D88尊龙判斷燃氣發電機組故障有三種方式:

There are three ways to judge a gas turbine fault:

天然氣發電機組故障的時候,要注意自行診斷。一方面看天然氣發電機組的故障范圍,一方面究其原因,因癥施治。不可能設計出一種自診斷系統對其所有可能產生的故障都能進行診斷,因此,以直觀診斷方法為主進行檢查和判斷的工作在任何時候對任何系統來說,都是不可替代的。通過看、聽、試等方式掌握天然氣發電機組的故障特點。

Pay attention to self diagnosis when the gas generator sets are out of order. On the one hand, the fault scope of natural gas generator sets is investigated. On the one hand, the reasons are discussed. It is impossible to create a diagnosis, self diagnosis system can all of its possible fault so the inspection and judgment in an intuitive diagnosis method based work at any time on any system, are irreplaceable. Mastering the fault characteristics of natural gas generator sets by means of watching, listening and testing.

1、看:看天然氣發電機組系統類型、機型等等,判斷具體的故障根源。檢查真空軟管是否老化、破裂或擠壞,并檢查真空軟管經過的途徑和接頭是否良好。檢查控系統線束的連接狀況,如傳感器、執行器的電器是否良好,線束間的連接是否松動或斷開,電線是否有磨破或線間短路現象,電連接器的插頭和插座有無腐蝕現象等。

D88尊龙1: look at the natural gas generator system type, type, etc., to determine the specific root cause of the failure. Check whether the vacuum hose is aging, broken or squeezed, and check the way the vacuum hose passes and whether the joint is good or not. Check the connection status of control system of wire harness, such as sensors and actuators of the electric wire harness is good, whether the connection between loose or broken wires are worn or short line, plug and socket connector has no corrosion phenomenon.

2、聽:主要是聽機組工作時的聲音,有無爆震,有無敲缸,有無失速,各個不同部件的不同工作噪聲有無異常等。這需要長期的經驗累積才能準確判斷。

D88尊龙2: Listen: mainly listen to the work of the unit when the sound, whether or not knock, whether knock cylinder, whether stall, different parts of the different work noise, such as abnormal. This requires long-term experience to accumulate to be able to judge accurately.

3、試:主要是根據前述檢查,有針對性的試機,以便進異步確定故障。

3, test: mainly in accordance with the foregoing inspection, targeted testing machine, in order to enter the asynchronous to determine the failure.
