Carry out daily maintenance for gas generator in strict accordance with the requirements to ensure reliable operation of the unit. Good maintenance can ensure the reliable operation of the unit. Under normal use, the maintenance should be carried out according to the requirements of daily maintenance, weekly maintenance and monthly maintenance.

通過(guò)這些規定的保養,能及時(shí)發(fā)現機組是否存在聲音異常、動(dòng)作異常、外觀(guān)異常、溫度異常、壓力異常和氣味異常等故障現象,從而及時(shí)對機組進(jìn)行檢查和調整,進(jìn)而有針對性的加以解決,確保瓦斯發(fā)電機運行在好狀態(tài)。在這些保養要求中,要特別注意以下三個(gè)方面的檢查和保養:

Through the maintenance of these regulations, we can timely find out whether there are abnormal sound, abnormal action, abnormal appearance, abnormal temperature, abnormal pressure, abnormal smell and other fault phenomena in the unit, so as to timely check and adjust the unit, and then solve them pertinently, so as to ensure that the gas generator runs in a good state. In these maintenance requirements, special attention should be paid to the following three aspects of inspection and maintenance:

(1)潤滑系統的檢查和保養。該種類(lèi)型機組由于存在運轉部件多,運轉部件工作條件惡劣,大多處在高溫、高沖擊載荷狀態(tài)下,需要潤滑的部位較多,對潤滑系統的可靠性要求較為苛刻,因此要注意檢查潤滑油系統的油質(zhì)情況、油位情況、油溫和油壓情況,注意離心濾清器和機油濾清器的清洗,避免出現因潤滑不好造成的機組零部件磨損加劇,縮短機組零部件的使用壽命,加大維護工作量。

(1) Inspection and maintenance of lubrication system. This type of unit has many operating components, and the operating conditions of the operating components are harsh. Most of the operating components are under high temperature and high impact load. There are many parts that need to be lubricated, and the reliability of the lubrication system is more demanding. Therefore, it is necessary to pay attention to check the oil quality, oil level, oil temperature and oil pressure of the lubricating oil system, and pay attention to the cleaning of centrifugal filter and oil filter, To avoid the aggravation of the wear of the unit parts caused by poor lubrication, shorten the service life of the unit parts and increase the maintenance workload.

(2)空氣過(guò)濾器的檢查和保養?？諝膺^(guò)濾器如果運轉良好的話(huà),將有用地避免因進(jìn)氣阻力大引起的增壓壓力下降過(guò)大,進(jìn)而造成渦輪增壓器出現漏油現象；還可避免因流量減少引起的渦輪增壓器壓氣機喘振現象。因此要定期清理空氣過(guò)濾器,必要時(shí)更換新濾芯。

(2) Inspection and maintenance of air filter. If the air filter works well, it will effectively avoid the excessive pressure drop caused by the large intake resistance, which will cause the oil leakage of the turbocharger; It can also avoid the surge phenomenon of turbocharger compressor caused by flow reduction. Therefore, clean the air filter regularly and replace the filter element if necessary.

(3)相關(guān)間隙和角度的檢查和調整。主要是火花塞間隙、氣門(mén)間隙和配氣定時(shí)等的檢查和調整。機組運行一段時(shí)間后,火花塞的間隙會(huì )有所變大,這是正?，F象。

(3) Check and adjust the clearance and angle. It mainly includes the inspection and adjustment of spark plug clearance, valve clearance and valve timing. After the unit has been running for a period of time, the gap of spark plug will become larger, which is a normal phenomenon.

瓦斯發(fā)電機經(jīng)長(cháng)時(shí)間運轉后,由于配氣機構的磨損和松動(dòng)等原因,會(huì )引起氣門(mén)間隙的變化,應定期檢查并調整氣門(mén)間隙。配氣定時(shí)在正常情況下不需要進(jìn)行調整,當機組各缸工作狀態(tài)出現異常時(shí),應首先檢查指針上止點(diǎn)指示位置是否正確,檢查傳動(dòng)系統各齒輪傳動(dòng)記號是否對準,整個(gè)系統的裝配關(guān)系及氣門(mén)間隙是否正確。若經(jīng)檢查調整后,仍與規定值差異較大時(shí),則應考慮凸輪軸或齒輪傳動(dòng)件有無(wú)損壞現象,必要時(shí)進(jìn)行修復或更換。

Gas generator after a long time of operation, due to the valve train wear and loose and other reasons, will cause changes in valve clearance, should be regularly checked and adjusted valve clearance. It is not necessary to adjust the valve timing under normal conditions. When the working state of each cylinder of the unit is abnormal, it is necessary to first check whether the indication position of the top dead center of the pointer is correct, whether the gear transmission marks of the transmission system are aligned, and whether the assembly relationship and valve clearance of the whole system are correct. If there is still a big difference between the value and the specified value after inspection and adjustment, the camshaft or gear transmission parts shall be considered for damage and repaired or replaced if necessary.
