Servo cloth after use for many years due to the thrust Division rotor servos may cause serious wear and tear sink so serious that under the rotor blades scraping the oil chamber often wear (sweep chamber), causing the rotor blades scraping the oil chamber and the gap between the increasing , the high pressure oil chamber collusion endoleaks. To avoid this, periodically renewed thrust rotor servos cloth Division and, if found rotor sweep bore Do not make a decision process should consult the servo manufacturer;
For full suspended rudder and steering gear for the aging ship rudder servo rotary vane structure, each time into the dock to the extent possible gap measure rudder cloth Secretary rudder post, because increasing the gap over the General Assembly of the rotor servos cloth Division wear;
When the rotary vane steering gear overhaul, the best steering gear manufacturer's service engineers on-site guidance and provide technical services.
Precautions sail servo (big storm weather and using large rudder angle) to strengthen the duty, always observe the servo usage, including whether abnormal sound; whether the upper and lower packing serious leak; oil level is normal; filter regular cleaning; use conditions each valve member is normal and so on, in order to identify problems in time.
Regularly check the compressor wheel and Caesar compressor diffuser and remove dirt and minimize channel resistance.
Air Cooler Cleaner regularly with circulating air cleaning surface screw unit, the air flow path a pressure not exceeding 100 Zoommwg, air cooler sea surface periodically to clear through, and enhance the cooling effect, increase the air density. The charge air temperature is lower 10 ℃, its density can be increased 3 percent, diesel power can be increased by 3.5%. 4. Every prepare the car, in the turbine inlet temperature is below 30 ℃, rinse exhaust turbine 10min. At high load, pressure water jet method, class cleaning compressor wheel l times, 45 times a 105.5.
In view of this situation, we first turbocharger was demolished seizure, carried out a careful examination, found within the compressor impeller and diffuser passage is extremely dirty, long-term oil and gas accumulation due to the Department, the suction is blocked, leading to increased -pressure drop. We conducted a thorough cleaning, and separately for coil and air-cooled exhaust gas boiler were carried out cleaning and cleaning, effectively eliminating the system dirty, reducing the intake system back pressure turbine outlet resistance and improves the supercharger the effect of cold air, so that a substantial increase in the amount of gas turbocharger, and finally to the host conditions greatly improved, so that the exhaust gas temperature dropped to less than 450 ℃, the largest oil indicating increased to 7.0 from 6.4, speed the 12kn to 14. skn, from Hong Kong ahead of 21 hours to reach the tender Jin, we received immediate effect. Turbocharged system is a system increasingly dirty, regular maintenance is particularly important. It is good or bad working conditions, will directly affect the quality of the diesel engine is directly related to the economy and security of the ship's operations. In earnestly fuel atomization work, we must give full play to the advantages of high supercharging, diesel engine work in the best condition.
