Izizathu zokushelela kwe-hand chain hoist

Iisandla chain hoistinguqulo ethuthukisiwe ye-pulley evamile. I-hand chain hoist isebenzisa amabhuleki ahlehlayo namaketango. Ngemva kokuba iphakamise into, into ngeke iwe (ngaphandle uma iketango liphukile noma ngokuzenzela). Ifanele ukuphakanyiswa kwebanga elifushane kwemishini encane. ezokuthutha. Inezici zamandla amancane okudonsa isongo, isisindo esilula kuqhathaniswa, ukusebenza kahle komshini nokulula ukukuthwala. Isetshenziswa kabanzi ezimbonini, ezimayini, ezindaweni zokwakha, ezikhumulweni zemikhumbi nakwezinye izindawo, futhi ingaqedela kalula ukuphakamisa amabanga amafushane kwemishini nezimpahla ezincane. Kodwa-ke, ngemva kokuyisebenzisa isikhathi eside, ezinye izinkinga, ezinkulu nezincane, zizokwenzeka nakanjani. Isibonelo, ukushelela kwe-hand chain hoist kuvamile. Ziningi izizathu zokushelela kwe-hand chain hoist, kodwa izizathu eziningi kungenxa yokuthi amabhuleki angaphakathi kwe-hand chain hoist ayagqokwa. Uma kunjalo, vele ufake ama-brake pads. Ubude besikhathi sokuphakanyiswa kweketango lezandla labakhiqizi abahlukene kanye nemikhiqizo Cha, ukuphakamisa iketango lezandla lekhwalithi enhle kuzohlala isikhathi eside.

Ama-hand chain hoist wonke asebenzisa amabhuleki e-pawl eyodwa. Uma isiphethu ku-pawl sixega, angeke kubangele ukubhuleka, ukwehluleka kwamabhuleki, nokushelela. Ngakho-ke, lapho ukushelela kwenzeka, singaqala sibheke ukuthi ngabe i-pawl. Isiphethu esikuyo sikhululekile, vele usimisele;

2. Esinye isimo ukuthi kunenkinga nge-friction plate:

① Ngesikhathi sokusetshenziswa okuqhubekayo, idiski yokushayisana izoqhubeka nokuguga. Amadiski okungqubuzana ekhwalithi ephansi kulula ukuwagqoka futhi awakwazi ukumelana nokugqoka. Zizoba mncane futhi zibe mncane, okuholela ekunciphiseni kwe-coefficient ye-friction kanye nokushelela;

② Uma ipuleti le-friction ligcotshwe ngamafutha, lizokwenza ukuthi i-coefficient ye-friction yehle, futhi vele izohambisana nokushelela.

Ipuleti le-friction elisetshenziswa ku-WUYI chain hoists linobuchwepheshe obuthuthukile futhi linozinzo oluhle nokumelana nokugqokwa okuphezulu. Ingasetshenziswa isikhathi eside futhi inwebe impilo yayo yesevisi, yenze umsebenzi wethu ube bushelelezi futhi uthembeke kakhudlwana.
