High pressure gear pump system integration technology solutions
According to the application object and the source of power, the use of new flow matching principle, can have three types of pump control differential cylinder system integration scheme for the selection, figure 9 is the high pressure pump is driven by servo motor control system integration principle of differential cylinder.

Servo motor drive high-pressure gear pump control differential cylinder system, the hydraulic pump can be double-acting hydraulic pump, also can be the axial plunger pump, main application field is stationary automation equipment, such as light industry machinery of plastic injection molding machine, molding machinery and aerospace technology of electro-hydraulic control system.Figure 10 is a high-pressure gear pump control double bar cylinder, double pump control differential cylinder and single pump control differential cylinder three different circuits, control the same injection molding machine clamping mechanism, a work cycle energy consumption comparison results.Compared to a work cycle, using single pump is 8 kl double pump to reduce energy consumption, the system energy efficiency to 72%, from 42% double pump and pump control double bar cylinder consume the same energy.

The above: The ordinary pressure switch's main technical
