Gulu la ma gauges a pressure muchowotcha chamafuta chamagetsi chamagetsi, kusankhidwa kwa ma geji okakamiza komanso kukhazikitsa ndi kukonza tsiku ndi tsiku zoyezera kuthamanga.
1 Gulu la zoyezera kuthamanga
Mageji okakamiza amatha kugawidwa m'magulu anayi molingana ndi mfundo zawo zosinthira:
Mtundu woyamba ndi manometer yamadzimadzi:
Malinga ndi mfundo ya hydrostatics, kuthamanga kuyeza kumawonetsedwa ndi kutalika kwa mzere wamadzimadzi. Mawonekedwe ake ndi osiyana, kotero amatha kugawidwa mu mawonekedwe a U-woboola pakati pa chubu choyezera, choyezera champhamvu cha chubu ndi zina zotero. Manometer amtunduwu ali ndi mawonekedwe osavuta komanso osavuta kugwiritsa ntchito, koma kulondola kwake kumakhudzidwa kwambiri ndi zinthu monga machubu a capillary, kachulukidwe ndi parallax. Chifukwa miyeso ndi yopapatiza, nthawi zambiri imagwiritsidwa ntchito kuyeza kutsika kochepa, kusiyana kwa kuthamanga kapena digiri ya vacuum.
Mtundu wachiwiri ndi manometer zotanuka:
Imasinthidwa kukhala kukakamizidwa koyezedwa ndi kusamuka kwa mapindikidwe a zinthu zotanuka, monga kasupe chubu manometer ndi mode manometer ndi kasupe chubu manometer.
Mtundu wachitatu ndi geji yamagetsi:
Ndi chida chomwe chimatembenuza kupanikizika koyezera kukhala kuchuluka kwamagetsi kumakina ndi zida zamagetsi (monga voliyumu, pakali pano, pafupipafupi, ndi zina zotero) poyezera, monga ma transmitters osiyanasiyana ndi ma sensor a pressure.
Mtundu wachinayi ndi piston pressure gauge:
Imayesedwa pogwiritsa ntchito mfundo ya hydraulic press liquid transfer pressure, ndikufanizira kuchuluka kwa silicon code yomwe imawonjezedwa ku pistoni ndi kuthamanga kwake. Ili ndi kulondola kwakukulu, kocheperako ngati 0.05 m'matumbo ~ 0? Kulakwitsa kwa 2%. Koma mtengo wake ndi wokwera mtengo, kapangidwe kake kamakhala kovutirapo. Kuwona mitundu ina ya mawotchi othamanga amapezeka ngati zida zoyezera kuthamanga.
Dongosolo lamafuta otentha limagwiritsidwa ntchito pamagetsi ambiri, lili ndi chinthu chodziwikiratu ndi chubu la bourdon, tebulo mkati mwa kayendedwe ka makina osinthira, kukakamiza kumapangidwa, chubu la Bourdon lidzakhala mapindikidwe zotanuka, kusuntha kwa makinawo. sinthani mapindikidwe otanuka kukhala oyenda mozungulira, ndipo cholozera cholumikizidwa ndi makinawo chimachotsedwa kuti chiwonetse kupanikizika.
Chifukwa chake, choyezera champhamvu chomwe chimagwiritsidwa ntchito mu ng'anjo yamafuta otentha ndi chachiwiri choyezera kuthamanga kwamphamvu.
2 Kusankhidwa kwa kupima kuthamanga
Pamene kupanikizika kwa chowotchera kumakhala kosakwana 2.5 mi, kulondola kwachitsulo choyezera kuthamanga sikucheperachepera 2.5 mlingo: kupanikizika kwa ntchito ya boiler kumaposa 2. SMPa, kulondola kwa kupima kuthamanga sikuchepera 1.5 mlingo. ; Kwa ma boilers omwe ali ndi mphamvu yogwira ntchito kwambiri kuposa 14MPa, kulondola kwa choyezera kuthamanga kuyenera kukhala mlingo 1. Mapangidwe ogwiritsira ntchito makina opangira mafuta otentha ndi 0.7MPa, kotero kulondola kwa magetsi ogwiritsidwa ntchito sikuyenera kukhumudwa 2.5 kalasi 2 Kuchuluka kwa mphamvu yoyezera kuthamanga kuyenera kukhala 1.5 mpaka 3 kuposa kukakamiza kwa boiler, timatenga mtengo wapakati 2 nthawi. Chifukwa chake, pamlingo wa pressure gauge ndi 700.
Kupimidwa kwachitsulo kumayikidwa ku nyumba zowotchera, kuti zikhale zosavuta kuziwona, komanso zosavuta kuchita ntchito zowonongeka nthawi zonse ndikusintha malo a magetsi.
3. Kuyika ndi kukonza tsiku ndi tsiku kwa ng'anjo yamafuta otentha
(l) Kutentha kozungulira kwa choyezera kuthamanga ndi 40 mpaka 70 ° C, ndipo chinyezi sichidutsa 80%. Ngati chiwongola dzanja chikusiyana ndi kutentha komwe kumagwiritsidwa ntchito nthawi zonse, cholakwika chowonjezera cha kutentha chiyenera kuphatikizidwa.
(2) The kuthamanga n'zotsimikizira ayenera ofukula, ndi kuyesetsa kukhalabe mlingo wofanana ndi mfundo muyeso, monga kusiyana ndi mkulu kwambiri mu zolakwika zina chifukwa ndi mzati madzi, muyeso wa gasi sungaganizidwe. Poikapo, lembani kutsegulira kosaphulika kumbuyo kwa mlanduwo kuti zisakhudze ntchito yoteteza kuphulika.
(3) Kuyeza kwazomwe zimagwiritsidwa ntchito kawirikawiri pazitsulo zamagetsi: osapitirira 3/4 ya malire apamwamba pansi pa kupanikizika kosasunthika, ndipo osapitirira 2/3 ya malire apamwamba pansi pa kusinthasintha. Pazigawo ziwiri zomwe zili pamwambazi, muyeso wocheperako wa sikelo yayikulu siyenera kukhala yotsika kuposa 1/3 ya malire otsika, ndipo gawo la vacuum limagwiritsidwa ntchito poyezera vacuum.
(4) Mukamagwiritsa ntchito, ngati cholozera choyezera kuthamanga chikulephera kapena ziwalo zamkati sizigwira ntchito bwino, ziyenera kukonzedwa, kapena kulumikizana ndi wopanga kuti akonze.
(5) Chidacho chiyenera kupewa kugwedezeka ndi kugunda kuti zisawonongeke.
Ngati muli ndi mafunso okhudza ng'anjo yamafuta amagetsi, chondeLumikizanani nafe.
