As the key parts of ship, the normal operation of Marine rudder forging is very important to the safety and performance of ship. However, due to the influence of various factors, the rudder forging may have various failures. This paper will introduce the fault diagnosis and elimination method of Marine rudder system forging in detail.
Fault diagnosis
Observation method: By observing the appearance of the rudder forging, check whether there are cracks, wear, deformation and so on. At the same time, check whether the fasteners are loose and the lubrication is good.
Sound method: By listening to the sound of the rudder forging during operation, determine whether there is an abnormal sound. For example, bearings may make abnormal noises when they are damaged.
Temperature method: By touching or using a thermometer to detect the temperature of the rudder forging, determine whether there is overheating. Excessive temperature may be caused by poor lubrication, bearing damage or motor overload.
Instrument testing method: The use of professional testing instruments to detect the rudder forging, such as vibration detector, oil analyzer, etc. These instruments can detect internal faults in rudder forgings, such as bearing wear and poor gear meshing.
Troubleshooting method
Replacement of damaged parts: For severely damaged parts, such as bearings, gears, etc., should be replaced immediately. At the same time, check whether the replacement parts are installed correctly and the fasteners are firm.
Adjust parameters: For the failure caused by improper parameter setting, such as too high motor speed, too large load, etc., the relevant parameters should be adjusted to meet the design requirements.
Repair damaged parts: For slightly damaged parts, such as bearing slight wear, aging seals, etc., can be repaired. After repair, it should be tested to ensure that its performance meets the requirements.
Strengthen maintenance: Regular maintenance of rudder forgings, including cleaning, lubrication, fastening and so on. Strengthening maintenance can prevent failure and extend service life.
Create fault files: Record each fault, including fault symptoms, causes, and troubleshooting methods. The establishment of fault files is helpful to analyze the fault law and provide reference for future maintenance.
Fault diagnosis and elimination is an important link to ensure the normal operation of Marine rudder forging. In order to improve the service life and safety of rudder forgings, it is recommended that shipowners and operators pay attention to the following points:
Strengthen daily maintenance: Check, clean, lubricate and tighten the rudder forgings regularly to ensure that they are in good working condition.
Improve the skill level of operators: strengthen the training and education of operators, so that they can master the principle, operation and maintenance knowledge of rudder forgings.
Establish a sound fault diagnosis and elimination system: Establish a sound fault diagnosis and elimination system to ensure that the fault can be found, diagnosed and eliminated in time.
Selection of high-quality spare parts and materials: selection of reliable quality, excellent performance of spare parts and materials to ensure the normal operation and service life of the rudder forging.
Strengthen communication and collaboration with manufacturers: strengthen communication and collaboration with rudder forging manufacturers, keep abreast of the development of new products and technologies, and improve the ability and efficiency of fault diagnosis and elimination.
Through the implementation of the above measures, the service life and safety of Marine rudder forging can be effectively improved, and the safe operation of the ship can be guaranteed. At the same time, it also helps to reduce maintenance costs and improve economic efficiency.
