现我厂有一台泵,因为介质为热水90摄氏度,现用轴承黄油经常因为温度高而失效,造成轴承损坏。我想将黄油换成二硫化钼是不是可以解决这个问题。

能解决,主要是换成带水套的轴承箱,或者机封降温也可以,防止传热

用二硫化钼可以改善,另可考虑选择润滑油形式啊,加个自动润滑设置,成本也不大。

90度温度并不会很高,轴承故障的原因也不一定就是润滑脂的问题,不过建议下次换轴承时直接改用润滑油吧。

介质90度应该不是影响的主要原因,锂基脂的滴点我记得好像是170度左右吧,不要用钙基或钠基的黄油,改用锂基脂吧。

滚动轴承的话可以用钠基脂,适用最高110℃

高温润滑脂SHC220等~~

是定位端73系列背靠背的轴承吗

可以选用耐高温的润滑脂,完全没有问题。
