卡特彼勒CAT柴油發動機增壓器修理技術

Caterpillar repair technology of CAT diesel engine turbocharger

卡特彼勒柴油機后面上有兩個增壓器，增壓器透平與排氣支管相連接，增壓器壓氣機與中冷器連接。

There are two supercharger behind Caterpillar diesel engine, turbocharger turbine and the exhaust pipes are connected, the turbocharger compressor connected with intercooler.

廢氣進入透平殼體，推動透平葉輪，使透平和壓氣機轉動達到每分鐘70,000轉（70,000rPM）。

Exhaust gas into the turbine housing, promote the turbine impeller, the turbine and compressor rotating at 70000 revolutions per minute (70000rPM).

卡特彼勒CAT柴油發動機壓氣機葉輪(４)的轉動，吸入新鮮空氣濾清器到壓氣機殼體空氣進口(10)，壓氣機葉輪片壓縮進入空氣，因為壓縮空氣可以使卡特彼勒柴油機燃燒更多的燃油，發出較大效率，因而卡特彼勒柴油機的功率增加。

Caterpillar CAT diesel engine compressor impeller (4) rotation, breathe the fresh air filter to the compressor casing air inlet (10), compressor impeller blade compressed into the air, because compressed air can make Caterpillar diesel more fuel burner, a greater efficiency, thus increasing Caterpillar diesel engine power.

增壓器每分鐘最大轉數為噴油量所控制，為高的調整空載每分鐘轉數和卡特彼勒柴油機工作的海拔高度所控制。

Turbocharger control revolutions per minute for the fuel injection quantity, control to adjust idle high revolutions per minute and Caterpillar diesel engine working altitude.

注意

Be careful

如果高的空載轉速或噴油量大于給定噴油量(相對于卡特彼勒柴油機工作在某一海拔高度)，可能損壞卡特彼勒柴油機或增壓器零件，由于卡特彼勒柴油機輸出更高，超過了卡特彼勒柴油機冷卻和潤滑系統能力，當熱量和／或摩擦增加時將發生破壞。試驗適合的機器是唯一的，就是進行燃油里和高的空載轉速的調整。

If the no-load speed or the fuel injection quantity higher than a given (relative to the working Caterpillar diesel engine at a certain altitude), may damage the Caterpillar diesel or turbocharger parts, because Caterpillar diesel engine output is higher, more than Caterpillar diesel engine cooling and lubricating system, when the heat and / or friction increases will occur destruction. The test for the machine is unique, is the fuel and high idle speed adjustment.

增壓器軸承(５和７)應用卡特彼勒柴油機油在壓力作用下進行潤滑，機油通過油入口(６)進入，流經中心通道潤滑軸承，而后機油從出口(１１)流出返回到油槽。

Turbocharger bearing (5 and 7) application Caterpillar diesel engine oil lubrication under pressure, the oil through the oil entrance (6) enter, flows through the center channel lubricating bearings, then the oil from the outlet (11) returned to the oil tank outflow.
