摘要： Disclosed is a method of detecting a fault in a fluid-working machine comprising a plurality of working chambers of cyclically varying volume, each said working chamber operable to displace a volume of working fluid which is selectable for each cycle of working chamber volume to carry out a working function responsive to a received demand signal. An output parameter of the fluid working machine, which is responsive to the displacement of working fluid by one or more of the working chambers to carry out the working function, is measured. It is determined whether the measured output parameter fulfils at least one acceptable function criterion, taking into account the previously selected net displacement of working fluid by a working chamber during a cycle of working chamber volume to carry out the working function. By taking into account the previously selected net displacement of working fluid by a working chamber during a cycle of working chamber volume to carry out the working function, an unacceptable fault in a fluid-working machine may be detected if it causes one or more measured output parameter to respond in a way which would not be expected if the fluid working machine was functioning acceptably.

摘要： A fluid working machine comprises a controller (12) and a working chamber (2) of cyclically varying volume. The working, chamber has both an electronically controllable primary low pressure valve (14) and a secondary low pressure port (22) associated therewith, each of which is openable and closable in phased relation to cycles of working chamber volume to bring the working chamber into fluid communication with a low pressure manifold (16, 26). At least the primary low pressure valve is under the active control of the controller to enable the controller to determine the net displacement of fluid by the working chamber on a cycle by cycle basis. The primary low pressure valve and the secondary low pressure port are openable concurrently during a portion of at least some cycles of working chamber volume to enable fluid to flow into or out of the working chamber concurrently through both the primary low pressure valve and the secondary low pressure port. The primary low pressure valve may be closed under the active control of the controller a period of time after the secondary low pressure port closes.

摘要： An energy extraction device and method for extracting energy from a fluctuating energy flow from a renewable energy source. A hydraulic pump is driven by a rotating shaft, driven in turn by a renewable energy source. A hydraulic motor drives a load and a high pressure manifold communicates between the pump, motor and an elastically deformable fluid retaining body. The hydraulic pump and hydraulic motor comprise working chambers displacing a volume of working fluid selectable on each cycle of working chamber volume by the control of electronic valves. The pressure in the high pressure manifold is measured and the net rate of displacement of working fluid by the hydraulic pump is selected responsive thereto to regulate the torque applied to the said rotating shaft. The net rate of displacement of working fluid by the hydraulic motor is selected to smooth the energy flow to the load. The net rate of displacement of working fluid by the hydraulic motor is selected to regulate the pressure in the high pressure manifold to remain within an acceptable pressure range. Instead of tightly controlling the pressure in the high pressure manifold, it is allowed to vary and, by allowing the pressure to vary, a smooth output can be produced with high efficiency despite fluctuations in the energy flow from the renewable energy source. The pressure is more strongly controlled at the top and/or bottom of the acceptable pressure range than closer to an optimum working pressure.

摘要： A hydraulic apparatus including an electronically commutated machine having a plurality of working chambers which are controlled on each cycle of working chamber volume to carry out active or inactive cycles of working chamber volume allows only a plurality of defined fractions of cycles to be active cycles to avoid generating frequencies of active cycles which cause low frequency resonances. The demand signal may be quantised into fractions m/n where n is an integer below a threshold selected to avoid repeating patterns of active cycles of more than a cut-off length.

摘要： A method of operating a hydraulic apparatus comprising a hydraulic circuit region and hydraulic machine which is controlled to displace pulses of fluid of known volume into or out of the hydraulic circuit region, generating pulses of pressure in the hydraulic circuit region and torque in the hydraulic machine shaft. The response of parts of the hydraulic apparatus to these pulses is measured and used to determine properties of the hydraulic apparatus. The response of the pressure in the hydraulic circuit region to pulses at different pressures can be used to measure the hydraulic stiffness of parts of the hydraulic circuit region. It is possible to detect faults and to make measurements useful in subsequent operation of the hydraulic apparatus.

摘要： Industrial system with synthetically commutated variable displacement fluid working machine An injection moulding system, water jet cutting machine or other industrial system has a synthetically controlled variable displacement fluid working machine which outputs hydraulic fluid to one or more fluid consumers, such as rams or hydraulic motors, through hydraulically stiff fluid retaining volumes and receives hydraulic fluid back from one or more fluid consumers (111, 112) through the same or other said hydraulically stiff fluid retaining volumes (101, 102). Individual piston cylinder assemblies can be allocated to different outputs. There may be no valve between the machine and the consumers. A working chamber of the machine can be caused to undergo a motoring cycle to enable the machine to output more power than is received from a motor driving the machine. An accumulator can be used to provide a source of hydraulic compliance. The machine can be controlled using pressure control, flow control, feed forward control or variable power/variable power limit control.
