Gufunga, gushushanya no kugenzura ingufu ziteje akaga mumahugurwa

OSHA itegeka abakozi bashinzwe gufunga, kuranga, no kugenzura inkomoko yingufu.Abantu bamwe ntibazi gutera iyi ntambwe, buri mashini iratandukanye.Amashusho

Mu bantu bakoresha ibikoresho byose byinganda,gufunga / tagout (LOTO)nta gishya.Keretse niba imbaraga zaciwe, ntamuntu numwe watinyuka gukora uburyo ubwo aribwo bwose bwo kubungabunga cyangwa kugerageza gusana imashini cyangwa sisitemu.Ibi nibisabwa gusa mubwenge busanzwe hamwe nubuyobozi bushinzwe umutekano nubuzima (OSHA).

Mbere yo gukora imirimo yo kubungabunga cyangwa gusana, biroroshye guhagarika imashini nisoko yimbaraga zayo-mubisanzwe uzimya icyuma cyumuzunguruko-hanyuma ugafunga umuryango wikibaho.Ongeraho ikirango kigaragaza abatekinisiye kubungabunga izina nabwo ni ibintu byoroshye.

Niba imbaraga zidashobora gufungwa, ikirango cyonyine gishobora gukoreshwa.Muri ibyo aribyo byose, haba hamwe cyangwa udafunze, ikirango cyerekana ko kubungabunga biri gukorwa kandi igikoresho ntigikoreshwa.

Ariko, iyi ntabwo iherezo rya tombora.Intego rusange ntabwo ari uguhagarika inkomoko yimbaraga.Intego ni ugukoresha cyangwa kurekura ingufu zose zangiza-mumagambo ya OSHA, kugenzura ingufu zangiza.

Igiti gisanzwe cyerekana akaga kabiri.Nyuma yo kuzimya, icyuma kizakomeza gukora amasegonda make, kandi kizahagarara gusa igihe imbaraga zibitswe muri moteri zashize.Icyuma kizakomeza gushyuha muminota mike kugeza ubushyuhe bugabanutse.

Nkuko ibiti bibika ingufu za mashini nubushyuhe, umurimo wimashini zikoresha inganda (amashanyarazi, hydraulic na pneumatike) zishobora kubika ingufu igihe kirekire. Ukurikije ubushobozi bwo gufunga sisitemu ya hydraulic cyangwa pneumatike, cyangwa ubushobozi bwa umuzunguruko, ingufu zirashobora kubikwa igihe kirekire gitangaje.

Imashini zitandukanye zinganda zikeneye gukoresha ingufu nyinshi.Ibyuma bisanzwe AISI 1010 birashobora kwihanganira imbaraga zigoramye zigera kuri 45.000 PSI, bityo imashini nka feri yo gukanda, gukubita, gukubita, no guhuza imiyoboro igomba kohereza imbaraga mubice bya toni.Niba umuzunguruko ukoresha sisitemu ya hydraulic pompe yafunzwe kandi ugahagarikwa, igice cya hydraulic ya sisitemu kirashobora gutanga 45,000 PSI.Kumashini zikoresha ibishushanyo cyangwa ibyuma, ibi birahagije kumenagura cyangwa gutema ingingo.

Ikamyo y'indobo ifunze ifite indobo mu kirere ni mbi cyane nk'ikamyo y'indobo idafunze.Fungura valve itariyo kandi uburemere bizatwara.Mu buryo nk'ubwo, sisitemu ya pneumatike irashobora kugumana imbaraga nyinshi mugihe yazimye.Umuyoboro uringaniye uringaniye urashobora gukuramo amperes zigera kuri 150 zubu.Hafi ya 0.040 amps, umutima urashobora guhagarika gutera.

Kurekura neza cyangwa kugabanya ingufu nintambwe yingenzi nyuma yo kuzimya amashanyarazi na LOTO.Kurekura neza cyangwa gukoresha ingufu zangiza bisaba gusobanukirwa amahame ya sisitemu nibisobanuro byimashini igomba kubungabungwa cyangwa gusanwa.

Hariho ubwoko bubiri bwa sisitemu ya hydraulic: gufungura no gufunga.Mu nganda zikora inganda, ubwoko bwa pompe busanzwe ni ibikoresho, ibinyabiziga, na piston.Silinderi yigikoresho gikora irashobora kuba imwe-ikora cyangwa ikora kabiri.Sisitemu ya Hydraulic irashobora kugira ubwoko bumwe muburyo butatu bwa valve-kugenzura icyerekezo, kugenzura imigezi, no kugenzura umuvuduko-buri bwoko bufite ubwoko bwinshi.Hariho ibintu byinshi ugomba kwitondera, birakenewe rero gusobanukirwa neza buri bwoko bwibigize kugirango ukureho ingaruka ziterwa ningufu.

Jay Robinson, nyiri akaba na perezida w’inganda za RbSA, yagize ati: “Imashini ikora hydraulic irashobora gutwarwa n’icyambu cyose gifunga icyambu.”“Umuyoboro wa solenoid ufungura valve.Iyo sisitemu ikora, amazi ya hydraulic atembera mu bikoresho ku muvuduko mwinshi ndetse no kuri tank ku muvuduko muke ”..Ati: "Niba sisitemu itanga PSI 2000 kandi amashanyarazi akazimya, solenoid izajya mumwanya wo hagati kandi ihagarike ibyambu byose.Amavuta ntashobora gutemba kandi imashini irahagarara, ariko sisitemu irashobora kugira PSI igera ku 1.000 kuri buri ruhande rwa valve. ”
