Muzviitiko zvakaita sekutakura zvinhu nemidziyo, kubata midziyo yekutora mifananidzo, uye kuchinja kwenzvimbo dzekuchengetera zvinhu, michina haingodi chete kukwanisa kutakura huremu, asiwo inofanirwa kufunga nezvekudzivirira kusakara, runyararo, kufamba kwakasimba, uye hupenyu hwebasa. Chikonzero chikuru nei michina yepolyurethane yakanyarara ichishandiswa zvakanyanya ndechekuti inosanganisa hunhu hwezvinhu uye dhizaini yechivakwa nenzira yakaringana. Zvichitaurwa zviri nyore, zvinogona kuita kuti kufamba kwemidziyo kuve nyore uye kuchengetedza kushanda kwakasimba munzvimbo dzakawanda dzakaoma.
1. Hunhu hwakaringana hwezvinhu, kuyera kuramba kupfeka, kuderedza ruzha, uye kugona kutakura mutoro
Polyurethane, inozivikanwawo sePU, ipurasitiki inoshandiswa zvakanyanya. Chinhu chayo chakanaka chiri mukushanda kwayo kwakakura kunogadziriswa, uko kunogona kuitwa kuti kuve kwakapfava kuti kuwedzere kuvharwa kwesimbi uye kuderedza ruzha, kana kuti kuoma kuwedzera kusakara uye kugona kwayo kutakura mutoro.
Kana tichienzanisa nerabha yakajairika, polyurethane haiparare zvakanyanya uye haikurumidzi kupera nekuda kwekutenderera kwenguva refu; Kana tichienzanisa nemavhiri enylon, ine kutwasuka kuri nani, hainyanyi kukanganiswa pasi painofamba, uye ruzha rwakaderera. Nekuda kweizvi, ma polyurethane casters anowanzo shandiswa munzvimbo dzebasa dzinoda dziviriro yepasi uye kudzora ruzha.
Muchimiro, rudzi urwu rwecaster runowanzo shandisa simbi vhiri core pamwe chete ne polyurethane coating layer. Metal wheel core ine basa rekupa simba rekutsigira, nepo polyurethane outer layer ichibata pasi zvakananga uye ine basa rekubvisa shock, kuderedza ruzha, uye kuramba kupfeka. Mushure mekusanganiswa kwezvose zviri zviviri, simba rekutakura mutoro uye kugadzikana kwecaster kuchave nani.
2. Mhedzisiro iri nani yekunyarara, yakakodzera nzvimbo dzine zvinodiwa zvakanyanya zvakatipoteredza
Chimwe chinhu chikuru chinobatsira ma "polyurethane silent directional casters" ndechekuti ruzha rwakaderera panguva yekushanda. Chikonzero chacho hachina kuoma: polyurethane pachayo ine mwero wakati wekusagadzikana, iyo inogona kunwisa mamwe mavhiri kana mavhiri achitenderera, zvichideredza kudedera uye ruzha runokonzerwa nekurovera kwakasimba.
Kune mavhiri akajairika akaomarara, mipata midiki kana kusaenzana pasi zvinogona kukonzera ruzha runoonekwa rwekutenderera kana uchifamba; Mavhiri epolyurethane, nekuda kwekubatikana kwawo kwakapfava uye kufamba kwakapfava, anowanzo buritsa ruzha rwakaderera pasi pemamiriro akafanana emutoro.
Rudzi urwu rwechinhu rwakakodzera zvikuru munzvimbo dzinoda runyararo, dzakadai sekubata michina yekutora mifananidzo, kufamba kwemidziyo yekuedza, kutakurwa kwemidziyo mukati, uye dzimwe nzvimbo dzekugadzira dzinoda nzvimbo yekushandira. Mudziyo wacho wakanyarara kana uchifamba uye unobatsirawo kuderedza kukanganiswa kwekudengenyeka kwemuchina wacho.
3. Chimiro chenzira chinoita kuti kufamba kwemutsetse wakatwasuka kuve kwakasimba
Pamusoro pezvakanakira zvechinhu chacho, dhizaini yekutungamira chinhu chakakoshawo cherudzi urwu rwe caster. Iro rinonzi vhiri rekutungamira rinoreva vhiri rinogona kungofamba mberi nenzira yakatarwa uye risingakwanise kutenderera zvakasununguka sevhiri repasi rose.
Chinhu chakanaka chechimiro ichi ndechekuti chinofamba zvakadzikama mumutsara wakatwasuka, kunyanya zvakakodzera mamiriro ezvinhu akadai sekufambisa nzira yakatarwa, kusunda michina mberi nekumashure, uye kufamba kwemidziyo yekugadzira. Mudziyo uyu hauwanzokanganiswi panguva yekufamba uye uri nyore kudzora pakushanda.
Kana nzvimbo yekushandisa ichinyanya kusanganisira kufamba nenzira yakatarwa, senge mitsetse yekufambisa, nzira dzekufambisa michina inorema, kubata mifananidzo nenzira inobatsira, macaster ekutungamira anowanzo kukodzera kupfuura macaster anotenderera. Kunyangwe kuchinjika kwayo kusiri kwakanyanya sekwemavhiri epasi rose, ine zvakanakira zvakawanda mukugadzikana uye kudzora kwekutungamira.
4. Kuramba kupisa kwakanyanya, kuramba hydrolysis, kuramba mafuta, uye kuchinjika kwakasimba kwezvakatipoteredza
Zvinodiwa zvema "casters" mumaindasitiri zvinowanzosanganisira kwete kungofamba chete, asiwo kuchinjika kunzvimbo dzakaoma. Ma "casters" e "polyurethane" akanyarara anewo zvakanakira zvakakosha panyaya iyi.
Chekutanga, ine simba rekudzivirira kupfekwa kwayo uye haikurumidzi kupwanyika kana kupfekwa nekukurumidza mushure mekushandiswa kwenguva refu. Chechipiri, inokwanisa kuchinjika munzvimbo dzine hunyoro, hydrolysis, uye nzvimbo dzine kusvibiswa kwemafuta, zvichiita kuti iwanikwe zvakanyanya munzvimbo dzinotakura zvinhu, mudura, mumaworkshop, nedzimwe nzvimbo.
Zvinhu zvepolyurethane zvakagadziriswa zvishoma zvine simba rekudzivirira kupisa uye zvinogona kuchinjika kumamiriro ekushanda mukati memhando dzakasiyana dzekupisa. Izvi zvinoshanda zvakanyanya kune mamwe maworkshop anodziya zvakanyanya kana mamiriro ekushandisa ane nguva pfupi yekubata kupisa.
5. Pakusarudza, tarisa pane izvi zvitatu
Tarisa kugona kwekutakura. Pakusarudza mavhiri, hazvina kukwana kungotarisa chitarisiko nehukuru hwemavhiri, asi chinonyanya kukosha, kuona kana mutoro wakayerwa wevhiri rimwe chete uchikwanisa kusangana nehuremu hwese hwemidziyo. Kazhinji zvinokurudzirwa kusiya imwe nzvimbo zvichienderana nehuremu chaihwo, iyo yakachengeteka uye inogara kwenguva refu.
Chechipiri, tarisa dhayamita yevhiri nehukobvu hwepamusoro pevhiri. Kana dhayamita yevhiri yakakura, zviri nyore kusunda uye zviri nani kuti ifambike; Asi kana nzvimbo yekuisa iri shoma, panofanira kuva nechiyero pakati pehukuru nezvinodiwa pakushandisa.
Chechitatu, tarisa kuomarara kwacho. Kuomarara kwakanyanya, kazhinji kunodzivirira kupera uye kunotakura mutoro; Kuomarara kwacho kwakaderera kuchaita kuti pave nekugadzikana kwakanaka uye kuderedza ruzha. Kana pasi risina kutsetseka zvakakwana, fomura yepolyurethane ine kusimba kuri nani inogona kukosheswa.
6. Ndezvipi zvakanakira zvayo zvichienzaniswa nevanokanda zvinhuwo zvavo?
Kana tichienzanisa nemavhiri erabha akajairwa, mavhiri epolyurethane anowanzo dzivirira kupfekwa zviri nani uye anogara kwenguva refu. Kana tichienzanisa nemavhiri enylon, anoshanda zviri nani panyaya yekuderedza ruzha, kubatwa nekuvhunduka, uye kudzivirira pasi.
Pamusoro pezvo, musiyano uripo pakati pema "direction casters" nema "universal casters" unofanirawo kucherechedzwa. Mavhiri e "Universal" anochinjika zviri nyore uye akakodzera mamiriro ezvinhu anoda kutenderedzwa kakawanda; Mavhiri e "Directional" anonyanya kukodzera mamiriro ezvinhu apo mitsetse yakatwasuka, kugadzikana, uye kudzora nzira zvakakosha. Kune akawanda mashandisirwo ekutakura nekushandisa michina mumaindasitiri, ma "directional casters" anoshanda zvakanyanya.
Mhedziso
Kazhinji, zvakanakira zve polyurethane silent directional casters zvinonyanya kuratidzwa muzvikamu zvina: hunhu hwezvinhu hwakaringana, kushanda kwakanyarara, kufamba kwakasimba kwemutsara, uye kuchinjika kwakasimba kwezvakatipoteredza. Kune zvishandiso zvinoda kuenzana zvinotakura mutoro, zvinodzivirira kupera, zvisingatauri, uye zvinodzora divi, isarudzo inoshanda.
Pakutenga chaiko, zvinokurudzirwa kusarudza michina zvichienderana nehuremu hwayo, mamiriro evhu, nzira yekufamba, uye kushandiswa kwayo kakawanda. Kusarudza mavhiri akakodzera hakungogone chete kuvandudza kushanda kwekufamba kwemidziyo, asiwo kuderedza mari yekugadzirisa nekuitsiva padanho rekupedzisira.
