Summarizing two-pump control
|
This final discussion on the two-pump control method will cover two different configurations of this energy-saving servo system and also present a method whereby any of the configurations could be applied to manually controlled mobile equipment.
Alternative methods
There are at least three viable configurations of the two-pump servo system. The first method was shown last month. In a second method, Figure 1, Pump B must supply makeup flow to Pump A when the cylinder extends. Thi...
