Description
Technical field
The present invention relates to detection means field, between the vibrator and fixture that particularly relate to a kind of diesel wetting quality determinator
Attachment structure.
Background technology
With the increasingly reinforcement of environmental requirement, oil product upgrading turns into inexorable trend, and the control of oil product index is also tight all the more
Lattice, the demand for testing instruments is also gradually increased.Due to the strict control of Sulfur Content in Petroleum Products, lubricity turns into a weight
The detection project wanted.Diesel fuel lubricity analyzer is the routine analysis instrument for determining diesel fuel lubricity, because its performance is determined
Determine the degree of accuracy of data, this just proposes higher requirement, therefore testing machine knot to the Stability and veracity of instrument
The design of structure is particularly important.
Diesel fuel lubricity analyzer is the instrumentation for determining fuels lubricity, by upper and lower testpieces constant
Stroke, frequency, under the conditions of normal pressure and certain Fuel temperature and aerial temperature and humidity, carry out after high-frequency reciprocating motion,
The abrasion condition of determination test part, and then the greasy property of diesel oil is evaluated, wherein representing result of the test with wear scar diameter micron.
In the prior art, when determining the poor diesel oil of lubricity using diesel fuel lubricity analyzer, due to diesel oil in itself
Lubricity is just very poor, even if the equipment generation vibration that normally operation also can be different degrees of and the problems such as noise, when vibrating larger, meeting
Make running unstable and mill spot, mill mark shape produce change.Because the precision of the test requirements document is higher, the change of mill spot slightly
Change will make final wear scar diameter data produce deviation, so that test data loses accuracy.
The structure type of existing experimental machine, can be divided into two parts:Movable part and stationary part.Movable part includes:Rub
