Kusarudzwa kwemagetsi evhavha yemagetsi emagetsi kunonyanya kuenderana nemusimboti wekuti kusarudzwa kwepetroleum nemakemikari emagetsi vharafu kunofanirwa kutevedzera.

Valve yemagetsi mudziyo chinhu chakakosha kuona kudzora chirongwa chevhavha, otomatiki kudzora uye kure kure. Maitiro ayo ekufambisa anogona kudzorwa nesitiroko, torque kana saizi yeaxial thrust. Nekuti maitiro ekushanda uye chiyero chekushandiswa kwevhavhavha yemagetsi mudziyo zvinoenderana nerudzi rwevhavha, iyo yekushanda yedhizaini uye chinzvimbo chevhavha mupombi kana michina, saka, kusarudzwa kwakaringana kwevhavha yemagetsi mudziyo kwakakosha kudzivirira kuitika kwekuremerwa (kushanda torque yakakwirira kupfuura torque yekudzora).
Kazhinji, kusarudzwa kwakaringana kwevhavha yemagetsi mudziyo unobva pane zvinotevera:
Operating torque Iyo inoshanda torque ndiyo huru parameter yekusarudza valve yemagetsi mudziyo. Iyo inobuda torque yechigadzirwa chemagetsi inofanira kunge iri 1.2 ~ 1.5 nguva dzeiyo yakakura inoshanda torque yevhavha.
Kune maviri makuru maitiro ekushanda kweiyo thrust valve electric device: imwe haina kugadzirwa ne thrust disc, yakananga yakabuda torque; Imwe yacho kugadziridzwa kweiyo thrust disc, iyo inobuda torque kuburikidza nekukanda disc stem nati mune inoburitsa inoburitsa.
Huwandu hwekutendeuka kweshaft yekubuda yevharuvha yemagetsi mudziyo une chekuita nedhayamita yezita revharuhu stem pitch uye nhamba yeshinda. Inoverengerwa zvichienderana neM=H/ZS (M ndiyo nhamba yese yekutendeuka kunofanirwa kusangana nemudziyo wemagetsi, H ndiko kureba kwekuvhura kwehunde yevharuvhu, S ndiyo inokwirisa yevhavha stem drive shinda uye Z ndiyo nhamba yevhavha stem thread).
Stem dhayamita ye-multi-turn open-stem mavharuvhu, kana dhayamita yedzinde yakakura inobvumirwa nemagetsi mudziyo isingakwanisi kupfuura nepakati pevharuvhu, haigone kuunganidzwa muvharuvhu yemagetsi. Naizvozvo, dhayamita yemukati yegomba rinobuda shaft yechigadzirwa chemagetsi chinofanira kunge chakakura kupfuura dhayamita rekunze rehunde yevharuvhu yakavhurika. Kune mavharuvhu etsvimbo yakasviba mumavharuvhu anotenderera uye akawanda-anotenderera mavharuvhu, kunyangwe zvisingakodzeri kufunga nezvekupfuura kwevhavha stem dhayamita, dhayamita yevharuvhu uye saizi yenzira yakakosha inofanirwa kutariswa zvizere mukusarudzwa, kuitira kuti gungano rinogona kushanda zvakajairika.
Kana iyo yekuvhura uye yekuvhara yekumhanyisa yevhavha yekubuda yakakurumidza, zviri nyore kugadzira mvura percussion phenomenon. Nokudaro, kuzarura kwakakodzera uye kuvhara nokukurumidza kunofanira kusarudzwa maererano nemamiriro akasiyana-siyana ekushandiswa.
Chigadzirwa chemagetsi chevhavha chine zvachinodiwa, ndiko kuti, chinofanira kukwanisa kudzikamisa torque kana axial simba. Kazhinji valve yemagetsi mudziyo inoshandisa torque inomisa shaft. Kana iyo yakatarwa yechigadzirwa chemagetsi yakatemwa, torque yayo yekutonga inotemwa. Kazhinji munguva yakafanotemerwa yekushanda, mota haizoremedzi. Asi kana mamiriro ezvinhu anotevera anogona kukonzera kuwandisa: kutanga, simba rekushandisa rakaderera, harigoni kuwana torque inodiwa, kuitira kuti motokari irege kutenderera; Chechipiri, hazvina kunaka kugadzirisa torque yekumisa mashandiro, kuitira kuti ive yakakura kudarika torque yakamira, zvichikonzera kuenderera kwakanyanyisa torque, kuitira kuti mota imire kutenderera; Chechitatu, kushandiswa kwepakati, kuchengetedza kwekupisa, kupfuura iyo inobvumirwa tembiricha kukoshesa kwemota; Chechina, kutadza kwedunhu kweiyo torque kudzikamisa mashandiro kunoitika nekuda kwechimwe chikonzero, zvekuti torque yakakura kwazvo; Chechishanu, ambient tembiricha yakawandisa, zvekuti kupisa kwemota kunodzikira zvishoma.
Kare, nzira yekudzivirira mota ndeye kushandisa fuses, overcurrent relays, thermal relays, thermostats, nezvimwewo, asi nzira idzi dzine zvakanakira uye nekuipa. Pamidziyo yemagetsi yakadai semichina inotakura zvinhu, kudzivirira kwakavimbika hakusipo. Nokudaro, kusanganiswa kwakasiyana-siyana kunofanira kutorwa, kupfupikiswa mumhando mbiri: imwe ndeyekutonga kuwedzera kana kuderera kwemagetsi ekupinza ikozvino; Chechipiri ndechekutonga mamiriro ekupisa emotokari pachayo. Chero nzira, kupisa kwemoto kwemota kunofanirwa kutariswa kune yakapihwa nguva yekubvumidza.
Kazhinji, nzira yekutanga yekudzivirira yekuremerwa ndeye: kune yakawandisa kuchengetedzwa kwekuenderera mberi kumhanya kana poindi yekushanda kwemota, iyo thermostat inoshandiswa; Nekudzivirira kwekuvhara mota, thermal relay inoshandiswa; Kune tsaona pfupi dzedunhu, fuse kana overcurrent relay inoshandiswa.
Petroleum, kemikari yemagetsi valve kusarudzwa kunofanira kutevera musimboti
Petroleum, kemikari yemagetsi valve kusarudzwa kunofanira kutevera musimboti
Pamberi pezvikamu zvakawanda zvevharuvhu yemagetsi uye zvakasiyana-siyana zvakasiyana-siyana, kusarudza pombi yegadziriro yekuisa yezvigadzirwa zvemagetsi emagetsi akakodzera, tinofanira kutanga tanzwisisa maitiro evhavha yemagetsi; Chechipiri anofanira kugona kusarudzwa kwemavharuvhu emagetsi matanho uye hwaro; Uyezve inofanirwa kutevedzera kusarudzwa kwepetroleum, indasitiri yemakemikari ine yemagetsi valve musimboti.
Kusarudzwa kwepetroleum, kemikari indasitiri yemagetsi valve musimboti: nzira inoyerera yakananga kuburikidza nevhavha yemagetsi, kuyerera kwayo kushoma kudiki, kazhinji inosarudza seyakagurwa uye yakavhurika svikiro nevhavha yemagetsi; Zviri nyore kugadzirisa kuyerera kwemagetsi mavharuvhu sekuyerera kwekudzora; Plug mavharuvhu uye bhora mavharuvhu anonyanya kukodzera reversing shunt; Kutsvedza kwechikamu chekuvhara pamwe chete nechisimbiso chepamusoro nekupukuta kwemagetsi evhavha yemagetsi ndiyo inonyanya kukodzera kune svikiro rine zvimedu zvakamiswa.
A, kucheka-kure uye yakavhurika svikiro yemagetsi mavharuvhu
Nzira yekuyerera yakananga kuburikidza nevhavha yemagetsi, kuyerera kwekudzivirira kuduku, kazhinji kunosarudzwa secheka-kubvisa uye kuzarura svikiro nevhavha yemagetsi. Kudzika kuvharwa kwemagetsi vharafu (globe valve, plunger valve) nekuda kweiyo tortuous kuyerera nzira, kuyerera kuramba kwakakwira kupfuura mamwe mavharuvhu emagetsi, saka sarudzo shoma. Muchiitiko chekubvumira kupikisa kwepamusoro, kuvhara kwemagetsi emagetsi kunogona kushandiswa.
Chechipiri, dzora kuyerera kwemavharuvhu emagetsi
Kazhinji sarudza nyore kugadzirisa valve yemagetsi seyekuyerera kwekutonga. Mavharuvhu emagetsi anovhara pasi, akadai semavharuvhu eglobhu, anokodzera chinangwa ichi nekuti saizi yechigaro chadzo inoenzanirana nekurohwa kwechinhu chinovhara. Rotary electric valves (plug, butterfly, bhora mavharuvhu) uye flex-body electric mavharuvhu (pinch, diaphragm) anogonawo kushandiswa throttling control, asi kazhinji chete muchikamu chidiki chemagetsi mavharuvhu calibers. Gedhi vharafu idhisiki-yakaita gedhi kune denderedzwa vharafu chigaro muromo kuita crosscutting kufamba, iyo chete padyo nenzvimbo yakavharwa, inogona kudzora zviri nani kuyerera, saka kazhinji haishandiswe pakuyerera kuyerera.
Yetatu, inodzosera shunt yemagetsi vharafu
Iri vharuvhu yemagetsi inogona kunge iine matatu kana anopfuura machani zvichienderana nekudiwa kwekudzosera shunt. Mavharuvhu epuragi nemabhora akanyatsokodzera chinangwa ichi, saka mavharuvhu emagetsi mazhinji anoshandiswa kudzosera shunt anoshandisa imwe yeaya mavharuvhu emagetsi. Asi mune dzimwe nguva, mamwe marudzi emagetsi emagetsi, chero bedzi maviri kana kupfuura mavharuvhu emagetsi akanyatsobatanidzwa kune mumwe nemumwe, anogonawo kushandiswa kudzosera shunt.
Ina, vharafu yemagetsi ine yakaturikwa zvimedu zvepakati
Kana pane zvakaturikwa zvimedu mukati, inokodzera valve yemagetsi ine sliding yekupukuta basa rekuvhara chikamu pamwe chete nechisimbiso chepamusoro. Kana kuseri nekumberi kwekufamba kwechidimbu chekuvhara kuchigaro kwakamira, saka inogona kusungirira zvimedu, saka iyi vharafu yemagetsi kunze kwekunge iyo yekuisa chisimbiso ichigona kubvumira embedding zvidimbu, zvikasadaro chete yakakodzera kune yakakosha midhiya yakachena. Bhora vharafu, plug vharafu, butterfly vharafu mukuita kwekuvhura nekuvhara zvine mhedzisiro yekupukuta pane yekuisa chisimbiso, saka yakakodzera kushandiswa mukati mepakati neyakaturikwa zvimedu.
Parizvino, ingave mu petroleum, kemikari, kana mune mamwe maindasitiri epipeline system, electric valve application, frequency yekushanda uye sevhisi inogara ichichinja, kudzora kana kubvisa kunyange kuderera kuderera, zvakakosha, midziyo yakakosha kana kuvimba nemavharuvhu emagetsi. Kudzora kwekupedzisira kwepombi ivhavha yemagetsi, vheji yemagetsi munzvimbo dzakasiyana-siyana dzebasa uye kushanda kwakavimbika ndiko.
