美国EMCEE 1140型便携式微量水分离指数测定仪1140 MARK X

产品说明书

出于质量控制目的，对燃料的水分离特性进行评级，以确定存在的表面活性材料（表面活性剂）的量。表面活性剂会降低用于从燃料中去除水分的过滤器分离器的性能。水的存在会损害发动机性能并引发微生物生长，从而导致油箱腐蚀和燃油管路过滤器堵塞。此外，出于质量控制目的，燃料要经过“透明和明亮”测试，以确定中间馏分油中游离水和颗粒物的含量。

1140型微型分离仪

仪器和测试说明

1140 型微型分离仪是一种机电仪器，用于执行四项离散测试。ASTM标准测试方法D3948（煤油）、D7224（煤油）和 D7261（柴油）用于对水分离特性进行评级，D4860（煤油或柴油）用于检测游离水和颗粒污染并对其进行数值评级。该仪器只需使用包含适当聚结池的四个“六包”之一即可执行上述四项测试中的每一项。

水分离特性

测试方法 D3948、D7224 和 D7261 采用基于第 5 版 API 认证介质的浊度计、机械混合器和一次性聚结器过滤器。样品的一部分装在透明玻璃瓶中，用于将仪表设置为读数为 100。小瓶中的样品被丢弃，小瓶被保留。

塑料注射器中样品的另一部分用于使用混合器制造水/燃料乳液。乳液以编程速率通过过滤器，并将一部分收集在保留的小瓶中。在浊度计中更换小瓶，并对燃料的水分离特性进行评级。

将获得的值与用于将仪表设置为 100 的未处理样品进行比较。等级越高，100 为值，表面活性剂含量越少。

游离水和颗粒物污染（透明和明亮）

测试方法 D 4860 将一部分样品通过过滤介质，过滤介质收集在透明玻璃瓶中。将小瓶放入浊度计中，将仪表调整至100。处理后的燃料被丢弃，将一部分未处理的燃料放入小瓶中，然后重新插入浊度计。等级越高，值为 100，表示游离水和颗粒物较少。

Model 1140 Micro-Separometer

For quality control purposes, water separation characteristics of fuels are rated to determine the amount of surface active materials (surfactants) present. Surfactants degrade the performance of filter separators used to remove water from the fuel. The presence of water can impair engine performance and initiate microbiological growth, which can cause corrosion in tanks and filter plugging in fuel lines. Also for quality control purposes, fuels are subjected to “Clear & Bright” tests to determine the amount of free water and particulate matter in mid-distillates.

Description of Instrument & Tests

The Model 1140 Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests. ASTM Standard Test Methods D3948 (Jet), D7224 (Jet) and D7261 (Diesel) are used to rate water separation characteristics and D4860 (Jet or Diesel) detects and numerically rates free water and particulate contamination.  This instrument performs each of the four tests above simply by using one of the four “Six Packs” containing the proper coalescer cells.

Water Separation Characteristic

Test Method D3948, D7224 and D7261 employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter based on 5th edition API certified media. A portion of the sample, in a clear glass vial, is used to set the meter to read 100. The sample in the vial is discarded and the vial is retained.

Another portion of the sample in a plastic syringe is used to create a water/fuel emulsion using the mixer. The emulsion is passed through the filter at a programmed rate and a portion is collected in the retained vial. The vial is replaced in the turbidimeter and the water separation characteristic of the fuel is rated.

The value obtained is compared to the unprocessed sample that was used to set the meter to 100. The higher the rating, 100 being the maximum, the less surfactant present.

Free Water and Particulate Contamination (Clear& Bright)

Test Method D 4860 passes a portion of the sample through a filter medium, which is collected in a clear glass, vial. The vial is placed in the turbidimeter and the meter is adjusted to 100. The processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the turbidimeter. Higher ratings, 100 is maximum, indicate that there is less free water and particulate present.

“Six Pack” Test Expendables Including Coalescer Cells

A box commonly known as a “Six Pack” that contains six test kits is shown. Each Test Kit contains vacuum packed expendables that are used to perform a single test. Each coalescer/filter is labeled to identify the type of fuel and the applicable ASTM method to be used. A container of distilled water is also included in each Six Pack to perform water separation tests.
