Kangani Ndinofanira Kutsiva Maslings angu ekusimudza?

A kusimudza chipfuramabwe kunokundikana panguva yekusimudza kwemaitiro. Mutoro unodonha. Hapana akazviona zvichiuya - chipfuramabwe chaitaridzika zvakanaka panguva yekutarisa kwemangwanani.

 

Mamiriro ezvinhu aya akajairika kupfuura kubvuma kwenyanzvi dzakawanda dzekubiridzira. Uye kazhinji zvinobva pakutarisisa kumwe chete: kuchengeta chipfuramabwe mubasa kwenguva yakareba.

 

Kusiyana nezvakawanda zvemaindasitiri, chipfuramabwe chinosimudza hachiuye nezuva rekupera basa rakadhindwa pane tag yacho. Vagadziri vanopa miganho yekushanda uye kuchengetedza zvinhu, asi kashoma hurongwa hwekutsiva hwakagadziriswa. Izvi zvinosiya vashandisi vekupedzisira kuti vaone kana chipfuramabwe chasvika kumagumo ehupenyu hwayo hwesevhisi.

 

Lishenflex yanga ichigadzira zvidhori zvekusimudza kweanopfuura makumi maviri emakore, uye data redu remumunda rinoratidza kuti kutsiva nguva isati yakwana kunoparadza mari, uku kunonoka kutsiva kunoisa hupenyu. Chinokosha kunzwisisa zvinhu zvinosarudza hupenyu hwesevhisi hwechokwadi-uye kuziva nguva chaiyo yekuiregedza.

 

Hunotarisirwa Hupenyu hweSevhisi neSling Type

Hapana zvipfuramabwe zviviri zvekusimudza zera nenzira imwechete. Tarisiro yehupenyu hwesevhisi inosiyana zvakanyanya nemidziyo, ine zvipfuramabwe zvekugadzira kazhinji zvine hupenyu hupfupi hwekutanga zvichienzaniswa netambo dzewaya kana cheni dzimwe nzira.

 

Pasi pemamiriro ekushanda akajairika, data yeindasitiri inoratidza kuti zvipfuramabwe zvekugadzira zvinowanzova nehupenyu hwemakore maviri-5, nepo tambo dzetambo dzinogona kugara makore 5-10 uye cheni slings inogona kudarika makore gumi nekutarisirwa kwakakodzera. Zvisinei, fungidziro idzi nhungamiro, kwete vimbiso. Chipfuramabwe chinoshandiswa munzvimbo dzakaoma kana kutakurwa nemitoro inorema chingada kutsiviwa nekukurumidza.

 

Maererano neCanadian Center for Occupational Health and Safety (CCOHS) , zvipfuramabwe zvinogadzirwa zvinonyanya kukuvadzwa nezvinhu zvakatipoteredza—chiedza chezuva, unyoro, uye tembiricha dzinopfuura 90°C (194°F) zvinogona kukuvadza zvose naironi nepolyester slings, nepo nylon slings ichikuvadzwa neacids uye polyester slings inokuvadzwa nealkalis. . Musiyano uyu wemakemikari ekupikisa idanho rakakosha rekusarudza: sekutsanangurwa kwazvinoitwa muMazzella Companies 'synthetic sling material guide, naironi inopa kupikisa kwakanyanya kune alkalis asi haina kukodzera kuratidzwa kweasidhi, nepo polyester inopesana nemaasidhi asi inoshatisa munzvimbo dzine alkaline. Kusagadzikana kwemakemikari uku kunoreva kuti zvipfuramabwe zvinoshandiswa munzvimbo dzine hutsinye zvingada kutsiviwa nguva isati yakwana.

 

Kune zvipfuramabwe zvinoshandiswa munzvimbo dzinogara dziripo dzeUV, senge nzvimbo dzekuvaka dzekunze, zviratidzo zvinoonekwa senge bleaching kana kuwedzera kuomarara zvinoratidza kudzikira uye zvinoda kubviswa nekukurumidza. Iyo Liftex Slings chengetedzo gwara inotaura kuti kukuvara kweUV kunogona kukanganisa simba rekugadzira webhu mumadhigirii akasiyana, kubva padiki kusvika pakuora zvachose.

 

Chiitiko chekugadzira cheLishenflex chinosimbisa kuti hupenyu hwebasa rechipfuramabwe hunotsanangurwa nemamiriro ayo, kwete zera rayo. Ichi ndicho chikonzero condition-based replacement ndiyo indasitiri yakanakisa tsika.

 

The Inspection-Based Replacement Approach

Panzvimbo pekutsamira pane yakatarwa nguva, iyo indasitiri yakajairwa nzira ndeyekuongorora-kwakavakirwa kutsiva: chipfuramabwe chinofanira kutsiviwa kana ongororo yaratidza kukuvadzwa kunokanganisa kushandiswa kwayo kwakachengeteka.

 

Sezvinotsanangurwa neASME B30.9, zvidhori zvinoda matanho matatu ekuongorora:

 

Inspection Type Frequency Ndiani Anoita

Pre-shandisa Tarisa Usati wasimudza wega Operator/Supervisor

Kakawanda Kuongorora Zuva Nezuva kana usati washandisa Akasarudzwa munhu

Periodic Inspection Kanenge pagore Munhu Anokwanisa/Anokwanisa

ASME inopa aya ekuwedzera nguva nenguva yekuongorora nhungamiro zvichienderana nemamiriro ebasa: Normal Service - Gore negore; Basa Rakaoma - Mwedzi kusvika Kwetatu; Special Service - Sezvinokurudzirwa nemunhu anokwanisa. Iyo CCOHS inosimbisa zvakare kuti yekuongorora frequency inofanirwa kuve yakavakirwa pakuti kakawanda sei chipfuramabwe chinoshandiswa, mhando dzekusimudza dziri kuitwa, uye ruzivo rwekare nema slings akafanana.

 

Yakanyorwa nguva nenguva yekuongorora rekodhi inodiwa paASME B30.9. Mushandirwi ane basa rekuchengetedza marekodhi ekunyatso ongororo yazvino. Kutadza kuchengetedza marekodhi ekuongorora ndechimwe chezvinhu zvinowanzoitika zvinogona kudzivirira kambani kusvika pakutevedzwa kuzere nemirairo yekuchengetedza nzvimbo yebasa.

 

Nguva Yokurega Chipfuramabwe Chekusimudza Pakarepo

Dzimwe mhando dzekukuvadzwa izvikonzero zveotomatiki zvekurega basa ipapo. Per ASME B30.9 zviyero, zvinotevera mamiriro anoda kubviswa nekukurumidza kubva kubasa:

 

Chiziviso chisipo kana chisingaverengeki

 

Acid kana caustic inopisa pamuviri wechipfuramabwe

 

Humbowo hwekukuvara kwekupisa-kunyunguduka, kutsva, kana brittle nzvimbo

 

Makomba, misodzi, kucheka, kupfeka kweabrasive, kana snags inoburitsa tambo dzepakati

 

Tambo dzepakati dzakatsemuka kana dzakakuvadzwa - kazhinji dzinoonekwa chete nekubata

 

Weld splatter inoburitsa shinda dzepakati

 

Discoloration uye nzvimbo dzakaoma kana dzakaoma pane chero chikamu chechipfuramabwe-chinogona kuratidza kukuvara kwemakemikari kana UV.

 

Mapfundo pamuviri wechipfuramabwe

 

Midziyo ine gomba, ngura, yakatsemuka, yakakombama, yakamonyoroka, kana kuputswa

 

Oregon OSHA's yakagamuchirwa mirau yekugadzira webhu slings inotsanangura imwe nzira yekubvisa: kupfeka zvisina kujairika, faibha yehupfu pakati petambo, yakatyoka kana kucheka faibha, kusiyana kwesaizi yetambo kana kutenderera, kushanduka kana kuora, uye kukanganisa kwehardware. Mitemo yacho inotsanangurawo tembiricha yakachengeteka yekushanda — synthetic web slings yepolyester nenaironi haifanirwe kushandiswa pakupisa kunodarika 180°F (82°C).

 

Chinyorwa chakakosha: Chipfuramabwe chakabatanidzwa mukudonhedza mutoro kana kufungidzira kuwanda kunofanirwa kubviswa kubva kubasa, kunyangwe kukuvara kunoonekwa kusiri pachena.

 

Kufunga Kwakakosha: UV, Kemikari, uye Kukuvadza Kupisa

Synthetic lifting slings inonyanya kunetseka nekuparara kwezvakatipoteredza izvo zvingave zvisingaonekwe nekukurumidza.

 

Kukuvadza kweUV: Kupera kwemavara ndiyo yekutanga yambiro chiratidzo. Kuratidzwa kwezuva kunopfumisa mafibhi ekugadzira, zvichideredza simba nekufamba kwenguva. Zviratidzo zvinoonekwa zvekushatiswa kweUV zvinosanganisira kuchena kunze kweruvara rwechipfuramabwe, kuwedzera kuomarara kwezvinhu zvechipfuramabwe, uye kubvongodzwa kwepasi munzvimbo dzisingawanzo kusangana nemutoro. Slings anoshandiswa munzvimbo dzinogara dziripo dzeUV dzinofanirwa kuedzwa gore negore kana kupfuura kakawanda zvichienderana nekuoma kwekuratidzwa.

 

Chemical Exposure: Sezvakataurwa neCCOHS, nylon slings inokuvadzwa neacids nepo polyester slings inokuvadzwa nealkalis. Kushandisa izvo zvisiri izvo munzvimbo isiriyo zvakanyanya kupfupisa hupenyu hwesevhisi uye zvinogona kutungamira mukukundikana kamwe kamwe. Semuenzaniso, zvipfuramabwe zvepolyester hazvifanirwe kushandiswa apo utsi, mhute, kana zvinwiwa zvecaustics zviripo, uye zvipfuramabwe zvenaironi hazvifanirwe kushandiswa pane acid kana phenolics.

 

Kukuvadza Kwekupisa: Iyo CCOHS inoona tembiricha dziri pamusoro pe90°C (194°F) sedzinokuvadza kune zvese naironi nepolyester slings. Kusiyana nekuchekwa kunooneka kana abrasion, kukuvadzwa kwekupisa kunowanzo ratidza senzvimbo dzakaomarara kana dzakatetepa dzinogona kusaonekwa panguva yekuongorora.

 

Pfupiso uye Dzinoshanda Takeaways

Kuziva nguva yekutsiva kusimudza zvipfuramabwe hakusi kwekubata nemusoro nguva yakatarwa. Inyaya yekuongorora kusingachinji, magwaro echokwadi, uye chiito chekukurumidza kana kukuvara kwaonekwa.
