Ukutshixa, ukuphawula kunye nokulawula amandla ayingozi kwindawo yokusebenzela

I-OSHA iyalela abasebenzi bolondolozo ukuba batshixe, bathege, balawule imithombo yamandla eyingozi.Abanye abantu abazi ukuba bathathe njani eli nyathelo, wonke umatshini wahlukile.Getty Imifanekiso

Phakathi kwabantu abasebenzisa naluphi na uhlobo lwezixhobo zoshishino,ukutshixa/i-tagout (LOTO)akukho nto intsha.Ngaphandle kokuba umbane ucinyiwe, akukho mntu unobuganga bokwenza naluphi na uhlobo logcino lwesiqhelo okanye ukuzama ukulungisa umatshini okanye inkqubo.Oku yimfuneko nje yengqiqo kunye noKhuseleko loMsebenzi kunye noLawulo lwezeMpilo (OSHA).

Ngaphambi kokwenza imisebenzi yokulungisa okanye ukulungiswa, kulula ukukhupha umatshini kumthombo wayo wamandla-ngokuqhelekileyo ngokucima i-breaker circuit-kunye nokutshixa umnyango wepaneli yesiphaluka.Ukongeza ileyibhile echaza amagama amagcisa olondolozo nako kuyinto elula.

Ukuba amandla akakwazi ukutshixwa, ileyibhile kuphela enokusetyenziswa.Kuzo zombini ezi meko, nokuba kutshixiwe okanye akukho, ileyibhile ibonisa ukuba ulungiso luyaqhubeka kwaye isixhobo asikho mbane.

Nangona kunjalo, oku ayisosiphelo selotho.Injongo iyonke ayikokuqhawula nje umthombo wamandla.Injongo kukusebenzisa okanye ukukhulula onke amandla anobungozi-kwimigaqo ye-OSHA, ukulawula amandla ayingozi.

Isarha eqhelekileyo ibonisa iingozi ezimbini zokwexeshana.Emva kokuba i-saw ivaliwe, i-saw blade iya kuqhubeka iqhuba imizuzwana embalwa, kwaye iya kumisa kuphela xa umfutho ogcinwe kwi-motor uphelile.I-blade iya kuhlala ishushu imizuzu embalwa de ubushushu buphele.

Kanye nje ngokuba iisarha zigcina oomatshini kunye namandla ashushu, umsebenzi wokuqhuba oomatshini bemizi-mveliso (umbane, ihydraulic kunye ne-pneumatic) unokugcina amandla ixesha elide.​ Ngokuxhomekeke kubuchule bokutywina be-hydraulic okanye ipneumatic system, okanye amandla ombane. isekethe, amandla anokugcinwa ixesha elide emangalisayo.

Oomatshini abahlukeneyo bemizi-mveliso kufuneka basebenzise amandla amaninzi.Intsimbi eqhelekileyo i-AISI 1010 inokumelana namandla okugoba ukuya kuthi ga kwi-45,000 ye-PSI, ngoko ke oomatshini abafana neziqhoboshi zokucinezela, iipuntshi, iipuntshi, kunye nee-benders zemibhobho kufuneka bathumele amandla kwiiyunithi zeetoni.Ukuba i-circuit powering system ye-hydraulic pump ivaliwe kwaye inqanyuliwe, inxalenye ye-hydraulic yenkqubo isenokukwazi ukubonelela nge-45,000 PSI.Koomatshini abasebenzisa imingundo okanye iincakuba, oku kwanele ukutyumza okanye ukuqhawula amalungu omzimba.

Ilori yebhakethi evaliweyo ene-emele emoyeni iyingozi kanye njengelori yebhakethi engavalwanga.Vula ivalve engalunganga kwaye ubunzima buzakuthatha indawo.Ngokufanayo, inkqubo ye-pneumatic inokugcina amandla amaninzi xa icinyiwe.I-bender yombhobho yobungakanani obuphakathi inokufunxa ukuya kuthi ga kwi-150 amperes yangoku.Ngaphantsi kwe-0.040 amps, intliziyo inokuyeka ukubetha.

Ukukhulula ngokukhuselekileyo okanye ukunciphisa amandla kuyinyathelo eliphambili emva kokucima amandla kunye neLOTO.Ukukhutshwa okukhuselekileyo okanye ukusetyenziswa kwamandla anobungozi kufuna ukuqonda imigaqo yenkqubo kunye neenkcukacha zomshini omele ugcinwe okanye ulungiswe.

Kukho iintlobo ezimbini zeenkqubo zoxinzelelo lwe-hydraulic: i-loop evulekile kunye ne-loop evaliweyo.Kwimeko yeshishini, iintlobo zempompo eziqhelekileyo ziigiya, i-vanes, kunye neepiston.I-cylinder yesixhobo esisebenzayo sinokuba yinto enye okanye iphindwe kabini.Iinkqubo zeHydraulic zinokuba naziphi na iintlobo ezintathu zevalve-indlela yokulawula, ulawulo lokuhamba, kunye nolawulo loxinzelelo-nganye kwezi ntlobo zineentlobo ezininzi.Kukho izinto ezininzi ekufuneka ziqwalaselwe, ngoko ke kuyimfuneko ukuqonda ngokupheleleyo uhlobo lwecandelo ngalinye ukuphelisa iingozi ezinxulumene namandla.

UJay Robinson, umnini kunye nomongameli weRbSA Industrial, uthe: "Isixhobo sokwenza amanzi amdaka sinokuqhutywa sisivalo esivalayo esigcweleyo."“Ivalve yesolenoid ivula ivalve.Xa inkqubo isebenza, i-hydraulic fluid igeleza kwisixhobo ngoxinzelelo oluphezulu kunye netanki ngoxinzelelo oluphantsi, "utshilo.."Ukuba inkqubo ivelisa i-2,000 PSI kwaye umbane ucinyiwe, i-solenoid iya kwindawo ephakathi kwaye ivimbele onke amachweba.Ioyile ayinakuhamba kwaye umatshini uyayeka, kodwa inkqubo inokuba ne-PSI efikelela kwi-1,000 kwicala ngalinye levalvu.
