Aho gushyiramo nta mwanya wo gukoreraho

Ingamba: Nubwo gushyiraho byagorana mu ntangiriro, ni ngombwa kwita ku kazi k'igihe kirekire k'umukoresha mu gihe cyo gushyiravalvekugira ngo bikoreshwe. Kugira ngo habeho gufungura no gufungavalveBiroroshye, ni byiza gushyira urukiramende rw'intoki rwa valve ku buryo rugera ku gituza (ubusanzwe metero 1.2 uvuye hasi mu cyumba cyo kubaga). Kugira ngo hirindwe imikorere mibi, urukiramende rw'intoki rwa valve yo kugwaho rugomba kwerekeza hejuru ntirube rurerure. Valve zo ku rukuta rw'imashini n'ibindi bice byayo bigomba gutanga umwanya uhagije kugira ngo uyikoresha ashobore guhagarara. Ni bibi cyane gukorera mu kirere, cyane cyane iyo ukoresha aside-base, ibintu biteje akaga, nibindi.

Valve zikozwe mu bikoresho bicika intege

Ingamba: Mu gihe ushyiraho n'ubaka, witondere kandi wirinde gukubita valves z'ibikoresho bicika intege. Reba valve, imiterere, n'ingero mbere yo kuyishyiraho, kandi urebe niba hari icyangiritse, cyane cyane ku gice cy'imashini. Igice cy'imashini gishobora kuba kigoramye mu gihe cyo kohereza, bityo uhindure inshuro nke kugira ngo urebe niba ari cyo. Sukura valves n'imyanda iyo ari yo yose. Kugira ngo wirinde kwangiza uruziga rw'intoki cyangwa igice cy'imashini iyo uzamuye valve, umugozi ugomba gushyirwa ku gipfunyika aho kuba kuri kimwe muri ibi bice. Imiyoboro ya valve igomba gusukurwa. Kugira ngo ukureho uduce twa oxide y'icyuma, umusenyi w'ibitaka, slag yo gusudira, n'ibindi bikoresho, koresha umwuka ufunze. Uduce duto tw'imashini, nk'islag yo gusudira, dushobora kubuza valves nto gukora kandi bigatuma zidakora hamwe no gukurura ubuso bwo gufunga valve byoroshye. Kugira ngo hirindwe ko valve yiyongera mu gice cy'imashini no kubangamira inzira y'imashini, agapfunyika ko gufunga (line hemp plus lead oil cyangwa PTFE raw material tape) kagomba kuzunguruka ku mugozi w'umuyoboro mbere yo gushyiraho valve yo gusudira. Menya neza ko uhambiriye amaboliti neza kandi mu buryo bungana mu gihe ushyiraho amavali afite imigozi. Kugira ngo wirinde ko vali yatera umuvuduko mwinshi cyangwa ngo ivunike, umugozi n'umugozi bifite imigozi bigomba kuba bingana kandi bifite aho bibohokera hakwiye. Ibikoresho bitoroshye na vali zikomeye nkeya bisaba kwitabwaho cyane. Vali zikozwe mu migozi zigomba kuba zikozwe mu buryo butaziguye mbere, hagakurikiraho gufungura burundu ibice bifunga, hanyuma hagakurikiraho gusudira bipfuye.

Valve nta buryo bwo kubika ubushyuhe cyangwa uburyo bwo kubika ubukonje ifite

Ingamba: Hari kandi n'ibikoresho bimwe na bimwe byo kurinda ubushyuhe n'ubukonje. Hari igihe umuyoboro w'umwuka ushyushye wongerwa ku gice cyo gukingira. Ubwoko bw'icyuma gikwiye kuguma gishyushye cyangwa gikonje biterwa n'ibyo uruganda rusaba. Mu by'ukuri, kubungabunga ubushyuhe cyangwa gukurikirana ubushyuhe birakenewe niba igice kiri imbere muri icyuma gikonje cyane, bikagabanya umusaruro cyangwa bigatuma icyuma gikonjesha. Mu buryo nk'ubwo, iyo icyuma gishyizwe ahagaragara, ibyo bikaba ari bibi ku musaruro cyangwa bigatera ubukonje n'ibindi bintu bidakenewe, icyuma gikwiye kuguma gikonjesha. Ibikoresho byo gukingira ubukonje birimo cork, perlite, foam, pulasitiki, diatomaceous earth, asbestos, slag wool, ikirahure wool, perlite, diatomaceous earth, nibindi.

Umutego w'umwuka ntabwo washyizweho ku ruhande

Ibipimo: Hari valve zimwe na zimwe zifite ibikoresho n'ibice by'ingenzi byo kurinda. Kugira ngo habeho uburyo bworoshye bwo kubungabunga umutego, hashyizweho valve yo kunyura mu nzira. Hari valve nyinshi zishyirwa hamwe na bypass. Imiterere, akamaro, n'ibisabwa mu gukora valve ni byo bigaragaza niba bypass igomba gushyirwaho.

Gupakira ntibisimburwa buri gihe

Ibipimo: Hari udupaki tw’udupaki turi mu bubiko tugomba gusimburwa kuko tudakora neza cyangwa tudahuye n’uburyo bukoreshwa. Agasanduku ko gushyiramo ibintu gahora kuzuyemo udupaki dusanzwe kandi agapaki kagaragara ku bihumbi by’ibintu bitandukanye, ariko iyo agapaki kari gukora, agapaki kagomba guhindurwa kugira ngo gakoreshwe mu buryo bujyanye n’uburyo. Kanda agapaki aho ushyira mu mwanya wako uzenguruka mu ruziga. Umugozi wa buri ruziga ugomba kuba dogere 45, kandi imigozi y’udupaki igomba kuba dogere 180 hagati y’udupaki. Igice cyo hasi cy’agapaki kigomba gukandagirwa kugeza ku bujyakuzimu bukwiye bw’agapaki, ubusanzwe ari 10-20% by’ubujyakuzimu bwose bw’agapaki. Uburebure bw’agapaki bugomba kuzirikana ibi. Inguni y’umugozi w’udupaki ifite ibipimo bikomeye ni dogere 30. Imigozi y’uruziga itandukanye kuri dogere 120 hagati y’undi. Impeta eshatu za O-rubber (rubber karemano irwanya alkali idakomeye iri munsi ya dogere selisiyusi 60, rubber ya nitrile irwanya amavuta iri munsi ya dogere selisiyusi 80, na rubber ya fluorine irwanya ibintu bitandukanye byangiza biri munsi ya dogere selisiyusi 150) nazo zishobora gukoreshwa, bitewe n'imimerere, hiyongereyeho ibyo byuzuza byavuzwe haruguru. Impeta za nylon (zirwanya ammonia na alkali iri munsi ya dogere selisiyusi 120), impeta za polytetrafluoroethylene za laminated (zirwanya ibintu bikomeye byangiza biri munsi ya dogere selisiyusi 200), n'izindi nyunganiramirire zifite ishusho. Zingira urwego rwa kaseti ya polytetrafluoroethylene idakomeye hanze y'ipaki isanzwe ya asbestos kugira ngo wongere kuziba no kugabanya kwangirika kw'umugongo wa valve bitewe n'imikorere ya electrochemical. Kugira ngo agace gakomeze kuba heza kandi kagame cyane, zunguza umugongo wa valve mugihe ukandagira ipaki. Ntugahindukire mugihe ukomeje gukaza gland ukoresheje imbaraga nyinshi.
