The oil filter of the
diesel engine water pump is an important component of the diesel engine lubrication system. Its main function is to remove impurities such as dust, metal particles, carbon deposits, and coal smoke particles from the engine oil, thereby protecting the engine. Oil filters are divided into two types: full flow and split flow:
The full flow filter is connected in series between the oil pump and the main oil passage, and can filter all lubricating oil entering the main oil passage.
The shunt filter is connected in parallel with the main oil passage, and only a portion of the lubricating oil is sent out by the filter oil pump.
working principle
The working principle of the oil filter is as follows:
Filtering process: When the engine is running, the oil pump carries impurities into the oil filter through the inlet. Under the action of oil pressure, the oil enters the central tube through the filter paper, while impurities remain on the filter paper.
Structural composition: The oil filter consists of filter paper and housing, as well as auxiliary components such as sealing rings, springs, and bypass valves.
Maintenance and replacement cycle
In order to ensure the normal operation of the engine and extend its service life, the oil filter needs to be replaced regularly. It is usually recommended to change the oil and oil filter every 5000 kilometers or every three months. The specific replacement cycle may vary depending on the vehicle's usage and oil type. It is recommended to refer to the vehicle manual or consult professional maintenance personnel.
Comparison of different types of filters
Diesel fine filter: With high filtration efficiency, it can filter out particles of 3-5 microns, ensuring stable operation and power output of the engine.
Coarse filter: mainly responsible for intercepting larger particles to prevent the filter from blocking and affecting the operation of the pump.
In summary, the oil filter of the diesel engine water pump plays a crucial role in the lubrication system of the diesel engine, and regular maintenance and replacement are key to ensuring engine performance and lifespan.
