The H4U.app pQ offers additional flexibility for the implementation of hydraulic control technology.
Benefit from Bosch Rexroth's many years of extensive expertise in hydraulic control technology, while remaining within the familiar Siemens Ecosystem, without the need for additional control hardware.
It is used for the control of fixed displacement and variable displacement pumps.
Pressure control, flow control, alternating control
Fixed displacement pump with speed adjustment; variable displacement pump with continuous swivel angle adjustment at constant speed; variable displacement pump with continuous swivel
angle and speed adjustment; variable displacement pump with mechanical pressure
controller and speed adjustment
To ensure pump operation within valid operation limits, technical pump data are provided as data structure for the H4U.app pQ.
Component data are provided for Bosch Rexroth internal gear pumps type PGH/PGF and for axial piston pumps type A4VSO, A4VBO, A10VZO, A10VSO and A10FZO.
Compensates leakage that occurs in the system
Leakage calibration of pump control system, calibration of valve zero point (Pilot valve), system (plant) identification, parameter proposal
