Abstract
A method is provided for determining a gas charge pressure PcalcGC of a hydraulic accumulator within a hydraulic fluid system. The method includes receiving pressure decay data representing the pressure decay within a self-pressurizing hydraulic reservoir of the hydraulic fluid system as the self-pressurizing hydraulic reservoir depressurizes from an operating pressure of the self-pressurizing hydraulic reservoir towards atmospheric pressure. The method also includes calculating the gas charge pressure PcalcGC of the hydraulic accumulator using the received pressure decay data of the self-pressurizing hydraulic reservoir.
Claims20
A method for determining a gas charge pressure PcalcGC of a hydraulic accumulator within a hydraulic fluid system, the method comprising:
- receiving pressure decay data representing the pressure decay within a self-pressurizing hydraulic reservoir of the hydraulic fluid system as the self-pressurizing hydraulic reservoir depressurizes from an operating pressure of the self-pressurizing hydraulic reservoir towards atmospheric pressure;
- and
- calculating the gas charge pressure PcalcGC of the hydraulic accumulator using the received pressure decay data of the self-pressurizing hydraulic reservoir.
A hydraulic fluid system comprising:
- a self-pressurizing hydraulic reservoir having a low pressure chamber;
- a pressure sensor operatively connected to the low pressure chamber of the self-pressurizing hydraulic reservoir such that the pressure sensor is configured to measure the pressure within the low pressure chamber;
- a hydraulic accumulator fluidly connected to the self-pressurizing hydraulic reservoir;
- and
- at least one processor configured to:
- receive pressure decay data from the pressure sensor, the pressure decay data representing the pressure decay within the self-pressurizing hydraulic reservoir as the self-pressurizing hydraulic reservoir depressurizes from an operating pressure of the self-pressurizing hydraulic reservoir towards atmospheric pressure;
- and
- calculate a gas charge pressure PcalcGC of the hydraulic accumulator using the received pressure decay data of the self-pressurizing hydraulic reservoir.
One or more computer storage media having computer-executable instructions for determining a gas charge pressure PcalcGC of a hydraulic accumulator within a hydraulic fluid system that, in response to execution by a processor, cause the processor to at least:
- receive pressure decay data representing the pressure decay within a self-pressurizing hydraulic reservoir of the hydraulic fluid system as the self-pressurizing hydraulic reservoir depressurizes from an operating pressure of the self-pressurizing hydraulic reservoir towards atmospheric pressure;
- and
- calculate the gas charge pressure PcalcGC of the hydraulic accumulator using the received pressure decay data of the self-pressurizing hydraulic reservoir.
