PC Emergency Stop Button (feem ntau hu ua Emergency Stop Button hauv cov khoom siv; txawm hais tias nws lub npe suav nrog "PC," nws cov haujlwm tseem ceeb yog tib yam li cov khoom siv thaum muaj xwm txheej ceev) Xauv mechanisms feem ntau yog siv rau siab - kev pheej hmoo ua haujlwm lossis kev lag luam uas yuav tsum tau muaj ntau txheej tiv thaiv. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv kev teeb tsa tsis raug los ntawm kev kaw lub cev, ua kom lub cuab yeej nyob twj ywm kom txog thaum muaj kev phom sij raug tshem tawm. Cov hauv qab no yog cov xwm txheej ntawm daim ntawv thov thiab cov hauv paus txheej txheem:
I. Tej yam kev thov kev thov
Automated ntau lawm kab
Scene: Multi-axis neeg hlau kev sib koom tes, siab- ceev conveyor siv, sib dhos kab, thiab lwm yam.
Yuav tsum tau: Thaum ib tug neeg raug ntes nyob rau hauv ib tug neeg hlau caj npab, cov khoom yog jammed los yog cov khoom siv overloaded, lub khawm nres thaum muaj xwm ceev yuav tsum tau muab xauv tom qab lub trigger los tiv thaiv tus neeg teb xov tooj los ntawm yuam kev reset ua ntej qhov teeb meem yuav daws tau, ua rau lwm yam kev raug mob.
Piv txwv li, nyob rau hauv lub tsheb vuam kab, yog hais tias tus neeg hlau txoj kev trajectory tsis zoo li qub, xauv lub khawm thaum muaj xwm ceev nres kom paub meej tias tag nrho cov cav yuav raug kaw kom txog rau thaum lub vuam fixture yog manually xyuas kom looseness.
Heavy Machinery ua haujlwm
Scene: xuas nrig ntaus, txhaj tshuaj molding tshuab, forging khoom, thiab lwm yam.
Yam yuav tsum tau muaj: Cov cuab yeej siv no muaj siab inertia thiab yuav tsum tau kaw tom qab kaw thaum muaj xwm txheej ceev los tiv thaiv cov khoom siv hluav taws xob los ntawm kev txav mus los sai sai vim yog rov pib dua sai.
Kev tuav pov hwm cov khoom siv phom sij
Scene: Cov tshuaj tiv thaiv hluav taws xob, cov khoom siv plua plav, qhov cub kub kub, thiab lwm yam.
Yuav Tsum Tau: Nyob rau hauv cov xwm txheej ntawm cov pa xau los yog kub dhau, qhov xwm txheej ceev ceev khawm kaw kom ntseeg tau tias lub zog (xws li chav lossis hluav taws xob) txuas ntxiv mus txog thaum pab pawg kev nyab xeeb txiav txim siab tias qhov kev pheej hmoo raug tshem tawm.
Txheem: NFPA 79 (tus qauv hluav taws xob) xav kom lub chaw nres tsheb xwm txheej ceev ntawm cov khoom siv no yuav tsum yog tus kheej - kaw thiab qhov kev cuam tshuam ntawm phau ntawv yuav tsum tau rov pib dua.
Rail Transit thiab elevator
Scene: subway qhov rooj, escalators, elevator.
Yuav Tsum Tau: Thaum muaj xwm ceev nres khawm xauv qhov rooj tiv thaiv lub qhov rooj / cov kauj ruam los ntawm kev yuam kev rov pib dua thaum cov neeg caij tsheb raug daig lossis cov khoom siv tsis raug. Piv txwv li, tom qab lub escalator thaum muaj xwm ceev nres, tsav lub cev muaj zog yuav tsum tau muab xauv kom txog thaum tus kws kho yuav manually reset nws.
Standard: EU EN 81-20/50 of elevator kev nyab xeeb Standard qhia meej meej yuav tsum muaj thaum muaj xwm ceev braking kom muaj ib tug xauv muaj nuj nqi.
II. Cov ntsiab cai rau kev siv technology
Mechanical Locking Structure: khawm nres thaum muaj xwm ceev txais tus kheej - txhawb kev tsim. Tom qab nias lub pob, qhov kev sib cuag raug kaw los ntawm lub kauj lossis lub tshuab slider, thiab tseem qhib txawm tias tom qab lub khawm tso tawm. Rov pib dua yuav tsum tig lossis nias lub pob (feem ntau yog 45-90℃kev sib hloov) txhawm rau tiv thaiv kev ua kom yuam kev.
Kev tsim hluav taws xob tsim hluav taws xob: Cov nyees khawm nres thaum muaj xwm ceev feem ntau muaj kev tiv thaiv los ntawm ob qhov ib txwm kaw (2NC) kev sib cuag hauv cov kab hauv kev nyab xeeb. Yog tias ib qho kev sib cuag tau daig, lub cuab yeej tseem yuav tsis pib.
Cov ntaub ntawv: Kev nyab xeeb relays lossis kev nyab xeeb PLCs saib xyuas cov xwm txheej nrog lub sijhawm teb Tsawg dua lossis sib npaug li 20ms kom ntseeg tau tias lub ntsiab tiv thaiv hluav taws xob tsis pub dhau 100ms (saib IEC 60204-1 tus qauv).
Ergonomic Requirements:
Cov khawm qhov siab yuav tsum nyob nruab nrab ntawm 0.6 thiab 1.7 meters thiab qhib kom ntseeg tau tias muaj kev kub ntxhov ceev.
Xim thiab cim: liab nceb -zoo li tus khawm, lub hauv paus daj, ISO 13850 ua raws, siab pom, yooj yim txheeb xyuas.
III. Kev Ua Raws Cai
Cov qauv ntawv pov thawj: Cov khoom siv yuav tsum tau ua raws li cov qauv xws li CE (EU), UL (North America), CCC (Tuam Tshoj), thiab cov khawm nres thaum muaj xwm ceev yuav tsum ua raws li cov qauv xws li IEC 60947-5-5 thiab ISO 13850. Kev soj ntsuam kev pheej hmoo: Raws li ISO 12100 cov qauv, cov lag luam yuav tsum tau ua qhov kev ntsuam xyuas kev pheej hmoo ntawm cov cuab yeej siv kev ruaj ntseg (xws li, SIL 3.) Kev kaw qhov rooj kaw thaum muaj xwm txheej ceev yog qhov kev ntsuas tseem ceeb.
IV. INTRODUCTION Cov txheej txheem ua haujlwm
Cov xwm txheej tshwm sim: tsuas yog rau cov xwm txheej xwm txheej ceev xws li cov khoom siv tsis ua haujlwm lossis kev pheej hmoo ntawm tus kheej raug mob. Nws raug txwv los ua lwm txoj hauv kev kaw cov txheej txheem tsis tu ncua.
Rov pib txheej txheem:
Kev tshem tawm ntawm qhov chaw muaj kev phom sij (xws li, tshem tawm lub zog, cais cov khoom siv);
Kev tuav kev sib hloov / rub lub khawm pib dua;
Ua ntej rov pib lub cuab yeej, koj yuav tsum ua haujlwm (xws li CNC tshuab cuab yeej) uas rov qab mus rau qhov chaw siv.
