Network optimization data: With the increase of pressure, high-pressure oil acts on the upper end of the guide plug through the nozzle, pushing the guide rod and the control valve core. Because this thrust is greater than the force of the adjusting spring, the control valve core moves downward to make high-pressure oil flow into the lower chamber of the variable piston through a transverse hole. At this time, the oil pressure at the upper and lower ends of the variable piston is equal, but the area at the lower end is larger than that at the upper end

Network optimization data: When the rotor and stator are joined, seven sealing cavities are formed. The cavity on one side of the stator and rotor centerline is connected with the inlet and outlet, and the oil return port on the other side is connected. When high-pressure oil enters cavities 1, 2 and 3 through the oil distribution mechanism, these cavities gradually become larger, the rotor rotates clockwise in the stator, while cavities 4, 5, 6 and 7 become smaller, and the oil in these cavities is discharged, thus ensuring that

Network optimization data: From the end of World War II to the 1950s, hydraulic technology quickly entered the civil field, and has been greatly developed in machine tools, engineering machinery, agricultural machinery, automobiles, ships and other fields. In the mechanical industry, hydraulic profiling devices, automatic hydraulic transmission machine tools, modular machine tools and automatic lines have emerged. In the hydraulic control system, the electro-hydraulic servo system has also been further improved, such as

Network optimization data: low speed high torque hydraulic motor. The output torque of low speed hydraulic motors is generally large (from thousands to tens of thousands of Newtons), so it is also called low speed high torque hydraulic motors. The main characteristics of the BM cycloidal hydraulic motor are large torque and good low-speed stability (generally stable operation below 10r/min, some can be as low as 0.5r/min
