“社会主义到处都在胜利地前进”。石油工业形势也是一派大好。无产阶级文化大革命以来,我国原油产量成倍增加,技术水平空前提高,对机械设备提出了更新更高的要求。现有油矿用往复泵落后于钻采工艺要求成为钻采机械行业中一个关键问题。其中高冲数压裂泵的泵阀寿命低尤其是一个突出的问题,泵阀还限制了钻井泵等其他矿用往复泵的进一步发展,急需加以研究解决。本文拟对此作些粗浅的讨论。由干作者水平很低,错误难免,欢迎批评指正。 “Socialism is triumphantly everywhere.” The situation in the oil industry is also fantastic. Since the Great Proletarian Cultural Revolution, the output of crude oil in our country has doubled and the technical level has been raised unprecedentedly. As a result, new and higher requirements on machinery and equipment have been put forward. The existing oil-mine reciprocating pumps lag behind the drilling process requirements to become a key issue in the drilling machinery industry. Among them, the low life of the high-pressure fracturing pump valve is a prominent problem in particular. The valve also limits the further development of other mining reciprocating pumps, such as drilling pumps, and urgently needs to be studied and solved. This article intends to make some superficial discussions. Low level by the dry author, the mistake is inevitable, welcomed the criticism.
