This standard JB/T 51123-1999 classifies the quality of hydraulically driven centrifugal oil filters for internal combustion engines (22~735 kW) into three grades: qualified, first-class, and superior. It specifies performance indicators for each grade, including rotational speed, drive volume flow, output volume flow, sealing, cleanliness, and pressure resistance, along with corresponding test methods and inspection rules. Inspection follows sampling plans based on GB/T 2828, with judgment made by nonconformity categories (A, B, C). This standard provides a unified technical basis for quality evaluation of centrifugal oil filters for internal combustion engines.
本标准JB/T 51123-1999针对22~735 kW内燃机用液力驱动离心式机油滤清器，将产品质量分为合格品、一等品和优等品三个等级。标准详细规定了各等级的性能指标，包括转速、驱动体积流量、输出体积流量、密封性、清洁度、耐压强度等，并给出了相应的试验方法和检验规则。检验采用基于GB/T 2828的抽样方案，按不合格分类（A、B、C类）进行判定。该标准为内燃机离心式机油滤清器的质量评定提供了统一的技术依据。
