为军工配套的一种高性能动密封装置最近由机械部通用机械研究所研制成功。这种装置要求在500米深水高压、双向运转下保证零泄漏，噪音小，结构上简单，装拆更换方便，易维护保养。针对这一要求，课题组采用了集装式组合密封，在两道密封之间形成“容漏空间”，让第一道密封在高 A high-performance dynamic seal device for military applications was recently developed by the General Machinery Research Institute of the Ministry of Machinery. This device requires 500 meters deep water pressure, two-way operation to ensure zero leakage, low noise, simple structure, easy assembly and disassembly, easy maintenance. In response to this request, the group adopted a combination of cartridge seal, the seal between the two forms a “leakage-tolerant space,” so that the first seal in the high
