The oil fluid is filtered and cooled by the first return oil filter 11 and the cooler 12. When the first return oil filter 11 is blocked, the three-way ball valve 10 can be switched to enable the other filter oil circuit to continue working without stopping the machine to replace the filter, which improves the convenience of maintenance and the continuity of the production line.
