Fuel oil total sediment analyzer

Fuel oil total sediment analyzer model:HAD-0701/0702

This instrument is based onSH/T0701andSH/T0702Determination method for total sediment of residual fuel oil (aging method, thermal filtration method))》Standard design and manufacturing. This method is suitable for determining100The viscosity at ℃ is less than55mm2/sThe total sediment in the blended fraction of residual fuel oil and fraction fuel oil containing residual components.

Sampling range for precision assessment: The maximum total sediment of residual fuel oil is0.50%(m/m),The maximum total sediment of distillate fuel oil containing residual components is0.40%(m/m).

This instrument requires the temperature of the sample to be maintained during filtration100The old-fashioned method of using steam insulation at ℃ is difficult to control the steam pressure, poses a high risk, and is prone to scalding people; Our company's products use electric heating insulation to ensure that the temperature of the sample meets the standard requirements during filtration, the oil sample does not solidify, and can be filtered by suction; At the same time, it ensures the sealing of the sample during vacuum filtration, with accurate filtration without residue or vacuum leakage.

This instrument is used for petrochemical processingSH/T0701andSH/T0702Two instruments integrated into1One instrument, aging method and thermal filtration method, all completed with one instrument. The quality level meets the requirementsISO10307-1andISO10307-2The level.

The instrument adopts imported glass fiber filter membrane, which ensures accurate and error free filtration and weighing.

1The instrument is a monolithic structure, with the front part being the sampling section,The latter part is the circuit control part.

2It can simultaneously test two samples or conduct parallel tests for ease of operation.

3Using a digital temperature controller for temperature control, the temperature control accuracy can reach ±0.1℃, its temperature display is intuitive, the reading is accurate, and it can also adjust the error caused by the aging of the temperature sensor.

4The timer adopts a digital display timer, and the timing can reach up to99h99m99s.

5The vacuum degree can reach40KPa±2 KPa,The vacuum degree is precisely displayed by a pressure gauge, and the vacuum pressure is adjusted by a precision regulating valve

6The aging bath is formed using a metal bath mold, which is safe and environmentally friendly. The sampling unit is operated with four holes. The panel is made of stainless steel, which makes the entire sample making process clean, tidy, and easy to clean, bringing great convenience to the operators.

7The metal bath is heated by an electric heating rod and controlled by a solid-state relay (the advantage of solid-state relays is that they have no obvious contacts and belong to soft control),High safety factor and high accuracy.

8The instrument uses a metal bath instead of a steam generator, making operation safer, simpler, and more environmentally friendly.
