Classification standard for particle pollution degree of power oil
1 Scope
This standard specifies transformer oils, turbine oils, phosphate ester fire-resistant oils, gear oils for wind generators, and power plant auxiliary equipment for the power industry.
Grading method for particle pollution degree of oil and other oil products.
This standard is applicable to the classification of particle contamination determined by the automatic particle counter and microscope method of oil.
2 Normative references
The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article
Pieces. For undated references, the latest version (including all amendments) applies to this document.
3 Terminology
The following terms and definitions apply to this document.
3.1
Particle Size
The diameter of the solid particle pollutants in the oil. The particle size in the ISO 4402 standard is the maximum length of the particle, and the particle size in the GB/T 18854 standard
Is the diameter of the circle equivalent to the projected area of the particle.
3.2
Pollution level
The pollution degree of particles in the oil is determined by the number of particles within the specified particle size range in 100 mL of oil.
3.3
Pollution code
The pollution levels of oil products in the five different particle size ranges described in Table 1 are composed of a series of five numbers separated by slashes.
3.4
Pollution level
The pollution code represents the largest number of pollution levels.
4 Grading method of particle pollution degree
4.1 Determination of pollution level
4.1.1 According to DL/T 432, detect the number of particles within the 5 particle size ranges shown in Table 1 per 100 mL of oil.
4.1.2 Determine the pollution level corresponding to each particle size range according to Table 1.
4.2 Determination of pollution degree
4.2.1 Determine the pollution code based on the pollution level found in 4.1.2.
4.2.2 Take the value of the maximum pollution level in the pollution code as the particle pollution level of the test oil.
For example. Table 2 lists the number of particles measured in the five particle size ranges of oil products, as well as the pollution level and pollution generation determined according to Table 1.
Code and pollution level. The pollution code of this oil is 9/8/9/7/8, and the maximum pollution level in the pollution code is 9, so its pollution level is 9.
