Hydraulic Configurations Used in Hydraulic Generator Applications:
There are three commonly known approaches to hydraulic generator circuits:
1.
Load sense.
2. Bypass flow control.
3. Pressure control.
Field experience shows the most common circuit design is load sense (with proportional two way acting as the
LS orifice).
This design has difficulty with piston motors and the spikes induced by the low number of power elements.
Both the load sense and the bypass flow control approach require a fixed displacement motor of some
technology ( gear, vane, bent axis piston e.t.c. ).
Motors with integrated cartridge valves make for a cleaner installation and reduce the need for leak paths,
manifolds, hoses and fittings e.t.c. in confined spaces normally seen in generator sets.
Hydraulic Circuit Guidelines :
Min Requirements,
Disk space: 165MB (Software, GUI and National Instruments embedded drivers required).
Physical Memory: 2.5MB
Screen Resolution: 1024X768
Important Note:
• The unit is supplied with 3 default .dat files for the 3 current HGC-2 module versions available from HCT.
• If ‘On-line’ with the controller, only open the .dat file for your current model.
• If ‘Off-line’ you can open and save your customized settings to any of the three.
