Malunga nentsimbi ye-10:10 kusasa ngoMeyi 3, 2020, kwaqhambuka umlilo kwiSakhiwo iQidi Kechuang eLinyi, kwiPhondo laseShandong, yaye umsebenzi wayevaleleke kumgangatho ophezulu wokwakha.Ngethamsanqa, wabopha intambo yokhuseleko waza wabaleka kakuhle kwintambo yokhuseleko lomlilo ngaphandle kokwenzakala.Intambo yokhuseleko lomlilo yenye yezona zinto zibalulekileyo zezixhobo ezichasayo zokulwa nomlilo, kwaye isetyenziswa kuphela ngabacimi bomlilo ukuba baphathe abantu ekulweni nomlilo kunye nokuhlangula, ukuhlangula indiza kunye noncedo lweentlekele okanye uqeqesho lwemihla ngemihla.Iintambo zokhuseleko zilukwe kwiintsinga ezenziweyo, ezinokuthi zohlulwe zibe ziintambo zokhuseleko ezilula kunye neentambo zokhuseleko jikelele ngokomthwalo woyilo.Ngokubanzi, ubude buziimitha ezi-2, kodwa neemitha ezi-3, iimitha ezi-5, iimitha ezili-10, iimitha ezili-15, iimitha ezingama-30 njalo njalo.
I. Iimfuno zoyilo
(1) Iintambo zokhuseleko ziya kwenziwa ngeentsinga ezikrwada.
(2) Intambo yokhuseleko iya kuba yesakhiwo esiqhubekayo, kwaye inxalenye ephambili yokuthwala umthwalo iya kwenziwa ngemicu eqhubekayo.
(3) Intambo yokhuseleko kufuneka yamkele isakhiwo sentambo yesandwich.
(4) Umphezulu wentambo yokhuseleko awusayi konakala kuwo nawuphi na umatshini, kwaye yonke intambo iya kufana ngobungqimba kwaye ifane kwisakhiwo.
(5) Ubude bentambo yokhuseleko bungalungiswa ngumvelisi ngokweemfuno zabasebenzisi, kwaye kufuneka bungabi ngaphantsi kwe-10m.Zombini iziphelo zentambo nganye yokhuseleko lomlilo kufuneka zivalwe ngokufanelekileyo.Kucetyiswa ukuba uthabathe isakhiwo sekhonkco lentambo, kwaye uthunge i-50mm ngentambo encinci yento enye, itywina lokushisa kumthungo, kwaye usonge umthungo ngerabha eboshwe ngokuqinileyo okanye umkhono weplastiki.
Intambo yokhuseleko lomlilo
Okwesibini, isalathisi sokusebenza kwentambo yokhuseleko lomlilo
(1) Ukuqhawula amandla
Awona mandla anqabileyo okuqhawuka entambo yokhuseleko olulaphu kufuneka abe makhulu kunama-200N, kwaye awona mandla anqabileyo aqhawukayo entambo yokhuseleko jikelele kufuneka abe makhulu kunama-40N.
(2) Ubude
Xa umthwalo ufikelela kwi-10% yowona mandla amancinane aqhawukayo, ulwandiso lwentambo yokhuseleko kufuneka lube phakathi kwe-1% kunye ne-10%.
(3) Ububanzi
Ubukhulu bentambo yokhuseleko kufuneka bungabi ngaphantsi kwe-9.5mm kwaye bungabi ngaphezu kwe-16.0 mm.I-diameter yentambo yokhuseleko olukhanyayo kufuneka ingabi ngaphantsi kwe-9.5mm kwaye ibe ngaphantsi kwe-12.5mm;Idayamitha yentambo yokhuseleko jikelele kufuneka ingabi ngaphantsi kwe-12.5mm kwaye ingabi ngaphezu kwe-16.0 mm.
(4) Ukumelana nokushisa okuphezulu
Emva kovavanyo lokumelana nobushushu obuphezulu kwi-204 ℃ kunye ne-5 ℃, intambo yokhuseleko ayifanele ibonakale inyibilika kunye ne-coking.
Okwesithathu, ukusetyenziswa kunye nokugcinwa kwentambo yokhuseleko lomlilo
(1) Sebenzisa
Xa usebenzisa intambo yokuphuncuka, enye incam yentambo yokuphuma okanye ihuku yokhuseleko kufuneka igxininiswe kwinto eqinileyo kuqala, okanye intambo inokulimala kwindawo eqinileyo kwaye iqhagamshelwe ngehuku yokhuseleko.Qinisa ibhanti lokhuseleko, lidibanise nomsesane omilise okwe-8 kunye nentambo yokuxhoma, yandisa intambo ukusuka kumngxunya omkhulu, emva koko udlule umsesane omncinci, uvule ucango lwe-hook yesitshixo esikhulu kwaye uxhome iringi encinci ye-8-shaped. ring kwiqhaga elikhulu.Wehla ngodonga.
(2) Isondlo
1. Ukugcinwa kweentsontelo zokhuseleko lomlilo ziya kufakwa kwikontraka kwaye zihlelwe, kwaye uhlobo, amandla okuqina, ububanzi kunye nobude bentambo yokhuseleko eyakhelwe-ngaphakathi iya kuphawulwa kwindawo ecacileyo yephakheji yentambo, kunye neleyibhile kumzimba wentambo. ayiyi kushukunyiswa;
2. Jonga kanye ngekota ukuba akukho monakalo na ngentambo;Ukuba igcinwe ixesha elide, kufuneka ifakwe kwindawo eyomileyo kunye neyomoya, kwaye akufanele ibonakale kwiqondo lokushisa eliphezulu, ilangatye elivulekileyo, i-asidi eqinile kunye nezinto ezibukhali ezinzima.
3. Izixhobo ezinamagwegwe kunye nameva aziyi kusetyenziswa ngexesha lokuphatha ukuphepha ukukrwela kunye nomonakalo;
4. Ixesha lokugcinwa kweentambo zokhuseleko ezingasetyenziswanga akufanele lidlule iminyaka emi-4, kwaye akufanele lidlule iminyaka emi-2 emva kokusetyenziswa.
