As the core power source of large ships, construction machinery, offshore platforms and nuclear power plants, the stability and reliability of internal combustion engines are of paramount importance. In order to ensure the continuous and efficient operation of internal combustion engine units, condition monitoring of their lubrication systems is particularly important. The following is a detailed analysis of the main technical indicators and their applications of the condition monitoring of internal combustion engine units you mentioned:
1. Analysis of Main Technical Indicators
1.Oil viscosity
Definition: Oil viscosity is a physical quantity to measure the size of lubricant flow resistance, which reflects the internal friction characteristics of the oil.
Importance: too low viscosity may lead to poor lubrication, increasing wear and tear of machine parts; too high viscosity may increase energy consumption, affecting the normal operation of the internal combustion engine.
Monitoring method: real-time monitoring of viscosity change of internal combustion engine oil through viscosity sensor, timely detection of viscosity abnormality, to provide a basis for the maintenance of internal combustion engine.
2.Water content
Definition: Water content refers to the content of water in internal combustion engine oil.
Importance: Excessive moisture will destroy the performance of lubricating oil, leading to poor lubrication, and even cause corrosion and wear of machine parts.
Monitoring method: using moisture sensor or capacitive sensor and other technologies, real-time monitoring of water changes in the internal combustion engine oil, to ensure the quality of oil.
3.Wear particles
Definition: Wear particles are metallic or non-metallic particles produced during the operation of internal combustion engine.
Importance: The quantity and type of wear particles can reflect the degree of wear and wear parts of the internal combustion engine, providing an important basis for fault prediction and maintenance.
Monitoring method: real-time monitoring of wear in internal combustion engine oil through iron spectrum analysis, magnetic plug detection or online particle monitoring system and other technologies.
2. sensing technology and application
1.Individual adoption:
According to customer demand and the actual situation of the internal combustion engine unit, the oil water content sensor or oil metal abrasive particle sensor can be adopted separately to monitor a specific index in real time.
This method is simple and easy to use, with low cost, and is suitable for the scenarios where a particular indicator is of special concern.
2.Multi-sensing technology joint use:
The joint use of multiple sensing technologies, such as oil water content sensor or oil metal abrasive grain sensor, can comprehensively obtain the oil quality and wear state information of the internal combustion engine unit.
Through digital fusion and analysis, accurate monitoring of the state of the internal combustion engine unit and early warning of faults can be achieved, improving the reliability and safety of the internal combustion engine unit.
This approach is suitable for scenarios that require comprehensive monitoring of the internal combustion engine unit status, such as offshore platforms, nuclear power plants and other critical areas.
Condition monitoring of internal combustion engine units is of great significance to ensure their stable and efficient operation. Through real-time monitoring of indicators such as oil viscosity, water content and wear particles, abnormalities in internal combustion units can be detected in a timely manner, providing an important basis for maintenance and fault prediction. This will help improve the reliability and safety of internal combustion engine units, reduce operation and maintenance costs, and provide a strong guarantee for the production and development of related fields. According to the customer’s needs and actual situation, you can flexibly choose to use alone or multi-sensor technology to realise the comprehensive monitoring of the status of the internal combustion engine unit.
