江都三站于1982年首次试验应用了水润滑P_(23)酚醛塑料导轴承。经过了接近一万小时的运行考验,运行正常,稳定可靠,维护简单。并于1983年3月和1984年12月对3~#和8~#机进行解体检查,导轴承的磨损情况良好。泵轴轴颈的不锈钢护面很光滑,无任何磨损的痕迹,也无任何锈蚀剥落现象,只是光亮度略有差别。而轴承间隙与安装时间隙相相比较,发现经过三年运行后的间隙反而变小,分析化为这是由于塑料浸水膨胀的结果。泵轴轴颈由三年前的φ350~(-0.28)毫米,
Jiangdu three stations in 1982 for the first time test the application of water lubricated P_ (23) phenolic plastic guide bearing. After nearly 10,000 hours of running the test, the operation is normal, stable and reliable, easy to maintain. And in March 1983 and December 1984 3 ~ # and 8 ~ # machine disintegration inspection, bearing wear is good. Pump shaft journal stainless steel cladding is smooth, without any signs of wear and tear, nor any rust peeling phenomenon, but a slight difference in brightness. The bearing clearance and installation time gap compared to the gap after three years of operation found to be smaller, the analysis into this is due to the expansion of plastic flooding results. Pump shaft journals from the three years ago φ350 ~ (-0.28) mm,
