Yiziphi izinqubo zokukhiqiza izixhumi zezimoto?
1. Ubuchwepheshe bokukhiqiza obunembayo: Lobu buchwepheshe busetshenziselwa ikakhulukazi ubuchwepheshe obufana nebanga elincane nokuqina okuncane, okungaqinisekisa ukuthi inkambu yokukhiqiza enembe kakhulu ifinyelela izinga eliphezulu phakathi kontanga bomhlaba.
2. Isignali yomthombo wokukhanya nokwakheka kwe-electromechanical okuhlanganisiwe kobuchwepheshe bokuthuthukiswa: Lobu buchwepheshe bungasetshenziswa kuzixhumi zemoto ezilalelwayo ezinezingxenye ze-elekthronikhi. Ukwengeza izingxenye ze-elekthronikhi kuzixhumi zemoto kungenza izixhumi zemoto zibe nemisebenzi emibili, ukwephula umklamo wendabuko wezixhumi zemoto.
3. Ukushisa okuphansi kanye nobuchwepheshe bokubumba obuphansi kwengcindezi: Enkambweni yokukhiqiza izixhumi zemoto, ukubekwa uphawu kanye nemisebenzi encibilikayo yomzimba namakhemikhali isetshenziselwa ukwenza izixhumi zemoto zifinyelele umphumela wokushisa nokushisa. Ngemuva kwe-encapsulation, ucingo luqinisekisa ukuthi amaphuzu we-welding awadonswa amandla angaphandle, ukuqinisekisa ikhwalithi nokuthembeka kwemikhiqizo yesixhumi semoto.
Nquma ukuthi isixhumi esizenzakalelayo sinokuthenjwa okuphezulu yini?
1. Izixhumi ezinokwethenjelwa okuphezulu kufanele zibe nomsebenzi wokunciphisa ingcindezi:
Uxhumo lukagesi lwezixhumi zezimoto ngokuvamile luthwala ingcindezi enkulu kanye nengcindezi kunoxhumo lwebhodi, ngakho imikhiqizo yesixhumi idinga ukuba nemisebenzi yokukhulula ingcindezi ukuze ithuthukise ukwethembeka kwayo.
2. Izixhumi ezinokwethenjelwa okuphezulu kufanele zibe nokudlidliza okuhle kanye nokumelana nomthelela:
Izixhumi zezimoto zivame ukuthintwa ukudlidliza kanye nezici ezinomthelela, okuholela ekuphazamisekeni kokuxhumeka. Ukubhekana nezinkinga ezinjalo, izixhumi kufanele zibe nokudlidliza okuhle kanye nokumelana nomthelela ukuze kuthuthukiswe ukwethembeka kwazo.
3. Izixhumi ezinokwethenjelwa okuphezulu kufanele zibe nesakhiwo somzimba esiqinile:
Ngokungafani nokuxhumeka kukagesi okuhlukaniswe ukushaqeka kukagesi, ukubhekana nezici ezimbi ezinjengomthelela ezindaweni ezikhethekile, izixhumi kufanele zibe nesakhiwo esiqinile somzimba ukuvimbela izixhumi ekulimazeni othintana nabo phakathi nenqubo yokumatanisa ngenxa yezinto ezimbi, ngaleyo ndlela kuthuthukiswe ukwethembeka izixhumi.
4. Izixhumi ezinokwethenjelwa okuphezulu kufanele zibe nokuqina okuphezulu:
Izixhumi ezijwayelekile zezimoto zingase zibe nokuphila kwesevisi ye-plug-in izikhathi ezingu-300-500, kodwa izixhumi zezinhlelo zokusebenza ezithile zingadinga impilo yesevisi ye-plug-in izikhathi ezingu-10,000, ngakho ukuqina kwesixhumi kufanele kube phezulu, futhi kuyadingeka ukuqinisekisa ukuthi ukuqina kwesixhumi kuhlangabezana nezidingo ezijwayelekile zomjikelezo we-plug-in.
5. Ibanga lokushisa elisebenzayo lezixhumi ezinokwethenjelwa okuphezulu kufanele lihlangabezane nezicaciso:
Ngokuvamile, izinga lokushisa elisebenzayo lezixhumi zezimoto lingu-30°C kuya ku-+85°C, noma -40°C kuya ku-+105°C. Ibanga lezixhumi ezinokwethenjelwa okuphezulu lizocindezela umkhawulo ophansi uye ku -55°C noma -65°C, futhi umkhawulo ophezulu ube okungenani +125°C noma ngisho +175°C. Ngalesi sikhathi, ububanzi obungeziwe bokushisa kwesixhumi ngokuvamile bungafinyelelwa ngokukhetha izinto (ezifana ne-high-grade phosphor bronze noma i-beryllium yethusi othintana nabo), futhi impahla yegobolondo lepulasitiki idinga ukukwazi ukugcina ukuma kwayo ngaphandle kokuqhekeka noma ukukhubazeka.
Yiziphi izidingo zokuhlolwa kokuvalwa kwezixhumi zezimoto?
1. Ukuhlolwa kokuvala: Kudingeka ukuhlola ukuvalwa kwesixhumi ngaphansi kwevacuum noma ingcindezi eqondile. Ngokuvamile kudingeka ukuthi uvale umkhiqizo nge-clamp ngaphansi kwengcindezi eyakhayo noma engeyinhle engu-10kpa ukuya ku-50kpa, bese uhlola isimo somoya. Uma imfuneko iphakeme, izinga lokuvuza lomkhiqizo wokuhlola akufanele lidlule u-1cc/min noma u-0.5cc/min ukuze ube umkhiqizo ofanelekayo.
2. Ukuhlolwa kokumelana nokucindezela: Ukuhlolwa kokumelana nokucindezela kuhlukaniswe ukuhlolwa kwengcindezi engalungile kanye nokuhlolwa kokucindezela okuhle. Kudingeka ukuthi ukhethe iqembu elinembile le-valve yokulawula ngokulinganayo ukuze kuhlolwe futhi kukhishwe umkhiqizo ngesilinganiso esithile se-vacuum kusukela kungcindezi yokuqala engu-0.
Isikhathi sokuvala kanye nesilinganiso se-vacuum kuyalungiseka. Isibonelo, setha i-vacuum extractor ibe -50kpa kanye nezinga lokukhipha umoya libe ngu-10kpa/min. Ubunzima balokhu kuhlola ukuthi umhloli wokungenisa umoya noma umtshina ovuzayo uyadingeka ukuze usethe ingcindezi yokuqala yokukhishwa kwengcindezi engemihle, njengokuqala ku-0, futhi-ke, izinga lokukhipha lingasethwa futhi lishintshwe, njengokuthi kuqale ku- - 10kpa.
Njengoba sonke sazi, umhloli wokuvala uphawu noma umhloli wokungenisa umoya ufakwe i-valve yokulawula ingcindezi ye-manual noma ye-elekthronikhi, engalungisa kuphela ukucindezela ngokuvumelana nokucindezela okubekiwe. Ingcindezi yokuqala iqala ku-0, futhi amandla okuphuma ancike emthonjeni we-vacuum (ijeneretha yevacuum noma iphampu ye-vacuum). Ngemuva kokuthi umthombo we-vacuum udlule ku-valve elawula ingcindezi, isivinini sokuphuma silungisiwe, okungukuthi, singakhishwa kuphela ku-0 ukucindezela okuhleliwe okubekwe yi-valve elawula ingcindezi ngaso leso sikhathi, futhi ayikwazi ukulawula ingcindezi yokuphuma kanye nesikhathi sokungena. izilinganiso ezahlukene.
Umgomo we-positive pressure ukumelana nokuhlolwa ufana ne-negative pressure ukumelana nokuhlolwa, okungukuthi, ingcindezi yokuqala isethwe kunoma iyiphi ingcindezi, efana no-0 pressure noma 10kpa, kanye ne-gradient yokwenyuka kwengcindezi, okungukuthi, umthambeka ungasethwa, njenge-10kpa/min. Lokhu kuhlola kudinga ukuthi ukunyuka kwengcindezi kungalungiswa ngokulingana nesikhathi.
I-3.Ukuhlolwa kokuqhekeka (ukuhlolwa kokuqhuma): ihlukaniswe ukuhlolwa kokuqhuma kwengcindezi engalungile noma ukuhlolwa kwe-positive rupture test. Kudingeka ukuthi lapho i-vacuum ikhishwa noma icindezelwa ebangeni elithile lokucindezela, umkhiqizo kufanele uqhume ngokushesha, futhi ingcindezi yokuphuka kufanele irekhodwe. Ubunzima bokuhlolwa ukuthi ukucindezela okungalungile okutholwe umhloli wokuqina komoya kuhlangabezana nezidingo zokuhlolwa kwesibili, izinga lokucindezela liyalungiseka, futhi ukuqhuma kokucindezela kufanele kuqedwe ngaphakathi kwebanga elimisiwe futhi akukwazi ukulidlula.
Okusho ukuthi, ukuqhuma ngaphansi kwalolu hlu noma ukuqhuma ngaphezu kwalolu bubanzi akuhlangabezani nezidingo zokuhlolwa komkhiqizo, futhi ingcindezi yokuhlola yaleli phuzu lokuqhuma idinga ukurekhodwa. Lolu hlobo lokulinganisa ludinga idivayisi yokulwa nodlame. Ngokuvamile, idivayisi yokulwa nodlame ibeka isisetshenziswa sokuhlola kusilinda sensimbi engagqwali ukumelana nokucindezela, esidinga ukuvalwa, futhi ivalvu yokusiza enomfutho ophezulu idinga ukufakwa kusilinda sensimbi engagqwali yekhava yangaphandle ukuze kuqinisekiswe ukuphepha.
