注水泵润滑油应用现状及发展趋势

Application Status and Development Trend of Lubricating Oil for Water Injection Pump

柱塞式注水泵应用广泛,其对润滑油有较高的要求,但目前国内外还没有规范的用油标准。根据注水泵的结构特点、工作原理以及其在石油化工领域使用的工况条件及运行特点,对注水泵的润滑要求、用油现状及发展趋势、常用润滑油的性能特点等进行分析,发现常用的CD级柴油机油、齿轮油等不适合注水泵的工况要求。而注水泵专用油产品,以其良好的抗乳化、抗氧化、抗磨损性能,满足了油田注水泵润滑系统的特殊使用工况要求。

Plunger water injection pump is widely used,and it has higher requirements for lubricating oil,but there is no standard for the use of its lubricating oil at home and abroad.According to the structure characteristics,working principle,working conditions and operating characteristics of water injection pump in petrochemical field,through the analysis of lubrication requirements,current situation and development trend of lubricating oil of water injection pump and performance characteristics of commonly used lubricants,it is found that the commonly used CD-grade diesel engine oil and gear oil are not suitable for the working conditions of water injection pump.The special oil products for water injection pumps,with their good anti-emulsification,anti-oxidation and anti-wear properties,meet the special operating conditions of oilfield water injection pump lubrication system.
