焦化發(fā)電機組啟動(dòng)前及啟動(dòng)后要做的事項
我們都知道,當焦化發(fā)電機組平時(shí)啟動(dòng)時(shí),會(huì )消耗大量的油。根據同樣的原理,當濟柴發(fā)電機組啟動(dòng)時(shí),電動(dòng)機的電流將遠遠高于額定值,不僅如此如果焦化發(fā)電機組的使用壽命受到影響,并且消耗了更多的電力,發(fā)電機組應該在啟動(dòng)或長(cháng)期關(guān)閉后再次啟動(dòng),并且燃料系統應該首先用手動(dòng)泵排出。讓我們詳細介紹一下。。
As we all know, when the coking generator unit is started at ordinary times, a large amount of oil will be consumed. According to the same principle, when the jichai generator set is started, the current of the motor will be much higher than the rated value. Moreover, if the service life of the coking generator set is affected and more power is consumed, the generator set should be started again after the first start or long-term shutdown, and the fuel system should be discharged by a manual pump first. Let's introduce it in detail..
焦化發(fā)電機組啟動(dòng)前應看一下燃油箱油量是否足夠,各個(gè)油管及接頭有沒(méi)有出現漏油的現象;冷卻系統水量是否充足,清潔,無(wú)滲漏,風(fēng)扇皮帶松緊是否合適。檢查內燃機與發(fā)電機傳動(dòng)部分應連接可靠,輸出線(xiàn)路的導線(xiàn)絕緣良好,各儀表齊全有效。
Before starting the coking generator set, check whether the oil volume in the fuel tank is sufficient and whether there is oil leakage in each oil pipe and joint; Whether the water volume of the cooling system is sufficient, clean and free of leakage, and whether the tightness of the fan belt is appropriate. Check that the transmission part of internal combustion engine and generator shall be connected reliably, the conductor insulation of output line shall be good, and all instruments shall be complete and effective.
2、啟動(dòng)后,應低速運轉3~5分鐘,待溫度和機油壓輪均正常后,方可開(kāi)始作業(yè)。發(fā)電機在升速中應無(wú)異響,滑環(huán)及整流子上電刷接觸良好,無(wú)跳動(dòng)及冒火花現象。待運轉穩定,頻率、電壓達到額定值后,方可向外供電。
2. After starting, it shall run at low speed for 3-5 minutes, and the operation can be started only after the temperature and oil pressure wheel are normal. The generator shall have no abnormal sound during speed increase, and the brush on the slip ring and commutator shall be in good contact without jumping and sparking. After the operation is stable and the frequency and voltage reach the rated value, the external power can be supplied.
3、運行中出現異響、異味、水溫急劇上升及機油壓力急劇下降等情況時(shí),應立即停機檢查并排除故障。發(fā)電機功率因數不得超過(guò)遲相。頻率值的變動(dòng)范圍不得超過(guò)。
3. In case of abnormal sound, peculiar smell, sharp rise of water temperature and sharp drop of engine oil pressure during operation, stop the machine immediately for inspection and troubleshooting. The power factor of the generator shall not exceed the late phase. The variation range of frequency value shall not exceed.
4、焦化發(fā)電機組停止運行前應首先應該切斷各供電分路主開(kāi)關(guān),逐漸的減少載荷,然后切斷發(fā)電機供電主開(kāi)關(guān),將勵磁變阻器復回到電阻大值位置,使電壓降至低值,再切斷勵磁開(kāi)關(guān)和中性點(diǎn)接地開(kāi)關(guān),后停止內燃機運轉。
4. Before stopping the operation of the coking generator set, first cut off the main switch of each power supply branch to gradually reduce the load, then cut off the main switch of the generator power supply, return the excitation rheostat to the high resistance position, reduce the voltage to the low value, and then cut off the excitation switch and neutral point grounding switch, and then stop the operation of the internal combustion engine.
