The Researching About Controlling Leakiness Of Series Of MXG350 Coal Cutter' Draught Hydraulic Pressure

The thesis is treating the hydroulic pressure systerm of coal cutter's draught as a representative reseaching object.It sums up theleakage reasons and the disposing mesns that often appears in the opration,in order to offer the reliable warranty about diagnoses of the hydraulic pressure systerm leaking,and eliminating.The thesis describes the governing mechanism of the hydraulic presssure systerm practicability and validity and it also describes applied technic about the leak and controling the leak the hydraulic pressure systerm particularly.It is based on the math modle of leakage analysis.We'll advise some betterment measures accroding to the existent problems,in order to increase the dependability of the systerm.Accroding to leakage pressurize between the component and the systerm,between the leakage measure in real time and the controling,we'll discuss the best of leak controlling between the component and the systerm.It analysizes leak of the component and systerm at work in dynamic and static state using qualitative and quantitative analysis,through flow and flux associatinal equation of the mainly effective loop,force balance equation and flux associatinal equation.We'll study and ameliorate or optimize the pressurized structure between the component and the systerm sothat we can bring forward some betterment measure.Finally,it aims at hitch sign and the reason from the hydraulic pressure systerm of the coal cutter's drought MXG350 and we'll offer some technic project of reducing the leak of the hydraulic pressure systerm.It is worthy to extend and apply to.
