Mutu: Kufunika kwa zotchingira mphezi poteteza mphezi

Kuwonjezekaomanga, yomwe imadziwikanso kuti surgeomanga, ndi gawo lofunika kwambiri pa chitetezo chilichonse cha mphezi. Kugunda kwa mphezi kungakhale koopsa komanso koopsa, kotero kugwiritsa ntchitozomangira mphezindikofunikira kwambiri kuti tichepetse zotsatira za kugunda kwa mphezi. Mu blog iyi, tikambirana za kufunika kwa zotchingira mafunde pa chitetezo cha mphezi, komanso kufufuza zinthu zomwe zimapanga chotchingira mafunde chapamwamba kwambiri.

Chimodzi mwa zinthu zofunika kwambiri pa chogwirira chapamwamba ndi chotchingira cha EPDM chotsukidwa ndi sulfure chomwe chimagwiritsidwa ntchito popanga. Kugunda kwa mphezi kumapanga mavoteji ambiri omwe angawononge zida zomwe zimakhudzidwa nacho. Chotchingira cha EPDM chimathandiza kuteteza zigawo za chogwirira mwa kupereka chotchinga pakati pa voteji yapamwamba ndi zigawo zamkati za chogwirira.

Chinthu china chofunikira kwambiri pa zotchingira ma surge ndi chitetezo chawo cha semiconductor. Chishango chopangidwachi chimathandizanso kuteteza chotchingira ku ma spikes amphamvu kwambiri, chifukwa chimapereka njira yoti mphamvu yochulukirapo itayike pansi. Kuphatikiza apo, buti ya EPDM yopangidwayo imakwaniritsa zofunikira za ANSI/IEEE Standard 592, kuonetsetsa kuti imapereka chitetezo chabwino kwambiri.

Chigawo chapakati cha chipangizo chomangira magetsi ndi gawo lina lofunika kwambiri la chipangizo chomangira magetsi chapamwamba kwambiri. Chigawo chapakaticho chimakhala ndi mbale ya valve yomangira magetsi ya zinc oxide yomwe imathandizidwa ndi njira yapadera, zomwe zimapangitsa kuti ikhale yothandiza kwambiri pothana ndi kukwera kwa magetsi a mphezi. Chigawo chapakati cha chipangizocho chili ndi udindo woletsa kuwonongeka kwa magetsi kulikonse pa chipangizocho mwa kusuntha magetsi ochulukirapo kupita pansi.

Zoletsa kuthamanga kwa madzi zimaphatikizaponso ma probe omwe amapereka njira yodalirika yoyendetsera magetsi komanso kulumikizana kwa akazi. Ma probe amagwiritsidwa ntchito popewa kusinthasintha kwa magetsi pamalo olumikizirana zida. Kuphatikiza apo, waya wolimba wothira pansi ungagwiritsidwe ntchito kutulutsa mphamvu yogwira ntchito ya impulse voltage ikafika pamalo okhazikika, zomwe zimachepetsa kwambiri mwayi woti zida ziwonongeke.

Ndikofunika kudziwa kuti chomangira chiyenera kuyikidwa pamalo oyenera ndipo samalani mukachigwiritsa ntchito. Chomangira cha surge chiyenera kukhala chokhazikika bwino ndikuyikidwa pamalo omwe angathe kukonzedwa mosavuta. Komanso, chiyenera kufufuzidwa nthawi zonse kuti chitsimikizire kuti chikugwira ntchito bwino.

Mwachidule, chomangira ndi gawo lofunika kwambiri la chitetezo cha mphezi. Kuwonjezera pa kuteteza ku mphezi, kugwiritsa ntchito kwake n'kofunika kwambiri pochepetsa kuwonongeka kwa zida ndikuletsa kutayika kwa deta chifukwa cha kukwera kwa magetsi. Kumvetsetsa ntchito ya gawo lililonse la chomangira cha surge ndikofunikira kwambiri podziwa mtundu woyenera wa chomangira chogwiritsira ntchito. Ndi chomangira cha surge chapamwamba komanso kukhazikitsa ndi kukonza bwino, mabizinesi amatha kupuma momasuka podziwa kuti ali otetezeka bwino ku zotsatirapo zilizonse zoyipa zomwe zimachitika chifukwa cha mphezi.
