What are the basic components of a hydraulic circuit?
The diameter of the hydraulic cylinder should be based on the thrust and hydraulic pressure, and the 20 MB pump is the best use of the plunger pump, controlling the two cylinders.
20 million of you will need to use the plunger pump, you need components (including auxiliary components, control components), filter, piston pump, hydraulic control one-way valve, pilot operated relief valve, pressure gauge, throttle valve, relief valve, three four-way electromagnetic directional valve. Cooler. Change the pressure valve to the pressure valve if the pressure requirement is high. The hydraulic mappe conversion can be adjusted from the pilot overflow valve. Each of the above hydraulic components can complete your hydraulic drive by just one piece.
You may need an oil pump, two three four-way electromagnetic directional valve, if simply control on a pressure relief valve control, a throttle valve adjusting flow rate (speed). Your design load and the diameter of cylinder, load pressure cylinder diameter = p?
Make a two-way control system. The diameter of the hydraulic cylinder depends on how much thrust you need
