The utility model discloses a driving type hydraulic oil cylinder, which relates to the technical field of hydraulic oil cylinders and comprises a hydraulic oil cylinder main body, a filtering component and a buffering component, the filtering
assembly comprises a mounting seat, an
oil pump main body, an oil outlet
pipe, a filtering seat, a mounting block, a first threaded bolt, a filtering cavity, a limiting plate, a first filtering net, a second threaded bolt and a second filtering net, the mounting seat is mounted at the right end of the hydraulic oil cylinder main body, the
oil pump main body is mounted at the upper end of the inner wall of the mounting seat, and the oil outlet
pipe is mounted at the left end of the
oil pump main body. When hydraulic oil returns to the oil pump body through the oil outlet
pipe, the hydraulic oil is filtered through the second filter screen and the first filter screen in the filter cavity and then injected into the oil pump body again, impurities, particles and pollutants in the hydraulic
oil can be effectively intercepted and removed, and stable operation of a
system is ensured; and faults or abnormities caused by
pollution are reduced.
