出于質(zhì)量控制目的，對燃料的水分離特性進(jìn)行評級，以確定存在的表面活性材料（表面活性劑）的量。表面活性劑會降低用于從燃料中去除水分的過濾器分離器的性能。水的存在會損害發(fā)動機性能并引發(fā)微生物生長，從而導(dǎo)致油箱腐蝕和燃油管路過濾器堵塞。此外，出于質(zhì)量控制目的，燃料要經(jīng)過“透明和明亮”測試，以確定中間餾分油中游離水和顆粒物的含量。

1140型微型分離儀

儀器和測試說明

1140 型微型分離儀是一種機電儀器，用于執(zhí)行四項離散測試。ASTM標(biāo)準(zhǔn)測試方法D3948（煤油）、D7224（煤油）和 D7261（柴油）用于對水分離特性進(jìn)行評級，D4860（煤油或柴油）用于檢測游離水和顆粒污染并對其進(jìn)行數(shù)值評級。該儀器只需使用包含適當(dāng)聚結(jié)池的四個“六包”之一即可執(zhí)行上述四項測試中的每一項。

水分離特性

測試方法 D3948、D7224 和 D7261 采用基于第 5 版 API 認(rèn)證介質(zhì)的濁度計、機械混合器和一次性聚結(jié)器過濾器。樣品的一部分裝在透明玻璃瓶中，用于將儀表設(shè)置為讀數(shù)為 100。小瓶中的樣品被丟棄，小瓶被保留。

塑料注射器中樣品的另一部分用于使用混合器制造水/燃料乳液。乳液以編程速率通過過濾器，并將一部分收集在保留的小瓶中。在濁度計中更換小瓶，并對燃料的水分離特性進(jìn)行評級。

將獲得的值與用于將儀表設(shè)置為 100 的未處理樣品進(jìn)行比較。等級越高，100 為zui大值，表面活性劑含量越少。

游離水和顆粒物污染（透明和明亮）

測試方法 D 4860 將一部分樣品通過過濾介質(zhì)，過濾介質(zhì)收集在透明玻璃瓶中。將小瓶放入濁度計中，將儀表調(diào)整至100。處理后的燃料被丟棄，將一部分未處理的燃料放入小瓶中，然后重新插入濁度計。等級越高，zui大值為 100，表示游離水和顆粒物較少。

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.
