Mhando dzeMapaipi Anoyerwa neElectromagnetic Flowmeters

1. Machira erabha

1.1 Rabha Yechisikigo

Rabha yechisikigo isarudzo yakakurumbira yekuisa mapaipi mumashandisirwo ayo nzvimbo yakayerwa isingakanganisi uye ine tembiricha yakaderera. Inopa simba rakanaka rekudzivirira kukwesha, izvo zvinoita kuti ikwanise kushandisa mvura inogona kunge iine zvidimbu zvakasungirirwa, senge mamwe marudzi emvura yakasviba kana matope ane zvinhu zvakapfava. Semuenzaniso, mufekitori yekuchenesa tsvina, maitiro ekurapa ane simba uye ekutanga anowanzo sanganisira kuyerera kwemvura yakasviba ine marara akasiyana-siyana. Mapaipi erabha echisikigo anogona kutsungirira kukweshana kunokonzerwa nezvidimbu izvi uku achienderana nechiyereso chemagetsi chinoyerera.Rutivi rwerabha rwechisikigo runopa nzvimbo yemukati yakatsetseka, zvichideredza kuramba kwemvura uye zvichiita kuti kuyerwa kwemvura kwakarurama ne electromagnetic flowmeter.

1.2 Rabha rekugadzira (semuenzaniso, Neoprene)

Marabha ekugadzira akadai se neoprene ane simba rekudzivirira makemikari zvakanyanya kana tichienzanisa nerabha yechisikigo. Mapaipi ane neoprene akakodzera kuyera mvura inoparadza zvishoma, senge mamwe maasidhi asina simba kana alkali mukati mehuwandu hwakatarwa. Mumabasa emaindasitiri uko kune mishonga yekuchenesa makemikari iri kutakurwa mumapaipi, mapaipi ane neoprene anogona kushandiswa pamwe chetema electromagnetic flowmeters.Rutivi rwe neoprene harungodziviriri chete pombi kubva mukurwiswa nemakemikari asiwo runochengetedza simba remagetsi rinoshandiswa pakuyera kuyerera, zvichiita kuti pave neruzivo rwakarurama rwekuyerera kwemvura yemakemikari aya.

2. Mapeteni eFluoropolymer

2.1 PTFE (Polytetrafluoroethylene)

PTFE inozivikanwa nekusagona kwayo makemikari, ichikwanisa kutsungirira mhando dzakasiyana-siyana dzemakemikari anoparadza zvakanyanya, kusanganisira maasidhi akasimba, mabhesi, uye ma oxidizing agents. Mapaipi ane PTFE anowanzo shandiswa muindasitiri yemakemikari, kugadzira mishonga, uye kugadzira semiconductor. Mufekitori yemakemikari umo makemikari anotsausa akadai se sulfuric acid yakawanda kana hydrofluoric acid ari kutamiswa, electromagnetic flowmeter inogona kuiswa papaipi ine PTFE. Iyo PTFE lining inoita kuti paipi isakuvadzwe ne corrosive medium, uye hunhu hwayo husingafambi uye hwakagadzikana hwemakemikari hahupindire musimboti wekuyera electromagnetic. Izvi zvinobvumira kuyerwa kwekuyerera kwakanyatsojeka kunyangwe munzvimbo dzakaoma dzemakemikari.

2.2 FEP (Fluorinated Ethylene Propylene)

FEP chimwe chinhu che fluoropolymer lining. Ine makemikari akafanana nePTFE asi ine zvimwe zvakanakira maererano nekugona kwayo kugadzikiswa uye kujeka. Mapaipi ane FEP anowanzo shandiswa mukushandiswa uko kuongorora kwemvura kunodiwa pamwe nekuyera kuyerera kwayo kwakarurama. Semuenzaniso, mune mamwe maitiro emakemikari emurabhoritari kana mukugadzirwa kwemvura yakachena muindasitiri yemishonga, mapaipi ane FEP anogona kusanganiswa nemagetsi emagetsiKujeka kweFEP kunoita kuti vashandisi vakwanise kuona mamiriro ekuyerera kwemvura, ukuwo electromagnetic flowmeter ichipa data rechokwadi rehuwandu hwekuyerera kwemvura.

3. Matanda eCeramic

Mapaipi ane jira reCeramic akakodzera zvikuru kushandiswa kunoda kudzivirira kupisa kwakanyanya uye kudzivirira kupfeka kwakanaka. Mapaipi ane jira reCeramic anonyunguduka zvakanyanya uye anogona kuchengetedza hunhu hwawo hwemakanika nemakemikari pakupisa kwakakwira. Mumaindasitiri akadai sekugadzira magetsi, uko kune magasi anopisa ane magasi kana matope ekupisa kwakanyanya, mapaipi ane jira reCeramic anogona kushandiswa nema electromagnetic flowmeters. Ceramic lining inodzivirira paipi kubva pakukukurwa kwezvikamu zve high-speed mu fluid, uye electromagnetic flowmeter inogona kuyera nemazvo mwero wekuyerera kweaya ma fluids ane tembiricha yakakwirira. Kunyangwe ma ceramic ari zvinhu zvisina kusimba, kuiswa kwakakodzera uye dhizaini ye system yemapaipi kunogona kuve nechokwadi chekuti inoshanda kwenguva refu pamwe chete nema electromagnetic flowmeters.

Mukupedzisa,magetsi emagetsiinogona kushandiswa zvinobudirira nemapaipi akafukidzwa nerabha (zvese zvakasikwa uye zvekugadzira), fluoropolymers (PTFE neFEP), uye ceramics. Kusarudzwa kwezvinhu zvemukati zvinoenderana nehunhu hwechinhu chakayerwa, senge kuumbwa kwemakemikari, tembiricha, uye kusakara, kuve nechokwadi chekuyera kuyerera kwakarurama uye kwakavimbika.
