Problems solved by technology

For the speed control system, it will lead to corrosion and jamming of the parts of the speed control system, and the flexibility of the action of the parts will be reduced; for the lubrication system, it will destroy the lubrication function of the oil; affect the heat exchange of the oil cooler; affect the cooling of the bearing pad, so that the bearing pad near the bearing pad The oil is in a state of high temperature and overheating, which will accelerate the deterioration of the oil
At present, there are many regeneration treatment methods for deteriorating anti-fuel oil, but the treatment effect is not ideal, or the treatment effect is good, but the oil quality after treatment is unstable, and after a short period of operation, various indicators deteriorate rapidly.

Embodiment Construction

[0016] The present invention is described in further detail below in conjunction with accompanying drawing:

[0017] The method for improving the anti-deterioration performance of phosphate ester fuel oil comprises the following steps: weighing phosphate ester fuel oil, antioxidant and polar adsorbent, adding the polar adsorbent to the phosphate ester fuel oil, heating and stirring, Make the polar adsorbent fully contact with the phosphate ester anti-fuel, then filter out the polar adsorbent in the phosphate anti-fuel, then add the antioxidant, and finally stir evenly. Among them, the quality of the antioxidant is phosphate 0.5% of the quality of the fuel oil, the quality of the polar adsorbent is 2% of the quality of the phosphate ester anti-fuel, and the antioxidant is T501 antioxidant.

[0018] Pour the polar adsorbent into the phosphate-resistant fuel, heat it to 60°C and stir at a constant temperature for 1 hour to make the polar adsorbent fully contact with the phosphate...

Abstract

The invention discloses a method for improving degradation prevention performance of phosphate fire-resistant oil. The method includes following steps: weighing the phosphate fire-resistant oil, an antioxidant and polar adsorbent, adding the polar adsorbent in the phosphate fire-resistant oil, performing heating and stirring, fully contacting the polar adsorbent with the phosphate fire-resistant oil, and then filtering out the polar adsorbent in the phosphate fire-resistant oil, and then adding the antioxidant, and finally stirring evenly. The method can improve the degradation prevention performance of the phosphate fire-resistant oil.

Description

technical field [0001] The invention belongs to the technical field of fuel oil resistance and degradation prevention, and relates to a method for improving the fuel oil resistance and aging resistance of phosphate ester. Background technique [0002] Anti-fuel oil is the abbreviation of synthetic phosphate ester fire-resistant hydraulic fluid, which has excellent heat resistance, fire resistance and lubricity. With the continuous increase of the power of the generator set, the steam parameters and the oil pressure of the steam turbine speed control system are correspondingly increased. In order to prevent the high pressure oil from leaking and causing a fire, the control fluid of the steam turbine speed control system has been widely used to resist fuel oil. In order to provide a reliable safety guarantee for nuclear power units, some nuclear power plants not only use anti-fuel for the control fluid of the speed control system, but also use anti-fuel for the lubricating oil...
