Novel hydraulic system for roller press

The novel hydraulic system for the roller press comprises an oil tank, an oil outlet of the oil tank is connected with a pump through a pipeline, an oil outlet of the pump is connected with a first high-pressure filter through a pipeline, and an oil outlet of the first high-pressure filter is connected with an electromagnetic reversing valve through a pipeline. An oil port in the left side of the top end of the electromagnetic reversing valve is connected with two loading valves through pipelines, oil ports of the loading valves are connected with oil path blocks through pipelines, oil ports in the top ends of the two oil path blocks are connected with two energy accumulators through flanges, and the other oil port in the top end of each oil path block is connected with a second high-pressure filter through a pipeline. According to the utility model, the two groups of return oil filters not only ensure the zero-load starting of the hydraulic system, but also ensure the cleanliness of return oil, the normally
