Yiziphi izingxenye zesikrini esidlidlizayo okufanele zigcotshwe? I-Bearing and vibration exciter

Isisetshenziswa sesikrini esidlidlizayo sakhiwe izingxenye ezihlukahlukene, njengebhokisi lesikrini, isikrini, i-eccentric shaft, i-vibration exciter, njll. Ukunakekelwa kwesikrini esidlidlizayo ukunakekelwa kwengxenye ngayinye. Phakathi kwazo, ukugcoba kuqhathaniswa nokugcinwa Kunezinto ezibalulekile, noma iyiphi imishini eyimishini idinga ukugcotshwa ukuze isebenze ngokujwayelekile. Ngakho yiziphi izingxenye zesikrini esidlidlizayo okufanele zigcotshwe?

1. I-Eccentric shaft yesikrini esidlidlizayo

Isikrini sokudlidliza semayini sizungeziswa ngokuyinhloko yi-eccentric shaft emshinini, futhi umshini uphoqeleka ukuthi ubuyele endaweni ngenduku yokuxhuma ukuze ubone okokusebenza komshini womsebenzi wokuhlola izinto. Ngesikhathi sokusetshenziswa kwesikrini esidlidlizayo, kuyadingeka ukugcina nokulungisa umshini njalo, ikakhulukazi ukugcinwa kwe-eccentric shaft, ngakho-ke kuyadingeka ukugcoba i-eccentric shaft yesikrini esidlidlizayo.

(1) Inani lamafutha elingezwe kushafti ye-eccentric yesikrini esidlidlizayo kufanele ligcwaliswe ngesigamu ukuya kokukodwa kokuthathu kwesikhala sangaphakathi se-eccentric shaft. Kufanele kuncishiswe kube ingxenye eyodwa kwezintathu lapho i-eccentric shaft isebenza ngesivinini esikhulu, ngaphandle kwalokho amafutha amaningi azokwenza ukuthi izinga lokushisa le-eccentric shaft likhuphuke futhi kulimaze imishini.

(2) Uma isikrini esidlidlizayo sisesimweni sejubane eliphezulu kanye nezinga eliphezulu lokushisa, amafutha awasakwazi ukuzivumelanisa nokugcotshwa kwe-eccentric shaft yomshini, futhi ukuthambisa uwoyela kuyadingeka. Amafutha okugcoba asetshenziswa kakhulu ahlanganisa uwoyela oyimishini, uwoyela wesilinda, uwoyela wemishini enesivinini esikhulu, uwoyela we-compressor, kanye no-Transformer Oil, uwoyela we-turbine, njll.

(3) Ngokugcotshwa kwamafutha, inani elikhulu lamandla okushisa akhiqizwa imishini lingasuswa, futhi ukudlidliza nomsindo womshini kungancishiswa.

(4) Uma ukhetha okokuthambisa kushafti ye-eccentric yesikrini esidlidlizayo, i-viscosity iyisici sayo esibalulekile, futhi i-viscosity yesigcobo kufanele ilawulwe ku-12cst-15cst. Qaphela ukuthi ukuphakama kwejubane le-eccentric shaft, i-viscosity yamafutha okugcoba iyancipha, kanye ne-viscosity yamafutha okugcoba lapho umthwalo usinda.

2. I-exciter yesikrini esidlidlizayo

Ukuze kugcotshwe i-exciter yesikrini esidlidlizayo, kufanele kukhethwe uwoyela wegiya, futhi uhlobo lukawoyela wegiya luhlukile emazingeni okushisa ahlukene.

(1) Uma izinga lokushisa lendawo lingaphansi kuka-5°C, sebenzisa uwoyela wegiya lezimboni onguNombolo 70. Uma izinga lokushisa le-ambient lingaphezulu kuka-5°C, sebenzisa uwoyela wegiya lezimboni onguNombolo 90.

(2) Ugrisi ujovwa endaweni ephakathi kwepuleti elivalayo le-exciter yesikrini esidlidlizayo kanye nendandatho yokuhlukanisa ukuze kuvalwe, futhi inkomishi kawoyela isetshenziselwa ukujova igrisi ngokugcwele kanye ngesonto.

(3) Inani lomjovo kawoyela lincike kusayizi we-exciter yesikrini esidlidlizayo. Inani elincane likawoyela lehla ngokuqhubekayo liphuma, okubonisa ukuthi inani likawoyela lilungile. Uma inani elikhulu lamafutha okugcoba lichichima, izinga lamafutha liphakeme kakhulu, ngaphandle kwalokho inani lamafutha liphansi kakhulu.

(4) I-eccentric block ye-exciter yesikrini esidlidlizayo isebenza ngokuqhathaniswa ngaphansi kwesenzo samandla angaphandle; ukuthwala kwe-exciter yesikrini esidlidlizayo kufanele kugcwaliswe kabusha ngamafutha njalo, ngokuvamile kanye njalo ezinyangeni ezi-3-5;

(5) I-exciter yesikrini esidlidlizayo isebenza izinyanga ezingu-5-6, ukulungiswa okuncane kanye, nokulungiswa okukhulu kanye ngonyaka. Ukulungisa okuncane kususa uthuli nokungcola komshini. Ngaphezu kokulungiswa nokugcinwa okuncane okudingekayo, izinga lokugqoka le-bearing kumele lihlolwe, uma kunesidingo Ukushintsha ngokushesha nokugcinwa.

3. Amabhodi ahlukahlukene esikrini esidlidlizayo

Ukugcotshwa kunomthelela obalulekile empilweni yokukhathala nokungqubuzana, ukuguga, ukukhuphuka kwezinga lokushisa, ukudlidliza, njll. kokugingqa kwesikrini esidlidlizayo. Ngaphandle kokugcoba okujwayelekile, ukuthwala akukwazi ukusebenza. Ukuhlaziywa kwezizathu zokulimala kwebheringi yesikrini esidlidlizayo kubonisa ukuthi cishe u-40% womonakalo webhodi lesikrini esidlidlizayo uhlobene nokugcotshwa okungekuhle. Izindlela zokugcoba zamabheringi esikrini adlidlizayo zihlukaniswa kakhulu zibe ukuthambisa kwamafutha kanye nokugcotshwa kukawoyela.

Uma ukugcoba kusetshenziswa, ukugcoba kwamafutha amancane kuyadingeka, futhi amafutha ashintshwa ngemva kwamahora angu-40 okusebenza kokuqala, futhi umjikelezo wesevisi ojwayelekile ngemva kwalokho cishe amahora angu-800; uma ukugcoba kwamafutha kusetshenziswa, kudinga ukucatshangelwa ngokuya ngesivinini, umthwalo, izinga lokushisa, njll. yokuthwala ngesikhathi sokusebenza.

Okungenhla kuyimpendulo lapho izingxenye zesikrini esidlidlizayo zidinga ukugcotshwa, ikakhulukazi i-eccentric shaft, i-exciter kanye nezingxenye zokuthwala ezihlukahlukene zesikrini esidlidlizayo zidinga ukugcotshwa. Ingxenye eyodwa kwezintathu ukuya kokukodwa kokuthathu ifanelekile. Ukugcoba ukugcinwa kwemishini yesikrini edlidlizayo, ngakho-ke kuyadingeka ukwenza umsebenzi omuhle wokugcoba isikrini esidlidlizayo.
