HRD100  Q&A

Q:Explain following technical terms, and give examples and ranges of values for each:

Noise Treshold Value, Wave magnification rate, Sampling interval, First threshold, Second threshold, Reference value of cross-sectional metallic area, Sensitivity of cross-sectional metallic area, Magnification of wave form, WPP, LMA0

A:First open the video, you can see the normal blue real-time detection line, and not a "straight line" (invalid data), there must be ups and downs.

The meaning of the parameters is as follows:

Title: It can be named according to the diameter or use of the wire rope, both in Chinese and English.

Left 1: Diameter: measured rope diameter

       2: Twisting length: 6 times the diameter of the wire rope

       3: Sampling interval: 1.88 (fixed distance), guide wheel diameter 60mm * 3.14 revolutions / 100pr encoding density

       4: Monofilament diameter: the diameter of the single filament in the outermost layer of the tested rope

       5: Cross-sectional area: the sum of the ferromagnetic parts of the tested rope (excluding hemp core, etc.)

4-5 How to get the value: A: Name brand information when purchasing the steel wire rope, B: Fill in the software help with reference to a similar structure

In terms of software, these two play the role of "precise quantification". In fact, the first threshold and the second threshold still prevail.

Right 1: The first threshold (qualitative) is to set the minimum damage threshold

          2: The second threshold (quantitative) is 80% of the first threshold

For example, if the vpp value measured between 10 times is 55-70, the first threshold is 50 and the second threshold is 40

          3: The standard value of metal cross-sectional area, used for fixed wear (this value is initially randomly calibrated). The scrap standard can be ignored when it is not worn as a standard. After saving the collected data with this value, the LMAO at the bottom is the value during analysis, and the wear can be analyzed after modification and substitution.

          4: sensitivity is 8

          5: Magnification is 3

4-5 does not need to be adjusted, and can be applied in many occasions.

The first threshold: The most accurate calibration method is to make a damage to the tested rope, and repeatedly measure the vpp value derived from it 10 times, which is the first threshold. However, there may be no conditions in actual operation, so it is concluded that after use in the field, many calibration empirical values are 3-4 times the diameter of the wire rope.

For example, the diameter is 20, and the first threshold is 60.

60-80 is the first threshold, which may be due to the range deviation of the empirical value, but the deviation of the equivalent of 1-2 wires will not affect the judgment of the scrap of the wire rope.

Q:1-During "Sampling", the VPP value is displayed as: x / y(example:16/24).What does“x”mean and what does“y” mean?

A: (x + y) / 2 = damage value (the first threshold reference value), which is the difference between the voltage changes measured at both ends of the damage (compared to the full saturation)

Q:During “Sampling”, an alert occurs when a value is exceeded.

This value corresponds to First Threshold, Second Threshold, or both?

A:The alarm is to issue an alarm when the value exceeds the first threshold.

Q:For example,Construction: 6X26 WS IWRC

Diameter: 19mm

Lay pitch: 121.6 mm

Metallic cross-sectional area: 173 mm2

Single wire diameter: 1.42 mm

We have created a defect representing 1 broken wire and another defect representing 3 broken wires.

Please suggest a starting value for the First Threshold, Second Threshold, and Reference Value of the cross-sectional area?

A:19mm rope parameter preset:

Left: 1: Diameter 19

        2: Pitch 114

        3: interval 1.88

        4: Regional software helps to look up the table, about 300

        5: Monofilament 1.4

Right: 1: First threshold 70

           2: second threshold 55

           3. Pre-input value of reference value 14000

           4: Sensitivity 8

           5: Magnification 3

Q:When click on Auto Analyze (in Broken Wire Analysis), nothing happens.How to do?

A:Two situations for automatic analysis:

a. After collecting the data, click Save to analyze immediately after saving. Please remember to click on each page to automatically analyze until the last page, and then you can analyze the report.

b. Before analyzing the data, you need to first select the parameters, open the saved file to be analyzed, and then repeat the A operation.

Note: Before analyzing, make sure that the collected data (blue undulation) is valid data, and then pay attention to analyze each page. If there is no damaged or invalid data, the test date and parameters will also be displayed in the report, but the damaged serial number and content are blank.

Q:After performing the Deterioration Analysis, there is no curve in the graph with our 2.9 meter cable-test.Is this caused by the length of the cable being too small? Should we have a cable longer than 5 meters for this to work?

A:The software has multiple versions. No matter which version, as long as it exceeds 2 meters, half of the data can be effectively analyzed normally.

Q:After having sampled and saved the file, is it possible to redisplay the blue real-time detection line image?

A: After saving the sampled data, it will not be displayed as a blue line sampled in real time. Instead, during analysis, it will appear like an ocean, with blue lines throughout the dialog. The distance length is indicated on both sides.

Q:How to know the state of charge of the batteries?

A:If the battery is dead, when the alarm circuit is turned on:

a. The green power indicator is off

b. The red warning light is always on

c. Alarm buzzer sounds continuously

It is recommended to charge the battery the day before use. The charger has indicator lights, a red light indicates charging, and a green light indicates that it is fully charged.

Q:Is the unwinding speed of the cable the detection speed?

A:In the software, when a blue line appears in real time, the current position (meters) can be displayed in real time. After the test, the total length of the whole meter is divided by the time used for the test. For example, if it detects 100 meters for 100 seconds, its rate is 1 meter per second. However, in order to ensure the stability of the test data and the artificial safety of the portable test, it is recommended that the detection rate should be below 0.1-0.3 m / s.
