Ibibazo birindwi byerekeranye na valve

Iyo ukoresheje valve, hari ibibazo bimwe bibabaza, harimo na valve idafunzwe inzira yose. Nkore iki? Igenzura rya valve rifite ibintu bitandukanye byimbere biva imbere kubera ubwoko bwa valve yuburyo bugoye. Uyu munsi, tuzaganira kuburyo burindwi butandukanye bwimbere yo kugenzura valve imbere no gusesengura no gukosora kuri buri.

1. Umuyoboro ntiwigeze ufunga ku buryo bwuzuye kandi imiterere ya zeru ya zeru ntabwo ari yo.

Igisubizo:

1) Intoki funga valve (byukuri ko ifunze burundu);

2) Fungura valve intoki, mugihe imbaraga nke zidashobora gukoreshwa kugirango zihindurwe;

3) Hindura valve igice cyerekezo mucyerekezo gitandukanye;

4) Ibikurikira, hindura imipaka yo hejuru.

2. Intego ya Acuator ntabwo ihagije.

Imikorere ya actuator ntabwo ihagije kuko valve iri murwego rwo gusunika hasi. Iyo nta gitutu kirimo, biroroshye kugera kumwanya ufunze byuzuye, ariko mugihe hari igitutu, kuzamuka kwamazi ntigushobora guhangana, bigatuma bidashoboka gufunga burundu.

Igisubizo: gusimbuza ibintu byinshi-bitera imbaraga, cyangwa uhindure ibintu byuzuye kugirango ugabanye imbaraga zidahwitse ziciriritse

3. Kumeneka imbere kuzanwa nubwubatsi bubi bwo kugenzura amashanyarazi

Kuberako abakora valve batagenzura cyane ibikoresho bya valve, tekinoroji yo gutunganya, ikoranabuhanga ryo guteranya, nibindi mugihe cyibikorwa, umusaruro wo gufunga ntabwo uri hasi kurwego rwo hejuru kandi inenge nka pitingi na trachoma ntizikurwaho burundu, biganisha kumeneka imbere amashanyarazi yo kugenzura amashanyarazi.

Igisubizo: Ongera usubire hejuru

4. Igice cyo kugenzura amashanyarazi agenzura igice kigira ingaruka kumyuka yimbere.

Uburyo bwo kugenzura imashini, harimo guhinduranya imipaka ya valve no hejuru ya torque, nuburyo gakondo bwo gukoresha amashanyarazi agenzura amashanyarazi. Ikibanza cya valve ntigisobanutse neza, amasoko yarashaje, kandi coefficent yo kwaguka yubushyuhe ntago ihwanye kuko ibyo bikoresho bigenzurwa nubushyuhe bukikije, umuvuduko, nubushuhe. nibindi bihe byo hanze, aribyo nyirabayazana yo kugenzura amashanyarazi imbere.

Igisubizo: hindura imipaka.

5. Kumeneka imbere byazanywe nibibazo hamwe no gukemura ibibazo bya mashanyarazi

Birasanzwe ko amashanyarazi agenzura kunanirwa gufungura nyuma yo gufungwa nintoki, biterwa no gutunganya no guteranya. Umwanya wibikorwa byo hejuru no hepfo ntarengwa byahinduwe birashobora gukoreshwa muguhindura inkoni yumuriro wamashanyarazi. Niba inkorora ihinduwe ntoya, igenzura ry'amashanyarazi ntirizifunga cyane cyangwa ngo rifungure; niba inkorora ihinduwe nini, bizatera birenze urugero uburyo bwo kurinda torque;

Niba ibikorwa bya over-torque byahinduwe byongerewe agaciro, hazabaho impanuka ishobora kwangiza valve cyangwa uburyo bwo kugabanya kugabanuka, cyangwa no gutwika moteri. Mubisanzwe, nyuma yo gucana amashanyarazi yagenzuwe, umwanya wo hasi wumwanya wumuryango wamashanyarazi ushyirwaho nintoki uzunguza intoki igenzura amashanyarazi munsi, hanyuma ukayizunguza mu cyerekezo cyo gufungura, kandi umupaka wo hejuru ugashyirwaho nintoki. kunyeganyeza amashanyarazi agenzura imyanya ifunguye neza.

Kubwibyo, amashanyarazi agenzura amashanyarazi ntazabuzwa gukingurwa nyuma yo gufungwa cyane n'intoki, kwemerera urugi rw'amashanyarazi gukingura no gufunga mu bwisanzure, ariko bizavamo cyane cyane kumeneka imbere yumuryango wamashanyarazi. Nubwo amashanyarazi agenzura amashanyarazi yashyizweho neza, kubera ko aho ibikorwa bigarukira bigarukira cyane cyane, uburyo bugenzura buzakomeza gukaraba no kwambara valve mugihe ikoreshwa, ibyo bikazavamo no kumeneka kwimbere kuva gufunga kwa valve.

Igisubizo: hindura imipaka.

6.

Cavitation hamwe nigitutu gitandukanye birahujwe. Cavitation izabaho niba itandukaniro ryumuvuduko nyawo P ya valve irenze itandukaniro ryumuvuduko ukabije Pc kuri cavitation. Ingufu zingirakamaro zitangwa mugihe cya cavitation mugihe igituba giturika, kigira ingaruka kumyanya ya valve na core ya valve. Umuyoboro rusange ukorera mubihe byamezi atatu cyangwa arenga, bivuze ko valve irwaye kwangirika gukabije, bigatuma imyanya yintebe isohoka kugeza 30% byurugendo rwateganijwe. Ibice bya trottling bifite ingaruka zikomeye zo gusenya. Ibi byangiritse ntibishobora gukosorwa.

Kubwibyo, ibisabwa bya tekiniki byihariye kubikoresho byamashanyarazi biratandukanye bitewe nicyo bagenewe. Nibyingenzi guhitamo amashanyarazi agenzura ubwenge muburyo bwa sisitemu.

Igisubizo: Kugirango utezimbere inzira, hitamo ibyiciro byinshi kumanuka-hasi cyangwa amaboko agenga valve.

7. Kumeneka imbere bituruka ku kwangirika hagati no gusaza kwa valve igenzura amashanyarazi

Nyuma yo kugenzura amashanyarazi amaze guhindurwa, nyuma yimikorere runaka, valve igenzura amashanyarazi izafungwa kubera ko inkoni ari nini cyane bitewe na valve cavitating, kwangirika hagati, intangiriro ya valve nintebe bishaje, kandi gusaza kwibigize imbere. Ubwiyongere bw'amashanyarazi agenzura amashanyarazi yamenetse ni ibisubizo by'ubunebwe. Imiyoboro yo kugenzura amashanyarazi imbere izagenda iba mibi mugihe runaka.

Igisubizo: hindura imikorere hanyuma ukore buri gihe kubungabunga no guhitamo.
