However, traditional hydraulic oil pumps face many challenges during operation. With the continuous development of industrial production, the performance and reliability requirements of hydraulic systems are getting higher and higher. In the past, due to the lack of an effective oil filtering mechanism at the oil inlet end, impurities and contaminants in the hydraulic oil easily entered the oil pump, causing the oil pump to wear more severely and shorten its service life.
