Overview
HK-3160SZ Automatic Acid Value Tester
Product Details
HK-3160SZ Automatic Acid Value Testeraccord with《GB/T264-1983 Determination of Acid Value of Petroleum Products《GB/T28552-2012 Determination of Oleic Acid Value of Transformer Oil and Turbine Oil (BTB Method)Mainly used for measuring the oleic acid value of transformer oil and turbine oil.
The definition of acid value: Under certain conditions, the milligrams of potassium hydroxide required to neutralize one gram of acidic components in the test oil is the acid value of the test oilmg KOH/gexpress. The acid value usually measured in oil testing is the sum of organic and inorganic acids, also known as the total acid value.
The significance of measuring acid value: There are a large number of oil filled electrical equipment in power systems and industrial and mining enterprises, and acid value is one of the main control indicators for the degree of oil aging during operation. According to the size of the acid value, the amount of acidic substances contained in the oil can be determined. Generally, the higher the acid value, the more acidic substances are contained in the oil. Due to the influence of oxygen, temperature, and other conditions during operation, oil will gradually oxidize to produce a series of oxidation products. Among these oxidation products, acidic substances are more harmful, which can improve the conductivity of the oil, reduce its insulation, and shorten the operating life of the equipment. In addition, acidic substances in oil can also corrode metal materials such as copper, iron, and aluminum used in equipment components, and the generated metal salts are catalysts for oxidation reactions, which can accelerate the aging process of oil. The higher the acid value of the turbine oil, the more it indicates that the oil has aged deeply. The formation of cyclic acid soaps in the oil can promote oil emulsification, damage the lubrication performance of the oil, cause wear and heat generation of the components, and affect the safe operation of the unit. Therefore, the acid value in oil testing is of great significance for production, use, storage, and other aspects, and is a key indicator to determine whether the product is qualified.
The HK-3160SZ automatic acid value analyzer is used for measuring the acid value of transformer oil, turbine oil, fire-resistant oil, etc. The instrument is controlled by an embedded system and displayed on a large touch screen. Chinese and English menus are optional, and the electrical, optical, mechanical, and chemical integrated fully automatic design allows for automatic measurement and printing, and continuous measurement as needed1to6The cup oil sample completely replaces manual operation, improves work efficiency, reduces the labor intensity of workers, and minimizes the harm of organic solvents and chemicals to the human body. Moreover, the instrument is easy to operate, convenient to use, has strong anti-interference ability, stable and reliable, and can meet the needs of refineries, power plants and scientific research units. It is one of the essential instruments for oil analysis and quality inspection.
working principle:It's based on《GB 264-1983 Determination of Acid Value of Petroleum Products《Designed according to GB/T 28552-2012 "Determination of Oleic Acid Value of Transformer Oil and Steam Turbine Oil (BTB Method)" (GB/T 7599-1987 "Determination of Oleic Acid Value of Transformer Oil and Steam Turbine Oil in Operation (BTB Method) has been abolished), its working principle is to inject a fixed volume of extraction solution each time, then add a known mass of sample, stir and extract, and then titrate with 0.02-0.05mol/L potassium hydroxide ethanol solution until the solution shows a significant color change as specified by the national standard (when using BTB indicator, the endpoint of neutralization titration is the solution changing from yellow to blue-green). Record the number of milliliters of potassium hydroxide ethanol solution consumed to calculate the acid value of the sample.
◆ Using the principle of neutralization titration, the extraction solution injection, stirring, neutralization titration, determination of titration endpoint and display of measurement results are automatically completed, and the measurement results are automatically stored and printed
◆ Adopting a 7-inch 800x480 touch screen, the human-computer interaction interface is simple and convenient to operate
◆ The neutralization titration dosing method uses gas displacement instead of traditional peristaltic pump dosing, resulting in more accurate measurement
◆ The measuring sensor adopts imported components, which are not affected by external environmental light interference and have stable and reliable performance
◆ Special reagent bottles are used to contain extraction and neutralization solutions. The reagents do not come into contact with air during use, avoiding solvent evaporation and the influence of CO2 in the air
◆ At low temperatures, automatic temperature control can be enabled to keep the internal temperature of the instrument constant at 30 ℃, ensuring normal measurement of the instrument
◆ Can perform continuous automatic detection on 1-6 oil samples
◆ The instrument has self checking and alarm functions
◆ Standard Ethernet interface (compatible with LIMS system) and USB communication interface, optional RS-232 serial port
◆ Can store 1000 test records, and can be viewed, printed, and exported by operation date
