Zotumizira mafuta mkati mwa mzerendi zida zofunika kwambiri poyesa kuthamanga kwa mafuta mkati mwa payipi kapena makina, zomwe zimapereka kuwunika ndi kuwongolera kuthamanga kwa mafuta nthawi yeniyeni. Poyerekeza ndi ma transmitter wamba, mitundu yamkati imapangidwa kuti iphatikizidwe bwino munjira yoyenda kudzera mu kulumikizana kwa ulusi kapena kolumikizana, komwe ndi koyenera kwambiri pamafuta ndi gasi, magalimoto, makina amadzimadzi ndi makina amafakitale.
Dziwani zofunikira pakugwiritsa ntchito musanasankhe ma transmitter amafuta othamanga. Kuwerengera kwa kuthamanga komwe kumayesedwa kumasinthidwa kukhala zizindikiro zamagetsi ndikuperekedwa ku dongosolo lowongolera lanzeru kuti liwunikidwenso ndikuwongolera kwina.
Zinthu Zofunika Kwambiri Zofunika Kuziganizira Mosamala
Kuchuluka kwa kuthamanga kwa mpweya, kuyenda kwa mpweya ndi kukhuthala kwa mpweya, ukadaulo wosiyanasiyana wozindikira, zinthu zogwirizana ndi chizindikiro chotuluka ziyenera kuganiziridwa kuti ziwunikire molondola komanso modalirika. Nthawi yomweyo, zofunikira pa chilengedwe ndi chitetezo ziyenera kuyesedwa kuti zigwirizane ndi zomwe zikuchitika m'madera omwe mukufuna.
Zofunikira pa Kugwiritsa Ntchito Mtengo
Kupanikizika kwa mafuta pang'ono ndi kwakukulu mu mapaipi kumatsimikizira kutimitundu yosiyanasiyana ya ma transmitter opanikizikaimaphimba mfundo izi kuti ipewe kuwonongeka kapena kuwerengedwa kolakwika.
Mitundu ya kuyeza kuthamangaZigawidwa m'magulu a kupanikizika koyezera, kupanikizika kwathunthu ndi kupsinjika kosiyana, zomwe zimagwirizana ndi kupsinjika kwa mlengalenga, vacuum kapena kusiyana pakati pa mfundo ziwiri molingana.
Ma diaphragm otsukira amafunikawokhuthala kapena wosokonezekakuyenda chifukwa choopa kutsekeka kapena zolakwika muyeso.
Ukadaulo Wozindikira wa Zotumiza Mphamvu
Zotumiza zamagetsindi oyenera kugwiritsidwa ntchito pazinthu zonse, momwe njira zotumizira mphamvu zamagetsi zotsika mtengo komanso zolondola pang'ono zimafunikira;
Zotumiza za silicon zofalikiraamagwiritsidwa ntchito pamakina a hydraulic kapena mafuta ndi gasi kuti azitha kulondola kwambiri komanso kukhazikika pamakina opanikizika kwambiri;
Zipangizo Zogwirizana
Sankhani Chizindikiro Choyenera Chotulutsa
Chotulutsa cha transmitter chiyenera kugwirizana ndi makina anu owongolera kapena owunikira:
- 4-20 mA: Muyezo wa ntchito zamafakitale, wodalirika potumiza chizindikiro cha mtunda wautali.
- 0-10 V: Yoyenera makina ogwiritsira ntchito magetsi, omwe nthawi zambiri amagwiritsidwa ntchito m'magalimoto kapena m'makonzedwe ang'onoang'ono.
- Zotulutsa za digito (monga, HART, Modbus): Imakonda kwambiri machitidwe anzeru omwe amafunikira matenda kapena kusinthidwa kwakutali.
Tsimikizani kuti chizindikiro chotuluka chikugwirizana ndi zofunikira za makina anu kuti muwonetsetse kuti kulumikizana kwake kuli bwino.
Unikani Zofunikira pa Zachilengedwe ndi Chitetezo
Ma transmitter olowera mkati nthawi zambiri amakhala ndi zovuta:
- Malo Oopsa: Mu mafuta ndi gasi (monga mapaipi, mafakitale oyeretsera), sankhani ma transmitter osaphulika kapena otetezeka omwe ali ndi ziphaso zovomerezeka ndi miyezo monga ATEX, FM, kapena CSA kuti mupewe zoopsa zoyatsira moto.
- Chitetezo cha Kulowa (IP/NEMA Ratings): Pa malo akunja kapena onyowa, sankhani chotumizira chomwe chili ndi IP rating yapamwamba (monga, IP67 kapena IP68) kuti chiteteze ku fumbi, madzi, kapena mafuta kulowa.
- Kuchuluka kwa Kutentha: Onetsetsani kuti chotumiziracho chikugwira ntchito molingana ndi malire a kutentha kwa makina anu. Ma transmitter omwe ali mkati mwa makina omwe amagwiritsidwa ntchito kutentha kwambiri (monga kuyang'anira mafuta a injini) amafunika kupirira kutentha kwambiri.
Sankhani Njira Yoyenera Yolumikizira
Ma transmitter olowera mkati ayenera kulumikizidwa bwino ku payipi:
- Maulalo Olumikizidwa: Zosankha zodziwika bwino monga ulusi wa 1/4” NPT, G1/2, kapena M20 ndizoyenera kugwiritsa ntchito zambiri mkati mwa mzere. Onetsetsani kuti mwatseka bwino (monga mphete za O kapena tepi ya PTFE) kuti mupewe kutuluka kwa madzi.
- Maulumikizidwe Ozungulira: Amagwiritsidwa ntchito m'mapaipi okhala ndi mphamvu yamagetsi kapena ya m'mimba mwake yayikulu kuti achepetse mphamvu yamagetsi komanso kuti akhazikike bwino.
- Kugwirizana kwa Kukula kwa Chitoliro: Onetsetsani kuti kulumikizana kwa transmitter kukugwirizana ndi kukula kwa chitoliro chanu kuti mupewe zoletsa kuyenda kwa madzi kapena mavuto okhazikitsa.
Sankhani mtundu wolumikizira womwe umatsimikizira kuti kukhazikitsa kwake kuli kolimba komanso kosataya madzi popanda kusokoneza kayendedwe ka madzi.
Mtengo Wokwanira ndi Magwiridwe Abwino
Ngakhale zipangizo zapamwamba monga tantalum kapena ukadaulo wapamwamba zimathandizira kulimba ndi kulondola, sizingakhale zofunikira pakugwiritsa ntchito kosavuta. Ma transmitter ochokera ku SS316L okhala ndi ukadaulo wa capacitive kapena piezoresistive nthawi zambiri amapereka ndalama zotsika mtengo. Ganizirani ndalama zomwe zimagwiritsidwa ntchito nthawi zonse, kuphatikizapo kukonza, kuwerengera, ndi nthawi yomwe ingagwire ntchito, poyesa njira zina. Transmitter yodalirika imachepetsa ndalama zomwe zimagwiritsidwa ntchito nthawi yayitali.
