Drive System Analysis And Research&Development Of The Equilibrium Control Valve For The Grinding Table

The hydraulic equilibrium valve which mentioned in the thesis is an integrated valve body, It is one of key parts for the hydraulic drive system of the griding table. In this paper, Systematic analysis for equipment general situation and the hydraulic drive system which the equilibrium valve used is going on.This text carried on more clear analysis to the working principle of the equilibrium valve.With the drawing for the failure parts which get from the valve body, and cautiously investigated the technique characteristics, spoiled reason of the equilibrium valve and the difficult technique of the development, and according to the local condition, the whole technique betterment scheme for the equilibrium valve develops has been proposed. When the new drawing were ready, all of the parts for the new valve have been manufactured and assembled. For the same position as the old one used, the external structure and the shape size for the new valve is as similar as the original one. So we can keep it satisfied in the actual area.The paper has make a system simulation model, and simulated respectively the dynamic characteristic of the system where the equilibrium valve used, and under the condition of different signal inputs or loads and got the dynamic response of the pressure outputs through the valve. So we can get the verification that the mathematical models are suitable to the system, and provide a preliminary theory basis for the normal use on site.According to the making-site step, We make the reasonable arrangement. with the help of the working man, we take the new valve instead. When the test was going on, we accumulate the parameters that what we need. We got the data handling, compared the result with the simulated one, So we can make a conclusion.
