This page includes information about the entire electromechanical hydraulic control system for the soil mixer. This is a variant of CEB Press Controller v19.01
Controller Requirements
- Needs to switch a double acting cylinder while running a hydraulic motor
- Needs to cycle a dc motor for cement dosing
- Water mister solenoid
Electronics
- Mega 2560
- Relay Shield (3A)
- External Relays boards for >3A
- Fused Battery Connection
- High Pressure Switch
Hydraulics
Hydraulic Calculations
Hydraulic Cylinder Volumes. 2.5x12x1.25 Cylinder
Cap End Volume:((2.5in)/2)^2 * 3.14 * 12in =58.875 cu in
Rod Volume: ((1.25in)/2)^2 * 3.14 * 12in = 14.71875 cu in
Rod End Volume = 58.875 cu in - 14.71875 cu in = 44.15625 cu in
| Flow Rate | Extend Time | Retract Time |
|---|---|---|
| 5 GPM | 3.06s | 2.29s |
| 7.5 GPM | 2.04s | 1.53s |
| 10 GPM | 1.53s | 1.15s |
| 12.5 GPM | 1.22s | 0.92s |
| 15GPM | 1.02s | 0.76s |
