Kutenderera kwekupisa kunokonzera kushushikana kusingaperi kwemidziyo yemukati. Zvigaro zvakapfava zvemazuva ese (PTFE chaiyo kana RPTFE yakazara negirazi) zvinotanga kudonha, kukambaira, uye kukanganisika zvachose pamusoro pe180°C. Kana rin'i yechigaro yarasikirwa nekugadzikana kwehukuru hwayo, kuchekwa kwemhepo kunoitika kana mafuta ekupisa anodonhera mudumbu, zvichikonzera njodzi dzekuchengetedza uye kuvharika kusina kurongwa.

3. Zvigaro zvePPL: Nzvimbo Inotapira ye200–280°C

Chii chinonzi PPL?

PPL (Polyphenylene Phenylate) ipurasitiki inoshanda zvakanyanya yakagadzirwa kuti ikwanise kutsungirira kupisa kwakanyanya. Kusiyana nePTFE (inonyorovesa pa180°C) kana RPTFE (yakaganhurirwa pa220°C), PPL inoramba yakasimba, yakasimba, uye inodzivirira kukwira kusvika pa280°C.

Maitiro Akanaka

Masisitimu emhepo yakaguta- misoro mikuru nemitsetse yemapazi inosvika kuKirasi 300/600.
Zvidimbu zvemafuta ekupisa– macircuit ekuchinjana kupisa anoshandisa zvicherwa kana ma fluids ekugadzira (semuenzaniso, Dowtherm™, Therminol®) pasi pe 280°C.
Mvura yekubikira bhaira– mvura inopisa ine simba guru inoda kuvharwa zvakasimba.

Sei Uchifanira Kusarudza Zvigaro zvePPL Pane zveSimbi Munzvimbo Ino?

Kuvhara zvakasimba kwebubble chaiyo– Kuchengetedzwa kwePPL kunoita kuti API 598 Rate A isaburitse mvura; zvigaro zvesimbi zvinoita kuti mvura ibude zvishoma.
Kuchengetedza mari yakawanda- Vharuvhu yePPL yeClass 300 trunnion ine 4 inches inowanzodhura60% zvishomakupfuura chinhu chakaenzana nacho chigere musimbi.
Mari shoma yekushanda- kukweshana kushoma kunoderedza saizi ye actuator, zvichichengetedza kubatanidzwa kwe skid.

Muganho weinjiniya:Usapfuure 280°C nguva dzose—kuora kwekupisa kunokonzera kupwanyika uye kutsemuka kudiki.

4. Zvigaro zveSimbi: Kana Tembiricha Yapfuura 280°C

Tekinoroji Inoshanda Zvakasimba

Pamusoro pe 280°C, zvigaro zvesimbi chete ndizvo zvinosara. Kuomesa pamusoro zvakanyanya kwakakosha:

Stellite® (yakavakirwa pa cobalt)- kudzivirira kupisa kwakanyanya uye kutsamwa, zvakanaka kwazvo pakushandisa utsi hwemhepo.
Kabhoni yeChrome kuburikidza neHVOF– kuomarara 68–70 HRC, kusingapindike nezvidimbu zvinokwenya mumafuta anodziya.
Tungsten kabhayidhi- Kusapfeka kwakanyanya kusvika 400°C.

2. Kuderedza Kumanikidzwa Kwemaburi (Kunokosha Pamafuta Anodziya)

Mvura inopisa inokura zvakanyanya kana yakavharirwa mugomba remuviri rakavharwa. Pasina rubatsiro, kumanikidzwa kunogona kupwanya muviri kana kuputitsa zvigaro. Taurazvigaro zvinozvinyaradza(mugumisiro wepiston imwe chete) kana maburi ekuenzanisa mukati.

3. Dhizaini Inodzivirira Moto (API 607 / ISO 10497)

Pamafuta anobatidza moto, mavharuvhu anodzivirira moto ane chisimbiso chechipiri chesimbi kubva kusimbi kuenda kusimbi. Kana chigaro chePPL chikatsva panguva yemoto, kumanikidzwa kwemutsara kunosundira bhora pamuromo wesimbi uyu kudzivirira kubuda kwemvura.

Danho 1 - Kutevedza Zvinhu– Mishumo Yechokwadi Yekuyedza Chigayo ine nhamba dzekupisa dzakadhindwa pamuviri (ASTM A216 WCB kana A351 CF8M).

Danho rechipiri - Kuedzwa kweTemp Yepamusoro– Kuongororwa kwemvura kwakajairika kunogona kusaratidza maitiro ezvigaro pa250°C. Kumbira bvunzo dzekupisa gasi kana thermal cycling pamapoka emuenzaniso.

8. Mibvunzo Inowanzo bvunzwa

Mubvunzo 1: Zvigaro zvePPL zvinogona kushandiswa here pamafuta ekupisa ekugadzira pa300°C?

Nhamba 300°C inodarika chiyero chekuora kwePPL (280°C). Kuomarara kwekupisa nekutsemuka kunokonzera kutadza kushanda kwechisimbiso nekukurumidza - unofanira kushandisa vharuvhu inogara simbi.

Mubvunzo wechipiri: Ndeipi nzira inobvumidzwa yekubuda kwesimbi inobvumirwa nemavharuvhu ebhora eAPI 6D ane simbi?

Mavharuvhu ane simbi anowanzo shandiswa seISO 5208 Rate C/D kana ANSI/FCI 70‑2 Class IV–VI. Kana uchida kudzimwa kwemhepo zvine simba, taura nezveClass VI (yakaenzana nebubble tight nezvigaro zvesimbi zvakapetwa).

Mubvunzo wechitatu: Sei mavharuvhu emhepo achikundikana zvakanyanya panguva yekutanga kwemagetsi kwakaoma?

Kutonhora kwemvura mumitsetse kunokonzera kuvhunduka kwakanyanya kwekupisa uye mvura inoyerera kana utsi hunopisa hwasvika. Kubata utsi zvakanaka uye kuchekwa kwemvura kunodzivirira kukurwa (PPL kana Stellite) kunodzivirira kukuvara kwekutanga.

Mubvunzo wechina: Ndeapi maburi emuti akakodzera 400°C ane hutsi hwakanyanya kupisa?

Graphite yakawedzerwa inochinjika ine mhete dzecarbon fiber dzakarukwa dzinodzivirira kubuda kwemhepo dzinosvika 550°C. Kurongedza kwePTFE hakufanirwe kushandiswa pamusoro pe200°C.
