Internal and External Broken Wire Tester Elevator Steel Wire Rope Fracture Elevator Wire Rope Testing
1. LF testing sensitivity of local injury detection
The detector detects the minimum metal cross-sectional area change and the minimum size of damage length corresponding to local damage.
2. LMA testing sensitivity of metal cross-sectional area loss detection
The detector detects the minimum metal cross-sectional area change and the minimum size of damage length corresponding to the loss of metal cross-sectional area.
3. LMA repeatability error of metal cross-sectional area loss
Within the range of the instrument and under the same detection environment and conditions, the maximum value of the random error obtained by repeated continuous measurement of the variation of the same metal section area in the same sample.
4. LMA linearity error of metal cross-section area loss
Within the range of the instrument, the absolute value of the maximum deviation between the measured curve of the metal cross-sectional area of the sample tested by the instrument and the measured value of the measured cross-sectional area of the group of metals.
5. LMA error of indication of metal cross-sectional area loss
Within the range of the instrument, the loss of the metal cross-sectional area measured by the instrument is subtracted from the actual loss of the metal cross-sectional area.
6. Linear error of Wire Rope LMA linearity error of metal cross-section loss
Within the range of the instrument, the absolute value of the maximum deviation between the metal cross-sectional area loss measured by the detector and the calibration curve fitted by a group of metal cross-sectional area loss measured by the instrument under the condition of the same metal cross-sectional area loss length.
7. Resolution of testing distance
The detector can detect the minimum distance of resolution.
8. Dual-function instrument
The detector can detect and show changes in the metal cross-sectional area loss (LMA) on one channel and local damage (LF) on the other. The signal recording device of this detector can be a computer, graph recorder or other matching equipment.
9. Single-function instrument
The detector cannot simultaneously detect and display the change of metal cross-sectional area loss and local damage, but can only detect and display one of them. The recording signal device of this detector can be computer, graph recorder or other matching equipment.
10. Wire rope electromagnetic tester
The principle and composition of the detector meet the requirements of GB/T 21837-2008 standard, and have the functions of detection distance display, data storage or recording.
Wire rope flaw detector is a collection of advanced flaw detection technology at home and abroad. Using digital processing and network technology, a portable intelligent wire rope electromagnetic nondestructive testing instrument is developed. It is widely used in mining, cableway, lifting equipment, elevator, port machinery, cable bridge and other fields.
Wire rope flaw detector can be real-time display of the internal and external broken wires, corrosion, wear, metallic cross-sectional area changes of quantitative values, according to the current standards and regulations make the diagnosis report and solutions, has realized the rapid diagnosis of wire rope damage, reduce double wire rope detection time, detection does not affect the normal production, solve the labor, low efficiency of inspection line, unable to test the internal damage and artificial factors and so on. The instrument is easy to carry, simple to operate, and can be operated by operators after simple training, with high detection accuracy, good repeatability and accurate damage location.
Full range of wire rope diameter range can be detected: Φ 1.5-300 - mm (need to configure different series specifications sensor)
Relative speed between sensor and wire rope: 0.0 -- 6.0 m/s best: 0.3 -- 1.5 m/s
The best gap between sensor guide sleeve and wire rope is 2 -- 6 mm, and the allowable gap is 0 -- 15mm
Broken wire defect (LF) detection capability
Qualitative: single concentrated broken wire qualitative detection accuracy is 99.99%
Quantification: the number of broken roots in a single place allows one or one equivalent root to misjudge
More than 100 times of quantitative detection with single centralized root breakage without error, the accuracy rate is ≥92%
Quantitative rate of change of metal cross section (LMA)
Permissible error of detection sensitivity repeatability: ±0.055%
