Design And Dynamic Characteristics Research Of Hydraulic System For Filter Press

First of all, according to the given parameters of filter press and process flow diagram, analysis and selection of oil cylinder of filter press, the cycle of oil way, speed control scheme, hydraulic power source. Then the hydraulic circuit of the filter press is analyzed to choose and draw up the hydraulic system schematic diagram. After that according to the execution parameters given of the hydraulic system, calculate and selection the hydraulic pump and hydraulic accessories, to determine the size of the pipe and the volume of tank. Particllarly, selection and design of oil return, in order to ensure the hydraulic system in the replacement of oil filter cartridge without downtime, selects the double barrel oil return oil filter. After the design of hydraulic system is completed, to check of the whole system, including temperature, efficiency and so on. Working principle and characteristics of press filter is introduced in the hydraulic system; After that checking and the actual use proof, the hydraulic system has the advantages of higher power consumption, low noise, good stability, reliability.Using system simulation of the AMEsim, for the flap closed standby and board motor discharge phase of filter press hydraulic system modeling and simulation analysis, obtaining the dynamic characteristic curve of actuators component for filter press. In the flap closed standby phase, dynamic simulation researching on cylinder piston stroke and speed of flap broad cylinder, volume and pressure of gas inside for accumulator, along with influence on flap cylinder speed with have or no accumulator. In the pull board motor discharge phase, dynamic simulation analysising of output torque and the output rotational speed for pull board motor and reversing or forward. Comparing changes drawing board motor no-load output torque with load output torque,The change of the output in the drawing board motor instantly start as with as reversing solenoid valve effect on motor pull board and so on. Analysising of simulation results and coming to conclusions.The comparision and analylsis of the results of simulation by changing the components parameters have been performed.
