Sei zvichiitavharafu electric device ione overload phenomenon? Ndedzipi nzira dzekudzivirira?
Petrochemical, chiteshi chemagetsi, simbi uye mamwe maindasitiri zvinoda kuenderera, kutsetseka, kutenderera kutenderera kushanda. Naizvozvo, zvinoda kushandiswa kwevhavha kunofanirwa kuve nekuvimbika kwakanyanya, kuchengetedza chinhu chikuru, hachigone nekuti kutadza kwevhavha kwakakonzera kuchengetedzwa kwakakomba kwekugadzirwa uye tsaona yemunhu akakuvara, kusangana nezvinodiwa zvekumhanya kwenguva refu kwemidziyo, kuenderera kugadzirwa kunobatsira nguva yakareba, kuwedzera, kuderedza kana kudzivisa nekuda kwekuvhara kwevhavha, kugadzira mafekitari akachena uye akabudirira, kushandiswa kweHsE (hutano, kuchengeteka, zvakatipoteredza) kutarisira.
Kutanga, nheyo yekusarudza valve
(1) Kuchengeteka uye kuvimbika
Petrochemical, chiteshi chemagetsi, simbi uye mamwe maindasitiri zvinoda kuenderera, kutsetseka, kutenderera kutenderera kushanda. Naizvozvo, zvinoda kushandiswa kweiyovharafuinofanirwa kuve nekuvimbika kwepamusoro, kuchengetedza chinhu chikuru, haigone nekuti kutadza kwevharuvhu kwakakonzera kuchengetedzwa kwakakomba kwekugadzira uye tsaona yemunhu akakuvara, kusangana nezvinodiwa zvenguva refu yekumhanya kwemidziyo, kuenderera kugadzirwa kunobatsira kwenguva yakareba, mukuwedzera. , kuderedza kana kudzivirira nekuda kwekudonha kwevhavha, kugadzira mafekitori akachena uye akabudirira, kushandiswa kweHsE (hutano, kuchengeteka, nharaunda) kutarisira.
(2) Sangana nemaitiro ekugadzira zvinodiwa
Valve inofanirwa kusangana nekushandiswa kwepakati, kushanda nesimba, tembiricha yekushanda uye zvinodiwa zvekushandisa, izvo zvinonyanya kukosha zvekusarudzwa kwevharuvhu. Kudzivirirwa kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharu,kubvisa svikiro rekuchengetedza,kudiwa kwekudzivirira kuyerera kwepakati mukati mekushanda,kunofanira kushandisa cheki vharafu,otomatiki kubvisa mapombi emhepo uye midziyo mukuda kuenderera mberi. kubudisa mvura yakanyungudutswa, mhepo uye mamwe magasi asina-condensable, kudzivirira mhepo kutiza zvakare panguva imwe chete, inofanira kusarudza musungo. Mukuwedzera, kana iyo yepakati ichisvibisa, zvinhu zvine kunaka kwekusagadzikana kunofanirwa kusarudzwa.
(3) Kushanda kwakanaka, kuiswa, kuongorora (kugadzirisa) kugadzirisa
Mushure mokunge valve yaiswa, mufambisi anofanira kukwanisa kunyatsoona nzira yevhavha, chiratidzo chekuzarura, kuratidza chiratidzo, nyore kutarisana nezvikanganiso zvakasiyana-siyana zvekukurumidzira panguva yakakodzera uye inogadzirisa. Panguva imwecheteyo, yakasarudzwavharafuchimiro chemhando chinofanirwa kuve chimwechete sezvinobvira, nyore kuisa, kuongorora (kuchengetedza) kugadzirisa.
(4) Upfumi
Pasi pechikonzero chekusangana nekushandiswa kwakajairwa kwemaitiro mapaipi, mavharuvhu ane mutengo wakaderera wekugadzira uye chimiro chiri nyore chinofanira kusarudzwa sezvinobvira kuderedza mutengo wemidziyo, kudzivirira kutambisa mavharuvhu mbishi uye kuderedza mutengo wekuisa valve uye. kuchengetedza munguva inotevera.
Maviri, matanho ekusarudza vharafu
1. Sarudza mamiriro ekushanda kwevhavha maererano nekushandiswa kwayo mumudziyo kana nzira yepombi. Semuenzaniso, kushanda svikiro, kushanda nesimba uye tembiricha yekushanda.
2. Maererano nesvikiro rekushanda, nzvimbo yekushanda uye zvinodiwa nevashandisi kuti vaone giredhi rekuita chisimbiso chevhavha.
3. Sarudza rudzi uye nzira yekufambisa yevhavha maererano nekushandiswa kwayo. Rudzi senge truncation vharafu, regulating vharafu, kuchengetedza vharafu, imwe inokosha vharafu, etc. Dhiraivha sehonye giya, yemagetsi, pneumatic uye zvichingodaro.
4. Sarudza maererano nemazita emagetsi evhavha. Iyo yezita kudzvinyirirwa uye zviyero zvevhavha ichatemwa zvinoenderana neyakaiswa process piping. Ivhavha inoiswa mupombi yekugadzira, saka mamiriro ayo ekushandisa anofanirwa kuenderana nesarudzo yekugadzira pombi yepombi, iyo yakajairwa sisitimu inoshandiswa nepombi uye kudzvanywa kwezita repombi inotemwa, iyo valve nominal pressure, saizi yezita, dhizaini yevhavha uye zviyero zvekugadzira zvinogona kutsanangurwa. Mamwe mavharuvhu akavakirwa pane yakatarwa nguva inoyerera kuburikidza nevharuvhu kana kusimuka kwezita rehukuru hwevharuvhu.
5. Sarudza fomu yekubatanidza yevhavha yekupedzisira chiso uye pipeline maererano nemamiriro chaiwo ekushanda uye hukuru hwezita revhavha. Zvakadai seflange, welding, clamping kana shinda, nezvimwe.
6. Maererano nenzvimbo yekuisa yevhavha, nzvimbo yekuisa, saizi yezita kuti uone chimiro chechimiro cherudzi rwevhavha. Zvakadai seyakasviba tsvimbo yegedhi vharafu, Angle globe vharafu, yakagadziriswa bhora vharafu, nezvimwe.
7. Zvinoenderana nehunhu hwepakati, kumanikidza kushanda uye tembiricha yekushanda, kusarudza nenzira kwayo uye zvine musoro zvinhu zvevhavha goko uye zvikamu zvemukati.
Sei mudziyo wemagetsi wevharuvhu uchiita sewakawandisa? Ndedzipi nzira dzekudzivirira?
Chigadzirwa chemagetsi chevhavha ndechekuziva kudzora kwevharuvhu, otomatiki kudzora uye kure kure kudzora kunokosha zvishandiso, mafambiro ayo anogona kudzorwa nesitiroko, torque kana axial thrust size. Nekuti maitiro ekushandisa uye chiyero chekushandisa chevhavha yemagetsi mudziyo zvinoenderana nerudzi rwevharuvhu, chigadziriso chinoshanda uye chinzvimbo chevhavha mupombi kana midziyo, saka, kusarudzwa kwakaringana kwevhavha yemagetsi mudziyo kwakakosha kudzivirira. overload phenomenon (iyo torque inoshanda yakakwira kupfuura torque yekudzora). Nekudaro, inogona kuremerwa kana:
1, magetsi akadzikira, haakwanise kuwana torque inodiwa, zvekuti mota inomira kutenderera.
2, zvisizvo kuseta torque yekuganhura michina, kuitira kuti ive yakakura kupfuura yekumisa torque, zvichikonzera kuenderera mberi kwechizvarwa chetorque yakakura, zvekuti mota inomira kutenderera.
3, senge poindi yekushandiswa kwepakati, kupisa kunogadzirwa kumusoro, kupfuura inobvumidzwa tembiricha yemota.
4, nekuda kwechimwe chikonzero iyo torque inodzikamisa dhizaini kutadza, zvekuti torque yakakura kwazvo.
5, kushandiswa kweambient tembiricha yakanyanya kukwira, zvinoita kuti injini yekupisa simba iderere.
Izvo zviri pamusoro ndezvimwe zvikonzero zvekuremedza, nekuda kwezvikonzero izvi chiitiko chekupisa kwemota kunofanirwa kutariswa pachine nguva, uye kutora matanho ekudzivirira kuwandisa. Munguva yakapfuura, nzira yekudzivirira mota ndeye kushandisa fuse, overcurrent relays, thermal relays, thermostatic zvishandiso, nezvimwewo, asi nzira idzi dzinewo zvadzo zvakanakira nekuipira. Kune zvigadzirwa zvemagetsi zvine mutoro wakasiyana, hapana nzira yekudzivirira yakavimbika.
Naizvozvo, musanganiswa wemitoo unofanira kugamuchirwa. Zvisinei, nekuda kwekuremerwa kwakasiyana kwechigadziro chemagetsi chimwe nechimwe, zvakaoma kuisa mberi nzira yakabatana. Asi kazhinji kacho, panowirirana panogona kuwanikwa.
Iyo nzira dzekudzivirira dzakawandisa dzinogamuchirwa dzinogona kupfupikiswa mumhando mbiri:
1. Tongai kuwedzera kana kuderera kwemotokari inopinza ikozvino;
2. Tongai kupisa kwemota pachayo. Idzi nzira mbiri dziri pamusoro, zvisinei kuti ndedzipi dzinofanirwa kufunga nezvekupisa kwemota yakapihwa nguva margin. Zvakaoma kuita kuti ienderane nehupi hwekupisa hunhu hwemota nenzira imwechete.
Naizvozvo, isu tinofanirwa kusarudza musanganiswa wenzira dzinobva pane zvakavimbika chiito zvinoenderana nechikonzero chekuremedza kuti tiwane yakaringana kudzivirira kuwanda. Iyo mota yeRotock electric mudziyo, nekuti yakanyudzwa mumhepo ye thermostat ine imwechete insulation level yemota, kana iyo yakayerwa tembiricha yasvika, iyo mota yekudzora loop ichagurwa. Iyo yekupisa simba ye thermostat pachayo idiki, uye yayo-yenguva-inogumira maitiro anotarirwa neaya ekupisa masimba maitiro emota, saka iyi inzira yakavimbika.
Nzira dzekutanga dzekudzivirira dzekuremesa ndeidzi:
1, iyo mota inoramba ichishanda kana poindi yekudzivirira yakawandisa uchishandisa thermostat;
2. Thermal relay inoshandiswa kuchengetedza motokari inovhara
3. Fuse kana overcurrent relay inoshandiswa panjodzi yedunhu pfupi. Sarudzo chaiyo yevhavha yemagetsi mudziyo uye kudzivirira kuwandisa kwakabatana uye kunofanirwa kutariswa.
