Preparation of oil leakage proof parts in determination of sulfur content in heavy oil by X-ray method
The determination of sulfur content in heavy oil adopts the principle of energy dispersion and the Microcomputer Design of mechatronics, so the analysis is fast and accurate. Its repeatability and reproducibility meet the relevant requirements of the national standards gb/t17040 and gb11140 and the petrochemical industry standard sh/t0742. The SH407 heavy oil X-ray sulfur content tester also fully meets the requirements of the more stringent American national standard astmd4294-02. It provides an important means for the detection of sulfur content in crude oil or petrochemical production. The instrument itself is green and environmentally friendly, and its price is only a fraction of that of imported instruments
Preparation of oil leakage proof parts
The oil leakage prevention part is composed of inner ring, outer ring and polyester film, which is set to prevent the oil in the sample cup from leaking to the instrument probe. It is always used in the use of the instrument.
1. place the oil leakage proof steel inner ring in the large concave circle of the pressure seat, with the small round base of the inner ring facing upward, and then place the polyester film in the middle on the small round bottom of the inner ring, as shown in figure (a);
2. put the oil leakage proof outer ring sleeve on the inner ring with film, and press it slightly after placing it properly; See figure (b);
3. press the outer ring to the bottom with the gland, as shown in figure (c);
4. remove the gland, remove the oil leakage proof parts from the pressure seat, and observe the polyester film. If it is tight and flat, it meets the requirements. Cut off the excess polyester film of exposed parts for standby; See figure (d);
