壓殼出口因油氣積累而引起的增壓器壓氣端漏油：檢查增壓器，確認(rèn)增壓器是合格品，一般可以從增壓器的使用情況來分析，如使用環(huán)境灰塵大，引起空濾清器堵塞造成負(fù)壓達(dá)5.5kPa以上，即會(huì)造成增壓器壓氣端漏油；汽車在山區(qū)下大坡，沼氣發(fā)電機(jī)組不加油門低速行駛15分鐘以上，增壓器中壓葉輪背面建立不起氣封形成真空也會(huì)引起增壓器壓氣端漏油。只要經(jīng)常保養(yǎng)空濾清器，沼氣發(fā)電機(jī)組怠速時(shí)間不要過長，這種假性漏油現(xiàn)象即可排除。

Oil leakage at the compressor end of the turbocharger caused by oil and gas accumulation at the outlet of the pressure shell: Check the turbocharger and confirm that it is a qualified product. Generally, the use of the turbocharger can be analyzed. If the environment is dusty, causing blockage of the air filter and negative pressure exceeding 5.5kPa, it will cause oil leakage at the compressor end of the turbocharger; When a car is driving downhill in a mountainous area and the biogas generator set is driven at low speed without refueling for more than 15 minutes, the inability to establish a gas seal on the back of the medium pressure impeller of the turbocharger can also cause oil leakage at the compressor end. As long as the air filter is regularly maintained, the idle time of the biogas generator set should not be too long, and this false oil leakage phenomenon can be eliminated.

機(jī)油壓力過高會(huì)引起增壓器漏油：沼氣發(fā)電機(jī)組增壓器的進(jìn)油壓力過高也是引起增壓器漏油的原因之一。當(dāng)我們經(jīng)檢查確認(rèn)增壓器是合格品，而又發(fā)現(xiàn)沼氣發(fā)電機(jī)組的機(jī)油壓遠(yuǎn)高于說明書的規(guī)定，則要檢查沼氣發(fā)電機(jī)組的潤滑系統(tǒng)，調(diào)壓閥是否卡死或失靈，沼氣發(fā)電機(jī)組的機(jī)油壓力正常了，增壓器的漏油即可排除。

Excessive oil pressure can cause oil leakage in the turbocharger: Excessive inlet oil pressure in the turbocharger of a biogas generator set is also one of the reasons for oil leakage in the turbocharger. When we confirm through inspection that the turbocharger is a qualified product and find that the oil pressure of the biogas generator set is much higher than the specifications in the manual, we need to check whether the lubrication system and pressure regulating valve of the biogas generator set are stuck or malfunctioning. If the oil pressure of the biogas generator set is normal, the oil leakage of the turbocharger can be eliminated.

回油不暢會(huì)造成增壓器漏油：沼氣發(fā)電機(jī)組增壓器的回油是靠油的自重從增壓器回油管回入沼氣發(fā)電機(jī)組中，如果回油管出現(xiàn)縮節(jié)和阻塞，增壓器的回油不暢，增壓器會(huì)出現(xiàn)兩端滲漏機(jī)油。應(yīng)排除回油不暢，在增壓器完好的情況下，故障也即排除。

Poor oil return can cause oil leakage in the supercharger: The oil return of the supercharger in the biogas generator set relies on the weight of the oil to return from the supercharger oil return pipe into the biogas generator set. If the oil return pipe shrinks or is blocked, the oil return of the supercharger will be poor, and oil will leak from both ends of the supercharger. It should be ruled out that the oil return is not smooth, and the fault should be eliminated when the turbocharger is intact.

沼氣發(fā)電機(jī)組在施工中頻繁停車起動(dòng)：沼氣發(fā)電機(jī)組在施工中頻繁停車起動(dòng)，會(huì)引起增壓器中間殼渦輪端結(jié)焦；同時(shí)引起中間殼回油腔結(jié)焦，使增壓器回油腔縮小回油不暢產(chǎn)生漏油，應(yīng)檢查各易損件是否完好，并清除結(jié)焦。

Frequent stopping and starting of biogas generator units during construction: Frequent stopping and starting of biogas generator units during construction can cause coking at the turbine end of the intermediate shell of the turbocharger; At the same time, it causes coking in the intermediate shell return oil chamber, causing the turbocharger return oil chamber to shrink and the return oil to be blocked, resulting in oil leakage. It is necessary to check whether all vulnerable parts are intact and remove coking.

沼氣發(fā)電機(jī)組竄氣嚴(yán)重會(huì)造成增壓器的回油不暢、增壓器漏油：有些增壓器發(fā)現(xiàn)漏油甚至兩端漏油，經(jīng)檢查增壓器是合格品，進(jìn)油回油也正常，再進(jìn)行拆檢發(fā)現(xiàn)增壓器主軸中段有很厚的油垢還有些發(fā)硬，鏟除清洗后發(fā)現(xiàn)主軸中段變淡黃色且增壓器回油管中亦有油垢，從以上現(xiàn)象可以判斷為沼氣發(fā)電機(jī)組竄氣引起增壓器的回油不暢。更換沼氣發(fā)電機(jī)組四配套排除沼氣發(fā)電機(jī)組下竄氣，對(duì)增壓器、回油管進(jìn)行清洗，故障即可排除。

Severe gas leakage in the biogas generator set can cause poor oil return and oil leakage in the booster: some boosters are found to have oil leakage, even at both ends. After inspection, the booster is a qualified product, and the oil inlet and return are also normal. After dismantling and inspection, it was found that there is thick oil scale and some hardening in the middle section of the main shaft of the booster. After cleaning, it was found that the middle section of the main shaft has turned pale yellow and there is also oil scale in the return oil pipe of the booster, From the above phenomena, it can be inferred that the biogas generator unit's blowby caused poor oil return of the booster. Replace the four supporting biogas generator sets to eliminate the downward gas leakage of the biogas generator set, clean the booster and return oil pipe, and the fault can be eliminated.
