["최근 우리 회사에서 사용 중인 다단 펌프의 비드라이버 방울轴承温度达到76摄氏度，使用的是46#润滑油，现在想改成68#润滑油，这样效果会好吗？"]

["다단 펌프의 방울轴承温度高，还要考虑其他因素，更换粘度高的润滑油会使轴承温度再次升高，没找到直接原因只更换润滑油是解决不了问题的。多级泵一般非驱动端轴承为定位轴承，也有安装推力盘的，运行时和平衡盘一起平衡轴运行平衡盘间隙过大或过小会使平衡盘平衡的轴向力减少而定位轴承要平衡的轴向力就会增加所以轴承温度会增加建议检查平衡盘间隙重新调整间隙。检定位端轴瓦间隙间隙过小过大也会温度高"

["蘇尔寿的多级泵就是这样的轴承温度大轴承承载了过多的轴向力所以温度高。建议更换平衡机构如果不行箱体加水冷！根本发发把平衡机构改成盘鼓结合的！"]
