摘要： A refrigeration compressor including a compressor housing, a compressor shaft rotatably positioned within the housing, a refrigerant positioned within the housing, a face seal operatively positioned between the housing and the shaft, and a lip seal operatively positioned between the housing and the shaft. The lip seal and the primary seal collectively form a seal cavity for retaining fluid adjacent to the primary seal. An inlet port is positioned adjacent to the seal cavity, and a bearing rotatably supports the shaft within the housing. The lip seal is operatively positioned between the inlet port and the bearing. A bypass channel allows fluid (e.g., oil and refrigerant) to bypass a top portion of the lip seal, thereby permitting lubrication of the bearing. The face seal includes a seal nose and a bellows operatively associated with the seal nose. The seal nose preferably includes a maximum of about 0.5 weight percent lead. For example, the seal nose can include a tin bronze alloy, such as alloy C90300.

摘要： A refrigeration compressor seal for inhibiting the loss of refrigerant between a compressor shaft and a compressor housing. The seal includes a face seal comprising a seal nose and a mating ring positioned in opposing relation to the seal nose. The mating ring includes tungsten carbide (e.g., solid tungsten carbide with 6% nickel binder). The seal nose comprises a maximum of about 0.5 weight percent lead (e.g., a low lead tin bronze allow, such as alloy C90300). A lip seal is operatively positioned between the compressor housing and the compressor shaft. The lip seal and the face seal collectively form a seal cavity for retaining fluid adjacent to the face seal. The seal assembly can further include a bypass channel for bypassing fluid around a top portion of the lip seal.

摘要翻译： 一种用于抑制压缩机轴和压缩机壳体之间的制冷剂损失的制冷压缩机密封件。 密封件包括面密封件，其包括密封鼻部和与密封鼻部相对设置的配合环。 配合环包括碳化钨（例如，具有6％镍粘合剂的固体碳化钨）。 密封鼻包括最多约0.5重量％的铅（例如，低铅锡青铜允许，例如合金C90300）。 唇形密封件可操作地定位在压缩机壳体和压缩机轴之间。 唇形密封件和表面密封件共同形成用于将流体保持在面密封附近的密封腔。 密封组件还可以包括旁路通道，用于围绕唇密封的顶部旁路流体。
