摘要： A turbomachinery is presented to provide stable operation at fluid flow rates much lower than the design flow rate without introducing surge in the device. This is achieved by providing a diffuser (3) with variable angle vanes (3a). The vane angle at low flow rates is adjusted so as to minimize the diffuser loss of the exiting fluid stream from the impeller (2). Since the flow angle of the exit flow of the impeller (2) is a function only of the non-dimensional flow rates, and does not depend on the flow angle at the inlet the impeller, therefore, the vane angles can be regulated to achieve a stable operation of the impeller (2) without producing surge of the turbomachinery at flow rates lower than the design flow rate. To optimize the performance of the turbomachinery, in addition to the variable angle vanes (3a), an inlet guide vane (6) having variable vane angle is provided so that the turbomachinery can be operated at the required flow rate and head pressure. The concept is demonstrated in a turbomachinery provided with variable diffuser vanes (3a) and an inlet guide vane (6).
摘要翻译：提供了一种涡轮机构，以便在流体流动速率远低于设计流量的情况下提供稳定的操作，而不会引起装置的浪涌。这通过提供具有可变角度叶片（3a）的扩散器（3）来实现。调节低流速下的叶片角度，以使来自叶轮（2）的离开的流体流的扩散器损失最小化。由于叶轮（2）的出口流的流角仅与无量纲流量有关，而不依赖于叶轮入口处的流角，因此可以调节叶片角度以达到叶轮（2）的稳定操作，而不会以低于设计流速的流速产生涡轮机械的浪涌。为了优化涡轮机械的性能，除了可变角度叶片（3a）之外，还提供了具有可变叶片角度的入口导流叶片（6），使得涡轮机械可以以所需的流量和压头运行。该概念在具有可变扩散器叶片（3a）和入口引导叶片（6）的涡轮机械中得以证明。

摘要： A surge control system (18) for a compressor anticipates the actual surge condition and initiates anti-surge protection in proportion to the magnitude of the anticipated surge condition. This is done by providing a feed forward signal from a control station (20) to a summing station (48), along with a normally generated surge control line point, to offset this point by an amount determined by the feed forward signal. The offset point is used as an input to a controller (56) for controlling a bypass valve (28) in a bypass loop around the compressor.

摘要： @ A surge detection apparatus for use in a refrigeration system having a centrifugal compressor (12) driven by an electric motor (20) includes a first pressure transducer (32) for sensing a condenser pressure and a second pressure transducer (34) for sensing an evaporator pressure. A first bandpass digital filter (58) responsive to the condenser pressure and the evaporator pressure is provided for generating a first signal representative of the rate of change of the pressure developed across the compressor. A current transformer (24) is used to sense a current in the electric motor driving the compressor. A second bandpass digital filter (61) responsive to the motor current is provided for generating a second signal representative of the rate of change of the RMS current being drawn by the compressor drive motor. A third signal representative of a differential pressure threshold and a fourth signal representative of a first motor current threshold and a second motor current threshold are provided. A computing device (73) responsive to the first through fourth signals indicates when a valid surge is occurring in the compressor.

摘要： A control apparatus for antisurge protection of a dynamic compressor including a junction of a closed antisurge loop with a surge limit computing module and a two mode controller with a relay backup system with deviation alarms is characterized in operation in that during a slow disturbance, the two mode controller provides modulated antisurge protection by opening a relief valve. If the operating point of the compressor crosses the surge control line and during a dangerously fast disturbance, the relay backup system (119) provides antisurge protaction if a preestablished deviation of the operating point from the surge control line appears. The relay backup system (119) opens the relief valve (107) very quickly. When the relief valve (107) is so opened, the process of the user (106) of fluid from the compressor (101) is compensated by increasing the performance of the compressor (101) to maintain pressure or flow rate. Then the relay system (119) closes the relief valve (107) exponentially, which prevents a dangerous deviation of the operating point from the surge control line. In time, the surge limit line may change so that the surge control line is no longer correctly ( placed. If under such circumstances surge appears, then the backup relay system (119) opens the relief velve (107) very fast, closes it exponentially and changes the position of surge control line.
