro retangi risina chinhu) retangi pachine nguva, uye mita inoshandura yega L=HD panguva chaiyo. Sensor yekupisa yakavakirwa mukati inogadzirisa kutsauka kwekukurumidza kweruzha kunokonzerwa nekuchinja kwekupisa munguva chaiyo kuti ibvise zvikanganiso zvekuyera kubva pakupisa kwemhepo.
Chishandiso ichi chine daro risina chinhu (dead zone B), uko manzwi asingagone kuzivikanwa. Chiyero chose cheF panguva yekuyerwa hachifanirwe kusvika padaro risina chinhu. Daro risina chinhu remodhi yega yega rinowedzera kubva pa0.2m kusvika 1.2m, uye mamodheru ekure anoda nzvimbo yakakura yekuisirwa. Maseti maviri chete emaparameter (kureba kwetangi risina chinhu uye chiyero chakazara) ndiwo anofanirwa kuiswa kuti akwanise kuyerwa nekukurumidza. Mabhatani matatu einduction uye chiratidziro chikuru cheLCD chine manhamba mana chinotsigira kugadzirisa nekugadzirisa zviri nyore panzvimbo.
3. Zvinhu Zvikuru zveChigadzirwa
- Dhizaini yakabatana: Sensor neyuniti yemagetsi zvakabatanidzwa sechinhu chimwe chete, zvine sarudzo dzekuisa screw/flange kuti zvive nyore kubvisa nekuisa pasina waya dzakasiyana.
- Dziviriro yemagetsi akawanda: Mamodule ekudzivirira magetsi akawandisa, magetsi akawandisa uye mheni akavakirwa mukati, achichinjika kumamiriro ezvinhu akaomarara emagetsi mumafekitori.
- Kugona kwakanyanya kudzivirira kukanganiswa: Algorithm yedhijitari ine njere inosefa zvinhu zvinosanganiswa neutsi, guruva, zvinotsigira matangi uye zvinokonzeresa kukanganiswa, zvichiisa mamiriro akaomarara ekushanda kwetangi.
- Kubuda kwechiratidzo kwakajairika: Kubuda kwesimba remagetsi re4-20mA rine mutoro we0~500Ω, rinogona kubatanidzwa zvakananga nePLC, marekodhi nezvimwe zvishandiso zvekudzora zveindasitiri; 4mA inoenderana netangi risina chinhu ukuwo 20mA inoenderana netangi rakazara.
- Kugona kuchinjika pakushanda kwakafara: Imba yemagetsi yesimbi, ABS sensor probe, IP67 inodzivirira guruva, kushanda kwemvura uye kusapinda mvura uye alkali, inoshanda munzvimbo dzakaderera/dzakakwirira uye dzine kumanikidzwa zvishoma.
- Kona yedanda inochinjika: Kona yedanda ye8° (3dB) yemamodheru mapfupi e4/6/8m; Kona yedanda ye5° (3dB) yemamodheru marefu e12~30m, zvichideredza kupindirana kwemanzwi kubva pamadziro etangi uye kuwedzera kugadzikana kwekuyera kure.
4. Maitiro Ekushandisa
Nekubatsira kwekusabata, kushanda pasina kupfeka uye kuenderana nezvinhu zvakasimba nezvinwiwa, LMU series inoshandiswa zvakanyanya mukutarisa nzvimbo dzakasiyana-siyana dzekuchengetera zvinhu mumaindasitiri:
- Indasitiri yemakemikari: Kuongororwa kwemazinga ematangi ekuchengetera acid-base, matangi anodzora tsvina uye matangi e reagent;
- Indasitiri yemagetsi: Matangi emvura anotenderera, matura edota rinobhururuka uye matangi eslurry anobviswa musulfurization;
- Indasitiri yesimbi: Madziva emvura anotonhorera, matura ezvicherwa uye matangi eslurry ane slag;
- Indasitiri yepeturu: Matangi emafuta asina kucheneswa uye madziva etsvina ekuparadzanisa mafuta;
- Kuchengetera zvinhu: Kuyera huwandu hwakasimba hwemasilo ezviyo, mabhini epurasitiki uye mayadhi ejecha.
5.Pfupiso
Nhevedzano yeLMUChinotumirwa ne ultrasonic level chinopa ruzivo rwakabatana newaya mbiri chekuenzanisa mvura uye mazinga akasimba muindasitiri dzemakemikari, simba, simbi uye peturu. Ichitora musimboti wenguva yekubhururuka pamwe nekuripa tembiricha, ine IP67 housing, mheni uye overvoltage dziviriro, 4-20mA output uye 0.2%FS accuracy. Makona akasiyana emwenje anokodzera zviyero zvakasiyana zvekuyera. Isina ngura uye zvinhu zvinonamira, inopa kutarisa kwakaderera kwematangi, madziva nemasilos mumamiriro ekushanda akaoma.
