How to deal with the problem of valve damage when using gas generator set? We will give you a detailed introduction as follows, please understand in detail.

　　燃氣發(fā)電機組在運行過(guò)程中，氣門(mén)是保證發(fā)動(dòng)機在進(jìn)氣階段盡可能多地吸收混合氣體或空氣的重要部件，是整個(gè)氣門(mén)分配系統在發(fā)動(dòng)機壓縮和工作階段可靠密封的重要組成部分。如果閥門(mén)發(fā)生故障，勢必影響整個(gè)燃氣發(fā)電機組的運行，還會(huì )阻礙電力的穩定輸送，所以用戶(hù)必須掌握一些閥門(mén)故障的修復方法。下面將從的角度介紹一些閥門(mén)故障排除的基本方法。

　　During the operation of gas generator set, the valve is an important part to ensure that the engine absorbs as much mixed gas or air as possible in the intake phase, and it is also an important part of the whole valve distribution system in the engine compression and working phase. If the valve fails, it will affect the operation of the whole gas-fired generator set and hinder the stable transmission of power, so the user must master some methods to repair the valve failure. The following will introduce some basic methods of valve troubleshooting from a professional point of view.

　　儀表測量方法:濰柴汽輪發(fā)電機組一般采用螺桿式壓力計。使用時(shí)，將氣缸壓力表的接頭旋進(jìn)噴油器座孔內，然后帶動(dòng)曲軸與起動(dòng)器旋轉4 ~ 6s，使柴油機轉速保持在300r/min左右。氣缸壓力表指示的壓力是被測氣缸的壓縮力。記下測量值，然后向缸內加入少量油，轉動(dòng)柴油發(fā)電機，如果測得的壓力明顯不同于正常，說(shuō)明缸內測試閥門(mén)失效。

　　Instrument measurement method: screw type pressure gauge is generally used in Weichai steam turbine generator set. When in use, screw the connector of cylinder pressure gauge into the injector seat hole, and then drive the crankshaft and starter to rotate for 4 ~ 6S, so as to maintain the diesel engine speed at about 300r / min. The pressure indicated by the cylinder pressure gauge is the compression force of the cylinder under test. Note down the measured value, then add a small amount of oil into the cylinder and turn the diesel generator. If the measured pressure is significantly different from normal, it means that the test valve in the cylinder is invalid.

　　經(jīng)驗排除法:判斷閥門(mén)故障是否有三種情況:燃氣發(fā)電機組在運行過(guò)程中速度不穩定，排氣管有“突發(fā)性、突發(fā)性”響聲，異常冒煙(黑煙或藍煙)。當柴油發(fā)電機組具有這三種工況時(shí)，采用單缸截油法確定缸的故障。首先將各氣缸的高壓管斷開(kāi)，觀(guān)察高壓管斷開(kāi)前后各氣缸的工作狀態(tài)變化。如果在氣瓶高壓油管斷開(kāi)后的后排出現黑煙消失或減弱，氣瓶就有麻煩了。如果缸內高壓油管斷開(kāi)后排黑煙或藍煙現象不消失，說(shuō)明缸內無(wú)故障。各高壓油泵油管斷開(kāi)后如未發(fā)現故障缸，應分析柴油機常見(jiàn)故障。

　　Experience elimination method: judge whether there are three kinds of valve faults: the speed of gas generator unit is unstable during operation, the exhaust pipe has "sudden, sudden" sound, and abnormal smoke (black smoke or blue smoke). When the diesel generator set has these three working conditions, the single cylinder cut-off method is used to determine the cylinder failure. First, disconnect the high-pressure pipe of each cylinder, and observe the working state change of each cylinder before and after the disconnection of the high-pressure pipe. If the black smoke disappears or weakens after the high-pressure oil pipe of the gas cylinder is disconnected, the gas cylinder will be in trouble. If the phenomenon of black smoke or blue smoke does not disappear after the high-pressure oil pipe in the cylinder is disconnected, it means there is no fault in the cylinder. If no fault cylinder is found after the oil pipe of each high-pressure oil pump is disconnected, common faults of diesel engine shall be analyzed.

　　閥門(mén)在燃氣發(fā)電機組中起著(zhù)重要的作用，一旦發(fā)生故障，必須立即找人員進(jìn)行維修。閥門(mén)屬于易損件，當嚴重燃燒或斷裂時(shí)，一般應更換同類(lèi)型的新產(chǎn)品。若錐體表面積碳過(guò)多，點(diǎn)蝕或銹蝕面積小，可用于閥門(mén)磨床或手動(dòng)研磨，以達到閥門(mén)密封燃燒室的效果。在排除故障時(shí)，工作人員一定要細心和耐心，并注意對問(wèn)題的總結和記錄，及時(shí)積累相關(guān)經(jīng)驗，以防止再次發(fā)生閥門(mén)故障。

　　The valve plays an important role in the gas generator set. Once it breaks down, it must be repaired by professionals. The valve belongs to vulnerable parts. When it is seriously burned or broken, the new products of the same type shall be replaced generally. If the surface area of the cone is too much carbon and the pitting or rusting area is small, it can be used for valve grinder or manual grinding to achieve the effect of valve sealing combustion chamber. When troubleshooting, the staff must be careful and patient, pay attention to the summary and record of problems, and timely accumulate relevant experience to prevent the valve failure again.
