Chigadzirwa cheFisher pasi paEmerson chinotarisa pamavharuvhu ekudzora maitiro, ayo anoshandiswa zvakanyanya mumafuta, gasi, makemikari nedzimwe nzvimbo.

Schlumberger, USA:

Cameron ari pasi paSchlumberger anopa mavharuvhu nemidziyo yekubvisa matsime emumaindasitiri emafuta negesi.

Flowserve, USA:

Inopa mavharuvhu akasiyana-siyana emaindasitiri, anosanganisira mavharuvhu ekudzora, mavharuvhu ebhora, mavharuvhu emashavishavi, nezvimwewo, zvichishandira maindasitiri emagetsi, makemikari uye ekurapa mvura.

Tyco International, USA:

Brand yayo yeTyco Valves & Controls inopa mavharuvhu ekudzivirira moto, maindasitiri uye mabhizinesi.

KITZ, Japan:

Imwe yemakambani makuru ekugadzira mavharuvhu muJapan, ine zvigadzirwa zvinofukidza maindasitiri, zvekuvaka uye zvevashandi.

IMI, UK:

IMI Critical Engineering inotarisa pamavharuvhu emhando yepamusoro emaindasitiri, achishandira maindasitiri esimba, simba uye makemikari.

Crane, USA:

Kambani yayo yeCrane ChemPharma & Energy inopa mhinduro dzemavharuvhu kumaindasitiri emakemikari, petrochemical uye esimba.

Velan, Kanada:

Inotarisa pamavharuvhu emuindasitiri, anosanganisira mavharuvhu egedhi, mavharuvhu ebhora, mavharuvhu eshavishavi, nezvimwewo.

KSB, Germany:

Inopa mhinduro dzepombi nemavharuvhu, dzinoshandiswa zvakanyanya mukurapa mvura, simba uye maindasitiri.

Boka reWeir, UK:

Chiratidzo chayo cheWeir Valves & Controls chinotarisa pamavharuvhu anoshanda zvakanyanya mumigodhi, magetsi, mafuta negesi.

Mazano:NMugadziri wevharuvhu yeSWikambani inozivikanwa zvikuru inotengesa mavharuvhu ekudzima magetsi muChina. Vane fekitori yavo yekuvaka mavharuvhu ekudzima magetsi uye fekitori yekuisa mavharuvhu ekudzima magetsi. Vanogona kukupa rutsigiro rwehunyanzvi uye mitengo yefekitori yekuvhara mavharuvhu.

Vharuvhu Yekudzima (SDV)

Chii chinonzi Shutdown Valve (SDV)

Vharuvhu yekudzima imhando yeactuator mu automation system. Inosanganisira multi-spring pneumatic diaphragm actuator kana floating piston actuator uye regulating valve. Inonyanya kushandiswa kudimbura kana kubatanidza mvura iri mupaipi nekukurumidza (senge gasi, mhepo inopisa, mhepo inotonhora uye flue gas, nezvimwewo). Inoshandiswa zvakanyanya muindasitiri yekuchengetedza maindasitiri uye kugadzirisa tsaona dzenjodzi.

Basa guru uye musimboti wekushanda kwevharuvhu yekuvhara

Basa guru revharuvhu yekudzima nderekucheka nekukurumidza, kubatanidza kana kuchinja mvura iri mupaipi nekugamuchira chiratidzo chechishandiso chinodzora (senge alarm yekumanikidza, tembiricha kana kubuda kwemvura). Mashandiro ayo akajairika anosanganisira:

Chinokonzeresa chiratidzo:Kana sensor ikaona chimwe chinhu chisina kujairika (sekubuda kwegasi, kumanikidzwa kunopfuura muganho), chiratidzo chinotumirwa kuactuator.

Mhinduro yemakanika:Diaphragm kana kuti piston mechanism inofambisa muviri wevharuvhu kuti ufambe (semuvharuvhu webhora, vharuvhu yechigaro chimwe chete), ichichinja mamiriro ekuvhura nekuvhara kwevharuvhu.

Kiyi yekuchengetedza:Mushure mekunge vharuvhu yekuvharwa kwekukurumidza yavharwa, inowanzogadzirwa kuti ive iri mumamiriro ekuzvikiyira yega kudzivirira kuvhurwa netsaona.

Mhando huru uye mamiriro ekushandisa kwevharuvhu yekudzima

Mavharuvhu ekudzimainogona kukamurwa kuita mhando dzinotevera dzakajairika zvichienderana nechimiro chavo nechinangwa chavo:

‌Mavharuvhu ekuvhara akajairika:Inoshandiswa kudzora mashandiro emaindasitiri (senge indasitiri yemakemikari nesimbi), kunyanya ichishandisa vharuvhu yebhora kana chimiro chevharuvhu yemaoko kuti iwane mutemo wepakati nepakati wekudzimwa kwemhepo.

Vharuvhu yekuvharwa kwekukurumidza:yakatsaurirwa kumasisitimu ekuchengetedza (akadai semapaipi egasi uye masisitimu eSIS), ine kumhanya kwekupindura nekukurumidza uye basa rekuzvivharira rega kudzivirira tsaona kuti dzisakure.

Vharuvhu yekuvharira diaphragm yepneumatic:vharuvhu inodzorwa nediaphragm inofambiswa nemhepo inomanikidzwa, iyo yakakodzera mamiriro ekudzora otomatiki ari kure (senge maindasitiri emafuta nemagetsi).
