Choyezera cha ultrasonic chomwe sichingaphulike

Posankha mita yoyezera ya ultrasonic yolimbanira ndi kuphulika, zinthu zotsatirazi ziyenera kuganiziridwa. Choyamba ndi mulingo woyezera, mulingo woyezera wa chipangizocho ndi mamita 0-15, womwe ndi woyenera kuyeza mulingo wosiyanasiyana wamadzimadzi a m'chidebe. Chachiwiri ndi mita yoyezera ya ultrasonic yolimbanira ndi kutentha kwa malo ozungulira, yomwe singaphulike, imatha kugwira ntchito bwino m'malo ovuta kuyambira -40 ° C mpaka +60 ° C kuti zitsimikizire kudalirika ndi kukhazikika kwa chipangizocho. Mulingo woteteza nawonso ndi wofunika kuganizira, ndipo chipangizocho chikugwirizana ndi kalasi yolimbanira ndi kuphulika ya ExdIICT6, yomwe ndi yoyenera kuzindikira mulingo wamadzimadzi m'malo omwe amatha kuyaka komanso kuphulika. Kuphatikiza apo, chizindikiro chotulutsa ndi chinthu china chomwe chimafunikira chisamaliro. Mita yolimbanira ndi kuphulika imapereka njira ziwiri zotulutsira za chizindikiro cha analog cha 4-20mA ndi chizindikiro cha digito cha RS485, chomwe ndi chosavuta kuwongolera kulumikizana ndi zida zina. Ponena za mawonekedwe osinthira, chipangizocho chimagwiritsa ntchito njira yosinthira ya njira ziwiri kuti chikwaniritse kutumiza zizindikiro zoyezera mbali zonse ziwiri ndikuzizindikira mobwerezabwereza kuti zitsimikizire kulondola ndi kudalirika kwa muyeso. Zofunikira pakuwunika bwino ndi chimodzi mwazinthu zomwe ziyenera kuganiziridwa posankha, mita yoyesera ya ultrasonic yomwe singathe kuphulika ili ndi mphamvu yoyezera bwino kwambiri, yolondola ya ± 0.5%, kuti ikwaniritse zosowa zolondola pakupanga. Pomaliza, njira yoyikira, zida zimapereka njira zoyikira mbali, zoyikira pamwamba ndi njira zoyikira zamtundu wa flange, mutha kusankha njira yoyenera yoyikira malinga ndi momwe zinthu zilili.

Kuwonjezera pa zinthu zosankhira, magawo aukadaulo a mita yoyezera ultrasonic yomwe singathe kuphulika ayeneranso kumvedwa. Mphamvu yamagetsi yogwiritsira ntchito chipangizocho ikhoza kusankhidwa kukhala AC220V kapena DC24V, nthawi yogwiritsira ntchito ndi 20-100kHz, nthawi yoyankhira ndi masekondi 1.5, ndipo nthawi yochedwetsa chizindikiro ndi masekondi 2.5. Ponena za njira zolumikizirana, thandizirani njira za Modbus ndi Hart. Zida zolumikizirana zomwe zingagwiritsidwe ntchito zimaphatikizapo madzi ndi olimba. Cholakwika cha dongosolo ndi ±0.2%, ndipo mphamvu yoletsa kusokoneza imafika 80dB.

Choyezera kuchuluka kwa madzi chomwe sichingaphulike chimagwiritsidwa ntchito kwambiri mu mankhwala, petrochemical, metallurgy, magetsi, kuyeretsa madzi ndi zina. Chingagwiritsidwe ntchito pozindikira kuchuluka kwa madzi m'matanki osungiramo zinthu, ma reactor, mapaipi, matanki osungiramo zinthu ndi ma transformer. Mu makampani opanga mankhwala, chimatha kuonetsetsa kuti madzi osiyanasiyana akusungidwa bwino komanso kunyamulidwa bwino; Mu makampani opanga zitsulo, chimatha kuyang'anira kuchuluka kwa madzi m'zinthu zamagetsi ndi mafuta; Mu makampani opanga magetsi, chingagwiritsidwe ntchito powunikira kuchuluka kwa madzi m'ma transformer; Mu makampani opanga madzi, chingagwiritsidwe ntchito poyeretsa madzi akumwa ndi kuyang'anira kuchuluka kwa madzi omwe akuchokera. Kuphatikiza apo, chimagwiritsidwanso ntchito powunikira kuchuluka kwa madzi m'mafakitale ena.
