油泵用石墨密封环生产过程质量控制研究

Study on the Production Process Quality Control of the Carbon Seal Ring for Oil Pump

油泵是运载火箭控制系统中电液伺服机构上的主要动力元件,油泵渗漏油会影响伺服机构的正常工作,油泵渗漏油主要原因之一为石墨环引起,该文介绍了石墨环在生产过程中的质量控制方法,主要包括原材料检查、制作标准样件、机加过程及装配过程进行控制,确保制造出满足要求的产品。

the oil pump is the main power elements for electro-hydraulic servo mechanism, which in control system of the launch vehicle s . oil leakage of the oil pump will effect the servo mechanism s working. one of the main reasons of the oil leakage is the carbon seal ring, this arctile introduce the quality control method of the carbon seal ring s produce process, conclude the raw material check、manufacture of the standard artifact、mechanical processing process and assembly process check, ensuring to manufacture the qualificated products.
