本溪水泵厂和本溪轻化工研究所在研制高压往复泵柱塞密封填料中,经过三年多的探索与试验,从十余种填料中研制出BS-2号填料,其使用寿命达3200多小时。于一九八三年四月十五日通过省级鉴定,认为该填料是一种新型填料,经在3DS-7.5/200型高压往复泵上运行试验,在无油润滑条件下,已累计运转了3252小时,达到国内先进水平。本文着重介绍了BS-2号填料的试验研制过程及其使用性能。
Benxi Pump Factory and Benxi Light Chemical Research Institute in the development of high-pressure reciprocating pump plunger seal packing, after more than three years of exploration and testing, developed from more than ten kinds of filler BS-2 packing, the service life of up to 3200 hours . It passed the provincial appraisal on April 15, 1983 and is considered as a new type of packing. After running on the 3DS-7.5 / 200 high-pressure reciprocating pump, it has run accumulatively under oil-free conditions 3252 hours, reaching the domestic advanced level. This article focuses on the BS-2 filler test development process and its performance.
