柴油發(fā)電機(jī)組油霧保護(hù)系統(tǒng)的優(yōu)缺點(diǎn)：

該保護(hù)裝置的快速性、靈敏性無(wú)可厚非，但經(jīng)過(guò)幾年的運(yùn)行檢修發(fā)現(xiàn)，由于外界或裝置自身的原因，使得其選擇性和可靠性大大降低。比如由于潤(rùn)滑油冷卻器的泄漏（水進(jìn)入并污染了潤(rùn)滑油），油霧探測(cè)器將會(huì)感受到由于水份的增加而引起的不透明度的增加，繼而發(fā)生跳機(jī)。油霧探測(cè)器的電子元件屬于高精度元件，但因其安裝在柴油機(jī)本體上，溫度高、振動(dòng)大，工作環(huán)境極為惡劣，由此使得電子元件的老化加劇，產(chǎn)生溫度漂移，跳機(jī)的靈敏度增加，誤動(dòng)率也增加。而且該保護(hù)有時(shí)出現(xiàn)指示燈全無(wú)指示，使得保護(hù)經(jīng)常處于脫離狀態(tài)等。頻繁的保護(hù)誤動(dòng)及保護(hù)的無(wú)法就緒，不僅會(huì)造成因甩負(fù)荷而引起的材質(zhì)疲勞，壽命縮短，而且會(huì)使生產(chǎn)人員產(chǎn)生麻痹心理，認(rèn)為該裝置不可靠，是誤動(dòng)，這樣大大限制并誤導(dǎo)了生產(chǎn)人員的思維，而在真正出現(xiàn)“高油霧”時(shí)就會(huì)發(fā)生事故。

Advantages and disadvantages of oil mist protection system for diesel generator set:

The speed and sensitivity of this protective device are understandable, but after several years of operation and maintenance, it has been found that due to external factors or the device itself, its selectivity and reliability have been greatly reduced. For example, due to leakage of the lubricating oil cooler (water entering and contaminating the lubricating oil), the oil mist detector will feel an increase in opacity caused by the increase in moisture, leading to machine trip. The electronic components of the oil mist detector belong to high-precision components, but due to its installation on the diesel engine body, the temperature is high, the vibration is large, and the working environment is extremely harsh, which exacerbates the aging of the electronic components, generates temperature drift, increases the sensitivity of engine tripping, and increases the false alarm rate. And sometimes the indicator light of the protection is completely off, causing the protection to frequently be in a disengaged state. Frequent protection misoperation and inability to prepare protection not only cause material fatigue and shortened lifespan due to load shedding, but also create a paralyzing mentality among production personnel, thinking that the device is unreliable and is misoperated. This greatly limits and misleads the thinking of production personnel, and accidents can occur when "high oil mist" actually occurs.
