Molamu oa Piston oa Hydraulic o Ikhethileng ka ho Fetisisa
Selelekela sa Sehlahisoa
Karolo e ka sehloohong ea molamu oa rona oa piston oa silindara ea hydraulic ke sebopeho sa tšepe sa boleng bo holimo se fetang ts'ebetsong e thata ea ho betla ka chrome. Ts'ebetso ena e kenyelletsa ho betla ka electroplating lera la chromium holim'a molamu, e leng se fellang ka bokaholimo bo thata, bo boreleli le bo tšoarellang haholo. Ho betla ka chrome e thata ha ho ntlafatse botle ba palo feela, empa hape ho fana ka tšireletso e phahameng khahlanong le ho tsofala, ho ngoatheha le ho bola, ho netefatsa bophelo bo bolelele ba ts'ebeletso esita le libakeng tse thata ka ho fetisisa.
Lihlahisoa tsa rona li etselitsoe ho fihlela maemo a indasteri bakeng sa boleng le ts'epo. Thupa e 'ngoe le e 'ngoe ea piston e feta mehatong e tiileng ea taolo ea boleng ho netefatsa hore e fihlela maemo a holimo ka ho fetisisa a ho nepahala le ts'ebetso. Boitlamo bona ba boleng le botsitso bo etsa hore lihlahisoa tsa rona e be khetho e tšepahalang bakeng sa lits'ebetso tsa bohlokoa moo ts'epo e leng ea bohlokoa.
Litšebeletso tse ikhethileng
E 'ngoe ea likarolo tsa bohlokoa tsa lithupa tsa rona tsa piston ke ho iketsetsa tsona. Rea utloisisa hore lits'ebetso tse fapaneng li hloka liparamente tse itseng tsa moralo, 'me lihlahisoa tsa rona li ka fetoloa ho fihlela litlhoko tse ikhethang tsa bareki ba rona. Ebang ke bophara bo itseng, bolelele kapa qetello ea bokaholimo, re na le bokhoni ba ho fana ka tharollo e ikhethileng e fihlelang litlhoko tsa sistimi ea hau ea hydraulic ka botlalo.
Ntle le ho tšoarella ka tsela e ikhethang le ho iketsetsa lintho ka tsela e ikhethang, lithupa tsa rona tsa piston tsa silindara ea hydraulic li entsoe ho fana ka ts'ebetso e ntle ka ho fetisisa. Bokaholimo bo thata bo koahetsoeng ka chrome bo netefatsa khohlano le ho tsofala ho fokolang, ho lumella silindara ea hydraulic ho sebetsa hantle le ka katleho. Sena ha se ntlafatse ts'ebetso eohle ea sistimi feela empa hape se fokotsa litlhoko tsa tlhokomelo, e leng se fellang ka ho boloka litšenyehelo le tlhahiso e eketsehileng.
Ho tenyetseha ha liropo tsa rona tsa silindara tsa hydraulic ho etsa hore li lokele mefuta e mengata ea lits'ebetso tsa indasteri, ho kenyeletsoa lisebelisoa tsa kaho, mechini ea temo, litsamaiso tsa ho sebetsana le thepa le tse ling. Ebang ke ho phahamisa mosebetsi o boima, ho sututsa kapa ho hula, lihlahisoa tsa rona li entsoe ka boqapi ho fana ka ts'ebetso e tšepahalang le e tsitsitseng tlas'a maemo a fapaneng a ts'ebetso.
