Fig. B
All accessories should be symmetrically arranged at the both sides of
diesel engine to prevent the crankshaft from being subject to the one-way
tension.
If the diesel engine is to drive the large-scale mechanical devices such as
hauler and large-scale hydraulic pump etc, the elastic coupling must be used
for connection, with coaxiality not more than φ0.15mm.
After installation,
check the accuracy of installation. In addition, periodically check the
accuracy of coaxiality for correctness, which otherwise may damage to the
crankshaft and so on.
2.4.5 Installation of intake system
In order for the diesel engine to aspirate enough fresh air during operation,
the intake inlet should be arranged at the well-ventilated position. Intake pipe
of diesel engine should not be very long, reduce the quantity of elbows and
adopt the large-arc transition. The inside diameter of intake pipe should not
be less than 120mm and the inside wall should be free of welding slag.
During installation, avoid any foreign material from getting into the intake
pipe, and ensure the connection pipe from the air cleaner to the supercharger
of diesel engine is well sealed, without any crack or leakage. The air cleaner
inlet should be properly guarded (mesh) to prevent the water or foreign
material from getting in. The air inlet should be kept away from all kinds of
thermal sources. Meanwhile, the exhaust gas should be not absorbed into the
intake pipe. If the air cleaner is arranged in engine room, engine room should
be equipped with ventilation facilities to ensure diesel engine can work
normally.
