High Quality Diesel Head Rotor 1 468 336 647 1468336647 For CDC 6BTA 5.9 VE Pump Parts Rotor Head Spare Part

Most of the company's current ship main engine fuel injection systems adopt the direct injection type (the high-pressure fuel discharged from the high-pressure diesel pump directly acts on the injector and is injected into the cylinder). The high-pressure diesel pump generally uses an end-point adjustable plunger pump with a diesel return hole. Structural features of diesel return hole type high-pressure diesel pump main part of diesel return hole type high-pressure diesel pump is the diesel outlet valve.

The plunger and sleeve simply adjust the gear sleeve and rack, the wave wheel and the diesel pump body. The neutral plug is the key component. There are straight grooves and inclined grooves on the upper part of the plunger. There are diesel inlet and return holes, lubricating diesel holes and diesel drain holes on the sleeve. The lug at the lower part of the plunger is in contact with the lower part of the adjusting gear sleeve. Slip fit. The ring gear on the upper part of the gear sleeve meshes with the rack. Pulling the rack can rotate the plunger. The lower end of the plunger is loaded into the guide through the spring plate and the spring, so that the plunger and the guide roller are always pressed on the cam and can slide regularly following the camshaft curve. The high-pressure diesel pump of the diesel engine, the high-pressure diesel pipe, and the fuel injector form an injection system. The high-pressure diesel pump of the diesel engine raises the fuel to a certain pressure and injects the fuel into the cylinder through the injector regularly and quantitatively according to the load of the diesel engine for combustion. Its working condition directly affects the normal operation of the diesel engine. The following takes several fault cases that have occurred during the actual operation of the ship as examples to analyze and discuss fault diagnosis and correct handling in emergencies, so as to avoid harm to the equipment or greater damage while ensuring the safety of the ship.
