As an important part of the main and auxiliary mechanism of locomotive, the maintenance and maintenance of the main and auxiliary link forging is very important to ensure the normal operation of the engine. This article will introduce the maintenance and maintenance methods of the main and auxiliary connecting rod forgings in detail, in order to extend its service life and maintain stable performance.
The forging of main and auxiliary connecting rod plays the role of transferring power in the main and auxiliary mechanism of locomotive, and its normal operation is directly related to the performance and safety of the engine. Regular maintenance and maintenance can detect and solve potential problems in time, prevent small problems from turning into major failures, and ensure engine reliability and stability.
Maintenance and maintenance methods
Regular inspection: Regular inspection of the main and auxiliary mechanisms of the locomotive, focusing on the wear of the main and auxiliary connecting rod forging. Check whether fasteners such as connecting rod bolts and bearing seats are loose, and deal with abnormalities in time.
Lubrication maintenance: According to the manufacturer’s recommendation, choose appropriate lubricating oil or grease to lubricate the main and auxiliary mechanisms of the locomotive. Change the oil regularly and check the oil level in the crankcase. Keep bearing seat, connecting rod bolt and other parts clean to prevent rust.
Avoid overload operation: avoid overload operation of the engine for a long time, so as to avoid fatigue fracture of the main and auxiliary connecting rod forging under excessive stress. Arrange work tasks reasonably and avoid frequent start, stop or rapid acceleration.
Cooling system maintenance: maintain the normal operation of the engine cooling system, clean the water tank and radiator regularly, and ensure that the coolant circulation is smooth. Check the working status of the cooling fan, water pump and other components. If any abnormal parts are found, repair or replace them in time.
Preventive maintenance: Perform regular preventive maintenance as recommended by the manufacturer, such as replacing bearings, checking crankshaft wear, etc. For key parts, such as connecting rod bearings, crankshafts, etc., professional instruments should be used for testing to ensure its stable performance.
Operation specifications: The driver should strictly abide by the operating procedures to avoid bad driving habits such as rapid acceleration and sudden braking. Regular maintenance and maintenance of the engine to ensure that it is in good working condition.
Storage and transportation: In the process of storage and transportation, necessary protective measures should be taken to prevent the main and auxiliary connecting rod forgings from impact or vibration. Keep the storage environment dry and free from moisture and corrosion.
Maintenance cycle and precautions
Maintenance cycle: According to the engine model and use, develop a reasonable maintenance cycle. In general, the initial maintenance should be carried out after 200 hours of work, and subsequent maintenance can be carried out by referring to the maintenance manual provided by the manufacturer.
Note: During maintenance, follow the manufacturer’s instruction manual and use appropriate tools and accessories. For precision parts, such as bearing seats, crankshafts, etc., should be repaired and replaced by professionals. At the same time, pay attention to safe operation procedures to prevent accidents.
Through the implementation of the above maintenance and maintenance methods, the service life of the main and auxiliary connecting rod forging can be effectively extended, and the reliability and stability of the engine can be improved. At the same time, the driver and operator also need to strengthen training and education, improve their safety awareness and operational skills, to ensure the normal operation of the main and auxiliary mechanisms of the locomotive.
