Guhitamo Valve z'Ubushyuhe Bukabije: Valve z'umupira za PPL vs. Zicarwa mu byuma kuri sisitemu y'amavuta ashyushye n'umwuka ushyushye

1. Ikibazo cy'ubushyuhe bwinshi

Gukoresha imiyoboro y'amavuta ashyushye cyangwa imiyoboro ikwirakwiza umwuka ushyushye cyane biri mu nshingano zihanishwa cyane umuntu uwo ari we wesevalve y'umupira w'ubushyuhe bwinshiIyo ubushyuhe bw'imikorere buri hagati ya 200°C na 550°C, valve zisanzwe zipfa vuba—kandi zigapfa buhenze.

Guhindagurika kw'ubushyuhe bitera imbaraga zidasanzwe mu byuma bigize imbere. Intebe zisanzwe zoroshye (PTFE cyangwa RPTFE yuzuye ikirahure) zitangira gucika intege, guhindagurika no kwangirika burundu hejuru ya 180°C. Iyo impeta y'intebe itakaje ubushobozi bwo kuguma mu buryo buhamye, umwuka uca mu kirere cyangwa amavuta y'ubushyuhe agasohoka mu mubiri, bigatera ibyago mu mutekano no kuzimya ibintu bitateganijwe.

Nyamara gukabya si cyo gisubizo. Amatsinda menshi ashinzwe gutanga amasoko ahitamo ibyuma byicayeho kuri serivisi iyo ari yo yose irengeje dogere selisiyusi 200, atekereza ko ari yo nzira yonyine itekanye. Ibi bikunze kongera amafaranga akoreshwa mu gushora imari mu300%–400%hatabayeho inyungu nyazo ku bushyuhe buringaniye.

Icyiza cy'ubwubatsi ni ugusobanukirwa imbibi ziri hagatiIntebe zoroshye za PPL (Polyphenylene Phenylate)naintebe z'icyuma zikomeye—kuringaniza uburyo amazi adasohoka neza, uburyo bwo kwizera igihe kirekire, n'ingengo y'imari y'umushinga.

2. PPL vs. Metal-Cloves Ball Valves – Kugereranya byihuse

3. Intebe za PPL: Ahantu heza ho gupima ubushyuhe bwa 200–280°C

PPL ni iki?

PPL (Polyphenylene Phenylate) ni thermoplastic ifite imikorere myiza yakozwe kugira ngo ikomeze ubushyuhe. Bitandukanye na PTFE (yoroshya kuri 180°C) cyangwa RPTFE (igarukira kuri 220°C), PPL igumana ubukana bwa mekanike, imbaraga zo gukanda, no kudakora neza kugeza ku280°C.

Porogaramu nziza

• Sisitemu z'umwuka wuzuye– imitwe y'ingenzi n'imirongo y'amashami kugeza ku cyiciro cya 300/600.
• Uduce tw'amavuta ashyushye– imiyoboro ihindura ubushyuhe ikoresha amabuye y'agaciro cyangwa amazi ya sintetike (urugero, Dowtherm™, Therminol®) munsi ya 280°C.
• Amazi yo kugaburira icyuma gishyushya– amazi ashyushye afite umuvuduko mwinshi asaba kuzimwa cyane.

Kuki wahitamo intebe za PPL kuruta iz'icyuma muri aka gace?

1. Gufunga neza kw'ibipupe– Ubuyobozi bwa PPL bworoshye butuma API 598 Rate A itakaza amazi; intebe z'icyuma zo mu bwoko bwa ceramic zituma amazi amwe asohoka.
2. Kuzigama amafaranga menshi– Valve ya PPL ya santimetero 4 ya Class 300 trunnion ikunze kugurwaBigabanutseho 60%kurusha icyuma gihwanye na cyo.
3. Ibiciro byo gukoresha ibikoresho biri hasi- kugabanuka guke bigabanya ingano y'icyuma gitera imbaraga, bigatuma amazi agabanuka.

4. Intebe z'icyuma: Iyo ubushyuhe burenze 280°C

Ikoranabuhanga rigoye

Hejuru y'ubushyuhe bwa 280°C, intebe z'icyuma ni zo zirokoka. Gukomera ku buso cyane ni ngombwa:

• Stellite® (ishingiye kuri cobalt)– gushyuha cyane no kudakomera, ni byiza cyane ku mwuka w'ubushyuhe.
• Karubide ya Chrome ikoresheje HVOF– ubukana bwa 68–70 HRC, butabangamira uduce duto two mu mavuta ashyushye.
• Karubide ya Tungsten– Ubudahangarwa bukabije bwo kwangirika kugeza kuri 400°C.

Indishyi zo mu mpeshyi ya Belleville

Kwagura ubushyuhe ni ikibazo gikomeye. Mu gihe cyo gutangira gukora ibintu bishyushye, umupira urushaho kwaguka vuba kurusha umubiri. Imiterere y'abahanga mu bushyuhe buri hejuru irimoIntebe zuzuye impeshyi za Bellevillebikomeza gufunga igitutu mu gihe bireka kugenda mu ruhande rw'imbere kugira ngo bihuze n'ihungabana ry'ubushyuhe.

Serivisi zisanzwe (>280°C)

• Imashini zishyushye cyane mu nganda zitanga amashanyarazi.
• Amatanura ya peterolikemike n'ubushyuhe bwa asphalt (300–450°C).
• Imirongo ya katalisiti iteye ubwoba ifite ibintu bikomeye byashyizwemo.

5. Ibintu by'ingenzi mu gushushanya imiterere y'ubuhanga mu mavuta ashyuha n'umwuka ushyushye

Ibikoresho by'intebe ni kimwe cya kabiri cy'inkuru. Ibi bintu by'inyongera ni ingenzi cyane:

1. Ipaki irwanya gutwika no gupakira ibintu bizima

Uburyo bwo gushyuha butuma ibintu bikoreshwa mu gupakira grafiti uko igihe kigenda gihita.gupakira ibintu byose birihohamwe n'imashini zo kumesa za Belleville zihora zikanda impeta za grafiti, zigakomeza imbaraga zo gufunga zidafunze n'intoki.

2. Kugabanya umuvuduko w'ubushyuhe mu mwobo (Ni ngombwa cyane ku mavuta ashyushye)

Amavuta ashyushye yiyongera cyane iyo afatiwe mu mwobo ufunze. Iyo hatabayeho kuruhuka, igitutu gishobora gushwanyagura umubiri cyangwa kwicara mu ntebe. Sobanuraintebe zo kwiyima(ingaruka ya piston imwe) cyangwa imyobo yo kuringaniza imbere.

3. Igishushanyo mbonera cy’ubuziranenge ku nkongi y’umuriro (API 607 ​​/ ISO 10497)

Ku mavuta ashyushye ashobora gushya, uturinda umuriro dukoresha agakoresho ko gufunga icyuma kuva ku cyuma. Iyo intebe ya PPL ihiye mu gihe cy'inkongi y'umuriro, umuvuduko w'umurongo utera umupira kuri uyu munwa w'icyuma kugira ngo ugabanye amazi ava hasi.

7. Urutonde rw'intambwe 4 zo gushaka amasoko mu Bushinwa

Iyo ushaka valves zishyushye cyane kuriUruganda rukora valve z'umupira mu Bushinwa, menya neza ko itsinda ryawe rya QA rigenzura ibi bipimo ngenderwaho:

+- ...

Intambwe ya 1 - Gukurikirana ibikoresho– Raporo z’ibizamini by’inganda zikozwe mu buryo bw’umwimerere (ASTM A216 WCB cyangwa A351 CF8M) zifite imibare y’ubushyuhe ku mubiri (ASTM A216 WCB cyangwa A351 CF8M).

Intambwe ya 2 - Isuzuma ry'ubushyuhe bwinshi– Ibizamini bisanzwe by’amazi bishobora kudagaragaza imiterere y’intebe kuri 250°C. Saba ibizamini by’ibyuka bishyushye cyangwa ubushyuhe ku matsinda y’ingero.

Intambwe ya 3 - Ubukomere bwo gusiga– Ku ntebe z'icyuma, inyandiko z'ubukana bwa HVOF zigomba kugaragaza HRC ≥68‑70 kugira ngo zidaterwa n'agahinda cyangwa amanota.

Intambwe ya 4 - Kohereza ibipfunyika mu mahanga– Amasanduku akomeye ya plywood afite ifuro ryihariye kugira ngo hirindwe ko ibiti bigonga mu gihe cyo gutwara ibintu mu mazi.
