Description
Technical field
It is to be related to element of oil filter more specifically the present invention relates to the piece test in a kind of engine fittings
Bypass valve opening pressure detection in part.
Background technology
Engine machine oil effect be each moving parts of engine friction surface formation lubricating oil film be lubricated, subtract
Frictional resistance in puffer between relative motion parts, mitigates the abrasion of part.But itself is containing a certain amount of in machine oil
Colloid, impurity, moisture and additive, while in engine working process, debris enters in the bringing into of metal filings, air
Enter, the generation of machine oil oxide so that the debris in machine oil gradually increases.If machine oil is without filtering, lubricating oil is directly entered
The debris contained in machine oil, will be brought into the friction surface of kinematic pair by road, accelerate the abrasion of part, reduce making for engine
Use the life-span.Oil filter is exactly that there is provided the machine oil to engine washing by the filtering foreign in machine oil.
Bypass valve opening pressure in element of oil filter part is an important indicator of cleaner product performance.When
External temperature is reduced to a certain particular value or when oil filter exceeds normal useful life, and by-passing valve can be made in particular pressure
Opened with lower, allow filtered machine oil to flow directly into engine.However one, the impurity in machine oil, which can enter, to be started
Machine, but compared with the loss for not having machine oil in engine and causing for, it is much smaller.Therefore by-passing valve is in case of emergency
