Chii chinonzi Gate Valve
A vharuvhu yegedhiinodzora kuyerera kwemvura nekusimudza kana kudzikisa gedhi (wedge) rakamira. Rakagadzirirwamabasa akazara ekuvhura/kuvhara- kwete kudzorwa kwemvura - haipe simba rakawanda rekudzivirira kuyerera kwemvura uye inovhara zvakanyanya. Inoshandiswa zvakanyanya mumafuta/gasi, mafekitori emakemikari, uye kugadzira magetsi, kuvimbika kwayo kunoita kuti ive yakakosha kune masisitimu ekuchengetedza.
Nheyo yekushanda kwevharuvhu yegedhi
Gedhi rinofamba rakanangana nekuyerera kwemvura. Kana rakasimudzwa zvizere, rinobvumira kuyerera kusina muganho; kana rakadzikiswa, rinoita kuti pave nechisimbiso chakasimba pazvigaro zvevharuvhu.Usambovhura zvishomamavharuvhu egedhi - izvi zvinokonzera kukurwa kwechisimbiso uye kukuvara kwekuzunguzika.
Matanho Mashanu Akakosha Ekuchengetedza Mavharuvhu Egedhi
Kuchengetedza kwakakodzera kunodzivirira ngura uye kunoita kuti mavharuvhu ekuchengetedza ashande kana zvichidikanwa.
1. Nzvimbo Yakakodzera Yekuchengetera Zvinhu
–Mukati & Munzvimbo YakaomaChengeta munzvimbo dzakavharwa, dzisina hunyoro hwakanyanya (<60% RH).
–Dzivisa Zvinokuvadza: Chengeta kure nemakemikari, munyu, kana utsi hune acid.
–Kudzora Tembiricha: Chengetedza 5°C–40°C (41°F–104°F).(Tarisa ISO 5208 standard: Hunyoro hwakanyanya hunogona kukonzera ngura muzvikamu zvesimbi uye kukwegura kwezvisimbiso zverabha.)
- Mavharuvhu makuru nemadiki anofanira kuchengetwa zvakasiyana:Mavharuvhu madiki anogona kuiswa pamasherufu, uye mavharuvhu makuru anofanira kurongedzwa zvakanaka pasi peimba yekuchengetera zvinhu, ukuwo achiona kuti pamusoro pechisungo cheflange hapabate pasi.
- Kuchengeta mavharuvhu panze:Unofanira kuva nechokwadi chekuti waafukidza nezvinhu zvisingapindi mvura uye zvinodzivirira guruva, zvakaita setarpaulin, linoleum, nezvimwewo. (Kana mamiriro ezvinhu achibvumira, zvinokurudzirwa kuti usaachengete panze)
Mazano:Chengeta vharuvhu yegedhi mumba uye chengeta imba yakaoma uye ine mhepo inofema.
2. Kugadzirira Vharuvhu
–Vhara Gedhi: Inodzivirira kupinda kweguruva.
–Zviteshi zveSimbiso: Shandisa zvivharo zvePVC kana mapulagi akaputirwa newakisi pamaflanges.
–Mafuta Matanda: Isa mafuta emhando yepamusoro padzinde dzakaonekwa.
Mazano:Magumo ese ari maviri enzira anofanira kuvharwa nepepa rewakisi kana mapepa epurasitiki kudzivirira tsvina kupinda.
3. Protocol Yekuchengetedza Kwenguva Refu
–Kuongororwa Kwekota: Tarisa kana paine ngura, chivharo chakasimba, uye mafuta anozorwa.
–Tenderedza Mavhiri Emaoko: Tendeudza 90° mwedzi mitatu yega yega kudzivirira kubatwa.
–Magwaro: Mavharuvhu etag ane zuva rekuchengetera uye magwaro ekuongorora.
- Kurapa kwekudzivirira ngura:
1. Mavharuvhu esimbi (akadai semavharuvhu egedhi nemavharuvhu ekumisa) anofanira kuputirwa nemafuta anodzivirira ngura kana mafuta, kunyanya nzvimbo dzeflange, majoini ane shinda nezvimwe zvikamu zvinokurumidza kuoxidized.
2. Kana ikachengetwa kwenguva yakareba (inopfuura mwedzi mitanhatu), zvinokurudzirwa kuti utarise uye uwedzere mushonga unodzivirira ngura pamwedzi mitatu (zvinoenderana neAPI 598 standard).
4. Vharuvhu yeSimbi Isina Stainless neCarbon Yakasiyana
- Njodzi yeKuora kweGalvanic:
1. Kubata + hunyoro zvinogadzira sero remagetsi.
2. Simbi yekabhoni inova anode, ichiora nekukurumidza.
3. Simbi isina ngura (cathode) ine jira rayo rekudzivirira rakakuvara, zvichiita kuti ngura ikurumidze kupararira mune ramangwana.
- Kutama kweKabhoni (Kuchinja kweCarburization):
1. Kubata zvakananga kunoita kuti maatomu ekabhoni afambe kubva musimbi yekabhoni kuenda musimbi isina ngura.
2. Izvi zvinokanganisa chimiro chesimbi isingatsvi, zvichideredza zvakanyanya kuramba kwayo ngura.
- Maitiro Akanakisisa Ekuchengetedza:
1. Nzvimbo Yokuchengetera Yakasiyana: Chengeta munzvimbo dzakasiyana nguva dzose.
2. Kureba Kudiki: Chengeta daro rinenge masendimita makumi mashanu (20 inches), kunyanya munzvimbo dzine hunyoro.
3. Kubata Kwenguva Pfupi: Shandisa zvidziviriro zvakaoma, zvisingafambise mhepo (huni, purasitiki, rabha) kana zvinoputira zvinodzivirira.
5. Mitemo Yakakosha Yekugadzirisa Kuchengetedzwa Kwemavharuvhu
- Kuzivikanwa kweKunyora Mavara
• Mavharuvhu esimbi isina ngura → Tepi yebhuruu
• Mavharuvhu esimbi yekabhoni → Tepi yeyero
Inodzivirira zvikanganiso zvekutarisira maziso uye ngura yegalvanic.
- FIFO Warehouse Zoning
• Nzvimbo dzakatsaurirwa dzekuchengetera zvinhu dzinoita kuti munhu akwanise kutenderera ari muFirst-In-First-Out
• Inobvisa kusashanda kwemidziyo (yakakosha pamavharuvhu ekuchengetedza)
- Kupatsanurana Kwekuchengetedza Mari
• Bvisa mavharuvhu esimbi isingatsvi (zvinodhura 3-5x kupfuura)
• Inodzivirira kushandiswa zvisina kunaka netsaona uye kukuvara kwengura
- Kuitwa kweUinjiniya
• Tsanangudzo yeNzira
• Nzvimbo yekuisa zvikamu ≥500mm pakati penzvimbo
• Kupatsanurwa kwerabha kusina kufambisa electrochemical 8-10mm
*Kutevedzera mitemo: Inosangana nezvinodiwa zveGB/T 20878-2017.*
Mazano Akakosha Ehunyanzvi
• Magiredhi ezvigadzirwa zveLaser-etch (semuenzaniso, "WCB") pamiviri yemavharuvhu
• Chengetedza <45% RH munzvimbo dzekuchengetera zvinhu
• Mavharuvhu egedhi rekuchengetedza akamira - kurongedza kwakatwasuka kunokanganisa kuvharwa kwenjodzi
Kuenzanisa Nzira dzekuchengetedza dzeBackup Gate Valve
Kugadziriswa kweVharuvhu yeGedhi: Maitiro mana Akakosha
1. Kutarisirwa Kwebasa Kwenguva Dzose
–Nyora Mashinda: Isa molybdenum disulfide paste kunzungu dzedzinde kota imwe neimwe.
–Kunze Kwakachena: Pukuta tsvina/marara mwedzi wega wega nemachira asingasvibisi.
–Tarisa Mavhiri Emaoko: Sunga mabhaudhi akasununguka nekukasika kuti usakanganiswa.
2. Kurongedza/Kugadzirisa Gland
–Ongorora Kota: Tsvaga panobuda mvura yakatenderedza tsinde.
–Gadzirisa Nzungu dzeGland: Simbisa zvishoma nezvishoma kana kuchema kukaitika –usadzvanya zvakanyanya.
–Tsiva KurongedzaShandisa tambo yakanyudzwa negirafiti makore maviri kusvika mashanu ega ega.
3. Maitiro Akanakisisa Ekushandisa Mafuta
| Dambudziko | Mhinduro |
| Kusazora mafuta zvakakwana | Isai mafuta kusvika abuda muzvisimbiso |
| Kuzora mafuta zvakanyanya | Mira kana kuramba kuchiwedzera (3,000 PSI) |
| Girisi Yakaoma | Sukurudza neparafini usati waisa mafuta zvakare |
4. Kutarisirwa kweSisitimu yeKutapurirana
–Mabhokisi egiya: Chinjai oiri gore rega rega (ISO VG 220 inokurudzirwa).
–Zvishandiso zvemagetsi: Tarisai zvisimbiso zvehunyoro kaviri pagore.
–Kudzoserwa Kwemashoko Nemaoko: Bhasikoro mwedzi wega wega kudzivirira pfari.
Mazano Akakosha Ekuchengetedza Mavharuvhu
–Rubatsiro rweKumanikidzwa: Vhura maplug ekudhonza mvura usati waisa mafuta kuti usaputike nemhepo.
–Kuisa nzvimbo: Mavharuvhu egedhi rekuchengetedzayakavharwa zvizerekuchengetedza zvisimbiso zvakabatirira.
–Zvishandiso zveEmergency: Chengeta zvishandiso zvekurongedza zvimwe zvinhu pamwe nenzungu dzegland pedyo.
Mhedziso: Kuwedzera Nguva Yehupenyu hweVharuvhu
Tevedzera mitemo iyi yekudzivirira mavharuvhu egedhi akavimbika:
1. Kuchengetera= Yaoma, yakavharwa, uye yakanyorwa.
2. Kugadzirisa= Kuzora mafuta kwakarongwa uye kuongororwa.
3. Kugadzirisa= Gadzirisa kubuda kwemvura nekukasika.
Nekuisa pamberi pekutarisira kwekukurumidza, unodzivisa 80% yekukundikana kwemavharuvhu - zvakakosha kune masisitimu enjodzi.
