摘要： A pulse tube refrigerator system comprises a pulse tube refrigerator and a compressor coupled together via a high pressure line and a low pressure line. Cryogenic fluid is transferred to the PTR via the high pressure line and returned to the compressor via the low pressure line. The system further comprises an acoustic tuning device coupled to the low pressure line between a low pressure output from the PTr and a lower pressure input to the compressor, such that noise and vibration in the PTR system are reduced.
摘要翻译：脉冲管制冷系统包括脉冲管制冷器和通过高压管线和低压管线连接在一起的压缩机。低温流体通过高压管线传递到PTR，并通过低压管路返回压缩机。该系统还包括耦合到低压线路之间的声调谐装置，其中PTr的低压输出与压缩机的低压输入之间，使得PTR系统中的噪声和振动减小。

摘要： A pulse tube refrigerator comprises a fixed pressure casing (3) containing cold parts and a removable pressure casing (2) containing serviceable parts. The fixed pressure casing (3) and the removable pressure casing (2) are coupled together via a joining member (1). During cooling operation the joining member (1) is arranged such that refrigerant fluid flows between the fixed and the removable casings. During servicing the joining member is arranged to cut off flow of refrigerant fluid between the fixed and removable casings, such that refrigerant in the fixed casing is trapped and parts in the removable casing are accessible for servicing. After servicing, substantially pure refrigerant fluid is pumped into the removable casing (2), the fixed and removable casings are re-joined and the joining member (1) is arranged such that refrigerant fluid flows between the casings again.
摘要翻译：脉冲管制冷器包括含有冷部件的固定压力壳体（3）和包含可使用部件的可拆卸压力壳体（2）。固定压力壳体（3）和可拆卸压力壳体（2）通过连接构件（1）联接在一起。在冷却操作期间，连接构件（1）被布置成使得制冷剂流体在固定和可移除的壳体之间流动。在维修期间，连接构件被布置成切断固定和可移除壳体之间的制冷剂流体的流动，使得固定壳体中的制冷剂被捕获，并且可移除壳体中的部件可接近以进行维修。维修后，基本上纯的制冷剂流体被泵送到可移除的壳体（2）中，固定和可移除的壳体被重新接合，并且连接构件（1）被布置成使得制冷剂流体再次在壳体之间流动。
