Translate the following. 高温泵抽送介质温度高达41℃,像这种高温介质泵轴承的稀油润滑,油池温度可达81℃,润滑油摩擦产生的热量传递不出去,磨擦表面的金属磨粒等机械杂质无法带走,增大磨擦、增加磨损,缩短设备使用寿命。采用纯油雾润滑,轴承腔内无润滑油,消除了因润滑油摩擦而产生的热量,使轴承运行温度下降11℃,也消除了因润滑油不断重复使用而含有水分或残渣的潜在危险,轴承的使用寿命延长3倍。沈阳佳益油雾技术有限公司于2204年在大连西太平洋石化常减压装置成功应用了油雾润滑系统,其中减压渣油泵P2为沈阳国特隆泵有限公司生产的的C-6型机泵,介质正常温度377℃,最高温度41℃,泵功率114KW,投入油雾润滑后,机泵表面温度下降1℃,延长了轴承的使用寿命。其中原油泵P为沈阳国特隆泵有限公司生产的的WSJH8×11-型机泵,电机功率63kw,泵功率66kw,一直成功运行至今,受到了用户的一致好评。立式泵轴承的润滑对轴封要求较高,而轴封的使用寿命又较短,即使采用脂润滑,轴承长期运行使温度升高,润滑脂老化变质、液化、挥发或流失,如果密封失效的话,上部部的油脂溶化后掉入轴承箱下部,导致下部轴承脱油而温度过高而烧毁。采用油雾润滑,解决上述安全隐患,而且机泵表面温度下降15℃,轴承的使用寿命延长3倍。

感谢分析,我们的高温泵也大多采用油雾润滑。
