Description

Technical Field

[0001] The utility model relates to the technical field of automobile oil-water separators, in particular to an oil-water separator for a diesel engine. Background Art

[0002] As an important component of the fuel system of the oil production engine, the oil-water separator has the function of filtering out impurities, water and other pollutants in the fuel, providing clean fuel, preventing the rust and clogging of the fuel injector, reducing the wear on the engine cylinder liner and piston ring, etc., ensuring the smooth operation of the engine, improving reliability, and extending the service life of the engine. For example, the authorization announcement number "CN220929556U" is called an oil-water separator. Although it drives the threaded rod to rotate, because the bottom shell limits the straight plate, and the slide plate limits the limit rod, when the threaded rod drives the straight plate to move downward, the straight plate drives the limit rod to move to the left, and the limit rod drives the slide plate to move outward, the slide plate no longer fixes the blocking plate, and the blocking plate is convenient to remove and replace the filter paper, and there is no need to replace the entire oil-water separator, thereby improving the service life of the oil-water separator. However, the locking structure design of the oil-water separator blocking plate is relatively cumbersome, and the size is large, which is not convenient for the oil-water separator to be connected to the frame, and the practicality is poor. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content
