Main functions:
- Transport regime (maintaining a constant speed of rotation of the motor shaft).
- rapid mixing mode (maximum rotation of the motor shaft).
- unloading mode (without the function of maintaining the speed).
Description of work:
- When the lever is deviated to the left to the first fixed position, the pump is controlled through the difference valve, while the speed of rotation of the motor shaft will be constant when the speed of rotation of the pump shaft changes
- With the deviation of the control lever to the left, the second fixed position, the pump controls is carried out by bypassing the valve of the difference, while the speed of rotation of the motor shaft will be maximum and vary depending on the change in the frequency of rotation of the pump shaft.
- When the control lever is deviated at an angle from 0 to 30 °, the pump control is carried out directly by the proportional power control mechanism - the pump operating volume changes in proportion to the deviation angle.
