Following the tracks of the test on ferrograph-analyzer for typical road-making machinery's lubricating oil,this paper analyzes the laws of change and the factors of effect about the oil sample of the direct - read on the ferrograph - analyzer, and suggests the improvement of ferrograph and the use of the ferrograph analyzing technology.
This paper introduces the application of equipment-state monitoring and trouble hunting to the administration of road-making machinery,the effect and form about the performance of state monitoring,trouble hunting as well as the analysis concerned.
The definition methods on the repair circle are briefly discussed in the article for Road-Making Machinery (RMM) by using the foundation-al theories of reliability, according to the changing regularity of EMM technical conditions and the relation between maintenance operation and working reliability. The article gives the statement on the basis of analysing the shortage of the traditional method of defining the repair circle, combining its domestic present conditions with influencing the operational factors of its life.
This paper introduced and analyzed in detail the technic-economic efficiency,in- cluding the evaluation of productivity,tech- nical level,competition determination meth- od of new technic and invention benefit. It al- so illustrated the example of calculation the Technic-economic benefit of road-making machinery,including the main technic-eco- nomic benifit index of application of road-construction machinery concerning the service probability feature.
