NAKAKITA pneumatic PID regulator (hereinafter referred to as the regulator) is widely used in ships, and is often used to control the water temperature of the main engine cylinder jacket, the temperature of the main engine lubricating oil, fuel viscosity and other parameters. Whether the PID parameters are set correctly…
A ship has a total of 5 auxiliary engines, using 6L23/30H diesel engine produced by MAN B&W, with a rated speed of 750r/min. When the speed exceeds 110r/min, the diesel engine starts with ignition. One day, the dock was ready to sail, and the 4# auxiliary engine failed to start,…
Combined with equipment maintenance examples, this paper first analyzes the possible causes of the fault, and then accurately locates the fault through the investigation of the working principle of each component and the cause of the fault, and solves the problem of abnormal loss of oil replenishment pressure of the…
The Freshwater Generators is an important auxiliary equipment necessary for ships to sail in the ocean. The Alfa Laval JP-26 watermaker is compact and easy to operate, and is often available on ocean-going vessels. With the aging of water-making machine equipment, abnormal faults occur frequently, which has a certain impact…
At present, marine diesel engines produced by MAN B&W are widely used as modern large-scale ship main engines. Among the diesel engine air valve mechanism and combustion chamber components, the working conditions of the air valve and valve seat are relatively harsh and the failure rate is high. They are…
