注意:在操作整个过程中,用镊子操纵过滤器。 NOTE: Handle filters with forceps at all times. 5.1.4 清洗轴承部件 Cleaning of bearing components
5.1.4.1 在清洗容器中倒入足够的溶剂,使一个轴承部件完全浸入溶剂中。清洗容器首选玻璃烧杯,但对大尺寸轴承,需要用不锈钢杯或盘。

Glass beakers are preferred but stainless beakers or trays are needed for larger size bearing. 5.3.2 在充分搅动中清洗轴承部件15秒,以便有效去除微粒和防腐剂。对装配后的内圈,为充分去除所有微粒和防腐剂,必须转动部件或溶液至少15秒。
Wash bearing components for 15 seconds to remove particles and preservative. For assembled cones, rotating the components in the solvent to remove particles and preservative.
5.1.4.2 从溶剂中取出轴承,然后用溶剂喷雾剂彻底喷洒至少10秒钟。在此期间,应边清洗边让冲洗物流入容器。对组装后的轴承应边转动边清洗。分开清洗每一个部件,然后立即干燥。最后用防锈材料如Quaker FERROCOTE 5856BF T1将轴承重新防护。 Remove the bearing from the solvent and wash thoroughly with a fine spray of hexane from the wash bottle for at least 10 seconds. During this step, all washing should drain into the container. Cone assemblies should be rotated. Wash each component and then immediately dry. preserve the bearing with Quaker FERROCOTE 5856BF T1
注意:轴承部件用一个过滤盘。由于溶剂烟雾是危险的,所以整个清洗过程必须在实验室环境下进行。不可接触皮肤。在整个操作过程中,可使用钳子或塑料手套处理轴承部件。但只有(经过含污量)证实的防尘手套可使用(聚乙烯手套)。避免使用已破损,有斑点的手套。
NOTE: Use one filter disk for five bearings. The cleaning procedure must be in the lab hood since the solvent fumes is hazardous. Use tongs or plastic gloves to clean the bearing component. Only gloves proven to be free of dirt (such as PE gloves) can be used 5.1.5过滤清洗后溶液 Filtering washing solvent
5.1.5.1 将事先已称重的0.45微米孔隙的滤膜,安放于微孔过滤器上。(上膜) Assemble Millipore filter with a pre-weighed 0.45um filter. (top filter) 5.1.5.2在实验滤膜下放置一张事先已称重的控制滤膜。(下膜) Insert a pre-weighed control filter beneath the test filter.(bottom filter)
5.1.5.3小心的将清洗后溶液倒入过滤漏斗,并用装有真空抽气装置的抽气瓶将溶液通过滤膜真空过滤。
Pour the solvent into the filter funnel carefully and apply vacuum to draw the solvent through the filter.

After filtered all solvent, wash the container four times with a wash bottle to remove particles. Then wash the walls of filter funnel. Remove clamp and spray outside of the funnel-base junction to draw in any oil collected there. Rewash funnel and disassemble. 5.1.5.5 释放真空后,用镊子移动滤膜盘,放置到干净平整的纸上晾干。
After releasing vacuum, use forceps to remove the filter disks. Place them on a sheet of flat paper for drying.
5.1.6 重新称重 Reweighing
5.1.6.1将滤膜放置在干燥箱中干燥15分钟,干燥温度为80-100℃(175-212℉)。 Place the filters in a oven at 80-100℃(175-212℉)and dry for 15 minutes. 5.1.6.2 从干燥箱中取出滤膜并冷却15分钟。 Remove from the oven and let the filter cool 15 minutes。 5.1.6.3 重新称重滤膜,精确到0.1mg。 Reweigh the filters to the nearest 0.1mg. 5.1.7 计算 Calculation
5.1.7.1用最终的测试滤膜重量,减去初始滤膜的重量。可减去控制滤膜增加重量或加上控制滤膜失去的重量,以修正每次的测试结果。用合成的总含污量除以参与试验的总部件数,就可得到每个部件的平均含污量。(如果用足够的洗液去除残油的话,控制滤膜增加的重量不应该超过0.5mg)
Subtract the initial weigh of the test filter from the final test filter weight. Then subtract weight gain or add weigh loss of control filter as a correction factor for each test result. Divide the resultant total dirt count by the number of components used in the test to obtain the average dirt content of each component.(The weight increase of the control filter should not exceed 0.5mg if adequate washing is used to remove oil residue)
