Test Method For Casters

1. Ukuhlolwa komthelela

Noma iyiphi into ingahlangana futhi ivibraye ngenxa yokuhanjiswa, ukusetshenziswa, ukugcinwa, njll., kodwa umkhiqizo uzoba nephutha noma ngisho ungasebenzi isikhathi esithile. Ifenisha ivame ukuba sengozini yokuphuka ngenxa yobukhulu bayo nesisindo, futhi ibekwe phansi ukuze kuqinisekiswe ukuthi ifenisha ibekwe noma cha. Ama-casters azinzile kufanele abe nokumelana okuhle nokuphuka. Indlela yokuhlola umthelela emandleni okuhlola ama-caster eYurophu iwukuthi: faka i-caster ngokuqondile epulatifomu yokuhlola, bese wenza isisindo esingu-5KG (±2%) siwe simahamba ukusuka phezulu kwe-200mm ukuze sithinte umphetho wewashi ye-caster. Uma kukhona amawashi amabili, kokubili amawashi kufanele athinte ngesikhathi esifanayo. Akukho ngxenye ye-caster eyamukelekile ukuba ihlukaniswe phakathi kokuhlola konke. Futhi ngemuva kokuphothulwa kokuhlola, ukuhamba kwama-casters, ukujikeleza emgqeni noma umsebenzi wokumisa akufanele kwenzeke.

2. Ukuhlolwa komthwalo okungashintshi

I-wheel evamile kufanele ihlale iqhuba kahle phansi, nokho lokho kuyisimo esingaphezu kokuba yitheory kuphela. Emaphahleni angalingani, noma lapho kudlula emaphethelweni, izindlela nezimbobo, ama-casters akhishwa okwesikhashana phansi. Ngakho-ke uma ethola umthwalo omkhulu ngokuzumayo noma uma ama-casters amathathu kweyane ethinta phansi, kufanele aphathe umthwalo wazo zonke izimpahla. Inqubo yokuhlola umthwalo omile we-caster ngokwezinga laseYurophu iwukuthi i-caster ibanjwe epulatifomu ye-test ye-steel eqondile futhi ehlanzekile ngama-screws, futhi umthwalo we-800N ufakwa ngokuqondile emkhakheni wesikhala se-caster isikhathi esingama-24H. Ngemuva kokususa umthwalo isikhathi esingama-24, isimo se-caster sihlolwa. Uma ukuguqulwa kwe-caster kungadluli ku-3% wendawo ye-wheel, futhi ukuhamba kwe-caster ngemuva kokuphothulwa kokuhlola, ukujikeleza emgqeni noma umsebenzi wokumisa awonakali, kuyi-qualifed.

3. Ukuhlolwa kokusebenza kokumelana

Lapho kuhlolwa le msebenzi, umphakeli kufanele ugcinwe dry futhi uhlanzekile. Beka umphakeli ephepheni lemetali elihlukene nomhlaba, gcina umphetho wewheeli uxhumene nephepheni lemetali, futhi ulayishe umphakeli ngama-5% kuya kwama-10% wemithwalo yayo eyinhloko. Sebenzisa umhloli we-insulation resistance value (ivoltage evulekile eyinhloko ingu-500V, inani lokuhlola elilinganisiwe lishintsha phakathi kuka-10% futhi ukulahleka kumkhiqizo akudluli ku-3W) ukukala inani lokuphikisana phakathi komphakeli nephepheni lemetali. Kubaphakeli abahambayo, ukuphikisana akufanele kudlule ku-104 ohms, kanti kubaphakeli abavikela i-static, ukuphikisana kufanele kube phakathi kuka-105 ohms no-107 ohms.

4. Ukuhlolwa kokugqoka okuphindaphindiwe

Uhlolo lokugqoka lwezikhwama lwenziwa ukuze lukhumbuze isimo sokugijima kwezikhamuzi ekusetshenzisweni kwansuku zonke. Luhlukaniswe lwabiwe lwamakhono amabili: ukuhlolwa kwezithiyo nokuhlolwa okungekho zithiyo. Faka izikhwama ngendlela efanele bese uzibeka epulatifomu yokuhlola. Umthwalo wesikhwama ngasinye sokuhlola ngu-300N. Imvamisa yokuhlola ingu-(6-8) izikhathi/min. Umjikelezo owodwa wokuhlola uhlanganisa ukuhamba emuva naphambili okungu-1M phambili no-1M emuva. Ukuhlola kwenziwa epulatifomu yokuhlola enezithiyo (izithiyo zensimbi, ububanzi obungu-50mm, ukuphakama okungu-2mm-3mm). Izikhathi eziyi-5000 (izikhwama zohlobo lwe-H) noma izikhathi eziyi-30000 (izikhwama zohlobo lwe-W). Izikhathi eziyi-70,000 (izikhwama zohlobo lwe-H) noma izikhathi eziyi-20,000 (izikhwama zohlobo lwe-W) epulatifomu yokuhlola engaphazamiseki. Akukho zikhwama noma ezinye izingxenye ezivunyelwe ukuba zihlukaniswe ngesikhathi sokuhlola. Ngemuva kokuhlola, isikhwama ngasinye kufanele sikwazi ukuhamba umsebenzi waso ojwayelekile. Ngemuva kokuhlola, imisebenzi yokugijima, yokujikeleza noma yokumisa yezikhwama akufanele ilimale.

5. Ukuphazamiseka kokugijima nokuphazamiseka kokujikeleza kokulinganisa

Lapho umphakeli eshukumisa noma efuna ukulawula indlela yokuhamba kwawo, amandla kumele adluliselwe kumphakeli ngento futhi adlule emithini ethile. Usayizi wemithini uncike ku: umthwalo, ububanzi bejika, impahla yejika, ifomu lempahla yejika, kanye nesimo sendawo lapho umphakeli ujika khona. Linda. Ukuze kuhlolwe ukumelana nokugijima, umthetho uwukufaka amajika amathathu esisekelweni esinamasango amathathu esiqinile. Ngokwezinga lokuhlola elihlukene, umthwalo wokuhlola ongu-300/600/900N (kuhlanganisa ubukhulu besisekelo) ufakwa esisekelweni. Amandla okudonsa aqondile enza amajika akwi-platform yokuhlola ahambe ngesivinini esingu-50mm/S (ukuphambuka okuvunyelwe ±5%), futhi agcine lokhu isikhathi esingu-10S. Ngenxa yamandla amakhulu okuphikisana kanye nokusheshisa lapho umphakeli uhamba ekuqaleni, amandla okudonsa aqondile akalwa ngemuva kokuhlola okwenziwe isikhathi esingu-5S, futhi usayizi wawo awudluli ku-15% womthwalo wokuhlola ukuze uthole ukufaneleka. Ukuhlolwa kokumelana kokujika kwenziwa ngokufaka omunye noma abaningi abaphakeli kumtshina wokuhlola ukuhamba okuqondile noma okuphindaphindiwe ukuze kube ne-90° kum方向 yokuhamba. Ngokwezinga lokuhlola elihlukene, umthwalo wokuhlola ongu-100/200/300N ufakwa kumphakeli ngamunye. Faka amandla okudonsa aqondile ukuze amajika akwi-platform yokuhlola ahambe ngesivinini esingu-50mm/S (ukuphambuka okuvunyelwe ±5%), futhi ajike phakathi kwesikhathi esingu-2S. Qopha amandla okudonsa aqondile aphezulu okwenza umphakeli ujike, futhi usayizi wawo awudluli ku-20% womthwalo wokuhlola ukuze uthole ukufaneleka.
