Research on Automatic Booster Valve of Powered Props of Powered Supports

Abstract:

Article Preview

For the insufficient setting load of powered props of powered supports, an automatic booster valve, which can work continuously, is development by further analyzing the principle of automatic booster setting load system of powered supports. A simulation model is established based on AMESim ,and it is discussed that the internal relations between the efficiency ,pressure ratio and stroke of the automatic booster valve, the theoretical data and support are offered on solving the problem of insufficient and inhomogeneous setting force of powered support, it is shown that the automatic booster valve have the functions that lifting the leg by low pressure and mass flow and boosting automatically by high pressure and small flow,which can ensure the requirement on the setting load of powered supports, provide advantageous conditions for safety and efficiency in coal mine production.
