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.

　　燃氣發電機組在運行過程中，氣門是保證發動機在進氣階段盡可能多地吸收混合氣體或空氣的重要部件，是整個氣門分配系統在發動機壓縮和工作階段可靠密封的重要組成部分。如果閥門發生故障，勢必影響整個燃氣發電機組的運行，還會阻礙電力的穩定輸送，所以用戶必須掌握一些閥門故障的修復方法。下面將從的角度介紹一些閥門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:濰柴汽輪發電機組一般采用螺桿式壓力計。使用時，將氣缸壓力表的接頭旋進噴油器座孔內，然后帶動曲軸與起動器旋轉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，轉動柴油發電機，如果測得的壓力明顯不同于正常，說明缸內測試閥門失效。

　　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.

　　經驗排除法:判斷閥門故障是否有三種情況:燃氣發電機組在運行過程中速度不穩定，排氣管有“突發性、突發性”響聲，異常冒煙(黑煙或藍煙)。當柴油發電機組具有這三種工況時，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，觀察高壓管斷開前后各氣缸的工作狀態變化。如果在氣瓶高壓油管斷開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后排黑煙或藍煙現象不消失，說明缸內無故障。各高壓油泵油管斷開后如未發現故障缸，應分析柴油機常見故障。

　　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, dis
