        瓦斯發(fā)電機噴油嘴燒熔的原因

        如今瓦斯發(fā)電機組的應用領(lǐng)域越來(lái)越多,重要性也有所提高。我們都知道噴油嘴是瓦斯發(fā)電機的主要設備之一,在使用一段時(shí)間后,有時(shí)會(huì )出現燒熔故障。下面簡(jiǎn)單分析一下瓦斯發(fā)電機噴油嘴燒熔的原因,以幫助大家快速解決問(wèn)題,保證瓦斯發(fā)電機的正常運行。
        Nowadays, the application of gas generator sets is more and more important. We all know that the fuel nozzle is one of the main equipment of the gas generator. After a period of use, sometimes there will be a burning failure. The following is a brief analysis of the reasons for the burning of the fuel nozzle of the gas generator to help you quickly solve the problem and ensure the normal operation of the gas generator.
        瓦斯發(fā)電機噴油嘴燒熔的原因
        Reasons for fuel nozzle burning of gas generator
        1、長(cháng)時(shí)間怠速運轉
        1. Long idle running
        在瓦斯機長(cháng)時(shí)間怠速運轉時(shí),由于汽缸內溫度低,燃料燃燒不充分,燃燒室和噴油嘴上容易形成積碳,至使噴油嘴工作條件惡化。尤其在冬季寒冷的氣候條件下更為嚴重。由于燃燒室有積碳,使得散熱緩慢,嚴重時(shí)會(huì )造成噴油嘴的噴孔阻塞或出現滴油現象。燃油長(cháng)時(shí)間停留在噴油嘴頭部燃燒,產(chǎn)生的局部高溫將使噴油嘴和隔熱護套燒熔。
        When the gas engine is idling for a long time, due to the low temperature in the cylinder and insufficient fuel combustion, carbon deposits are easy to form on the combustion chamber and the fuel injector, which worsens the working conditions of the fuel injector. Especially in cold weather conditions in winter. Due to the carbon deposition in the combustion chamber, the heat dissipation is slow, and in serious cases, the nozzle hole of the fuel injection nozzle will be blocked or oil dripping will occur. The fuel will stay at the nozzle head for a long time and burn, resulting in local high temperature that will cause the nozzle and thermal insulation sheath to melt.
        2、噴油時(shí)間過(guò)晚
        2. Injection time is too late
        噴油提前角過(guò)小將使噴油時(shí)間過(guò)晚,燃料燃燒情況出現惡化,如果長(cháng)時(shí)間得不到調整,局部高溫將會(huì )使噴油嘴和隔熱護套燒熔。
        If the fuel injection advance angle is too small, the fuel injection time will be too late, and the fuel combustion situation will deteriorate. If it is not adjusted for a long time, the local high temperature will cause the fuel injection nozzle and thermal insulation sheath to burn.

        3、燃油不清潔
        3. The fuel is not clean
        燃油中的有小顆粒雜質(zhì),會(huì )使噴油嘴處的針閥和針閥體磨損,嚴重時(shí)針閥卡在針閥體內。針閥卡滯后,燃油不能定時(shí)、定量、迅速地噴入燃燒室,會(huì )出現滴油或射油現象。致使燃油霧化不好,燃燒速度降低,噴油嘴處燃燒時(shí)間延長(cháng),終導致噴油嘴和隔熱護套燒熔。發(fā)生這類(lèi)故障的同時(shí),會(huì )出現瓦斯機排黑煙和抖動(dòng)現象。
        Small particle impurities in the fuel will wear the needle valve and needle valve body at the fuel injection nozzle, and the clockwise valve will be stuck in the needle valve body seriously. The needle valve is stuck, and the fuel cannot be injected into the combustion chamber in a timely, quantitative and rapid manner, resulting in oil dripping or injection. As a result, the fuel atomization is not good, the combustion speed is reduced, the combustion time at the fuel injector is prolonged, and finally the fuel injector and thermal insulation sheath are burnt. When such failures occur, the gas machine will emit black smoke and shake.
        4、裝配不當
        4. Improper assembly
        如果噴油嘴隔熱護套時(shí)未清洗干凈就安裝,噴油嘴頭和隔熱護套有間隙,使燃氣進(jìn)入間隙內,造成隔熱和散熱效果降低,噴油嘴和隔熱護套燒熔。若隔熱護套安裝過(guò)緊,噴油嘴將產(chǎn)生附加應力,在熱交變負荷和燃油噴射高壓負荷的共同作用下,會(huì )使噴油嘴頭部斷裂,針閥卡滯而滴油。除此之外,如果維修時(shí)漏裝隔熱護套,噴油嘴伸入燃燒室超過(guò)汽缸蓋底下4mm以上,也會(huì )使噴油嘴吸收的熱量增加,使噴油嘴燒熔。
        If the thermal insulation jacket of the fuel injector is not cleaned before installation, there is a gap between the fuel injector head and the thermal insulation jacket, so that the gas enters the gap, resulting in reduced thermal insulation and heat dissipation effect, and the fuel injector and the thermal insulation jacket are fused. If the thermal insulation sheath is installed too tightly, the fuel injector will generate additional stress. Under the combined action of thermal alternating load and fuel injection high-pressure load, the fuel injector head will break, the needle valve will be stuck and drip oil. In addition, if the thermal insulation jacket is not installed during maintenance, and the fuel injector extends into the combustion chamber more than 4mm below the cylinder head, the heat absorbed by the fuel injector will also increase and the fuel injector will burn.
        如果瓦斯發(fā)電機在運行中缺少冷卻液,燃燒室因得不到很好的冷卻而造成高溫,也是噴油嘴燒熔的重要原因。以上就是瓦斯發(fā)電機噴油嘴容易燒熔的幾點(diǎn)原因分析,希望對顧客朋友們有所幫助。更多使用事項就來(lái)我們網(wǎng)站http://m.elmasticar.com進(jìn)行咨詢(xún)吧!
        If the gas generator is short of coolant during operation, the combustion chamber will not be well cooled and cause high temperature, which is also an important reason for fuel nozzle melting. The above are the reasons why the fuel nozzle of gas generator is easy to burn and melt. I hope it can help customers and friends.
