style="text-indent:25px">下面來(lái)分析一下燒嘴點(diǎn)火故障原因及解決辦法：一、一般燒嘴都配備有點(diǎn)火電極及通常所說(shuō)的火花塞。首先觀察火花塞是否正常打火，若不打火，請(qǐng)確認(rèn)以下條件： 1.點(diǎn)火電極要與地極之間保持約2mm的較佳距離。 2.點(diǎn)火變壓器是否有高壓輸出：先確認(rèn)燒嘴控制器的變壓器供電端子是否有電壓輸出，然后確認(rèn)點(diǎn)火變壓器是否完好或接線是否正確。 3.點(diǎn)火電極是否在燒嘴內(nèi)部短路，造成沒(méi)有在點(diǎn)火區(qū)域打火，需查看燒嘴內(nèi)部電極絕緣情況。這個(gè)是過(guò)去在使用高壓點(diǎn)火變壓器、點(diǎn)火電極打火常見(jiàn)問(wèn)題，現(xiàn)在大多數(shù)場(chǎng)合已改用高能點(diǎn)火裝置，這個(gè)利用半導(dǎo)體放電，抗潮濕抗積碳具有自?xún)裟芰?，而且在點(diǎn)火時(shí)不需要調(diào)整點(diǎn)火距離。</p><p
