DMASS servo hydraulic stations for paper making equipment include oil pumps, hydraulic cylinders, hydraulic operating consoles, control valves, and hydraulic components for connection to press rolls; An oil filter is arranged between the oil pump and the hydraulic cylinder for filtering the hydraulic oil in the hydraulic cylinder; The hydraulic section is provided with an accumulator for energy storage. Because the oil filter is arranged between the oil pump and the hydraulic cylinder, the oil filter can be used to clean the hydraulic oil of the hydraulic cylinder, so as to avoid the hydraulic oil of the hydraulic cylinder due to pollution and system failure, thus greatly improving the performance and service life of the hydraulic system used for the press roll of the paper machine.
