Momwe mungayang'anire antifreeze ndi refractometer?

Mfundo yogwirira ntchito ndi magulu

Refractometer imagwira ntchito pa mfundo ya refraction: kuwala kwa kuwala kumadutsa kuchokera kumadzi amadzi kupita ku ena, amapindika pamakona osiyanasiyana mpaka pamzere wabwinobwino pakati pa ma mediums awiriwa. Mbali ya refraction imadalira kapangidwe ka sing'anga ndi kutentha. Pamene kuchuluka kwa gulu linalake mu yankho kumawonjezeka, momwemonso kuchuluka kwa kupindika kwa kuwala kwa kuwala. Muyezo wa refraction umatsimikizira zakuthupi zamadzimadzi, makamaka kachulukidwe kake. Zamadzimadzi zomwe zimakhala zonenepa kwambiri kuposa madzi (zimakhala ndi mphamvu yokoka kwambiri) zimakonda kupindika kuwala kudzera mu prism kwambiri kuposa zamadzimadzi zocheperako. Nthawi zambiri, kuyezetsa koteroko kumachitika pansi pazikhalidwe zina zotentha, chifukwa kutentha kumakhudza kwambiri mbali ya refraction.

Pokonza galimoto, ndikofunikira kuyeza kuzizira kwa koziziritsira injini, makamaka ikasakanizidwa ndi madzi. Antifreeze refractometer imathandizira kudziwa mtundu wa choziziritsa. Popeza kuti antifreeze yoyenera imakhalabe mu mawonekedwe amadzimadzi ngakhale nyengo yozizira kwambiri, injini imatetezedwa nthawi zonse.

Refractometers amagawidwa molingana ndi mikhalidwe iwiri:

• Malinga ndi njira yowerengera zotsatira zoyezera. Zida zamitundu ya digito ndi analogi zimapangidwa. Choyamba, chizindikiro chomwe mukufuna chikuwonetsedwa pazenera, chachiwiri, zotsatira za muyeso zimatengedwa pamlingo wa digito. Ma antifreeze refractometers amakhala makamaka amtundu wa analogi: ndi otsika mtengo kwambiri komanso ophatikizika, ndipo kulondola kwapamwamba kwambiri sikofunikira nthawi zambiri.
• Mwa kupangana. Pali mankhwala ndi luso refractometers. Zipangizo zamankhwala ndi zida zapadera, pomwe zaukadaulo zimakhala zapadziko lonse lapansi: muutumiki wamagalimoto, mwachitsanzo, zitha kugwiritsidwa ntchito osati kungozindikira mtundu wa antifreeze, komanso kuwunika kuchuluka kwa electrolyte mu mabatire.

Palinso ma refractometers okhazikika komanso oyenda. Zipangizo zoyima zimafanana ndi maikulosikopu m'mawonekedwe, ndipo zimaperekedwa ndi masikelo. Zotsalazo zimayesedwa kuti ziwerenge mtengo womwe mukufuna, womwe umathandizira kuyeza kwake.

Refractometer chipangizo ndi kukonzekera ntchito

Chipangizochi chili ndi zigawo zotsatirazi:

1. Nyumba zapulasitiki zokhazikika.
2. Refractometer yeniyeni.
3. Kuyeretsa zopukuta.
4. Seti ya machubu oyamwa (nthawi zambiri atatu)
5. Calibrating screwdriver.

Kusinthasintha kwa refractometer kumatsimikiziridwa ndi kuthekera kochita miyeso iyi:

• Kuyeza kutentha kwa malo oziziritsa kutentha kwa antifreeze yamagalimoto kutengera ethylene glycol kapena propylene glycol.
• Kuzindikira mphamvu yokoka ya batri ya asidi ndikupeza chidziwitso chokhudza momwe batire ilili.
• Kuyeza kapangidwe ka ethanol kapena isopropyl alcohol based fluid yomwe imagwiritsidwa ntchito ngati chochapira chotchinga chakutsogolo.

Kuwerenga kwa zisonyezo kumapangidwa pamiyeso, iliyonse yomwe imapangidwira mtundu wina wamadzimadzi. Antifreeze refractometer iyenera kuyesedwa musanagwiritse ntchito koyamba. Pachifukwa ichi, madzi apampopi amagwiritsidwa ntchito, omwe chizindikiro cha sikelo chiyenera kukhala 0.

Momwe mungagwiritsire ntchito optical refractometer?

Mndandanda wa zochita zomwe zimachitika zimatengera mtundu wa refractometer. Mukamagwiritsa ntchito analogi refractometer, chitsanzocho chimayikidwa pa chivundikiro ndi prism, ndiyeno chimayikidwa mu kuwala kuti muwone sikelo, yomwe ili mkati mwa mlanduwo.

Digital refractometers amafuna kuti dontho la yankho la mayeso liyikidwe pachitsime chapadera. Borelo limawunikiridwa ndi gwero la kuwala, nthawi zambiri ndi LED, ndipo chipangizo choyezera chimatanthawuza kutulutsa kwa kuwala kukhala cholozera kapena chilichonse chomwe chida chakonza kuti chiwerenge.

Kuti mupeze zotsatira zake, ndikwanira kuyika 2...4 madontho amadzimadzi ofufuzidwa mu prism kapena pachitsime ndikukonza chivundikirocho - izi zidzawongolera kuyeza kwake, popeza madziwo adzagawidwa mofanana pa prism. Kenako (kwa chida chowunikira) lowetsani gawo la prism la refractometer pagwero la kuwala, ndipo yang'anani diso mpaka sikelo ikuwonekera bwino.

Sikelo imawerengedwa pamalo pomwe madera amdima ndi opepuka amakumana. Kwa digito refractometer, zotsatira zomwe mukufuna zimawonetsedwa pakadutsa masekondi pang'ono pazenera.

Kutentha kwa miyeso ndi 20⁰C, ngakhale chipukuta misozi chodziwikiratu chapangidwira pamitundu 0...30⁰C. Kutalika kwa refractometer sikudutsa 160 ... 200 mm. Iyenera kukhala yowuma komanso yaukhondo.

Antifreeze refractometer ndiyoyenera kudziwa kuchuluka kwa mafuta opaka ngati ma refractive index awo ali mkati mwaukadaulo wa chipangizochi. Kuti muchite izi, chithunzi cha Brix chimakonzedwa koyambirira ndipo zomwe mwapeza zimasinthidwa kukhala chizindikiro cha kuchuluka kwa sing'anga yoyezera.
