Kumenyekanisha amashanyarazi kumashanyarazi (II)

Kumenyekanisha amashanyarazi kumashanyarazi (II) Igikoresho gishobora kugenzura imigendekere yamazi mumuyoboro uhindura igice cyumuyoboro witwa valve cyangwa igice cya valve. Uruhare rwibanze rwa valve mumuyoboro ni: uhujwe cyangwa uciwe; Irinde gusubira inyuma kw'itangazamakuru; Hindura igitutu, imigendekere nibindi bipimo byo hagati; Gutandukanya, kuvanga, cyangwa gukwirakwiza itangazamakuru; Irinde umuvuduko wo hagati urenze agaciro kagenwe, kugirango ukomeze umuhanda cyangwa kontineri, umutekano wibikoresho. Igikoresho gishobora kugenzura imigendekere yamazi mumuyoboro uhindura igice cyumuyoboro witwa valve cyangwa igice cya valve. Uruhare rwibanze rwa valve mumuyoboro ni: uhujwe cyangwa uciwe; Irinde gusubira inyuma kw'itangazamakuru; Hindura igitutu, imigendekere nibindi bipimo byo hagati; Gutandukanya, kuvanga, cyangwa gukwirakwiza itangazamakuru; Irinde umuvuduko wo hagati urenze agaciro kagenwe, kugirango ukomeze umuhanda cyangwa kontineri, umutekano wibikoresho. Hamwe niterambere ryubumenyi nubuhanga bugezweho, valve mubikorwa byinganda, ubwubatsi, ubuhinzi, kurengera igihugu, ubushakashatsi bwa siyansi nubuzima bwabantu hamwe nubundi buryo bwo gukoresha bugenda buba rusange, byahindutse ibikoresho rusange byubukanishi mubikorwa bitandukanye byabantu. Indangagaciro zikoreshwa cyane mubuhanga bwo gukora imiyoboro. Hariho ubwoko bwinshi bwa valve kubintu bitandukanye. Cyane cyane mumyaka yashize, ibyubatswe bishya, ibikoresho bishya hamwe nuburyo bushya bwo gukoresha indangagaciro. Kugirango duhuze ibipimo ngenderwaho, ariko kandi muguhitamo neza no kumenya neza valve, murwego rwo koroshya umusaruro, kwishyiriraho no gusimbuza, ibisobanuro bya valve nibisanzwe, rusange, iterambere ryicyerekezo. Gutondekanya indangagaciro: Umuyoboro w’inganda wavutse nyuma yo kuvumburwa na moteri y’amazi, mu myaka makumyabiri cyangwa mirongo itatu ishize, kubera peteroli, imiti, sitasiyo y’amashanyarazi, zahabu, amato, ingufu za kirimbuzi, ikirere n’ibindi bikenerwa, bishyirwa imbere ibisabwa cyane kuri valve, kugirango abantu bashake kandi batange ibipimo bihanitse bya valve, ubushyuhe bwakazi bwayo kuva ubushyuhe bwa mbere -269 ℃ kugeza 1200 ℃, ndetse kugeza kuri 3430 ℃; Umuvuduko wakazi kuva ultra-vacuum 1.33 × 10-8Pa (1 × 1010mmHg) kugeza kuri ultra-high pressure 1460MPa; Ingano ya Valve iri hagati ya 1mm kugeza 6000mm na kugeza kuri 9750mm. Valve ibikoresho biva mubyuma, ibyuma bya karubone, iterambere kugeza titanium na titanium alloy ibyuma, hamwe nicyuma cyangirika cyane, ibyuma byubushyuhe buke hamwe nicyuma cyangiza ubushyuhe. Uburyo bwo gutwara valve kuva iterambere ryiterambere kugeza amashanyarazi, pneumatike, hydraulic, kugeza gahunda igenzura, ikirere, kugenzura kure, nibindi .. Tekinoroji yo gutunganya ibicuruzwa biva mubikoresho bisanzwe byimashini kugeza kumurongo, umurongo wikora. Ukurikije uruhare rwo gufungura no gufunga valve, uburyo bwo gutondekanya valve nibyinshi, hano kugirango tumenye byinshi bikurikira. 1. Gutondekanya kumikorere no gukoresha (1) guhagarika valve: guhagarika valve nayo izwi nka valve ifunze, uruhare rwayo ni uguhuza cyangwa guca imiyoboro mumiyoboro. Ibice byaciwemo birimo amarembo, amarembo yisi, imashini icomeka, imipira yumupira, ibinyugunyugu na diaphragm. . Kuvoma pompe yamazi kumurongo wo hasi nabyo ni ibya cheque. . . . 2. Gutondekanya kumuvuduko wizina (1) Umuyoboro wa Vacuum: bivuga valve ifite umuvuduko wakazi uri munsi yumuvuduko ukabije wikirere. (2) umuvuduko muke wa valve: bivuga igitutu nominal PN≤ 1.6mpa valve. . (4) Umuvuduko mwinshi wumuvuduko: bivuga kuri valve ifite umuvuduko PN ni 10 ~ 80Mpa. (5) Ultra-high pressure valve: bivuga valve ifite umuvuduko wizina PN≥100Mpa. 3. Gutondekanya ubushyuhe bwo gukora (1) ** ubushyuhe bwubushyuhe: bukoreshwa mubushyuhe bwo hagati bwo gukora T-100 ℃ valve. (2) ubushyuhe buke: ikoreshwa mubushyuhe bwo hagati -100 ℃ ≤ T ≤-40 ℃ valve. . . 4. Gutondekanya muburyo bwo gutwara (1) Automatic valve bivuga valve idakenera imbaraga ziva hanze kugirango itware, ariko yishingikiriza ku mbaraga zo hagati ubwayo kugirango ikore valve. Nka valve yumutekano, umuvuduko ugabanya valve, umutego, kugenzura valve, kugenzura byikora byikora nibindi. . Umuyoboro w'amashanyarazi: Valve itwarwa n'amashanyarazi. Umuyoboro wa pneumatike: valve itwarwa numwuka uhumeka. Hydraulic valve: Valve itwarwa numuvuduko wamazi nkamavuta. Mubyongeyeho, hariho uburyo bwinshi bwo gutwara hejuru, nka gaze-amashanyarazi. . Iyo valve ifungura no gufunga torque nini, kugabanya uruziga cyangwa kugabanya ibikoresho byinyo birashobora gushirwa hagati yiziga ryintoki nigiti cya valve. Nibiba ngombwa, guhuriza hamwe kwisi yose hamwe no gutwara ibinyabiziga nabyo birashobora gukoreshwa mubikorwa bya kure. Muncamake, uburyo bwo gutondekanya valve nibyinshi, ariko cyane cyane ukurikije uruhare rwayo mubyiciro. Indangantego rusange mubikorwa byinganda nubwubatsi birashobora kugabanywamo ibyiciro 11, aribyo valenti y irembo, globe yisi, plug valve, umupira wumupira, ikinyugunyugu, diaphragm valve, cheque valve, trottle valve, valve yumutekano, umuvuduko ugabanya valve na trap valve. Ibindi byuma bidasanzwe, nkibikoresho byabigenewe, imiyoboro ya hydraulic igenzura imiyoboro ya sisitemu, indangagaciro zikoreshwa mu mashini n’ibikoresho bitandukanye bya shimi, ntabwo biri muri iki gitabo (2) Iyo moteri ikora amashanyarazi igizwe numwanya wumurima werekana uburyo, icyerekezo cya uburyo bwo kwerekana bugomba kuba bujyanye nicyerekezo cyo guhinduranya icyerekezo gisohoka, kandi nta guhagarara cyangwa hystereze ikora. Kuzenguruka Inguni igomba kuba 80 ° ~ 280 ° mugihe amashanyarazi akozwe hamwe na transmitter. Umuvuduko w'amashanyarazi ugomba kuba DC 12V ~ -30V, naho ibimenyetso byerekana ibisohoka bigomba kuba (4 ~ 20) mADC, kandi ikosa ryo kwimurwa nyirizina ryibisohoka byanyuma byamashanyarazi ntibigomba kurenza 1% y'urwego rw'agaciro k'ibisohoka byerekana ibimenyetso Guhuza: Intangiriro kumashanyarazi akoresha amashanyarazi ya sitasiyo (I) 5.10. Iyo amashanyarazi afite ibikoresho byumurima byerekana uburyo, icyerekezo cyerekana uburyo bugomba kuba buhuye nicyerekezo cyo guhinduranya icyerekezo cyo gusohora ibisohoka, kandi nta guhagarara cyangwa hystereze ikora. Inguni izunguruka igomba kuba 80 ° ~ 280 ° 5.2.11 mugihe icyuma cyohereza imyanya cyashyizweho kugirango gikoreshe amashanyarazi, voltage yumuriro w'amashanyarazi igomba kuba 12V ~ -30V, naho ikimenyetso cyo gusohoka kizaba (4 ~ 20) mADC . birenga 75dB (A) urwego rwumuvuduko wijwi 5.2.13. Kurwanya insulasiyo hagati yibice byose bitwara amashanyarazi hamwe namazu ntibishobora kuba munsi ya 20M ω 5.2.14 Imashanyarazi irashobora kwihanganira inshuro ya 50Hz, voltage ni sinusoidal ihinduranya umuyaga uvugwa mumeza 2 , na test ya dielectric imara lmin. Mugihe cyikizamini, gusenyuka kwizuba, hejuru ya flashover, kwiyongera gukabije kwimyuka cyangwa kugabanuka gutunguranye kwa voltage ntibishobora kubaho. Imbonerahamwe 2 Umuvuduko wikizamini 5.2.15 Uburyo bwo guhinduranya intoki-amashanyarazi bigomba guhinduka kandi byizewe, kandi intoki ntizizunguruka mugihe cyo gukora amashanyarazi (usibye guterwa no guterana amagambo). 5.2.16 Umuyoboro munini wo kugenzura amashanyarazi ntushobora kuba munsi yumuriro wagenwe. ** Umucyo muto wo kugenzura ntushobora kuba hejuru yumuriro wagenwe, kandi ntushobora kurenza 50% byumubyigano munini ugereranije 5.2.17 Umuyoboro washyizweho ntushobora kuba hejuru yumuriro munini ugereranije kandi nturi munsi ya ntarengwa yo kugenzura. Niba umukoresha adasabye itara, ntarengwa yo kugenzura igomba gushyirwaho. 5.2.18 Umuriro wo guhagarika amashanyarazi akoresha inshuro 1.1 kurenza urumuri runini rwo kugenzura. 5.2.19 Igice cyo kugenzura amashanyarazi kigomba kuba cyoroshye kandi cyizewe, kandi gishobora guhindura ingano yumuriro wo kugenzura. Isubiramo ryukuri rya torque yo kugenzura igomba guhuza nibiteganijwe mu mbonerahamwe ya 3. Imbonerahamwe 3 Igenzura rya torque isubiramo neza 5.2.20. Uburyo bwo kugenzura inkoni yumuriro wamashanyarazi bugomba kuba bworoshye kandi bwizewe, kandi gutandukana kumwanya wogusubiramo kugiti gisohoka kigomba guhuza nibiteganijwe mumbonerahamwe 4, kandi hazashyirwaho ibimenyetso byo guhindura imyanya ya "kuri" na "kuzimya" . Imbonerahamwe 4 Gutandukana gusubiramo umwanya 5.2.21 mugihe amashanyarazi ahita yikorera umutwaro uvugwa mumbonerahamwe 5, ibice byose bitwara ntibishobora guhinduka cyangwa kwangirika. 5.2.22. 5 5.3.2 amashanyarazi akoresha igice cyo kugenzura ingufu agomba kuba yujuje ibyangombwa bya tekiniki muri 5.2. 5.3.3 Ikosa ryibanze ryumuyagankuba ntirishobora kurenga 1.0% 5.3.4 Ikosa ryo kugaruka kumashanyarazi ntirishobora kurenga 1.0%
