Precautions For Marine Diesel Engine Fuel Injection Equipment (1234)

2021-07-20

In marine diesel engines, the work of fuel injection equipment plays an important role in the fuel combustion process.



1) Strengthen the management of the fuel system oil circuit to ensure the normal operation of the oil separator, Bohr recoil filter, and fine filter to ensure the quality of the fuel entering the system.

2) Regular inspection and adjustment of Gaozhuang oil pumps and injectors are important contents of daily work. The inspection and adjustment of Gaozhuang oil mainly includes three aspects: ① tightness inspection; ② inspection and adjustment of oil supply timing; ③ inspection and adjustment of oil supply. The inspection content of the fuel injection equipment includes: ① the inspection and adjustment of the valve opening pressure; ② the tightness inspection; ③ the atomization quality inspection.

3) The fuel injection equipment needs to be disassembled and tested regularly to find out hidden dangers and defects and eliminate them in time. Pay attention to cleaning during disassembly and inspection. Only light diesel oil is allowed for cleaning, and cotton yarn is not allowed when wiping. Pay attention to the positioning when installing, pay attention to the combination of each sealing surface, pay attention to the relevant assembly marks.

4) When preparing for a flight, manually pump oil for each cylinder Gaozhuang oil pump one by one to lubricate the plunger and even parts, and observe the flexibility
of the plunger and its related moving parts.
