压缩机机构和零件的油封用于该机器运输和长期保管过程中,以保证其完好无损。 在安装压缩机于操作地点前必须进行启封。为此压缩机必须进行部分拆卸,同时除去油封的润滑剂,然后装配。 Oil seals for compressor mechanisms and parts are used during transport and long-term storage of the machine to ensure it is in good condition. Before installing the compressor at the site of operation must be unsealed. For this reason the compressor must be partially disassembled, with the oil-lubricated lubricant removed, and then assembled.
