Mu ntchito zamakina ndi zida zamafakitale, mafuta a hydraulic ndi mafuta opaka mafuta amagwira ntchito yofunika kwambiri ngati "magazi a moyo" - kuonetsetsa kuti mphamvu zimafalikira bwino, kuchepetsa kukangana pakati pa ziwalo zoyenda, ndikuwonjezera moyo wa ntchito ya zida zamakanika. Kuyeza molondola kuchuluka kwa kayendedwe ka madzi sikungoyang'anira ntchito koma ndi maziko osamalira zida, kugwiritsa ntchito mphamvu moyenera, komanso kuwongolera ndalama. Pakati pa ukadaulo wosiyanasiyana woyezera kayendedwe ka madzi womwe ulipo, mita yoyezera kayendedwe ka madzi yakhala njira yabwino kwambiri yogwiritsira ntchito mafuta a hydraulic ndi mafuta opaka mafuta, chifukwa cha kulondola kwawo kwapadera, kulimba, komanso kusinthasintha kuzinthu zapadera zamadzimadzi awa.
Ma gear flow meter ali m'gulu la positive displacement flow meter, omwe amagwira ntchito motsatira mfundo yosavuta koma yothandiza kwambiri. Mkati mwa nyumba ya meter, ma gear awiri kapena angapo olumikizana amazungulira pamene madzi akudutsa m'chipindamo. Kuzungulira kulikonse kwa ma gear kumachotsa voliyumu yokhazikika ya madzi, ndipo kuchuluka kwa ma rotations—omwe amalembedwa kudzera mu masensa (makina kapena zamagetsi)—kumasinthidwa kukhala kuwerenga kolondola kwa flow rate. Njira yabwino yosinthira iyi imapereka ubwino wofunikira wa mafuta a hydraulic ndi mafuta opaka, omwe nthawi zambiri amawonetsa kukhuthala kwakukulu, kutentha kosiyanasiyana, komanso amakhala ndi zodetsa zazing'ono. Mosiyana ndi ma flow meter otengera liwiro (monga turbine kapena ultrasonic mita), ma gear flow meter sakhudzidwa kwambiri ndi kusintha kwa kukhuthala kwa madzi, kuonetsetsa kuti kulondola kokhazikika ngakhale akamagwiritsa ntchito madzi kuyambira otsika mpaka okwera kwambiri omwe amagwiritsidwa ntchito kwambiri m'makina a hydraulic ndi ma circuits opaka.
Chimodzi mwa zifukwa zazikulu zomwe ma gear flow meter amagwirira ntchito bwino mu hydraulic oil ndi mafuta opaka ndi kuthekera kwawo kuthana ndi zovuta za m'mafakitale. Makina a hydraulic nthawi zambiri amagwira ntchito pamavuto akulu (nthawi zambiri opitilira 300 bar) ndi kutentha, pomwe mafuta opaka amatha kuyenda kudzera m'mapaipi olimba komanso m'mabwalo ovuta. Ma gear flow meter a mafakitale amapangidwa ndi zinthu zolimba monga chitsulo chosapanga dzimbiri, zitsulo zolimba za alloy, kapena ma polima osagwira dzimbiri, kuonetsetsa kuti amatha kupirira kuthamanga kwambiri, kusinthasintha kwa kutentha, komanso mtundu wa mafuta ena opaka. Kulekerera kolimba popanga ma gear kumachepetsa kutayikira kwamkati, kupititsa patsogolo kulondola kwa muyeso - ndikofunikira kwambiri pamagwiritsidwe ntchito pomwe ngakhale kusintha pang'ono kwa kuthamanga kwa madzi kungayambitse kusagwira bwino ntchito kwa zida kapena kuwonongeka msanga. Mwachitsanzo, mumakina omanga (monga ma excavator ndi ma crane), muyeso wolondola wa mafuta opaka ndi madzi kumathandiza kukonza kugawa kwa mphamvu, kupewa kudzaza kwambiri kwa ma hydraulic pumps ndikuchepetsa kugwiritsa ntchito mafuta. Mu malo opangira zinthu, deta yolondola yokhudza kuyenda kwa madzi opaka mafuta imatsimikizira kuti ma bearing, magiya, ndi zinthu zina zofunika kwambiri zimalandira kuchuluka koyenera kwa mafuta opaka mafuta, kupewa mafuta osakwanira (omwe amachititsa kukangana ndi kutentha kwambiri) komanso mafuta opaka mafuta mopitirira muyeso (omwe amawononga madzi ndikuwonjezera ndalama zokonzera).
Ubwino wina wa ma gear flow meter ndi wogwirizana ndi mawonekedwe apadera a mafuta a hydraulic ndi mafuta odzola. Madzi awa nthawi zambiri amakhala ndi zowonjezera (monga zoletsa kusweka, zoletsa dzimbiri, ndi zowongolera kuchuluka kwa viscosity index) zomwe zingakhudze magwiridwe antchito a zida zina zoyezera kuyenda. Komabe, ma gear flow meter sagwirizana kwambiri ndi chemistry yamadzimadzi—mfundo yawo yoyezera imadalira kusuntha kwa makina m'malo mwa zinthu zamadzimadzi monga conductivity kapena acoustic impedance. Izi zimawapangitsa kukhala oyenera mitundu yosiyanasiyana ya mafuta a hydraulic (kuphatikiza mafuta amchere, opangidwa, ndi owonongeka) ndi mafuta odzola (monga mafuta a mota, mafuta a gear, ndi mafuta). Kuphatikiza apo, ma gear flow meter amatha kugwira ntchito bwino ndi madzi okhala ndi tinthu tating'onoting'ono (monga, zodulidwa zazing'ono zachitsulo kapena fumbi), bola ngati tinthu tating'onoting'ono sitikwanira kudzaza ma gear—zomwe zimachitika kawirikawiri m'mafakitale komwe kuipitsidwa kwa madzi nthawi zina sikungapeweke.
Ponena za kukhazikitsa ndi kugwiritsa ntchito bwino, ma gear flow meter amapereka kusinthasintha kwakukulu, zomwe zimapangitsa kuti zikhale zosavuta kuziphatikiza mu ma hydraulic ndi ma lubrication system omwe alipo. Amatha kuyikidwa m'mapaipi opingasa kapena oimirira, ndi zofunikira zochepa za mapaipi owongoka—mosiyana ndi ma flow meter ena omwe amafunikira ma flow meter ataliatali kuti atsimikizire kuti ma flow meter ndi olondola. Kapangidwe kakang'ono aka ndi kothandiza kwambiri m'makina amafakitale komwe malo ndi ochepa. Ma gear flow meter amakono amabweranso ndi mitundu yosiyanasiyana ya zotuluka, kuphatikiza ma analog signals (4-20 mA), ma digital signals (RS485, Modbus), ndi ma pulse outputs, zomwe zimathandiza kuphatikizana bwino ndi ma control system, deta loggers, ndi mapulogalamu owunikira. Izi zimathandiza kutsata flow rate nthawi yeniyeni, kuyang'anira kutali, ndi machenjezo odziyimira pawokha a zinthu zosazolowereka—monga flow flow yochepa (yosonyeza kuti pakhoza kutayikira kapena kutsekeka) kapena flow flow yambiri (yomwe ikusonyeza kuti system disable). Kwa magulu okonza, deta iyi ndi yofunika kwambiri: imalola kuthetsa mavuto mwachangu, imachepetsa nthawi yogwira ntchito, ndikuwonjezera moyo wa flow meter ndi zida zomwe imayang'anira.
Posankha choyezera kuyenda kwa giya cha mafuta a hydraulic ndi mafuta opaka, zinthu zingapo zofunika kuziganizira kuti zitsimikizire kuti zikugwira ntchito bwino. Choyamba, kuchuluka kwa kuyenda kwa mita kuyenera kufanana ndi zomwe zimagwiritsidwa ntchito - kuchuluka kochepa kwambiri kungayambitse kupitirira muyeso, pomwe kuchuluka kwakukulu kwambiri kudzasokoneza kulondola. Chachiwiri, kupanikizika ndi kutentha kuyenera kupitirira mikhalidwe yayikulu yogwirira ntchito ya dongosololi kuti zisawonongeke. Chachitatu, kugwirizana kwa zinthu ndikofunikira kwambiri: pamadzimadzi owononga kapena malo ovuta, mamita opangidwa ndi chitsulo chosapanga dzimbiri kapena alloys apadera amalimbikitsidwa. Chachinayi, mtundu wa sensa (yamakina kapena yamagetsi) uyenera kusankhidwa kutengera kufunikira kolondola, kutulutsa deta, ndi zofunikira pakukonza - masensa amagetsi amapereka kulondola kwakukulu komanso kuphatikiza kwa digito, pomwe masensa amakina nthawi zambiri amakhala otsika mtengo ndipo amafuna kukonza kochepa. Pomaliza, kuchuluka kwa ma calibration kuyenera kuganiziridwa: kuwerengera nthawi zonse (nthawi zambiri pachaka) kumatsimikizira kuti mita imasunga kulondola kwake pakapita nthawi, makamaka pakugwiritsa ntchito kwambiri.
Pomaliza, mita yoyezera kuyenda kwa magiya ndi njira yabwino kwambiri yoyezera mafuta a hydraulic ndi mafuta odzola m'malo opangira mafakitale. Kapangidwe kake kabwino ka kusuntha kamapereka kulondola kopanda malire, ngakhale ndi madzi okhuthala kwambiri komanso mikhalidwe yosiyanasiyana yogwirira ntchito. Kapangidwe kawo kolimba kamatsimikizira kulimba ndi kudalirika m'malo ovuta amakampani, pomwe kugwirizana kwawo ndi mitundu yosiyanasiyana yamadzimadzi ndi kuyika kosavuta kumapangitsa kuti zikhale zosinthika komanso zosavuta kugwiritsa ntchito. Mwa kupereka deta yolondola komanso yeniyeni ya kuchuluka kwa madzi, mita yoyezera kuyenda kwa magiya imathandiza mabizinesi kukonza magwiridwe antchito a zida, kuchepetsa ndalama zokonzera, kukonza mphamvu moyenera, ndikupewa nthawi yotsika mtengo yogwira ntchito. Kwa mafakitale kuyambira opanga ndi zomangamanga mpaka magalimoto ndi ndege, kuyika ndalama mu mita yoyezera kuyenda kwa magiya abwino kwambiri si nkhani yongoyerekeza - ndi chisankho chanzeru chomwe chimawonjezera magwiridwe antchito ndi mpikisano m'malo ovuta amakampani masiku ano. Pamene ukadaulo ukupita patsogolo, mita yoyezera kuyenda kwa magiya ikupitilizabe kusintha, ndi zipangizo zabwino, masensa anzeru, komanso kulumikizana bwino, zomwe zimalimbitsa malo awo ngati chisankho chotsogola cha mafuta a hydraulic ndi mafuta odzola.
