Method for collimating oil contamination degree surveymeter on-line

Abstract

The invention relates to a method for improving a collimating method to an oil contamination degree surveymeter on-line which belongs to the measuring technique field. The method includes steps as follows: collimating a standard oil contamination degree surveymeter; connecting the standard oil contamination degree surveymeter with a collimated oil contamination degree surveymeter on line; settingan account channel of the standard oil contamination degree surveymeter and the collimated oil contamination surveymeter on line; adding a standard dust. The method has characteristic of the operation steps as follows: adding latex bead; verifying test table; processing collimating to the collimated oil contamination degree surveymeter. The method increases 70 mum particle diameter segment amounts in oil for according with stat rule, collimates the collimated oil contamination degree surveymeter 70 mum particle diameter segment and satisfies using requirement in fact testing.

Description

Calibration method of an online oil pollution degree detector technical field The invention belongs to the technical field of metering and relates to an improvement of a calibration method for an online oil pollution degree detector. technical background The online oil pollution degree detector can monitor the particle impurity content of the oil used in the hydraulic system in real time, such as the S50 online oil pollution degree detector of the German PAMAS company. It must be calibrated when it is used online. Since many of these online oil pollution degree detectors do not have a power system, they cannot be calibrated with the conventional international standard ISO11171. The current international method is to use the international standard ISO11943. The steps are as follows: 1. Calibrate the standard oil pollution degree detector; use the oil pollution degree detector that can be used both online and offline as the standard oil pollution degree detector, and calib...

Problems solved by technology

The disadvantage of the above calibration method is: because the pollutant dust used is ISOMTD standard dust, the number of particles with a particle size of 70 μm is very small, and the number of particles in every 10mL of oil is only 1-2. There is no statistical law, so calibration cannot be performed for this particle size segment

However, when using the online oil pollution degree detector to detect the actual oil, it is necessary to count the pollution particles with a particle size of 70 μm, because the online oil pollution degree detector has not calibrated this particle size section, resulting in detection errors Very large, can not meet the requirements of use
