Abstract: In response to the typical faults in the hydraulic system of a roller press caused by high dust levels and harsh working conditions, such as oil contamination, system overheating, and main cylinder oil leakage, a systematic analysis of the fault causes was conducted, and optimization measures were proposed. By adding a return oil filter and a circulating filtration cooling system, along with a design that separates the oil tank cleaning side from the return oil side, the oil cleanliness and system thermal stability were effectively improved. Additionally, through structural modifications to the main cylinder — such as adopting stepped plungers, increasing the return oil port in the oil drainage chamber, and incorporating axial main seals with a double-layer seal structure — the sealing reliability of the main cylinder was enhanced. Practical application demonstrated that after the hydraulic system improvements, the frequency of faults like valve jamming, component wear, and pressure retention failure significantly decreased. The service life of the main cylinder seals was extended from approximately 2 years to 3~5 years, effectively improving the stability and reliability of the roller press's hydraulic system while reducing equipment failure rates and maintenance costs.
