Buku Lothandizira Kukhazikitsa kwa UOC Series Open Channel Flowmeter

Bukuli likufotokoza njira zofunika kwambiri zokhazikitsira chipangizo cholandirira ndi chofufuzira, zomwe zikuphatikizapo zinthu zokhudzana ndi chilengedwe, kuyika makina, ndi makonzedwe apadera a ntchito. Magawo otsatirawa amapereka malangizo atsatanetsatane kuti atsimikizire kulondola kwa muyeso komanso kukhazikika kwa dongosolo kwa nthawi yayitali.

I. Malangizo a kukhazikitsa kwa wolandila l

•Chosungiracho sichiyenera kuyikidwa pamalo otsekedwa pomwe kutentha kumatha kupitirira kutentha kwabwinobwino kogwira ntchito (-40~+75), ngati chosungiracho chayikidwa panja, chiyenera kutetezedwa ku dzuwa lachindunji kapena nyengo yoipa.

•Onetsetsani kuti malo okwererapo sakugwedezeka ndipo sali pafupi

ku zingwe zamagetsi amphamvu kwambiri, ma contactor kapena zowongolera zamagalimoto.

•Sankhani ma knockout oyenera pansi pa chitsekocho ndikuyika ma cable glands oyenera kuti musunge IP67.

•Musagwiritse ntchito mphamvu zambiri mukamangirira chomangiracho ndipo pewani kupotoza kulikonse kwa chomangiracho. •Samalirani kukula kwa chomangiracho ndi chomangiracho.

IIMalangizo okhazikitsa probel

•Chofufuzirachi chingaperekedwe ngati muyezo kapena ndi screw nati kapena ndi flange yolamulidwa.

•Onetsetsani kuti choyezeracho chayikidwa molunjika pamalo owunikidwa ndipo ndibwino kuti chikhale pamtunda wa mamita 0.25 pamwamba pake, chifukwa choyezeracho sichingalandire yankho m'dera losawoneka.

•Chofufuzirachi chili ndi mngelo wa conical beam 10 womwe uli ndi mphamvu ya 3 dB ndipo chiyenera kuyikidwa ndi madzi owoneka bwino kuti ayezedwe. Koma thanki yosalala ya makoma olunjika a m'mbali sidzayambitsa zizindikiro zabodza.

•Kwamita yoyendera njira yotseguka ya flumekukhazikitsa, ikani chofufuziracho pamwamba pa kapangidwe ka muyeso.

•Musamange kwambiri mabotolo a pa flange. l

•Mukayika pamalo ozizira, muyenera kusankha sensa yotalikitsa ndikupangitsa sensayo kuti ikule mu chidebe, pewani chisanu ndi icing.
