Embodiment Construction
[0012] refer to figure 1 , on the integral pump body (1), the passive pump mounting screw hole (2) is designed. Use the mounting screw hole (2) of the passive pump to connect to another radial piston pump of the same specification or a smaller specification to meet the large flow requirements of the overall oil supply. At the same time, the output pressure and flow of the two pumps can be adjusted separately to adapt to the The different working conditions of the whole system, combined with the improvement of the transmission shaft and the distribution shaft, can realize the double pump co-drive, and adapt to the graded oil supply and pressure adjustment requirements of the complex hydraulic system of the large radial piston pump. At the same time, the installation space is reduced, Save power.
[0013] The improvement of the pump body in cooperation with the drive shaft and the distribution shaft can realize double-pump co-drive.
[0014] When working, the hydraulic oil ent...
