Description
Technical field
The present invention relates to a kind of power machine technical field rapid wear test system, more particularly, the present invention relates to the wear test system that a kind of novel internal combustion engine is used valve and valve retainer.
Background technology
Valve and seat ring are one of important friction pairs of engine, are operated under the high temperature impact condition, and the waste gas corrosion is arranged simultaneously, and condition of work is abominable, is easy to generate wear out failure.The operation life of valve and seat ring and reliability have determined serviceability, service life and the output power of engine to a certain extent.Particularly in recent years, along with engine, the particularly raising of the power of diesel engine and reliability requirement, this requirement to friction pair of valve and seat ring has also improved accordingly.In recent years, along with to the Study on Wear Mechanism of valve and seat ring day by day deeply, the appearance of some new materials and the use of new technology such as nano material, molten copper technology etc. have improved the abrasion condition of valve and seat ring, have strengthened its hardness and intensity.Therefore, be necessary very much fast, investigate this efficiently, reliably, investigate the pairing operating position of new material performance between the friction pair and serviceable life.
The traditional both at home and abroad valve and the test and the evaluation method of seat ring, normally on the engine complete machine, carry out, not only the cycle is long, cost is high, loss manpower but also to be subjected to influence such as environmental factor bigger, be not easy to the arrangement of data and groping of rule, the restriction of traditional valve crash speed also often adopts empirical value to limit.Except this test evaluation method, also having some scholars and producer to adopt former machine cam driving or cam-rocker arm body to drive valve tests and estimates, but can produce so virtually cam and valve retainer this to extra friction pair or cam-rocking arm; new wearing and tearing between two pairs of friction pairs of rocking arm-valve retainer; when estimating a pair of friction pair, sacrificed other a pair of or two pairs of friction pairs, so also can be to some adverse influences of generation on the accuracy of test findings and evaluation method and the precision.And because the restriction of cam profile, even by the adjusting to the valve clearance, the seating velocity of valve is also more limited, is unfavorable for progress and the periodic Control tested.Therefore, need a kind of new test method of design and system to carry out the test of valve and seat ring, estimate the performance of valve and seat ring.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of novel valve and seat ring wear test system are provided.
