Popanga ndi magetsi, ma valve ambiri a pachipata, ma valve a disc ndi ma hydraulic butterfly valve amagwiritsidwa ntchito popanga mabizinesi, makamaka m'mizinda ikuluikulu. Amayang'anira kupanga ndi kupanga madzi akumwa, omwe ndi zida zazikulu zamakampani opanga magetsi. Valve yachipata chamagetsi imakhala ndi valavu yowongolera magetsi ndi zida zothandizira valavu. Amagwiritsidwa ntchito potsegula ndi kutseka kwa valve yachipata. Itha kugwiritsidwa ntchito pomwepo ndipo imatha kuyendetsedwa patali.
Mabizinesi opanga, makamaka makampani operekera madzi m'mizinda ikuluikulu, amagwiritsa ntchito mavavu ambiri pachipata, mavavu a chimbale, ma hydraulic butterfly mavavu, ndi zina zambiri, popanga ndi magetsi, kuti adziwe kupanga ndi kupanga madzi akumwa, omwe ndi zida zofunika kwambiri zamakampani opanga magetsi. Pali ma valve ambiri a zipata omwe amagwiritsidwa ntchito pamitundu yonse ya ma valve a zipata. Zimasonkhanitsidwa ndi netiweki yamagetsi yapampu yaku China ndipo ikuphunzitsani kusintha chipangizo chamagetsi chamagetsi owongolera pamanja.
Valve yachipata chamagetsi imakhala ndi valavu yowongolera magetsi ndi zida zothandizira valavu. Amagwiritsidwa ntchito potsegula ndi kutseka kwa valve yachipata. Itha kugwiritsidwa ntchito pomwepo ndipo imatha kuyendetsedwa patali. Valavu yoyang'anira magetsi imakhala ndi mota, chochepetsera, makina ochepetsa ma torque, makina owongolera ma stroke, makina osinthira magetsi amtundu wamanja, makina otsegulira ma degree ndi gulu lowongolera zida zamagetsi. Ngati kusintha kwa chipangizo chamagetsi cha valve yachipata chamagetsi sikuli koyenera, moyo wautumiki wa valve valve uyenera kuchepetsedwa. Ngozi zazikulu monga chitseko cha valve pig iron casing breaking control motor burning and setting pump room. Choncho, pofuna kuonetsetsa kuti magetsi otetezeka komanso osasunthika, m'pofunika kusintha chipangizo chamagetsi cha valve yamagetsi kuti muwonetsetse kuti kutsegula bwino ndi kutseka kwa valve yamagetsi. Tsatanetsatane wa njira ziwiri zosinthira za valve yamagetsi pachipata:
1. Kusintha kwa makina ochepetsa ma torque
Ma valve a zipata zamagetsi amagwiritsidwa ntchito m'malo osiyanasiyana chifukwa cha kusiyana kwa kuthamanga kumapeto kwa valve yachipata kapena kusiyana kwa mpweya (valavu yachipata yotsekedwa), njira yochepetsera torque iyenera kusinthidwa moyenera. Pogwiritsa ntchito valavu yamagetsi yamagetsi kumbali zonse ziwiri za kuthamanga kwa azimuthal kapena kutsika kwa mpweya, njira yochepetsera torque iyenera kusinthidwa kukhala torque yotsika, zinthu zamtundu wa HZ (monga momwe zikuwonetsera Chithunzi 1), Z mndandanda wazinthu (monga momwe tawonetsera pachithunzichi). 2) kapena zinthu zotsatizana za ZB (monga momwe zasonyezedwera pa Chithunzi 3) valavu yoyendetsera magetsi, imangofunika kusintha mbale yosinthira ma torque ndi mtunda pakati pa mbale yosuntha kuti mukwaniritse (kusintha mwatsatanetsatane). Pulati yolamulira imakhala ndi cholembera, ndipo kuchuluka kwa sikelo kumachulukirachulukira mtengo wa torque. Vavu yoyang'anira chipata cha valavu yamagetsi imatsekedwa pamene kusiyana kwapakati pakati pa malekezero awiri kapena kupanikizika kwa mpweya kumawonjezeka, mtengo wosinthika wa torque uyenera kukhala wochuluka, m'malo mwake, wochepa. Pamwambapa angapo mndandanda wa mankhwala kusintha njira ndi chimodzimodzi. Mukakonza valavu yoyendetsera magetsi ya ZD (monga momwe tawonetsera pa Chithunzi 4), chotsani chivundikiro cham'mbali cha chipolopolo, sinthani makina ochepetsera ma torque, masulani zomangira zomangira, masulani zomangira, masulani batani lokakamiza, masulani kasupe wa torque, ndi kuika mu gawo lotayirira, ndi kumangitsa zomangira zomangira mu zomangira zosinthira, konzani zomangira zosinthira. Zindikirani kuti pamwamba pa zomangira zokonzera ziyenera kugwera mu thupi la shaft groove. Ngati pamwamba sikuloza ku tsinde la shaft ndendende, kungozungulira pang'ono kwa wononga kolowera komwe kumachokera kasupe wa torsion ndikofunikira kuti iloze ku phula lopangira shaft. Valani pachivundikiro cham'mbali ndikusintha valve yachipata. Ngati torque limit mechanism imachita masewera olimbitsa thupi, kasupe wa torsion ndi womasuka kwambiri komanso wothina pamalopo. Izi zitha kupangitsa kuti makina ochepetsera ma torque agwire ntchito pansi pa torque yotsika, kuwonetsetsa kuti valavu yamagetsi yamagetsi chifukwa cha kulephera kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake valavu sichidzawonongeka. Valve yamagetsi yamagetsi yomwe imagwiritsidwa ntchito m'malo ena sichiyeneranso kusinthidwa kuti itseke kwambiri, kusinthidwa ku mtundu wamanja wapafupi ndikumasula mphete ziwiri (kapena mphete) ndiyoyenera, (kapena palibe madzi kapena mpweya woyenera) .
Pamene valavu yamagetsi yamagetsi imayikidwa pamalo omwe kusiyana kwa madzi kumatulutsa (kapena kuthamanga kwa mpweya) kumakhala kochuluka, njira yochepetsera torque iyenera kusinthidwa kuti ikhale yoyenera kutsegula ndi kuletsa torque. Mwachitsanzo, valavu yachipata chamadzi yomwe imayikidwa m'chipinda chopopera, pompano ya centrifugal ikayamba, kuthamanga kwa madzi kumakhala kwakukulu pamene valve yachipata sichitsegulidwa. Panthawiyi, momwe ma valve olowera pachipata chamadzi amachulukira, m'pamenenso ma torque amagwiritsidwa ntchito potsegula chipata. Makamaka ngati palibe kukakamiza mu payipi, kukakamiza kwa unilateral komwe valve yachipata imatha kupirira ndi yayikulu kwambiri. Panthawiyi, kasupe wa screw torsion amasinthidwa kuti atsegule ndi kutseka kwa valve pachipata, ndipo makina oletsa torque sali m'malo mwake. Valve yamagetsi yamagetsi yomwe imagwiritsidwa ntchito m'chipinda chopopera iyenera kusinthidwa kukhala malo otseguka otsekedwa, apo ayi n'zosavuta kuwononga valavu ya pachipata chifukwa cha madzi. Chifukwa valve yamagetsi yamagetsi yomwe imayikidwa panthawiyi ili pafupi ndi pompu yamadzi ya centrifugal, kuthamanga kwa madzi kumakhala kwakukulu komanso kosakhazikika. Panthawiyi, ngati valavu ya chipata sichinatsegulidwe bwino, ma valve ena a pachipata amagwedezeka kuchokera mbali ndi mbali chifukwa cha kayendedwe ka madzi, kotero kuti nkhope ya valve ya chipata imawonongeka, zomwe zimapangitsa kuti madzi a concave groove awononge moyo wautumiki. wa valve gate. Kuwonjezera kuyesera kupewa kugwiritsa ntchito valavu pachipata magetsi kusintha valavu, apo ayi n'zosavuta kuwononga chipata valavu pamwamba. Kuphatikiza apo, m'zaka zaposachedwa, ukadaulo wowongolera pafupipafupi kutembenuka kwapang'onopang'ono ukukula, kusintha kwapampu kumafunikira kugwiritsa ntchito ukadaulo wowongolera pafupipafupi kuti apulumutse mphamvu ndikuchepetsa utsi kuti apititse patsogolo magwiridwe antchito a pampu ya centrifugal.
2 Valve yachipata chamagetsi "otseguka, kutseka" kusintha kwa malo
Sinthani kutsegula ndi kutseka kwa mavavu a zipata zamagetsi. Malinga ndi malamulo osinthika a wopanga aliyense, valavu yachipata iyenera kutsekedwa pamanja ku gawo "lotsekedwa kwathunthu" kapena gawo "lotseguka". Ngati izi zimafuna kuti ang'ono ang'onoang'ono a valve gate kuti atseke ndi kutsegula nthawi ndi yochuluka, kapena yolemetsa kwambiri. Njira yatsopano yosinthira ikufotokozedwa apa mwatsatanetsatane: ngati tsinde la valavu ya chipata likudziwika, zidzakhala zosavuta kusintha valve yamagetsi pamene mukuyikonza. Masiku ano, tsinde la valavu yachipata yokhala ndi DN400-DN600 yopangidwa ku China nthawi zambiri imakhala 8mm, ndipo tsinde la valve yachipata yokhala ndi caliber pamwamba pa DN600 nthawi zambiri imakhala 10mm. Ngati ndi kotheka, funsani wopanga ma valve pachipata kuti mutalikirane. Pokonza valavu yoyendetsera magetsi, ngati mukudziwa malo a valavu yachipata pasadakhale, ngati mukudziwa kuti valavu ya pakhomo ili pamalo otsekedwa, muyenera kusintha gawo "lotsekedwa kwathunthu" poyamba. Choyamba, tembenuzani pamanja valavu yachipata kumalo oyambira, monga kuzungulira kuwiri kapena kumodzi kwa tsinde. Kenako lowetsani mphamvu yosinthira ndikudina batani "On". Yang'anani kutembenuka. Ngati kupatuka kwa tsinde la valavu kumagwirizana ndi kutembenuka kwa tsinde la valve pamene valavu imatsegulidwa pamanja malinga ndi batani lotsegulira, zimasonyeza kuti mzere wosalowerera wa galimotoyo umakhala wofanana ndi woyendetsa zipangizo zamagetsi. . Panthawiyi, njira yoyendetsera maulendo a valve yachipata iyenera kusinthidwa kukhala gawo lotsekedwa kwathunthu. Panthawiyi, potsegula valavu yachipata, werengani chiwerengero cha kutembenuka kwa tsinde la valve ya pakhomo kuti mudziwe ngati "otseguka". Ngati ndi valavu yamagetsi yamagetsi ya DN500, tsinde la dzino ndi 8mm, tsinde la valavu limazungulira kamodzi kuti litseguke 8mm, ndipo mbale ya valve yotsegula pakhomo iyenera kuchita masewera olimbitsa thupi 500mm, kotero kuti tsinde la valve lotseguka liyenera kuzungulira. 500/8 = 62.5 kutembenuka. Panthawiyi, kanikizani fungulo lotseguka la valve ndikuwerengera maulendo 63 a valve pachipata kuti mukhale "otseguka", sinthani gulu lamagetsi loyendetsa valavu, kuti malo osinthira osinthira "otseguka" akhale. Kuyambira pamenepo, valavu yamagetsi yamagetsi imatha kuzimitsidwa, kutsegulidwa ndikuyang'ananso, ndipo kusintha kwatha. Ngati valve yamagetsi yamagetsi ili pamalo otsegulira musanayambe kusintha, iyenera kusinthidwa kuti iyambe malo, ndondomekoyi molingana ndi zomwe zili pamwambapa.
3 Mafunso amene amafunsidwa kawirikawiri pambuyo pa kusintha
Chaka chimodzi valavu yachipata chamagetsi itagwiritsidwa ntchito, yang'anani ngati zomangira zomangira zomangira za torque zidagwa kapena kugwa. Makamaka, mndandanda wa ZD wa ma valve oyendetsa magetsi (monga momwe tawonetsera mu Chithunzi 4), ma valve ena amagetsi amagetsi amawonekera pogwiritsira ntchito, mapeto a pansi pa chipata amapindika ndi mbale ya valve kapena kumtunda kwa chipangizo chamagetsi chokhazikika. mbale yolumikiza nthiti yasweka. Chifukwa chiyani muli ndi makina ochepetsera ma torque, torque yochuluka ngati mulibe kaimidwe, musazimitse magetsi, chifukwa chake ndikuti cholumikizira chowongolera munjira yochepetsera torque ndichomasuka kumasula zomangira zowongolera. Kwa nthawi yayitali kumangitsa kasupe wa torsion, mpaka kugaya kasupe wa torsion, kuti makina ochepetsa mphamvu ya torque awonongeke, osasokoneza, zomwe zimatsogolera kungozi yachitetezo pachipata chamagetsi. Choncho, chaka chilichonse kuti aone ngati zomangira zokhazikika kugwa pansi, ngati zomangira anakonza kumasuka ayenera anamizidwa, ndi kupeza chifukwa kugwa pa dongosolo kulimbikitsa.
Buku - magetsi kusintha rocker amapereka kuti makina zida limagwirira n'zosavuta, zosavuta kutembenukira, pamene lophimba kwa Buku, kuonetsetsa kuti magetsi, ngati kulephera ngozi.
Kwa nthawi yayitali yochepa kwambiri yotseguka, valavu yotseka pachipata kuti ikhale yosinthika nthawi zonse, kuti muwonetsetse kuti ikugwiritsidwa ntchito moyenera. (Kusinthako kumaperekedwa miyezi itatu iliyonse).
