Vacuum spray dryerThe detection of leakage rate and parameter calibration are key steps to ensure its stable performance and operational efficiency. The following is a detailed analysis of these two aspects:

1、 Leakage rate detection

Leakage rate detection aims to identify potential leaks in equipment to ensure its vacuum performance. Common detection methods include:

1. Static voltage boosting method:

Easy to operate, it can determine the total leakage degree of the equipment.

Before testing, it is necessary to clean and dry the container being tested to reduce the impact of air release.

By observing the changes in pressure over time, the leakage rate can be calculated.

2. Bubble leak detection method:

Including sink bubble leak detection method and soap film bubble leak detection method.

By injecting a certain pressure of test gas into the inspected object and observing the formation of bubbles in the displayed liquid, the location of the leakage hole and the estimated leakage rate can be determined.

3. Mass spectrometry leak detection method:

A helium mass spectrometer leak detector is a specialized instrument used for leak detection.

By detecting the leakage of gas (such as helium), the location of the leakage hole can be determined and the leakage rate can be calculated.

2、 Parameter calibration

Parameter calibration is to ensureVacuum spray dryerThe key steps for accurate parameters include leak rate calibration. The following is the general process for parameter calibration:

1. Prepare calibration equipment:

The calibration system usually consists of standard leak holes, shut-off valves, and leak detectors that need to be calibrated.

Standard leak holes should have known and accurate leak rate values for calibrating leak detectors.

2. Perform calibration operation:

Connect the standard leak hole to the leak detector system.

Run the leak detector and wait for the leak rate reading to stabilize before reading the leak detector reading for the standard leak rate.

Perform multiple measurements (such as three times) on the same standard leak hole, calculate the average reading of the leak detector, and obtain the indication error between the standard leak rate and the average reading of the leak detector.

Connect other levels of standard leakage holes to the leak detector system in sequence according to this method for testing, and obtain the indication error of the leak rate of the leak detector at each level.

3. Processing calibration results:

If there is a significant deviation in the test results, the self calibration function of the leak detector can be considered for adjustment.

After calibration is completed, the calibration results should be recorded and used for subsequent equipment maintenance and performance evaluation.

4. Precautions:

During the calibration process, it should be ensured that the equipment is in a stable working state.

Calibration should be carried out in accordance with relevant industry standards or manufacturer's recommendations.

The calibration results should be recorded and saved in a timely manner for future reference and analysis.
