A solution for the automatic determination of diesel acid
Acidity can reflect the influence of acidic substances (especially organic acids) in diesel on engine. In general, in the case of more acid and water, the oil supply parts are easy to be corroded, and there will be coking of the injector hole, increased carbon accumulation in the cylinder, and greater wear of the plunger of the fuel injection pump.
Acidity was determined by GB/T 258 method.
Summary of methods: Volumetric method. In this method, organic acids in light diesel oil are extracted from boiling ethanol and then titrated with 0.05n potassium hydroxide ethanol solution while hot. The number of ml of potassium hydroxide required to neutralize 100 ml of petroleum products is called acidity.
SH108B automatic acidity tester is designed and manufactured according to THE GB-T 264-1983 standard "determination of petroleum product acid number" and GB-T 7559-1987 standard "determination of transformer oil, turbine oil acid number in operation (BTB)", GB/T258 gasoline, kerosene, diesel acid determination method. Using true color LCD touch screen full Chinese man-machine dialogue interface, menu - oriented input, advanced technology, easy to operate. With automatic temperature control, automatic titration, automatic detection and automatic printing test results, automatic cleaning and discharge of waste liquid, so that the test process automation. Widely used in electric power, petroleum, commodity inspection, scientific research and other departments.
