ANALYSIS OF HYDRAULIC ROCK BREAKER

The article deals with the researches of the experimental sample of hydraulic hammer K-14 to ensure that it is working with selected scheme and constructive solutions. The problem was solved by physical model testing of hammer on the testing stand of the workshop «Hydraulics» of plant KFMP Ltd «Kazakhmys Corporation». Testing and metrology equipment was prepared. According to the results of the analysis of testing the scientific basis of the recommendations to correction of the hammer design and perspective directions of its use are presented. Tests of physical model are supplemented by simulation model researches using a computer program «Research», that provides a clarification of the influence of selected parameters of the output characteristics of the hammer.
The paper presents a new circuit breaker gidrokinematicheskaya K-14, and structural diagram of the device of temporary resistance at the flow path of the waste liquid, as well as the technical parameters breaker K-14. The article indicated by the test task, illustrated stand for hammer testing. An electrical circuit connecting the sensors unit. Showing results of the tests and the performance of the breaker K-14.
Application of energy dispersive x-ray fluorescence analysis allows simultaneous determination of up to 20–25 elements in the sample. The detection limit of elements in powder samples is n · 10–4%, in liquid samples – n · 10–7% .

Keywords

Hammer, impact hydraulic engine, impact energy, crushing, hydroimpulse tech nics, gidrokinematicheskaya diagram stand for testing the circuitry performance.
