The invention discloses a hydraulic machine and a double hydraulic system. The double hydraulic system comprises a first route of hydraulic system body and a second route of hydraulic system body. The double hydraulic system is of a logic linkage structure, and therefore the first route of hydraulic system body is used when the hydraulic machine is in the idle stroke (fast advancing) and the return stroke (fast retreating), and the large-flow rapid movement is achieved; high-pressure hydraulic oil is directly driven by the second route of hydraulic system body when the hydraulic machine is in the feeding stroke, and therefore the high-pressure system pressure can be directly obtained by the hydraulic machine, the higher working force can be obtained, and the overall weight of the hydraulic machine is reduced at a large proportion. By means of the double hydraulic system, the hydraulic machine can be applied under the power of 40 Mpa or higher, for instance, 40 Mpa, 55 Mpa, 70 Mpa, 100 Mpa, 120 Mpa, 150 Mpa and 200 Mpa, the overall weight of the hydraulic machine can be greatly reduced, all types of use efficiency, such as the running speed, of the hydraulic machine can be kept, and the production efficiency can be ensured.
